Oracle market value falls nearly 50% from $933 billion September 2025 record high

Oracle’s market capitalization has dropped by more than $463 billion from its all-time high of $933 billion in September 2025, cutting its valuation by just under 50%. The slide has pushed the company out of the top 10 most valuable U.S. firms as investors question heavy AI infrastructure spending, Oracle’s exposure to OpenAI, and rising credit risk following its December earnings.
