The Largest Asset Managers in the World

The three firms at the top run fundamentally different businesses, and each is now reshaping how private markets reach ordinary investors.

BlackRock is the world's largest asset manager, built on the iShares ETF franchise and the Aladdin risk-and-data platform. It ended 2025 at $14.04 trillion after a record $698 billion of net inflows, per its Q4 2025 results. The defining story is its pivot into private markets. BlackRock closed its $12.5 billion purchase of Global Infrastructure Partners in October 2024, its roughly $12 billion acquisition of private-credit manager HPS Investment Partners in July 2025, and its 2.5 billion pound (about $3.2 billion) purchase of data provider Preqin in March 2025, per company releases. The three deals, about $28 billion in all, gave BlackRock a top-five alternatives platform with over $675 billion in client assets and folded Preqin's data on 400,000-plus funds and companies into Aladdin. The logic sits in the economics: alternatives were 3% of BlackRock's long-term assets in 2025 but 17% of its base fees.

Vanguard is the index-fund pioneer and the price-setter for the whole industry. It managed about $11.6 trillion as of September 2025, second only to BlackRock, on a structure owned by its own funds that lets it run close to cost. In February 2025 Vanguard cut expense ratios on 168 share classes across 87 funds, its largest reduction in nearly 50 years, an estimated $350 million of savings for investors in that year alone, per Vanguard. The same month, Vanguard's S&P 500 ETF (VOO) passed State Street's SPY to become the world's largest ETF. Even Vanguard is edging into private assets: in April 2025 it agreed to build combined public-and-private portfolios with Blackstone and Wellington Management, starting with an interval fund.

Fidelity Investments is the largest privately held firm in the group, controlled by the Johnson family. Its managed assets reached $7.1 trillion in 2025, up from $5.9 trillion a year earlier, and it administers roughly $18 trillion in total client assets across brokerage, retirement, and custody, per Fidelity's 2025 annual report. That administration business, with tens of millions of retail accounts and a dominant 401(k) recordkeeping franchise, is the real moat: it is the pipe through which alternatives are now being pushed toward individual investors. Fidelity runs active and index funds, a fast-growing ETF lineup, and its own private-markets and digital-asset products.

Below the top three sit the ETF- and bank-affiliated managers, each pulling a different lever into private markets and the wealth channel.

State Street Investment Management, renamed from State Street Global Advisors in June 2025, reached a record $5.7 trillion in assets in 2025, a third straight year of 3%-plus organic growth, per State Street. It is the third-largest ETF issuer, with about $1.8 trillion across roughly 175 US products, and it created the category: its SPDR S&P 500 ETF (SPY), launched in 1993 as the first US-listed ETF, still holds around $700 billion. State Street's boldest move is putting private assets in an ETF wrapper. In February 2025 it launched the SPDR SSGA Apollo IG Public and Private Credit ETF (PRIV) with Apollo Global Management, the first ETF to hold private credit directly. Uptake has been modest, near $96 million by late 2025, and the SEC flagged liquidity and valuation concerns at launch, a reminder that daily-traded private credit is still an unsettled idea.

J.P. Morgan Asset Management, the asset-management arm of JPMorgan Chase, managed about $4.1 trillion as of December 2025. It is the largest issuer of active ETFs in the world, a business it effectively defined: its JPMorgan Equity Premium Income ETF (JEPI) holds more than $40 billion on its own, and the firm has extended the income-and-derivative model across a wide bench of funds. J.P. Morgan pairs that with a deep alternatives platform in private credit, real estate, and infrastructure, and the distribution reach of the largest US bank sitting behind it.

Goldman Sachs Asset Management reported a record $3.6 trillion in assets under supervision as of December 2025. Its edge is alternatives. Goldman raised a record $115 billion for private strategies in 2025 and collected a record $2.37 billion in alternatives management fees, per Goldman's 2025 reporting. It runs over $500 billion in private equity, private credit, real estate, and infrastructure, and has told investors it aims to reach $750 billion in fee-paying alternatives by 2030. Goldman is at once a manager of client money and one of the largest private-markets fundraisers in the world, which makes it a competitor to the GPs it also backs.

The firms in this ranking make money two ways: fees on the assets they manage, and, increasingly, the higher fees and carried interest that private strategies earn. A passive S&P 500 fund might charge three basis points; a private-credit or infrastructure fund charges ten to twenty times that, plus a share of profits. That gap explains almost every acquisition on this page.

Structurally they fall into camps. Index and ETF houses (BlackRock, Vanguard, State Street) run enormous low-fee franchises where scale is the moat. Active managers (Capital Group, PIMCO, T. Rowe Price, Wellington Management) compete on performance and specialization, in equities, fixed income, or specific strategies. Bank-affiliated managers (J.P. Morgan, Goldman Sachs, UBS Asset Management) span both and add wealth and institutional distribution. The convergence point is private markets, where all of them are now building or buying.

At this scale the managers are also allocators. BlackRock now owns two of the larger private-markets managers in the world in Global Infrastructure Partners and HPS; Goldman Sachs runs over $500 billion in alternatives; and the group as a whole seeds, commits to, and co-invests alongside private funds. A single mandate or fund commitment from one of these firms can anchor a raise, which places them among the most consequential limited partners (LPs) in the market.

Their real leverage, though, is distribution. Fidelity's recordkeeping, J.P. Morgan's and Goldman's wealth networks, and BlackRock's advisor model portfolios are the channels through which private assets now reach individuals. The 2025 executive order opening 401(k) plans to alternatives, and the model-portfolio and interval-fund launches, all run through those same pipes. Whoever owns distribution to the wealth and retirement channel captures the next decade of private-markets fees.

For a GP raising a fund, these firms are the competition and, sometimes, the buyer. They gather retail and institutional capital at a scale no independent manager can match, and they increasingly acquire successful GPs outright, as BlackRock did with Global Infrastructure Partners and HPS. A first-time manager is chasing the same wealth-channel and institutional dollars these platforms are aggregating, often against a house-brand product sitting on the same advisor's shelf.

They are also potential limited partners and partners. BlackRock, Goldman Sachs, J.P. Morgan, and the rest commit to and co-invest alongside private funds, seed new strategies, and buy minority GP stakes. Reaching the right desk, whether private credit, infrastructure, or secondaries, means knowing who runs that strategy and what the firm is currently backing, not cold-calling a general line. At firms this large, the distance between the front door and the decision-maker is the whole problem.

Altss maps asset managers and their private-markets arms within its coverage of 30,000+ institutional investors, RIAs, and family offices, and 9,000+ family offices globally. It tracks each firm's investment teams, mandates, and publicly observable activity, with verified decision-makers refreshed on a sub-30-day cycle, in-platform. Company coverage is live across 35M+ private-markets companies.

The data shortens the research, not the relationship. Altss is in-platform only, with no bulk export and no CRM or API delivery. It identifies who leads infrastructure or private credit at a firm like BlackRock or Goldman Sachs, and what those desks are publicly backing, so outreach lands on the right person rather than a general inbox.
