Investment Strategy
The Bill & Melinda Gates Foundation is the largest private foundation in the United States by endowment size, with approximately $75 billion in trust assets as of mid-2024. Founded in 2000 by Bill Gates and Melinda French Gates, the foundation is headquartered in Seattle and focuses its grantmaking on global health, global development, education, and U.S. poverty reduction. Annual grantmaking has exceeded $7 billion in recent years, making the Gates Foundation the largest private grantmaker in the world.
The foundation’s endowment is held and managed by the Bill & Melinda Gates Foundation Trust, a separate legal entity from the foundation itself. The trust’s investment portfolio has historically been concentrated in public equities, with Berkshire Hathaway representing a major holding due to Warren Buffett’s ongoing charitable pledges to the foundation. The trust also invests across diversified global equities, fixed income, and a growing allocation to private markets including private equity and venture capital.
The trust’s investment approach differs from most large foundation endowments in its degree of concentration. While many peer institutions maintain diversified portfolios with significant alternatives allocations, the Gates Foundation Trust has historically held a smaller number of large positions. This reflects the unique circumstances of the endowment’s funding sources and the trust’s investment philosophy.
Private Markets Approach
The Gates Foundation Trust’s private markets program, while modest relative to the overall endowment size, still represents a substantial pool of capital in absolute terms. The trust commits to private equity, venture capital, and growth equity strategies, with a focus on managers and sectors that can deliver strong risk-adjusted returns at scale.
Given the trust’s approximately $75 billion asset base, even a 10-15% allocation to private markets translates to a multi-billion dollar commitment capacity. The trust has invested with established private equity firms and has shown willingness to back strategies across buyout, growth equity, and technology-focused venture capital.
The trust’s investment team evaluates private markets opportunities primarily on financial merit. Unlike some foundation endowments that integrate mission-related investment criteria into their private markets programs, the Gates Foundation separates its investment activities from its programmatic mission. The foundation’s impact is achieved through grantmaking rather than through the investment portfolio, which gives the trust’s team flexibility to pursue the highest risk-adjusted returns available regardless of sector or geography.
Fund managers should note that the trust’s annual IRS Form 990-PF filings are publicly available and provide detailed information about investment holdings and portfolio composition. These filings offer useful insight into the trust’s current positioning and can help managers understand where their strategies might fit within the existing portfolio.

The trust's IRS Form 990-PF filings show major holdings in companies like Berkshire Hathaway, along with diversified positions across global equities and fixed income. The trust also maintains allocations to private equity and venture capital, though these represent a smaller share of the total portfolio compared to public market investments.

How can fund managers engage with the Gates Foundation Trust?
The Gates Foundation Trust's investment team operates from Seattle and manages the portfolio with a relatively lean internal staff supplemented by external managers. Given the trust's scale and concentrated portfolio approach, opportunities for new manager relationships tend to be selective. Fund managers should understand that the trust evaluates investments primarily on financial merit, as the programmatic mission is executed through the foundation's grantmaking rather than through investment strategy. The trust does not typically issue public RFPs. Introductions through existing networks and institutional investor channels are the standard path to engagement.
