For years, technology entrepreneurs have sat comfortably at the top of global wealth rankings, with artificial intelligence acting as the rocket fuel behind their soaring fortunes. Marketed as a multi-trillion-dollar breakthrough, AI pushed company valuations to record highs and turned tech executives into some of the richest people on the planet.
Now, that rapid rise is facing a harsh reality check.
Concerns that AI stocks may be dangerously overvalued sparked a sharp market pullback this week, erasing billions from the personal wealth of major tech leaders — even though the year has barely begun.
Oracle cofounder Larry Ellison has been the hardest hit so far in 2026. Since January, his net worth has plunged by around $59 billion, with nearly $19 billion disappearing in just a few days, according to Bloomberg’s Billionaires Index. The losses came as investors pulled back from software stocks tied closely to AI growth.
Amazon founder Jeff Bezos has also felt the pressure, losing $14 billion since Tuesday, adding to his growing year-to-date decline.
Nvidia chief Jensen Huang, whose company became an AI powerhouse, has watched nearly $12 billion vanish from his fortune this year, including $7 billion this week alone. Former Microsoft CEO Steve Ballmer has taken an even heavier year-long hit, with close to **$29 billion wiped away so far.
The broader tech sector has suffered major damage as well. The S&P 500’s software and services index slid almost 4%, contributing to more than $62 billion in combined losses among top software billionaires.
Among the steepest drops were the founders of advertising firm AppLovin. CEO Adam Foroughi saw his wealth shrink by about 31%, losing roughly $7.8 billion, while former CTO John Krystynak’s fortune fell 30%, cutting $2.4 billion. Cofounder Andrew Karam also lost close to 29% of his wealth.
This sudden downturn is a sharp contrast to last year’s massive gains. According to a 2025 Oxfam report, the ten richest Americans added nearly $700 billion to their fortunes between 2024 and 2025, driven largely by booming tech stocks and excitement around AI.
Several major figures — including Ellison, Bezos, Zuckerberg, Jensen Huang, and Google founders Larry Page and Sergey Brin — each gained close to $70 billion in a single year.
But such explosive growth has made fortunes more fragile than ever.
Ellison experienced this volatility firsthand when Oracle’s stock soared after a strong earnings report, briefly making him the world’s richest person. Days later, his wealth dropped by $34 billion as investors reconsidered the company’s AI ambitions.
Adding to the uncertainty, new global competitors are shaking up the industry. Earlier this year, Chinese startup DeepSeek rattled markets with a low-cost AI model that erased $600 billion from Nvidia’s market value, triggering massive losses across the tech sector.
What once seemed like an unstoppable AI-driven wealth surge is now revealing its risks — and for tech’s richest figures, the era of easy gains may be coming to an end.
