Warren Buffett Retires as Berkshire Hathaway CEO

Warren Buffett officially retired as CEO of Berkshire Hathaway on December 31, 2025, passing leadership to Greg Abel, who has been with the company for over 25 years. Under Buffett’s tenure, Berkshire transformed into a trillion-dollar entity, with Class A shares increasing nearly 6.1 million percent and a portfolio exceeding $300 billion.

Prior to his retirement, Buffett significantly reduced Berkshire’s stake in Amazon by approximately 77%, equating to nearly $1.7 billion, raising questions about valuation amidst soaring AI expenditures. Conversely, he invested over $4 billion in Alphabet, acquiring 17,846,142 Class A shares, which boast a dominant market presence with around 89-93% of global search traffic.

Buffett’s actions have drawn attention as the market is experiencing high valuations, noted as the second priciest since January 1871, prompting him to sell off stocks as part of a net $187 billion reduction in investments leading up to his departure.
