On Thursday, a sudden slump in U.S. technology stocks erased billions from the fortunes of five of the world’s richest founders. The rapid decline shows how closely billionaire wealth is tied to share prices.

Elon Musk experienced the steepest hit, with his net worth dropping $79.4 billion, a 9.13% fall, to $789.5 billion after Tesla shares plunged 11.5% on Thursday. Forbes’ real‑time tracker recorded the change.

Michael Dell’s fortune shrank by $22 billion, leaving him with $191.1 billion, as the broader downturn in technology‑hardware stocks weighed on Dell Technologies. Jensen Huang lost $15.8 billion, bringing his wealth to $157.9 billion after Nvidia shares fell 9.3% amid worries about AI‑chip demand.

Larry Ellison slipped to $153.3 billion, down $10.8 billion, as Oracle shares continued to slide in the tech sell‑off. Mark Zuckerberg’s wealth declined $8.4 billion to $208 billion while Meta grappled with a wider technology sell‑off and high AI‑infrastructure spending.

Even after losing a combined $136 billion, all five men remain among the world’s wealthiest individuals. Their experience underscores how quickly market sentiment and AI‑related concerns can reshape billionaire net worth.
