Mark Zuckerberg Gains $13.21B in a Day as META Jumps 5.97%

Mark Zuckerberg added $13.21B of net worth on July 12, 2026, one of the day's biggest moves among the world's richest people. The swing (+$13.21B, or 5.26%) leaves the fortune at an estimated $264.22B, ranked #5 on our real-time list.

The move traces to META, the listed company behind most of the fortune, which climbed 5.97% on the day to 669.21 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 Larry Page, who sits one place higher at $265.03B — now $802.50M away. Behind, Sergey Brin follows at $254.31B.

Co-founder, chairman, and CEO of Meta Platforms (Facebook, Instagram, WhatsApp).
