About $150.5 billion was wiped off the estimated fortunes of eight of the world's richest men in a single Wall Street session on Thursday, November 5, 2026, as a sharp sell-off swept technology and AI stocks, according to Forbes' real-time billionaires list.
Elon Musk led the losses at $79.4 billion, about 9.1% of his fortune, which fell to $789.5 billion; he remains the world's richest person by a wide margin. Michael Dell lost $22 billion, nearly 10%, the largest relative drop among the main names, leaving him with $191.1 billion.
Nvidia's Jensen Huang lost about $15.8 billion and slipped to ninth place, while Larry Ellison lost $10.8 billion and fell to 11th, out of the top 10. Mark Zuckerberg lost $8.4 billion, Jeff Bezos $5.1 billion, Larry Page $4.7 billion and Sergey Brin $4.3 billion.
The Nasdaq fell 5.5%, the S&P 500 4.4% and the Dow 3.4%, while the Philadelphia Semiconductor Index dropped 12.2%. Nvidia fell 9.3%, losing more than $440 billion in market value; Dell Technologies dropped about 15%, Tesla 11%, SpaceX 9% and Oracle 7%, Reuters reported.
The losses reflect investor worries over heavy spending on data centers and chips, and whether it can earn returns that justify high valuations, compounded by midterm results that gave Democrats control of both chambers of Congress. The losses are largely on paper and may shrink or widen as share prices move.
