What is Little Bighorn?

After leading his financial conglomerate for more than six decades, Warren Buffett is stepping down as Berkshire Hathaway chairman, effective immediately. Buffett has transitioned to the role of chairman emeritus and will remain on the company’s board of directors.

Greg Abel took over as CEO of the $1 trillion organization in early 2026. While Buffett continued to visit the office daily, he indicated he is now ready for a slower pace.

“Recently, I celebrated my 96th birthday with family and friends, including one of my great-grandchildren, who had just turned one. He’s moving a bit faster than I am these days,” Buffett wrote in a letter to shareholders. The billionaire credited Abel with exceeding his “sky-high” expectations, giving him complete confidence in completing the transition.
