- Larry Ellison took a $25 billion hit to his net worth after Oracle shares plunged.
- This marks one of the biggest single-day wealth drops in 2025.
- Ellison briefly took the top spot as the world's richest person in September.
Larry Ellison just took a $25 billion hit to his net worth.
The Oracle cofounder saw billions wiped off his fortune on Thursday, according to estimates on Bloomberg's Billionaire Index, after the software giant's shares fell by more than 11% on weaker-than-expected earnings results.
The hit brought Ellison's net worth down to $258 billion, per the Index, marking one of the biggest single-day wealth drops of 2025.
Other billionaires suffered steeper or similar losses in April: Elon Musk lost $35 billion in just three days, and Mark Zuckerberg shed about $24 billion as Trump's tariff plans sparked fears of retaliation and recession.
Earlier this year, Ellison briefly took the crown of world's richest person, overtaking Musk in September when Oracle shares surged as much as 43% due to a strong forecast for its cloud business.
Oracle missed Wall Street's revenue expectations in its most recent earnings results, which were reported on Wednesday. Shares fell more than 11% in after-hours trading, extending a slide that began in October as investors questioned the company's breakneck spending on artificial intelligence infrastructure.
Despite missing estimates, revenue was up 14% year-over-year during the quarter. But that wasn't enough to calm concerns over the scale and cost of its expansion.
Those worries dominated Wednesday's call with analysts.
Clay Magouyrk, Oracle's co-CEO, pushed back on fears that the company might need more than $100 billion to build out its data centers — a figure some analysts had floated.
"We expect we will need less, if not substantially less, money raised than that," he said, adding that Oracle's debt remains "investment-grade."
Even after Thursday's plunge, the Bloomberg Billionaires Index shows that Ellison's net worth still remains ahead of most tech titans, including Jeff Bezos and Mark Zuckerberg.
