Gates Foundation's $86 Billion Portfolio Heavily Concentrated in Berkshire Hathaway The Bill & Melinda Gates Foundation, the charitable organization founded by Microsoft co-founder Bill Gates, manages a portfolio valued at $86 billion. According to a report from Yahoo Finance, the foundation’s equity holdings are heavily concentrated, with 96% of its portfolio’s value tied to its ten largest investments. A single stock accounts for 28% of the entire portfolio, but this is not Microsoft, the company Gates co-founded. Instead, the dominant position is held by Berkshire Hathaway (BRK.B), the conglomerate led by Warren Buffett. As of the end of 2025, the foundation owned approximately 19.4 million Berkshire Hathaway Class B shares, valued at around $9.8 billion. Other significant holdings include Waste Management (WM) and Canadian National Railway (CNI). Microsoft (MSFT) is the fourth-largest holding, representing a 10.5% allocation. The foundation’s investment in Berkshire Hathaway stems from annual charitable donations made by Buffett over decades. From 2006 to 2024, Buffett donated a total of $43.3 billion in Berkshire stock to the foundation. The foundation’s current $9.8 billion stake in Berkshire is lower than the cumulative donation because shares are sold over time to fund philanthropic activities. For example, in the final quarter of 2025, the foundation sold 2.36 million Berkshire shares, generating over $1 billion. This strategy aligns with Buffett’s intent to support charitable causes while managing the foundation’s financial resources. The foundation has deployed more than $102 billion in total philanthropy since its inception, reflecting its long-term commitment to global initiatives.#microsoft #berkshire_hathaway #warren_buffett #bill_melinda_gates_foundation #yahoo_finance
