Oracle founder Larry Ellison’s historic run as the world’s richest person lasted just a single day, as Tesla’s market performance helped Elon Musk reclaim his title. The dramatic shift underscores the extreme volatility in the world of tech billionaires.
September 11, 2025: Larry Ellison is the richest person in the world because the price of Oracle’s stock, the company he co-founded and now runs, has gone up a lot.
The Bloomberg Billionaires Index claims that Ellison’s net worth rose by an amazing $101 billion in just one day, taking it to an amazing $393 billion. This big spike happened after Oracle said it had record sales and that its cloud services powered by AI will increase a lot. The stock price of the corporation rose by more than 40%, which was the highest one-day rise in its history. Ellison became a wealthy since he owns roughly 40% of the company’s equity.
The huge ascent has ended Elon Musk’s reign at the top. It went on for more than a year. Tesla’s stock price fell 13% in 2025, which caused the CEO’s net worth to drop from $385 billion.
Ellison’s journey to the top shows how the AI boom and the battle over cloud computing are changing who the richest people in the world are. In less than two months, he went from second to first position. This shows how weak and unpredictable the richest people in the world are.
