Elon Musk Loses $4.63B in a Day as TSLA Slides 2.96%

Elon Musk lost $4.63B of net worth on July 21, 2026, one of the day's biggest moves among the world's richest people. The swing (-$4.63B, or 1.14%) leaves the fortune at an estimated $401.89B, ranked #1 on our real-time list.

The move traces to TSLA, the listed company behind most of the fortune, which fell 2.96% on the day to 369.57 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.
