A sudden drop in Oracle’s stock delivered a major blow to Larry Ellison’s wealth. On Thursday, shares of the software giant fell more than 11% after earnings missed Wall Street expectations.
As a result, Bloomberg’s Billionaires Index estimated that Ellison lost nearly $25 billion in a single day. That decline pushed his net worth down to about $258 billion, marking one of the steepest one-day losses of 2025.
What Triggered the Market Reaction
Oracle reported its latest earnings on Wednesday, and investors reacted quickly. Although the company posted a 14% year-over-year revenue increase, the numbers still fell short of analyst forecasts.
Consequently, concerns returned around Oracle’s aggressive spending on artificial intelligence infrastructure. Those worries had already pressured the stock since October, and this report intensified the scrutiny.
At the same time, investors focused heavily on the scale of Oracle’s data center expansion. Some analysts suggested costs could exceed $100 billion.
However, co-CEO Clay Magouyrk pushed back during the earnings call. He explained that Oracle expects to raise far less capital than those estimates suggest and emphasized that the company’s debt remains investment-grade.
How This Loss Compares Across Tech Leaders
While Ellison’s loss stands out, other tech billionaires have faced similar setbacks this year. Earlier in April, Elon Musk saw $35 billion erased over three days. Meanwhile, Mark Zuckerberg lost roughly $24 billion as market fears grew around tariffs and economic slowdown. Even so, Ellison still ranks ahead of most tech leaders in overall net worth.
Despite the plunge, Ellison remains among the wealthiest individuals in the world. Earlier this year, Oracle’s stock surge briefly lifted him above Musk as the richest person globally.
Now, although the stock stumbles, Oracle’s long-term cloud ambitions continue to shape investor debate and market movement.
