On September 10, 2025, Oracle co-founder and executive chairman Larry Ellison became the world’s richest individual, surpassing Elon Musk via a jaw-dropping $100+ billion net-worth gain in a single trading session.
The Wealth Shake-Up
Oracle’s stock catapulted between 40–45% after a stellar earnings report and newly announced multi-billion-dollar AI-cloud contracts, including deals with OpenAI and other major AI players.
Ellison’s personal stake—about 41% of Oracle—realized a historic windfall. His net worth soared by approximately $101 billion, placing him just ahead of Musk.
As of that morning, Bloomberg’s Billionaires Index pegged Ellison’s net worth at around $393 billion, compared to Musk’s $385–$385 billion.
Why It Matters
This shift marks the largest single-day gain in net worth recorded by Bloomberg’s index, smashing previous records.
It underscores how deeply intertwined billionaire rankings are with market performance, particularly in high-growth sectors like AI and cloud infrastructure.
Musk’s drop was tied to Tesla shares’ decline, illustrating how fortunes rise—and fall—with share prices and earnings reports.
