Gates Foundation Concentrates $36 Billion Portfolio in Core Value Plays

The trust fund managing the Bill & Melinda Gates Foundation's assets has adopted a highly concentrated investment strategy, with 59% of its $36 billion portfolio invested in just three companies. This approach prioritizes businesses with sustainable competitive advantages over high-growth technology, notably excluding Microsoft from its top three positions. A cornerstone of the portfolio is Berkshire Hathaway, which holds a valuation exceeding $9 billion within the trust. This position is bolstered by annual contributions from Warren Buffett, though the foundation is required to distribute a portion of these assets annually to meet philanthropic spending mandates. Under the leadership of CEO Greg Abel, who took the helm in early 2026, Berkshire maintains a massive liquidity position of $373 billion in cash and Treasury bills, alongside $318 billion in marketable equities. Abel has identified Apple and various Japanese equities, such as Tokio Marine, as core long-term holdings, while restarting share repurchases as the stock's price-to-book ratio hit a multi-year low. Waste Management (WM) remains another long-term pillar of the trust. The company's dominance is secured by its extensive network of landfills and transfer stations, creating high regulatory barriers to entry. The company further expanded its footprint through the 2024 acquisition of Stericycle. For investors, the foundation's holdings signal a preference for indispensable infrastructure and diversified conglomerates. While some of these assets face valuation headwinds, the concentration suggests a conviction in the long-term resilience of these economic moats as Gates works toward giving away the bulk of his wealth by 2045.
