How Did Larry Ellison Surpass Elon Musk as the Richest Man For Just One Day?
Summary
In September 2025 Larry Ellison briefly became the world’s richest person after Oracle’s stock jumped following stronger-than-expected earnings and a wave of AI and cloud-related contract announcements. Ellison’s roughly 41% stake meant Oracle’s surge translated into an extraordinary one-day personal gain of about $100 billion, lifting his net worth to an estimated $393 billion and nudging him past Elon Musk.
Elon Musk reclaimed the top spot within days as Tesla shares recovered and his diversified holdings regained momentum. The episode highlights how market sentiment around AI and cloud strategy can rapidly revalue large public companies and the fortunes of their founders.
