Warren Buffett has committed to donating his entire remaining stake in Berkshire Hathaway to four family foundations by December 31, 2034, setting a concrete deadline on one of the largest wealth transfers in modern history.
The numbers behind the commitment
Buffett has already donated more than $60 billion, almost entirely in Berkshire Class B shares. His most recent gift, made in June 2025, set a personal record at $6 billion in a single transaction.
The four foundations receiving his remaining shares are the Susan Thompson Buffett Foundation, the Sherwood Foundation, the Howard G. Buffett Foundation, and the NoVo Foundation. All four are run by or connected to his family, which is a deliberate choice: Buffett wants to oversee the distributions while he is still alive, rather than leaving the work to an estate process he cannot supervise.
The original Giving Pledge framework gave his estate up to 10 years after his death to complete charitable distributions. Critics called that timeline unrealistic. The 2034 date compresses the window and puts Buffett himself in the room when decisions get made.
