9 tech titans took a $150 billion wealth hit during Thursday's AI stock plunge — with Elon Musk alone losing $80 billion

What happened

On Thursday, nine of the world's wealthiest tech leaders lost a combined $152 billion in personal wealth after a steep drop in AI and semiconductor stocks. The Nasdaq 100 index fell by more than 6%, marking its worst single-day performance since the COVID-19 pandemic. Elon Musk experienced the largest individual loss, with his net worth decreasing by about $80 billion as shares of Tesla and SpaceX declined sharply. Other tech billionaires, including Michael Dell, Jensen Huang, Larry Ellison, Mark Zuckerberg, Steve Ballmer, Larry Page, Sergey Brin, and Jeff Bezos, also saw significant reductions in their fortunes.

Key details

• Elon Musk's net worth dropped by $80 billion, or over 9%, to $785 billion.
• Michael Dell lost about $19 billion, a decline of over 9%, with Dell Technologies stock down 15%.
• Jensen Huang's wealth fell by $15 billion, or 9%, to $151 billion, as Nvidia shares dropped 9%.
• Larry Ellison's fortune decreased by $10 billion, or 6%, with Oracle stock down 7%.
• The Nasdaq 100 index fell by more than 6% in one day.

Why it matters

Major tech company leaders and shareholders were directly affected by the sharp decline in stock prices, resulting in large single-day losses in personal wealth. Investors in AI and semiconductor sectors faced immediate reductions in portfolio values, and companies like Tesla, Dell, Nvidia, and Oracle saw their market capitalizations shrink. The drop also introduces new financial pressures for these firms and their investors, especially following recent gains tied to AI market growth.
