Warren Buffett Set a New Goal: Give Away All of His $140 Billion Berkshire Stake by 2034

Warren Buffett will donate his entire $140 billion Berkshire Hathaway stake to charity by December 31, 2034, requiring approximately $17 billion in annual grants over the next eight years. This week, Buffett converted 8,000 Class A shares into 12 million Class B shares for donation to four family-tied foundations, marking an acceleration of his philanthropic timeline.

The structured liquidation plan aims to minimize stock price volatility by spreading the donations gradually across eight years. While the move reduces Buffett's ownership stake over time, the predetermined schedule provides transparency on future Class B share supply increases. The conversion mechanism—each Class A share converts to 1,500 Class B shares—means additional conversions totaling roughly $140 billion in market value will flow into the charitable pipeline by the 2034 deadline.

Buffett's Class A holdings currently represent a significant portion of Berkshire's float. The systematic drawdown through Class B conversions adds a known technical factor for traders tracking share count and voting structure changes.
