Elon Musk Loses $4.20B in a Day as TSLA Slides 2.61%

Elon Musk lost $4.20B of net worth on July 18, 2026, one of the day's biggest moves among the world's richest people. The swing (-$4.20B, or 1.02%) leaves the fortune at an estimated $406.53B, ranked #1 on our real-time list.

The move traces to TSLA, the listed company behind most of the fortune, which fell 2.61% on the day to 380.84 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.
