Nvidia, AMD shares fall as OpenAI revenue report rattles AI investors
Nvidia and AMD shares fell on October 8, 2026, after a Financial Times report indicated OpenAI's annualized revenue run rate was $50 billion, below the expected $70 billion. Nvidia dropped 2.9% to $230.60, while AMD declined 4.55% to $616.48. Analysts attributed the market reaction to accounting differences, not a slowdown in AI demand, and noted OpenAI's enterprise segment grew 107%.
