Warren Buffett’s Biggest Mistake Has Now Cost Berkshire Hathaway Up to $112 Billion (but I Don’t Blame Him)

October 8, 2026 · by TPW Pipeline

Trillion-dollar conglomerate Berkshire Hathaway (NYSE:BRKA)(NYSE:BRKB) entered 2026 in uncharted territory for the first time in more than half a century. On Dec. 31, Warren Buffett, the company’s longtime CEO, who oversaw a greater-than-6,000,000% outperformance of the benchmark S&P 500 since the mid-1960s, retired as CEO. His successor, Greg Abel, is now in charge of Berkshire’s $350 billion investment portfolio.

While the Oracle of Omaha had a knack for spotting amazing deals hiding in plain sight, he wasn’t infallible. Decisions made in the years leading up to his retirement with No. 1 holding Apple (NASDAQ:AAPL) have cost Berkshire Hathaway up to $112 billion in would-be gains.
