Warren Buffett, the legendary billionaire investor, has stepped down as Chief Executive Officer of Berkshire Hathaway Inc., ending a 60-year tenure at the helm of the multinational conglomerate.
Gatekeepers News reports that Buffett’s resignation took effect on Wednesday, December 31, 2025, marking the final day of his service as CEO. The move follows an announcement made in his annual CEO letter in November 2025, where he outlined plans for a leadership transition.
Under the arrangement, Buffett handed over executive leadership to Greg Abel, the CEO of Berkshire Hathaway Energy and vice-chairman overseeing the company’s non-insurance operations.
“I can’t think of a CEO, a management consultant, an academic, a member of government — you name it — that I would select over Greg to handle your savings and mine,” Buffett said at the time.
While Abel officially assumes the role of CEO from January 1, 2026, Buffett is expected to remain chairman of Berkshire Hathaway.
Nicknamed the “Oracle of Omaha,” Buffett is widely regarded as one of the most successful investors in history. He transformed Berkshire Hathaway from a struggling textile manufacturer into a vast global conglomerate spanning insurance, energy, manufacturing, retail and consumer goods.
The 94-year-old investor has an estimated net worth of $152 billion and is currently ranked as the world’s tenth-wealthiest individual, according to the Bloomberg Billionaires Index.
Buffett has also inspired generations of business leaders and investors, including Microsoft founder Bill Gates and Pershing Square founder Bill Ackman.
Under his leadership, Berkshire Hathaway grew into one of the world’s most valuable companies, with a market capitalisation exceeding $1 trillion, according to CompaniesMarketCap. The conglomerate owns dozens of major businesses, including insurer Geico, battery maker Duracell and restaurant chain Dairy Queen.
