In a breathtaking swing on September 10, 2025, Larry Ellison, co-founder and chairman/CTO of Oracle, temporarily surpassed Elon Musk to become the world’s richest person. Oracle shares surged by over 40%—fueled by strong quarterly earnings and massive contract wins—pushing Ellison’s net worth to approximately $393 billion, about $101 billion more than Musk’s estimated $292-$385 billion range, depending on the index.
Ellison’s wealth spike was driven especially by Oracle’s AI-cloud infrastructure business. The company announced four multi-billion-dollar deals and reported its remaining performance obligations (a metric indicating future contracted revenue) had jumped to about $455 billion, a sharp year-over-year growth of 359% Much of the investor enthusiasm came from AI firms’ hunger for computing power, including deals with names like OpenAI, xAI, Meta, Amazon, and others. The article paints a picture of Ellison as more than just a tech billionaire; he’s now seen as a major infrastructure figure in the AI boom. His 41% stake in Oracle means he benefits massively from the company’s share price rise. Aside from Oracle, he holds other assets: part-ownership in Tesla, a private Hawaiian island (Lana’i), a tennis tournament, and a sailing team. These add color to his profile, but the Oracle surge is what vaulted him passed Musk—for now.
The surge was brief; financial rankings like these tend to fluctuate as stock prices adjust. It’s not yet clear if Ellison will hold the top spot for long, especially since different indices value assets differently (for example, private holdings like Musk’s SpaceX). But regardless of how long the lead lasts, this event has underlined the massive value of AI infrastructure in the market’s eyes—and how key such infrastructure is becoming in the race for tech dominance.
Ellison’s story here isn’t just about personal wealth; it’s about a shift in tech investor priorities. What gets priced higher now is not always the flashy consumer tech, but the backbone that powers AI—data centers, cloud capacity, computing cores. The market is increasingly rewarding being the essential platform, not just the visible gadget. For newcomers and incumbents alike, that’s changing what “being dominant in tech” looks like.
