Warren Buffett Gains $3.16B in a Day as BRK-B Jumps 3.06%

Warren Buffett added $3.16B of net worth on July 29, 2026, one of the day's biggest moves among the world's richest people. The swing (+$3.16B, or 3%) leaves the fortune at an estimated $108.57B, ranked #11 on our real-time list.

The move traces to BRK-B, the listed company behind most of the fortune, which climbed 3.06% on the day to 512.37 USD per share. Because a billionaire's wealth is concentrated in stock, daily net worth simply follows the share price multiplied by the shares held.

The gain narrows the gap to Bernard Arnault, who sits one place higher at $132.46B — now $23.89B away. Behind, Alice Walton follows at $106.55B.
