MARKET ANALYSIS
The Global OCIO Provider Landscape
Global OCIO assets: $4.8T as of late 2024. U.S. market: $2.5T in 2025, representing 75% of global assets and growing at 16% annually. The growth rate has been remarkably consistent, this is structural adoption, not cyclical.
Concentration is extreme. The top 14 firms each manage $100B+ and collectively control $3.47T, 71% of industry assets. Mercer leads at $670B, followed by Goldman Sachs at $450B, BlackRock at $400B, and Russell at $355B. Smaller OCIOs compete on specialization and service quality, but the scale advantage in manager access is real.
Consolidation is accelerating. Mercer absorbed Vanguard's OCIO unit. Hightower took a majority stake in NEPC. Cerity Partners merged with Agility and Verus. Pathstone combined with Hall Capital. Scale drives manager access, operational leverage, and the ability to offer competitive fee structures, expect more deals.
Pensions account for two-thirds of OCIO assets: corporate DB plans, DC plans, and public retirement systems. The remaining third is nonprofits, endowments, foundations, healthcare systems. The nonprofit segment is growing fastest as boards confront portfolio complexity they cannot manage internally.
