AI infrastructure stocks slide after report puts OpenAI revenue $20B below estimates

AI infrastructure shares fell on October 8 after the Financial Times reported that OpenAI's investor documents show annualized revenue nearing $50 billion, roughly $20 billion below figures circulated earlier. A source attributed the gap to OpenAI counting net rather than gross partner revenue. Oracle dropped about 5.5% and CoreWeave 8%, while the Nasdaq Composite had its worst session since mid-August.
