Gates Renames His Personal Office bgC3, the Seed of Gates Ventures
[RECORD.TXT] · cat --full
In 2008, after stepping back from full-time work at Microsoft, Bill Gates formally established bgC3 ('Bill Gates Catalyst 3') — a private think tank and holding company housing his personal staff, research interests, and technology investments. Later renamed Gates Ventures, the entity became the engine behind Gates Notes, his books, and his many science and energy bets. It marked the institutional beginning of Gates's 'third career' beyond Microsoft and the foundation.

Gates Foundation Trust Sells Off the Last of Its Microsoft Stock
In the first quarter of 2026, the Bill & Melinda Gates Foundation Trust sold its remaining Microsoft shares, fully exiting a position in the very company that created Gates's fortune — capping a long, deliberate diversification away from the stock. The endowment that funds Gates's philanthropy, managed separately from its grant-making through Cascade, is now anchored instead by Berkshire Hathaway, Waste Management, railroads, and heavy-equipment makers. The sale underscored how thoroughly Gates's giving had decoupled from Microsoft's day-to-day fortunes.

Gates's Charitable Endowment Is Now Led by Berkshire, Not Microsoft
By 2026, the publicly disclosed stock portfolio of the Bill & Melinda Gates Foundation Trust — the endowment that funds Gates's philanthropy — was led not by Microsoft but by Berkshire Hathaway, Waste Management, Canadian National Railway, Caterpillar, and Deere. Decades of diversification, plus Warren Buffett's stock gifts, left it concentrated in railroads, waste, heavy equipment, and Buffett's conglomerate, while Microsoft — the source of the original fortune — had largely been sold down. The unglamorous, value-oriented mix reflects the long stewardship of Gates's money manager, Michael Larson, through Cascade Investment.
