TLDR: Larry Ellison, co-founder of Oracle, briefly became the world’s wealthiest individual, surpassing Elon Musk, due to a significant surge in Oracle’s stock. This unprecedented rise was fueled by robust forecasts for its AI-powered cloud business and several multi-billion dollar artificial intelligence contracts, including a massive deal with OpenAI.
In a remarkable turn of events this week, Oracle co-founder Larry Ellison briefly claimed the title of the world’s richest person, momentarily surpassing Tesla and SpaceX CEO Elon Musk. This fleeting but significant shift in the billionaire rankings, occurring around September 10-11, 2025, was directly attributed to a dramatic surge in Oracle’s stock price, driven by its booming artificial intelligence (AI) cloud business.
Oracle’s shares experienced an extraordinary jump, spiking by over 40% to approximately 43% at one point, reaching a record high. This propelled Ellison’s net worth to an unprecedented estimated $393 billion, according to the Bloomberg Billionaires Index, briefly outpacing Musk’s $385 billion. The surge was underpinned by strong forecasts for Oracle’s cloud division and a flurry of major AI deals. CEO Safra Catz revealed that Oracle had secured four multi-billion dollar contracts in the last quarter alone, with more anticipated.
A cornerstone of this growth is a reported five-year cloud computing contract with OpenAI, valued at an astounding $300 billion, marking one of the largest cloud deals in history. Oracle is also actively involved in the $500 billion Stargate AI infrastructure project, further solidifying its position in the burgeoning AI sector. The company projects its cloud revenue to soar by 77% this year, reaching $18 billion, with continued expansion expected in the coming years.
Ellison, 81, whose substantial wealth is largely derived from his approximately 41% stake in Oracle, saw his fortune increase by around $100 billion in a single day. This meteoric rise underscores Oracle’s pivotal role in providing the essential cloud infrastructure and data centers that AI companies desperately need to power their advanced models. The demand from AI firms eager to leverage Oracle’s capabilities has fueled significant investor optimism.

While Ellison’s reign at the top was short-lived, with Oracle’s shares cooling by the end of trading and restoring Musk’s position, the event served as a powerful reminder of the central and transformative role AI and cloud infrastructure play in today’s technology landscape and, consequently, in shaping personal fortunes. This development highlights a broader trend where wealth is increasingly tied to the technologies driving future innovation, with artificial intelligence at the forefront.
