Oracle's stock price fell 4.5% on Monday (September 14), primarily due to multiple factors. On one hand, AI companies such as Anthropic and OpenAI called for stronger AI regulation, leading to widespread pressure on the AI sector. On the other hand, last week's inflation data and rising oil prices intensified market concerns that the Federal Reserve might raise interest rates at its next meeting, which could increase Oracle's costs for expanding its AI data centers. Furthermore, co-founder Larry Ellison's decision to abandon plans to sell up to $7.5 billion worth of company stock, a move typically seen as positive, failed to offset the aforementioned negative impacts.
