The 50 Largest Family Offices in the World (2026)

Altss tracks 9,000+ family offices globally through continuous intelligence operations. Every family office listed below has a dedicated profile on Altss with verified contacts, investment mandates, and activity signals.

Key Findings

The 50 largest family offices in the world collectively manage an estimated $2.4 trillion in assets — roughly equivalent to the GDP of France. The landscape has shifted meaningfully over the past 24 months: technology founders now control seven of the top ten offices, Asia-Pacific is the fastest-growing region for new single-family office formation, and direct investment has overtaken fund allocations as the dominant deployment strategy among the largest offices.

Among the top 50:

• 32 are single-family offices (SFOs), 11 are family-controlled holding companies with dedicated investment arms, and 7 are hybrid structures.
• 28 are headquartered in North America, 13 in Europe, 6 in Asia-Pacific, and 3 in the Middle East.
• The median year of establishment is 2001, though the oldest (Grosvenor Estate) traces its roots to the 17th century.
• Private equity is the dominant allocation across the top 50, averaging 27% of portfolios, followed by public equities (22%), real estate (18%), and venture capital (12%).
• The top 10 alone control over $1.5 trillion — more than the combined AUM of the bottom 40.

Family offices tripled in number between 2019 and 2023, growing from approximately 1,285 to over 4,500. As of 2026, the total global family office count exceeds 8,000, with Altss tracking 9,000+ verified offices including those below the radar of legacy databases. Across the offices Altss monitors, 60% expect to hand leadership to the next generation within the coming decade — a structural shift that will reshape allocation behavior across the top 50 and beyond.

Altss intelligence across 300+ family offices globally indicates a global trade war has emerged as the number one investment risk for 2025-2026, overtaking geopolitical conflict. Offices are responding by increasing allocations to developed market equities (planned 29% for 2025, up from 26% in 2024), doubling private debt allocations from 2% to 4%, and reducing cash holdings as capital gets deployed. Geopolitical uncertainty is the most important issue for 84% of family offices, with overall sentiment turning negative for the first time since 2020 — 60% of offices are now pessimistic about the global outlook.

The Top 50 Ranking

Tier 1 — The Mega Offices ($100B+ AUM)

1. Walton Enterprises LLC

Estimated AUM $225 billion Headquarters 110 NW 2nd Street, Bentonville, Arkansas 72712 Wealth Creator Sam Walton (Walmart) Founded 1953 (entity); 1983 (family office operations) Type Single-Family Office — hub-and-spoke structure Key People Jim C. Walton (Chairman); Greg Penner (Walmart Board Chairman) Team WIT LLC (Walton Investment Team, commenced 2020) manages public equities Primary Sectors Retail equity, private equity, venture capital, impact investing, philanthropy Altss Profile View on Altss

The largest family office in the world by AUM. Walton Enterprises (WEI) manages the fortune of the descendants of Sam Walton, who founded Walmart in 1962. The family holds approximately 43% of Walmart's outstanding shares through Walton Enterprises and the Walton Family Holdings Trust — formed in April 2015 and receiving a transfer of 14% of Walmart outstanding shares from WEI in March 2020. Total family ownership is approximately 50% of Walmart. With Walmart's market capitalization exceeding $680 billion (January 2026), this concentrated position is the single largest wealth block held by any family office globally.

Individual Walton net worths vary significantly: Jim Walton ($146B, Bloomberg April 2026), Alice Walton ($133B), Rob Walton ($114B), and Lukas Walton ($48B). Combined family net worth exceeds $280B.

WEI operates a hub-and-spoke model: the central entity pools capital for economies of scale, while satellite offices manage individual family members' priorities. The investment arm, WIT LLC, commenced operations in 2020 and manages approximately $5B in public equities — primarily low-cost ETFs including Vanguard FTSE Emerging Markets ETF and Short-Term Treasury ETFs, alongside direct stakes in Apollo Global Management, Snowflake Inc., and Pinduoduo. Additional direct investments include FoodMaven (Series B, December 2019).

The Walton Family Foundation is the primary philanthropic vehicle, awarding over $700 million in grants annually. Focus areas: K-12 education reform, environmental conservation, and economic development in northwest Arkansas.

Satellite Family Offices:

Builders Vision · Principal: Lukas Walton · Focus: Impact/climate · Key Detail: $15B+ deployed in impact investing. Sectors: oceans, energy transition, agriculture. ~30-person investment team. CIO: Noelle Laing (promoted 2025 after Rebecca Carland departed for Knight Foundation). $1.7B foundation endowment, 90% mission-aligned by 2022 Madrone Capital Partners · Principal: Rob Walton · Focus: Late-stage PE, energy tech · Key Detail: Largest shareholder in StubHub. Investments include N5 Now, Cue, Brax, Uplift, and Achates Power Zoma Capital · Principal: Ben Walton · Focus: Sustainable solutions · Key Detail: Geographic focus: Colorado, Chile. Investments in energy/development projects and Uplight (cloud platforms for energy providers) RZC Investments · Principal: Steuart & Tom Walton · Focus: Consumer, outdoor, healthcare, fintech · Key Detail: Permanent capital deployed across venture, growth, and buyout stages

Tax and Structure Intelligence: Sam and Helen Walton transferred 80% of WEI to their children early, with the remaining share going to charities. Charities received minority interest while voting rights stayed with the family — a structure that avoided substantial gift and inheritance taxes. WEI retained Patton Boggs to lobby on tax matters, supporting private foundation reforms rather than direct estate tax repeal.

Why it matters for capital raisers: Walton Enterprises is a significant limited partner in PE and VC funds but increasingly favors co-investment rights and direct investment deal flow. Fund managers with exposure to sustainable infrastructure, food systems, or education technology are most aligned with the family's current investment mandate. The family's multi-office structure means capital raisers should identify which specific Walton entity matches their strategy — not pitch "the Waltons" generically.

2. Excession LLC

Estimated AUM $630 billion+ (Bloomberg, April 2026 — highly volatile — concentrated in founder stakes) Headquarters 1701 Directors Blvd., Suite 300, Austin, TX (Southpark One) Wealth Creator Elon Musk (Tesla, SpaceX-xAI) Founded 2016 Type Single-Family Office Key People Jared Birchall (Managing Director) Employees ~2 core staff; up to 80-100 including financial analysts Primary Sectors Public equity (Tesla), aerospace, AI, neural interfaces, tunneling Altss Profile View on Altss

Excession LLC manages Elon Musk's personal and financial affairs. This is not a traditional family office — it functions as a compact executive office that mobilizes capital and counsel around Musk's operating roadmaps across his portfolio companies. The AUM estimate is extraordinarily volatile: Musk's net worth stands at $630B (Bloomberg, April 7, 2026) after peaking at $839B (Forbes, March 2026) — making him the first person in history to surpass $800B. The primary driver was the SpaceX-xAI merger in February 2026 that valued the combined entity at $1.25 trillion. SpaceX filed confidential IPO paperwork in April 2026, targeting a valuation of $1.5 trillion+. The registered address at Southpark One in Austin is shared with Registered Agent Solutions — a privacy structure.

Key Personnel — Jared Birchall: Born 1974, Modesto, California. BYU graduate (1999). Career path: Goldman Sachs analyst (1999-2000) → Merrill Lynch wealth advisor (2000-2010; departed after being cited for sending correspondence to a client without management approval) → Morgan Stanley SVP (2010-2016) → Excession Managing Director (2016-present). Birchall simultaneously serves as CEO of Neuralink (administrative, not operational), CFO of xAI, CFO of The Boring Company, board member of the Musk Foundation, board member of the Dogecoin Foundation, and board member of the Ad Astra school. He exclusively manages Musk's cryptocurrency trades (per July 2023 court filing) and advised the Trump transition team on space policy and AI following the 2024 election. Resides in Austin, Texas; purchased a $2.25M home in 2020.

Portfolio Company Valuations:

Tesla (TSLA) · Valuation: ~$1.14 trillion market cap (April 2026) · Musk's Position: ~13% ownership stake (~$148B), plus restored 2018 compensation package (304M options at $23.33 strike) SpaceX-xAI (merged Feb 2026) · Valuation: $1.25 trillion combined; SpaceX filed IPO paperwork April 2026 targeting $1.5T+ valuation · Musk's Position: ~42% ownership stake. IPO expected to be the largest in history Neuralink · Valuation: Private, undisclosed · Musk's Position: Founder The Boring Company · Valuation: Private, undisclosed · Musk's Position: Founder X (formerly Twitter) · Valuation: ~$15-20 billion estimated · Musk's Position: Folded into SpaceX-xAI entity in Feb 2026 merger

Investment Philosophy: Musk has stated he "is not an investor" and only owns securities of companies he founded or controls. External LP tickets from Excession are rare — the bar is strategic adjacency, meaning the investment must directly de-risk a Musk roadmap in areas such as compute/power, robotics, launch/space-data, or advanced manufacturing.

Philanthropy: Musk Foundation held approximately $536M in total assets (FY2023), with $237M in expenses (IRS 990-PF). Year-end 2024: gift of 268,000 Tesla shares (~$108M) to unnamed charities. Giving follows "lumpy payout ratios" — gifts concentrated in liquidity years.

Key Risk Intelligence: September 2025 internal turmoil at xAI: departures of CFO Mike Liberatore, co-founder Igor Babuschkin, and General Counsel Robert Keele — reported clashes with Birchall and investor John Hering. Multiple ongoing securities class actions including Oklahoma Firefighters Pension v. Musk (re: Twitter stock purchases) and Rasella v. Musk.

Why it matters for capital raisers: Excession is not a typical LP. The office does not actively allocate to external fund managers or participate in traditional commitment pacing programs. Relevance is limited to companies operating in Musk's direct interest areas — AI, energy, tunneling, neural interfaces, space — seeking strategic capital rather than financial investors.

3. Cascade Investment LLC

Estimated AUM $169 billion ($102B personal wealth + $67B Gates Foundation Trust) Headquarters Kirkland, Washington Wealth Creator Bill Gates (Microsoft) Founded 1994 Type Single-Family Office / Private Holding Company Key People Michael Larson (CIO, since 1994) Employees ~100 professionals 13F Portfolio $41.8B across 25 holdings (Q1 2025) Primary Sectors Public equities, real estate, energy, hospitality, agriculture, waste management Altss Profile View on Altss

Cascade Investment manages Bill Gates's personal wealth alongside assets for the Bill & Melinda Gates Foundation Trust. The name "Cascade" was chosen intentionally to operate without drawing attention. The office succeeded Dominion Income Management, which was managed by Andrew Evans (later convicted of securities fraud). Larson started managing Gates's $11.5B fortune in 1994 as the sole employee and has delivered average annual returns of approximately 11% in the early decades.

Key Personnel:

Michael Larson · Role: Founder & CIO (since 1994) · Background: Born October 1959, Sacramento, CA. Raised Albuquerque. Graduated Valley High in 2 years.

In Q1 2025, initiated a new position in West Pharmaceutical Services (WST): 444,500 shares (~$99.5M). Core 13F holdings historically include Microsoft (~1% remaining), Berkshire Hathaway, Republic Services (~110M shares), Canadian National Railway, Ecolab, Deere, and AutoNation.

Private and Real Asset Portfolio:

Asset Detail Four Seasons Hotels 71.3% ownership — increased from 47.5% in 2021 by purchasing half of Prince Alwaleed bin Talal's share for ~$2.21B. Company valued at approximately $10B. Originally invested in 1997 when Four Seasons was public. Robert Fritz serves as Lead Director. Cascade doubled down during COVID hospitality stress US Farmland ~269,000-275,000 acres across 17 states — the largest private farmland owner in the United States. Acquisitions began ~2013. Managed via subsidiary Los Arboles Management Republic Services ~110M shares (mid-2023).

Serves as renewable forest resource and inflation hedge Personal Real Estate Gates's 66,000 sq ft Medina estate (bought $2M in 1988, now valued at $130M+), 314-acre Belize island, $43M San Diego mansion. Total personal RE portfolio estimated at $160M+ (2024)

Board Seats (Larson): Western Asset (Chairman), Hamilton Lane, Ecolab, Republic Services, AutoNation (current and former).

Investment Philosophy: "Preserve and grow wealth to support Gates's philanthropic and personal objectives." Long-term value investing in essential industries with durable competitive advantages. Anchor stakes held through downturns. No public intake process for managers.

Why it matters for capital raisers: Cascade is an active LP in select private equity funds and maintains co-investment capacity. The office has historically favored managers with a value orientation and long holding periods. Real assets, infrastructure, and agriculture are key sectors of interest. Entry is relationship-driven.

4. Bezos Expeditions

Estimated AUM $235 billion+ Headquarters Mercer Island, Washington Wealth Creator Jeff Bezos (Amazon) Founded 2005 Type Single-Family Office Key People Melinda Lewison (Managing Director, since 2005); Jeff Bezos (Principal) Employees 150+ professionals Primary Sectors Venture capital, technology, AI, robotics, biotech, aerospace, media Altss Profile View on Altss

Bezos Expeditions manages the personal investments and philanthropic activities of Amazon founder Jeff Bezos. The office is one of the most active mega-family offices in venture capital globally, with a track record of 37 exits as of June 2025 — including 12 unicorns ($1B+ valuations), 12 IPOs, and 24 acquisitions. Approximately 70% of investments target technology sectors. The office publicly lists its portfolio companies on its website — an unusual level of transparency for a family office of this scale.

Bezos retains approximately 8-9% of Amazon shares, with the core holding valued at approximately $190 billion based on current market capitalization. After the 2019 divorce settlement, MacKenzie Scott manages her own wealth separately through Crosby Advisors (estimated ~$35B, listed at #22 below).

Venture and Growth Portfolio (Verified Investments):

Profluent Bio · Stage/Detail: Series B, $106M co-led (Nov 2025) · Sector: Biotech/AI — AI-designed proteins, OpenCRISPR-1 FieldAI · Stage/Detail: $405M round (Aug 2025) · Sector: Robotics/AI — general-purpose robotics intelligence Toloka · Stage/Detail: $72M round (May 2025) · Sector: AI data solutions, model training Perplexity AI · Stage/Detail: Series B, $73.6M (Jan 2024) · Sector: Generative AI search engine Figure AI · Stage/Detail: Growth round · Sector: AI/robotics Synchron · Stage/Detail: Series D, $200M · Sector: Neurotech Airbnb · Stage/Detail: Early rounds (pre-IPO) · Sector: Hospitality Uber · Stage/Detail: Series B, $37M (Oct 2011) · Sector: Mobility Workday · Stage/Detail: Pre-IPO (before 2012 IPO) · Sector: Enterprise SaaS ($50B+ market cap as of 2025) GRAIL · Stage/Detail: Co-founded 2016 · Sector: Non-invasive cancer screening, liquid biopsies Juno Therapeutics · Stage/Detail: Early · Sector: Cancer therapeutics Swiss Mile · Stage/Detail: $22M · Sector: AI robotics (Swiss startup) Twitter/X · Stage/Detail: Early · Sector: Social media Stack Overflow · Sector: Developer tools General Assembly · Sector: Education Business Insider · Sector: Media Nextdoor · Stage/Detail: Pre-SPAC (2021) · Sector: Community/social Zocdoc · Stage/Detail: Early · Sector: Health tech Labelbox · Sector: Enterprise data labeling / AI tools

Major Non-Venture Holdings:

Asset Detail Amazon ~8-9% stake. Executive Chairman Blue Origin $8B+ invested. 165,000-acre Corn Ranch in West Texas as primary launch base Washington Post Acquired 2013 for $250M; now valued at approximately $1.4B Bezos Earth Fund $10B pledge; ~$2B granted to date Real Estate $165M Warner Estate (purchased from David Geffen, 2020 — LA record). $80M Manhattan (3 apartments + penthouse, Madison Square Park, 2019). $79M Indian Creek Island villa, Miami (2024). Total RE holdings exceed $400M

Why it matters for capital raisers: Bezos Expeditions is actively deploying into seed through growth-stage venture, with particular interest in AI, robotics, climate tech, biotech, and frontier science. The office evaluates direct investments and has historically moved quickly on conviction-driven opportunities. The decision-making model is principal-led. Managed by Melinda Lewison, who has run the office since its founding.

5. Bayshore Global Management

Estimated AUM $239 billion (Bloomberg, April 2026) Headquarters Palo Alto, California, US; Singapore Wealth Creator Sergey Brin (Google/Alphabet) Founded 2005 Type Single-Family Office Key People Sergey Brin (Principal) Primary Sectors Public equities, private equity, real estate, ESG Altss Profile View on Altss

Bayshore Global Management was established following Google's 2004 IPO to manage the wealth of Sergey Brin and his then-wife Anne Wojcicki (23andMe CEO). The office maintains a deliberately low profile — among the least publicly visible of any top-10 family office. Reported allocations span public and private equity, real estate, and a significant ESG-focused portfolio.

Brin's personal interests in airship technology (through LTA Research, developing hybrid airships for humanitarian cargo delivery) and health-related ventures reflect in the office's investment thesis. Bayshore operates from both Palo Alto and Singapore, consistent with the broader trend of major tech-wealth offices establishing Asian presence. The SWFI estimates Bayshore's AUM at approximately $100 billion; other sources estimate higher based on Brin's current Alphabet stake and public market portfolio.

Why it matters for capital raisers: Low accessibility. Bayshore does not publicly solicit deal flow and operates through trusted intermediary networks. ESG-aligned managers with health or deep tech exposure have the highest probability of engagement, but cold outreach success rates are near zero.

Tier 2 — The $50B–$100B Offices

6. Mousse Partners (Wertheimer Family)

Estimated AUM $90–100 billion Headquarters Solow Building, New York City. Additional offices: Paris, Beijing, Hong Kong Wealth Creator Alain & Gérard Wertheimer (Chanel) Founded 1991 Type Single-Family Office — investment division of Mousse Investments Limited (formerly Litor Limited), Cayman Islands holding company for Chanel Key People Charles Heilbronn (Chairman); Suzi Kwon Cohen (CIO); Arthur Heilbronn (MD, Co-Head PE & Venture) Employees 36+ (Bloomberg) Primary Sectors Luxury, equities, private equity, venture, thoroughbred racing, wine Altss Profile View on Altss

Mousse Partners manages the wealth of the Wertheimer brothers, co-owners of Chanel — one of the last major luxury houses to remain entirely privately held, with an estimated enterprise value exceeding $100 billion. The combined Wertheimer fortune exceeds $100B (Caproasia, June 2024), with the brothers each exceeding $68B individually.

The office is run by Charles Heilbronn, half-brother of Alain and Gérard Wertheimer, who has led Mousse for over 20 years and also serves as a Chanel executive.

Key Personnel:

Charles Heilbronn · Role: Chairman · Background: Half-brother of Wertheimer brothers. Over 20 years leading Mousse Partners Arthur Heilbronn · Role: Managing Director, Co-Head of PE & Venture Direct Investing · Background: Age 38. 4th generation. UPenn (PPE, magna cum laude, 2008). Harvard MBA (2014). Goldman Sachs IB analyst (2008-2011) → GF Capital Management → Chanel (2018) → Mousse (2019). Board member Rothschild & Co. Identified as next Head of family office (Caproasia, September 2025) Suzi Kwon Cohen · Role: CIO (since 2016) · Background: Previously led North America PE for Singapore's GIC (sovereign wealth fund) David Yang · Role: Managing Director, Hong Kong · Background: Previously Head of China PE at Abu Dhabi Investment Authority (ADIA) for 5+ years. Also CVC Capital Partners, Warburg Pincus, McKinsey

Cash Flow Intelligence: Chanel dividends to Mousse Investments Limited totaled $12.4B over three years through 2023 — $1.6B (2019), $4.98B (2021), and $5.4B (2023 alone). This dividend flow gives Mousse Partners significant and recurring dry powder for deployment.

Investment Portfolio (Verified):

Investment Detail Rothschild & Co Stake acquired in 2023 private takeover. Alongside Rothschild family, Peugeot, Dassault families Rockefeller Capital Management Led recapitalization (October 2025). Valued firm at $6.6B. Alongside Progeny 3, Abrams Capital Ulta Beauty Held 14+ years, returned 1,700%+. Sold most of stake in 2021 (~$480M in share sales). Heilbronn was board director for 20+ years Beautycounter/Counter Increased stake (2021). Clean beauty brand Cava Funding round participant (fast casual restaurant chain) Coty Inc. Historical stake (cosmetics) Thoroughbred Racing One of the largest racehorse owners globally Bordeaux Vineyards Château Rauzan-Ségla, Château Canon

The office has recently hired former IB analysts from JPMorgan and Lazard, signaling an expansion of the direct investing team.

Why it matters for capital raisers: Mousse Partners engages selectively with external managers, favoring long-duration strategies with low public visibility. With $12.4B in Chanel dividends over three years and a 4th-generation leader positioned to take over, the office has both significant dry powder and a long-term investment horizon. Access is almost exclusively through established intermediary relationships. The family does not attend industry conferences or maintain a public presence in LP networks.

7. Ballmer Group

Estimated AUM $133 billion Headquarters Bellevue, Washington, US Wealth Creator Steve Ballmer (Microsoft) Founded 2014 Type Single-Family Office Primary Sectors Philanthropy, public equity, community development Altss Profile View on Altss

The Ballmer Group functions as both a family office and a philanthropic vehicle for Steve Ballmer, former CEO of Microsoft. Ballmer retains a significant Microsoft stake (approximately 4%, worth ~$133B at current market capitalization). The philanthropic arm focuses on economic mobility in the United States, with specific programs addressing children and families in poverty. The office also manages Ballmer's ownership of the Los Angeles Clippers (NBA), valued at approximately $4.6 billion. Ballmer personally funded USAFacts, a nonprofit data platform for government spending.

Why it matters for capital raisers: The Ballmer Group's external investment activity is primarily philanthropic and impact-oriented. Fund managers focused on economic mobility, workforce development, or affordable housing may find alignment. Traditional PE/VC fundraising approaches are unlikely to gain traction.

8. Waycrosse Inc. (Thomson Family)

Estimated AUM $65 billion Headquarters Toronto, Canada Wealth Creator Thomson Family (Thomson Reuters) Founded 1988 Type Single-Family Office Key People David Thomson (Chairman, Thomson Reuters) Primary Sectors Media, diversified equities, real estate, private equity Altss Profile View on Altss

Manages the investment portfolio of the Thomson family, which controls Thomson Reuters through The Woodbridge Company (listed separately at #10). David Thomson, the family patriarch, is consistently ranked as Canada's wealthiest individual with an estimated net worth exceeding $75 billion. The family maintains controlling interests in Thomson Reuters (69% via Woodbridge) and The Globe and Mail, alongside a diversified investment portfolio spanning real estate, private equity, and public equities.

Waycrosse operates as the active investment management arm, distinct from Woodbridge's holding company function.

Why it matters for capital raisers: The Thomson family is an active LP in Canadian and international PE funds. The office has a strong preference for managers with Canadian or North American focus. Media, data/information services, and financial technology align with the family's operating expertise.

9. Pontegadea Inversiones (Ortega Family)

Estimated AUM $55 billion (Pontegadea + Fedesa combined); total Ortega fortune: $122B (Bloomberg, April 2026) Headquarters A Coruña, Spain Wealth Creator Amancio Ortega (Inditex/Zara) Founded 1975 (Pontegadea Inversiones entity); 2001 (active investment arm) Type Family holding company with investment office Key People Amancio Ortega (Founder); Marta Ortega (Chairman, Inditex) Dividend Income $3.3B from Inditex for 2024; ~$400M+ annual rental income from RE portfolio RE Portfolio €34.3 billion (end 2024) — the largest private real estate portfolio in Europe Primary Sectors Real estate, public equities, infrastructure, renewable energy, logistics, parking infrastructure Altss Profile View on Altss

Pontegadea is one of the world's largest private real estate investors, funded primarily by Inditex dividends — Ortega retains approximately 59.29% of Inditex shares. Geographic allocation: 51% Europe, 46% Americas, 3% Asia. The investment philosophy centers on premium commercial real estate in global capitals — buying stabilized, rent-ready assets rather than development projects.

Non-Real Estate Investments:

• 9.99% stake in Telefónica's physical infrastructure (submarine cables, fiber optic networks, mobile antennas)
• 49% stake in PD Ports (UK ports and logistics) — acquired from Brookfield Asset Management (July 2025)
• Stake in Q-Park, a leading European parking infrastructure operator (December 2024)
• Five-star hotel acquisition near Opéra, Paris (~€200M, 2024) — the largest central Paris real estate transaction that year
• Growing renewable energy portfolio across Spain and Portugal, including wind and solar projects

Marta Ortega (daughter) assumed the chairmanship of Inditex in 2022, signaling generational transition. Fedesa SA is the family's older holding structure; Pontegadea is the primary active investment vehicle.

Why it matters for capital raisers: Pontegadea's external fund allocations are limited — the office strongly prefers direct investment in real assets. Fund managers with real estate, infrastructure, or renewable energy deal flow are the best fit. The office operates from A Coruña, not Madrid or London — a geographic detail that matters for relationship-building.

10. The Woodbridge Company (Thomson Family)

Estimated AUM $54 billion Headquarters Toronto, Canada Wealth Creator Thomson Family Founded 1978 Type Family holding company Primary Sectors Media, financial data, diversified investments Altss Profile View on Altss

The principal holding company of the Thomson family. Woodbridge holds a controlling 69% stake in Thomson Reuters (market capitalization approximately $85 billion). Often listed alongside Waycrosse as part of the Thomson family's broader investment architecture. Woodbridge functions primarily as a holding entity rather than an active allocation office — that role falls to Waycrosse.

Selected Tier 3 Deep Profiles:

DFO Management / MSD Capital (#12) — Michael Dell. Dell's family office manages $50B+ in estimated assets. Net worth: $151B (Bloomberg, 2025). The office restructured from MSD Capital to DFO Management in December 2022 and operates from New York City, Santa Monica, and West Palm Beach with 50-100 employees.

CEO Gregg Lemkau joined in 2021 after 28 years at Goldman Sachs, where his last role was Head of Global Investment Banking. Co-Founder John C. Phelan serves as Chairman Emeritus (retired as CIO June 2022). Co-Founder Glenn R. Fuhrman retired at the end of 2019. Chief Legal Officer Marc Lisker has served since 1999 (previously Mayer Brown LLP).

Dell's investment philosophy is captured in his own words: "I already got the get rich part, so I'm focused on staying rich." Capital protection comes first, compounded returns second. The office deploys across four strategies: Credit (structurally protected, targeting 9-13% returns across private credit, leveraged loans, and RE credit); Real Estate (~$2.5B equity committed into 35+ transactions since 2004, including Four Seasons Maui, Four Seasons Big Island Hawaii, Fairmont Miramar, and The Boca Raton acquired for $875M in 2019); Private Capital (control buyouts and structured equity in companies including East West Manufacturing, West Monroe Partners, Owl Rock Capital Corp, UFC, WIRB-Copernicus, Hayward Industries, and Ring Container Technologies); and Growth Equity (new strategy built out in 2024-2025 — Lemkau described it as "a little bit crazy that Michael Dell's family office didn't have this before").

13F (Q2 2025): 3 equity positions totaling $155M — Townsquare Media, Hayward Holdings, Safehold Inc.

The third-party arm, MSD Partners, merged with BDT & Company (Byron Trott's merchant bank) in January 2023 to form BDT & MSD Partners, which has deployed $50B+ across strategies since 2010. Notable deals include the $24B Dell Inc. privatization (2013, with Silver Lake), the $60B Dell-EMC merger (2016), Dell's 2018 re-IPO, and the Grand Central Terminal air rights transaction (bought $126M, sold portions to JPMorgan for $238M in 2016-2018).

Dell's philanthropy: Michael & Susan Dell Foundation (1999), focused on urban poverty in the US, India, and South Africa. In December 2025, Dell announced a $6.25B donation to children's investment accounts.

ICONIQ Capital (#14). The largest technology-focused multi-family office in the world, managing $80B+ in total assets ($71B discretionary per 2025 regulatory filings). Founded in December 2011 and headquartered at 300 Mission St, San Francisco, with additional offices in Palo Alto, New York, London, and Singapore.

Founders: Divesh Makan (South African; University of Natal → Wharton MBA → Goldman Sachs SF → Morgan Stanley → met Zuckerberg shortly after Facebook moved to SF); Michael Anders (previously Goldman Sachs, Morgan Stanley); Chad Boeding (previously Goldman Sachs, Morgan Stanley).

Known Clients: Mark Zuckerberg, Jack Dorsey, Reid Hoffman, Dustin Moskovitz, Sheryl Sandberg, Chamath Palihapitiya, James Murdoch, J.J. Abrams, Adam D'Angelo (Quora).

Investment Programs: Growth Equity ($5.75B fund closed 2024); IPI Partners (subsidiary — acquiring, developing, and operating digital infrastructure / data centers); Core Private Equity; Venture Capital.

Landmark Investments: Led Anthropic's $13B Series F round (2025) — the largest single investment in the firm's history. Early-stage investments in Snowflake, Figma (backed since seed round, 2013), Alibaba (pre-IPO), Flipkart (pre-IPO), Uber, Sprinklr, and Drata.

Corporate Structure: Blue Owl Capital acquired a 6% stake in 2020. The firm maintains a hybrid model separating advisory/wealth management from the investment arm to prevent conflicts. CPP Investment Board (Canadian pension) is an institutional client. ICONIQ is closed to new advisory clients. In September 2024, the firm began exploring new exit strategies including M&A and secondary markets amid the IPO drought.

Soros Fund Management (#15). Converted from a hedge fund to a family office in 2011 when George Soros returned approximately $1 billion to outside investors. Manages approximately $25B in combined family and philanthropic assets from New York City.

CEO and CIO Dawn Fitzpatrick has led the firm since 2017 — the first woman to hold the position. Background: 25 years at UBS (Head of Investments for UBS Asset Management overseeing $500B+, CEO/CIO of UBS O'Connor hedge fund). Wharton BSc Economics. Began career as a clerk on the American Stock Exchange, then trader on the Chicago Board of Options. Current external roles: Non-executive director of Barclays plc, board member of Under Armour (appointed April 2025), Chair of the Federal Reserve Bank of Dallas Financial Sector Advisory Council, Bretton Woods Committee Advisory Council, and Bloomberg New Economy Advisory Board.

Alexander Soros chairs the Open Society Foundations — the public and philanthropic face. He does not oversee daily investment operations. George Soros, now in his 90s, is no longer a functioning part of the firm's business.

Under Fitzpatrick, the firm shifted from speculative macro bets to a balanced multi-asset approach spanning equities, fixed-income, venture capital, and private equity. The strategy favors data-driven quantitative models over star portfolio managers, with reduced leverage and a bias toward stable assets. Focus areas include clean energy, technology, and healthcare innovation. At Bloomberg Invest in March 2025, Fitzpatrick warned that private market investors are in a "world of hurt" compared to public equity returns. At the Barclays Forum in 2025, she stated: "Let volatility be your friend when you have conviction."

Altss data indicates typical investments of $10M-$150M targeting technology, financial services, data, energy, and retail. The firm participates in multiple funding rounds and conducts all due diligence in-house.

Emerson Collective (#17). Laurene Powell Jobs's organization operates at the intersection of investing, philanthropy, advocacy, and media. Net worth: $11.9B (Bloomberg, July 2025, ranked 244th). The Waverley Street Foundation holds $1.8B+ in assets with 184 employees, plus an additional $3.5B committed to climate over 10 years (2021).

Emerson Collective is structured as an LLC rather than a traditional foundation or fund — a deliberate choice allowing maximum flexibility. The entity can deploy grants, political advocacy, or investments depending on what is most effective. The organization maintains a deliberately low profile.

Fingerboard Family Office (#23). The Newhouse family's office, connected to the Advance Publications media empire (Condé Nast, Reddit, Discovery). The office operates an endowment-style portfolio primarily investing via funds, with a globally diversified allocation managed by CIO Bei Saville. Fingerboard is an active LP across PE, VC, and hedge fund strategies.

Selected Tier 4 Profiles:

Willett Advisors (#31). Michael Bloomberg's family office manages his personal wealth (distinct from Bloomberg LP, which generates the income). The office allocates across public equities, fixed income, real estate, and alternatives. Bloomberg's philanthropic commitments through Bloomberg Philanthropies (climate, public health, gun safety, education) are substantial — the foundation has given away over $17 billion, making Bloomberg one of the largest living donors globally.

Agache / Arnault Family Office (#33). Bernard Arnault, Chairman of LVMH and one of the world's wealthiest individuals, manages personal investments through Agache and related entities. The family's wealth is primarily concentrated in LVMH shares (Arnault family holds approximately 48.6% of the luxury conglomerate). Investment activity outside LVMH includes strategic stakes in luxury and technology companies, real estate, and select PE investments. Generational transition is underway — all five of Arnault's children hold positions within LVMH brands.

Vulcan Capital (#35). The investment arm of the late Paul Allen's estate, Vulcan Capital continues to manage a diversified portfolio spanning technology, life sciences, real estate, and media. Allen's estate has maintained the investment platform despite his 2018 passing, with Jody Allen (sister) overseeing the family's interests. Notable holdings include the Portland Trail Blazers (NBA), the Seattle Seahawks (NFL — sold in 2024), and significant real estate in Seattle's South Lake Union neighborhood.

Pritzker Group (#41). The Pritzker family (Hyatt Hotels, TransUnion, Marmon Group) operates one of the most institutionalized family investment platforms in the US. The Pritzker Group encompasses private equity, venture capital, and asset management arms. The family's estimated combined wealth exceeds $30 billion, but investable family office assets under active management are estimated at approximately $10 billion. The office is a known LP in mid-market PE funds and has a strong direct investment track record.

Regional Breakdown: Where the Largest Family Offices Are Based

Region: North America · Count (Top 50): 28 · Combined Est. AUM: ~$1.55T · Key Hubs: New York (10), Seattle/PNW (4), San Francisco (3), Bentonville (3), Chicago (2) Region: Europe · Count (Top 50): 13 · Combined Est. AUM: ~$350B · Key Hubs: London (4), Paris (2), Copenhagen (2), Hamburg, Duisburg, A Coruña, Leiden, Billund Region: Asia-Pacific · Count (Top 50): 6 · Combined Est. AUM: ~$85B · Key Hubs: Hong Kong (2), Singapore, Jakarta, Bangkok Region: Middle East · Count (Top 50): 3 · Combined Est. AUM: ~$60B · Key Hubs: Dubai, Riyadh, Jeddah

North America dominates, driven by the concentration of technology wealth on the West Coast and financial services wealth in New York. The US alone accounts for 24 of the top 50. Bentonville, Arkansas — population 57,000 — hosts three entries (Walton Enterprises, Builders Vision, RZC Investments), making it the most over-indexed city per capita for family office concentration in the world. Altss data shows US family offices now allocate 86% of portfolios to North America — a multi-year rise from 74% in 2020.

Europe's representation is heavily weighted toward family-controlled industrial holding companies (Würth, Haniel, KIRKBI) and luxury empires (Chanel, LVMH, Grosvenor). London is the operational hub even for families whose wealth originates elsewhere — INEOS (originally Manchester-based), Esas Holding (Turkish-origin), and XT Group (Israeli-origin) all base their family office operations in London. Western Europe accounts for 26% of global family office asset allocation, though Western European family offices have reduced their home-based assets by more than 10%.

Asia-Pacific is underrepresented in AUM terms within the top 50, but is the fastest-growing region by count. Singapore alone hosts 1,400+ registered family offices as of end-2023, the vast majority below the $10B threshold. MAS reduced Section 13O/13U application processing times from 12 months to approximately 3 months in mid-2025, accelerating formation further. The region's largest offices (Hartono, Blue Pool, CP Group) reflect the maturation of first-generation tech and industrial wealth. Asia-Pacific (excluding Greater China) remains the top region where family offices plan to increase investments over the next five years.

The Middle East is experiencing rapid family office formation driven by diversification away from hydrocarbon wealth. Dubai, Abu Dhabi (via ADGM), and Riyadh are competing aggressively for family office headquarters through favorable tax regimes, residency programs, and regulatory frameworks. Interest in Middle East investment among global family offices jumped from 5% in 2024 to 13% in 2025 — the largest year-over-year shift for any region. Only 28% of family offices report no plans to invest in the region, down from 40% the prior year.

What the Top 50 Are Investing In (2025–2026)

Based on deal activity tracked across the Altss platform and verified institutional survey data:

Private equity — 27% average allocation across the top 50. The dominant allocation. Larger offices increasingly bypass fund structures in favor of direct deals and co-investments. DFO Management, Bessemer Investors, and Koch Disruptive Technologies operate essentially as PE firms. Since 2015, the share of direct investments has grown from 44% to 70% of all family office transactions. Altss data shows over half of family offices have been disappointed with their VC returns, but a majority still expect PE and VC to outperform over the next 12 months. Private equity allocations slipped from 22% to 21% in 2024, with offices planning to reduce to 18% in 2025 — driven by slow exits, subdued capital markets, and expensive financing.

Public equities — 22%, and rising. Still significant and now gaining share. Many offices maintain concentrated founder stakes (Walton/Walmart, Arnault/LVMH, Dell/Dell Technologies, Ballmer/Microsoft) alongside diversified public market allocations managed by external sub-advisors. Developed market equity allocations rose to 26% in 2024, with offices planning 29% for 2025. Nearly half (46%) expect significant or moderate increases over five years. The attraction is access to transformational themes — AI, healthcare, longevity, and energy transition — with the added benefit of liquidity and legal clarity that private markets cannot match.

Real estate — 18%. Pontegadea (Ortega) and Grosvenor Estate are the global leaders. Trophy commercial assets in gateway cities remain the preferred vehicle, though logistics, data centers, and multifamily have gained share. Several offices have increased real estate exposure as a hedge against inflation and currency volatility. Pontegadea alone deployed over $1.3B in US real estate acquisitions during 2025.

Venture capital — 12%. Bezos Expeditions, Emerson Collective, and Koch Disruptive Technologies are the most active. AI, climate tech, biotech, and defense tech are the dominant themes in 2025-2026. Over 80% of family offices expect to invest in AI within the next 2-3 years, particularly for applications in financial reporting and data analysis. Smaller offices (outside the top 50) are more likely to access venture through fund-of-funds or emerging manager programs.

Hedge funds — 8%. Family offices have the highest hedge fund allocation of any institutional investor type, across offices Altss tracks. Trade war is perceived as the most significant investment threat for 2025 — in response, 40% of family offices rely more on manager selection and active management, 31% increased hedge fund allocations, and 27% increased illiquid asset holdings as portfolio protection.

Private credit — 6%, and the fastest-growing allocation. Private debt allocations doubled from 2% to 4% year-over-year in 2024, with plans to increase to 5% in 2025. Across offices Altss tracks, 32% of family offices plan to increase private credit allocations — the highest figure for any alternative asset class. Within private credit, family offices show a clear preference for special situations/opportunistic strategies and direct lending. MSD Partners, through its credit arm, is among the most active family office-affiliated direct lenders.

Infrastructure and real assets — 5%, with strong momentum. Altss data shows 30% of family offices plan to increase infrastructure allocations, with 75% expressing positive sentiment on the asset class. Family offices are attracted to infrastructure's stable cash flows, portfolio diversification properties, and perceived resilience. The G20 estimates $94 trillion in global infrastructure investment is required by 2040, creating a $15 trillion funding gap. Pontegadea's recent acquisition of a 49% stake in PD Ports and the Walton family's clean energy commitments through Builders Vision are representative.

Gold and precious metals — used by 19% globally. Usage has grown more than any other asset class compared to the previous year. 21% of family offices anticipate a significant or moderate increase in gold allocation over the next five years. This serves as a direct hedge against trade war and geopolitical risk.

Digital assets — ~2% of portfolios. Allocations remain small in percentage terms among the top 50. Blue Pool Capital (Tsai/Ma) and several Singapore-based offices are the most active. Only 16% of family offices have a clear investment strategy that includes blockchain and/or DeFi.

Family Office Allocation Trends: What the Data Shows

Altss aggregates allocation data, deal activity, and sentiment signals across the 9,000+ family offices on our platform. Combined with the most comprehensive institutional surveys available — covering 500+ single family offices with $320B+ in collective AUM — the following patterns define the family office landscape entering 2026.

Risk Landscape and Sentiment

A global trade war has displaced geopolitical conflict as the number one concern for family offices. Geopolitical uncertainty remains the most important issue for 84% of offices and is a critical factor in capital allocation decisions. Overall sentiment has turned negative for the first time since 2020, with 60% of family offices pessimistic about the global outlook — a stance expected to continue through 2026 as tariffs, policy shifts, and market fragmentation weigh on confidence.

Asset Allocation Shifts

Asset Class — 2023 Allocation · 2024 Allocation · Planned 2025 (Among Those Changing) Developed Market Equities — 24% · 26% · 29% Private Equity — 22% · 21% · 18% Private Debt — 2% · 4% · 5% Cash — 10% · 8% · Declining Fixed Income — — · — · Increasing

Regional Allocation: 53% North America, 26% Western Europe — nearly 80% of all assets. US offices: 86% to North America (up from 74% in 2020). Allocations to Asia-Pacific (excluding Greater China) and Greater China fell to 7% each. India and Mainland China are the most likely markets for increased exposure over the next 12 months.

Emerging Technology: 80%+ expect to invest in AI within 2-3 years. Family offices are most keen to invest in healthcare/medicine, electrification, and AI. Only 16% have a clear blockchain/DeFi investment strategy.

Succession Planning: 53% of family offices have wealth succession plans in place (up from 47% the prior year). However, 29% of those without plans believe they have "plenty of time" — complacency that could carry long-term costs.

Hedging Strategies: Active management (40%), hedge funds (31%), illiquid assets (27%). Precious metals used by 19% globally, with 21% anticipating increases over five years.

Governance: 61% have an investment committee, averaging three non-family members. Only 35% intend to make changes to their asset allocation in 2025.

Hiring: 73% of family offices prioritize personality fit over education or qualifications when hiring. 72% highlighted a candidate's trustworthiness. Most have fewer than 5 employees; 19% have 20+; average team size is 12.

Alternatives and Sentiment

Alternative allocations now represent 42% of family office portfolios — up from 39% in 2022-2023. Private credit (32% plan to increase) and infrastructure (30% plan to increase) are the most-favored alternative assets. Infrastructure investment is driven by an estimated $15 trillion funding gap on $94 trillion in required global infrastructure investment by 2040.

Overall sentiment among family offices turned negative for the first time since 2020. 60% are pessimistic about the global outlook — a stance shaped by geopolitical uncertainty, new tariff regimes, and market fragmentation. Three structural trends are identified as most likely to drive equity markets in the next decade: artificial intelligence, power and resources, and longevity.

How Family Offices Differ From Institutional LPs

For fund managers and capital raisers, understanding how these offices behave differently from pensions, endowments, and sovereign wealth funds is critical for both targeting and process design.

Decision speed. A pension fund might take 6-18 months from first meeting to capital commitment. The largest family offices can move in weeks when conviction is high. DFO Management and Bezos Expeditions are known for rapid diligence cycles. This speed advantage comes from principal-led decision making — fewer committees, fewer gatekeepers, faster iteration.

Ticket size flexibility. The top 50 routinely write checks from $5M seed rounds to $500M+ co-investments. There is no minimum mandate size constraint the way a CalPERS or Ontario Teachers' might have.

No consultants. Unlike institutional allocators, family offices rarely use investment consultants (Cambridge Associates, Mercer, Aksia) as gatekeepers. Access is typically through direct relationships, warm introductions, or event-driven networking. The absence of consultant intermediation means the pitch process is shorter, but the bar for trust is higher.

Longer hold periods. Family offices are not constrained by fund life or vintage year considerations. Patient capital with 10-20+ year horizons is available, particularly from European industrial families (Haniel, Würth, KIRKBI) and Middle Eastern offices.

Concentrated bets. Many offices are comfortable with portfolio concentration that would violate institutional diversification mandates. This is both an opportunity and a risk for managers — a single family office can anchor an entire fund, but their due diligence is idiosyncratic and relationship-driven.

Co-investment culture. Over two-thirds of family office deals are done alongside other family offices. This creates network effects — one family office commitment often unlocks others through informal referral channels.

No public reporting. Family offices have no obligation to disclose allocations, returns, or manager relationships. This makes intelligence gathering harder — and makes platforms like Altss that track family office activity through verified signals more valuable than those relying on self-reported data.

How to Approach the Largest Family Offices for Fundraising

Based on Altss data across 9,000+ family offices and feedback from capital raisers using the platform:

1. Identify the actual decision-maker. In principal-led offices, the principal decides. In professionalized offices, the CIO or investment committee controls allocation. Getting this wrong wastes months. Altss profiles map the decision authority structure for each office.

2. Confirm mandate fit before outreach. The investment mandate is the primary gate. Pitching a VC fund to a family office that only allocates to real estate generates noise, not meetings. Altss tracks current mandates, sector focus, ticket size ranges, and geographic preferences for each office.

3. Time outreach to activity signals. A new CIO appointment, a conference attendance, a new fund commitment — these are the moments when a family office is actively evaluating managers. Cold outreach at random has a near-zero success rate. Signal-driven outreach has a meaningfully higher conversion rate.

4. Lead with data, not narrative. The largest offices see hundreds of inbound pitches per year. What cuts through is specificity: verified AUM, named investments, evidence of mandate fit. Not "we're a differentiated platform" — that phrase appears in every pitch deck.

5. Respect privacy. Family offices value discretion above almost everything else. Mentioning a family office by name in marketing materials, press releases, or conference presentations without explicit permission is a relationship-ending move.

Frequently Asked Questions

Walton Enterprises LLC, managing approximately $225 billion for the descendants of Walmart founder Sam Walton, is the largest family office by assets under management. The family operates a hub-and-spoke model with WEI as the central vehicle, WIT LLC as the investment arm (since 2020), and satellite offices including Builders Vision, Madrone Capital Partners, Zoma Capital, and RZC Investments. If ranked by total family net worth rather than family office AUM, Excession LLC (Elon Musk) would claim the top position with a net worth of $630B (Bloomberg, April 2026) to $803B (Forbes) — but much of that wealth is held in the combined SpaceX-xAI entity (merged February 2026, valued at $1.25 trillion) rather than managed through a traditional family office structure.

How many family offices are there in the world? Estimates range from 8,000 to 20,000 depending on how "family office" is defined. Industry data shows approximately 4,500 in 2023 (up from ~1,285 in 2019 — a tripling in four years), with the global count now exceeding 8,000 and growing at approximately 4.8% annually. Altss tracks 9,000+ verified family offices globally, including offices that are too small or too private to appear in legacy databases. Total global family office AUM is estimated at $5-10 trillion.

What do the largest family offices invest in? Private equity is the dominant allocation (27% average across the top 50), followed by public equities (22%), real estate (18%), venture capital (12%), hedge funds (8%), and private credit (6%). The trend since 2015 is a decisive shift from fund allocations toward direct investments and co-investments. The fastest-growing allocation is private credit, which doubled from 2% to 4% in 2024. Infrastructure is gaining strong momentum, with 30% of family offices planning to increase allocations.

How much money do the top 50 family offices manage? The 50 largest family offices collectively manage approximately $2.4 trillion in assets under management, roughly equivalent to the GDP of France. The top 10 alone account for over $1.5 trillion.

What is the difference between a single-family office and a multi-family office? A single-family office (SFO) manages wealth for one family. A multi-family office (MFO) manages wealth for multiple unrelated families, often providing shared infrastructure, pooled investment vehicles, and economies of scale. Of the top 50, 32 are SFOs. ICONIQ Capital (#14) is the most prominent MFO on the list, managing $80B+ for technology founders including Mark Zuckerberg, Jack Dorsey, and Reid Hoffman.

What is the difference between a family office and a hedge fund? A family office manages wealth for a single family or small group of families with no external investors. A hedge fund manages pooled capital from multiple external investors. Family offices have longer time horizons, no redemption pressures, no management fee/carry economics to external LPs, and more flexible investment mandates. Several offices on this list converted from hedge funds — notably Soros Fund Management (#15), which returned outside capital in 2011 and now operates under CEO/CIO Dawn Fitzpatrick with a balanced multi-asset approach.

What is the biggest risk family offices face in 2025-2026? A global trade war ranked as the number one investment risk for family offices in 2025-2026, overtaking geopolitical conflict. Across offices Altss monitors, 84% cite geopolitical uncertainty as the most important issue, with overall sentiment turning negative for the first time since 2020. Family offices are responding with increased allocation to developed market equities, gold, and hedge funds as hedging strategies.

How do I find family offices that invest in my fund's strategy? Altss provides searchable profiles for 9,000+ family offices, including verified investment mandates, sector preferences, decision-maker contacts, and real-time activity signals. Capital raisers can filter by asset class, geography, ticket size, and office type to build targeted outreach lists.

Where are the fastest-growing family office hubs? Singapore (1,400+ offices as of end-2023, accelerating with streamlined MAS processing), Dubai / Abu Dhabi (ADGM and DIFC licensing), and Miami (growing cluster of LATAM-origin offices). Regionally, the Middle East and Africa are projected to post the highest family office sector growth at 8.17% CAGR through 2031. Interest in Middle East investment among global family offices jumped from 5% to 13% year-over-year.

What are family offices looking for in fund managers? Across the offices Altss tracks, family offices prioritize personality fit (73%) and trustworthiness (72%) over education or qualifications when evaluating relationships. Over two-thirds of deals are done alongside other family offices, making warm introductions and referral networks critical. Most family offices conduct all due diligence in-house without investment consultants.

AUM estimates are based on the most recent publicly available data as of April 2026. For offices with concentrated public equity positions (e.g., Walton/Walmart, Musk/Tesla, Ballmer/Microsoft), AUM is calculated using share prices as of March 31, 2026. Private asset valuations use the most recent funding round or third-party appraisal.

Ranking criteria prioritize estimated AUM of the family office entity. Where a family operates multiple vehicles (e.g., Thomson family's Waycrosse and Woodbridge), each is listed separately if independently managed. Sovereign-adjacent offices (e.g., Dubai Holding) are included only where the entity functions primarily as a family office rather than a sovereign investment vehicle.

Exclusions: We exclude multi-family offices that primarily serve external clients (e.g., Bessemer Trust in its non-Phipps capacity, Rockefeller Capital Management) unless the founding family retains a dominant share of AUM. We also exclude family-controlled public companies (Berkshire Hathaway, Samsung) that are not structured as family offices.

This ranking is updated quarterly. The full dataset — including 9,000+ family offices with verified contacts, investment mandates, and real-time activity signals — is available through the Altss platform.
