IT Home reported on November 6 that, following the U.S. midterm elections, U.S. stocks faced a broad sell-off on November 5, with technology stocks and the AI hardware supply chain among the hardest-hit sectors.

According to Forbes’ real-time billionaires ranking, Elon Musk’s net worth fell by $91.2 billion in a single day. Dell Technologies founder Michael Dell, Nvidia CEO Jensen Huang, Oracle founder Larry Ellison and Meta founder Mark Zuckerberg also suffered sharp losses. The five lost a combined $152.9 billion in net worth (IT Home note: approximately 1.02 trillion yuan at the current exchange rate).

According to a November 5 Reuters report, investors reassessed the impact of the U.S. midterm election results on AI data center construction, worrying that a Democratic advantage in Congress could slow data center expansion. Technology and semiconductor stocks consequently faced concentrated selling. Reuters noted that the Philadelphia Semiconductor Index fell about 12% that day, its second-largest one-day decline on record.

All 3 major U.S. stock indexes closed sharply lower. According to Associated Press data, the Dow Jones Industrial Average fell 3.4%, the S&P 500 fell 4.4%, and the Nasdaq Composite fell 5.5%. The Nasdaq was down 11.9% from its recent high, entering correction territory.

Among individual stocks, Nvidia fell 9.3%, AMD fell 17.3%, Dell Technologies fell about 15%, and Tesla fell about 10.8%. Bloomberg reported that Tesla and SpaceX both saw intraday declines of about 11% that day, while stocks related to AI chips and data centers were among the hardest hit in the market sell-off.

According to Forbes’ real-time billionaires ranking, the one-day declines in net worth for 5 of the world’s technology billionaires were as follows:

Elon Musk: down $91.2 billion, a decline of 10.50%.

Michael Dell: down $20.5 billion, a decline of 9.60%.

Jensen Huang: down $15.1 billion, a decline of 8.70%.

Larry Ellison: down $13.2 billion, a decline of 8.05%.

Mark Zuckerberg: down $12.9 billion, a decline of 5.98%.

The 5 lost a combined $152.9 billion in net worth, with Musk’s loss alone accounting for about 59.6% of the total.
