Jeff Bezos Gains $8.14B in a Day as AMZN Jumps 3.9%

Jeff Bezos added $8.14B of net worth on July 31, 2026, one of the day's biggest moves among the world's richest people. The swing (+$8.14B, or 3.28%) leaves the fortune at an estimated $256.66B, ranked #3 on our real-time list.

The move traces to AMZN, the listed company behind most of the fortune, which climbed 3.9% on the day to 235.50 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 Michael Dell, who sits one place higher at $303.37B — now $46.71B away. Behind, Larry Page follows at $248.56B.
