Overview

• Oracle’s stock jumped 36% on Sept. 10 after strong results, lifting Larry Ellison’s fortune by $101 billion to about $393 billion and briefly topping Elon Musk, according to Bloomberg’s index.
• In the two days that followed, Ellison’s estimated net worth fell by $34 billion, and despite some recovery he remains roughly $23 billion below that peak.
• The volatility centers on a Wall Street Journal report that OpenAI agreed to buy roughly $300 billion of computing power from Oracle over five years, a figure investors are reassessing.
• Analysts highlighted feasibility and concentration risks, citing Oracle’s less established position in top-tier cloud and OpenAI’s far smaller revenue run rate relative to the reported multi-year commitment.
• Musk reclaimed the top spot with an approximately $35 billion gain that a Berkeley economist attributes to options-driven, sentiment trades ahead of Tesla’s shareholder calendar rather than new fundamentals.
