Larry Ellison is the co-founder of Oracle, where he serves as executive chairman and chief technology officer. He co-founded the company in 1977 and led it as chief executive for decades before transitioning to the chairman-and-CTO role. Ellison's personal wealth, the large majority of it held in Oracle stock, made him one of the two or three wealthiest individuals in the world through 2025 and 2026, and its movements have tracked Oracle's share price as the company expanded its cloud and AI-infrastructure business.
Wealth and Oracle's AI-driven rally
Ellison's net worth rose sharply in 2025 and 2026 as Oracle stock climbed on demand for its cloud-computing capacity, much of it tied to AI workloads. Reporting in late 2025 described him briefly becoming the wealthiest person in the world after a single-day surge in Oracle stock added tens of billions of dollars to his holdings, surpassing Elon Musk; subsequent coverage placed his net worth in the range of roughly $190 billion to over $250 billion depending on the date and Oracle's price (Source: finance.yahoo.com; observer.com). Because his wealth is concentrated in Oracle equity, it is unusually sensitive to the company's AI-infrastructure narrative.
Role in AI infrastructure and Stargate
Oracle is one of the principal partners in the Stargate AI data-center initiative, a large-scale buildout of compute capacity, and Ellison has been a visible figure in announcements connecting Oracle's cloud business to AI demand. Coverage of his activities in 2026 also linked him to media and entertainment dealmaking, including transactions involving TikTok's US operations and a Paramount–Warner Bros. Discovery combination, reflecting interests beyond Oracle's core enterprise-software and cloud business (Source: observer.com).
