And there’s no question that Warren is leaving Berkshire in great hands with Greg.”

Mark Cuban called Buffett his “investing hero,” telling Business Insider that the pair used to go to the Dairy Queen in Omaha, where Buffett lived.

“It was the highlight of my year,” he said.

Bank of America (BAC) CEO Brian Moynihan said that “Warren Buffett has achieved unparalleled success over a seven-decade-plus career. Beyond his business success, his unprecedented philanthropic giving continues to be an example to follow.”

“His life lessons delivered to young and old are as valuable as his business acumen. I have personally learned so much from him and look forward to continuing to benefit from his insights,” Moynihan continued, according to Reuters. “He has been a tremendous supporter and investor in Bank of America and our nation’s economy and the innovative spirit of the United States.”

CNBC (CMCSA) host Jim Cramer said on X that he is “is awe of Buffett,” calling his career “the great run of all time.”

“Our only G.O.A.T,” he added, referring to Buffett as the “greatest of all time.”

Founder of Tolou Capital Management Spencer Hakimian posted a video of Buffett getting a standing ovation after announcing his retirement.

“Curtain call for the captain,” Hakimian said.

American Express (AXP) CEO and Chairman Stephen Squeri told Business Insider that Buffett “has had one of the most storied careers in the history of American business.”

He said Buffett’s “vision and deep sense of responsibility to shareholders is unmatched, and his humility and humor are rare qualities in a leader that have made working with Warren a delight.”
