Family offices in Chicago
Chicago concentrates multi-generational industrial, finance, and agricultural wealth. The ecosystem has been reshaped by corporate HQ moves — most visibly Citadel's 2022 relocation to Miami — and by broader Midwestern wealth migration to Florida, though Chicago retains structural lead in commodity trading wealth and Midwestern industrial family offices.

Why Chicago concentrates family wealth
Chicago's ecosystem reflects the city's history as the commercial capital of the American Midwest — industrial manufacturing, agricultural processing, commodities trading (CME, CBOT heritage), railroads, and finance. Multi-generational fortunes (Pritzker, Crown, Reyes, Duchossois) anchor the ecosystem, with newer wealth from hedge funds, proprietary trading firms, and logistics layering on top.
Migration patterns matter. Significant Chicago-based wealth has established secondary offices in Miami, Palm Beach, and Naples; Ken Griffin's 2022 relocation of Citadel and Citadel Securities to Miami signaled a broader pattern that has continued through 2025 (Griffin completed his Chicago real estate exit in late 2025). Altss tracks Chicago-anchored-but-Florida-operating structures explicitly.

What this means for capital raisers
Chicago is an institutional-grade FO market with patient, multi-fund allocation cadence. Legacy industrial family offices operate through established CIO structures with formal DDQs, consultant oversight, and investment committee cycles that resemble institutional LP processes.
Sector fit skews industrial, infrastructure, real assets, and agricultural. Chicago commodity-trading-origin wealth is overweight natural resources, shipping, and physical-world businesses. Tech and software strategies have a harder raise than in NY, SF, or Boston.
Warm-intro paths: senior law firms (Kirkland, Sidley, Jenner & Block), Midwestern PE firms the family has backed, private banks (Northern Trust is particularly dominant in Chicago), and placement agents with Midwestern industrial relationships.
