Warren Buffett plans to donate entire Berkshire Hathaway stake by 2034

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.

In November 2025, Buffett stepped down as CEO of Berkshire Hathaway. The philanthropic acceleration followed almost immediately.

The Gates Foundation break is the real headline

For nearly 20 years, one of the most reliable events on the philanthropic calendar was Buffett’s annual mid-year donation to the Bill and Melinda Gates Foundation. It did not happen in 2026. That is the first time that streak has broken since Buffett began making those contributions.

What this means for Berkshire shareholders

Buffett has historically structured his donations to minimize market disruption. He donates Class B shares, which are far more liquid than Class A, and staggers the transfers over time rather than dumping a single block. The 2034 deadline spreads the remaining distributions across roughly nine years.

Berkshire’s successor leadership under Greg Abel, who took over as CEO at the end of 2025, will be managing this transition alongside the normal business of running one of the largest conglomerates in the world.
