Warren Buffett

Warren Buffett commands an estimated $149 billion as of early 2026, now age 96, through a significant stake in Berkshire Hathaway, a conglomerate spanning GEICO insurance, BNSF Railway, Berkshire Hathaway Energy, and a substantial equities portfolio historically anchored by a major stake in Apple. Buffett began investing at age 11 and compounded capital at roughly 20% annually for over 60 years, one of the most sustained investment track records in history. Having donated over $60 billion to charitable causes since 2006, including the Gates Foundation, before redirecting his giving toward family foundations in 2026, his net worth has continued growing through Berkshire's retained earnings and portfolio appreciation.
