OpenAI told investors its annualized revenue hit roughly $50 billion at the end of September, about $20 billion below the $70 billion figure circulated last month. The disclosure sparked a sharp selloff in AI stocks on October 8. Nvidia fell 3%, Oracle dropped nearly 6%, and CoreWeave sank 8%. The Nasdaq Composite fell more than 1%, marking its biggest one-day loss since mid-August.

Why the revenue number fell short

The discrepancy stems from how OpenAI and rival Anthropic calculate revenue. Anthropic includes gross revenue from cloud partners like AWS and Google Cloud, while OpenAI does not, according to the Financial Times. OpenAI’s $50 billion figure excludes partner sales, making a direct comparison misleading. The $68 billion figure reported in late September included this partner revenue, the person familiar with the matter said.

Chipmakers and AI infrastructure stocks tumble

Beyond Oracle and CoreWeave’s sharp declines, Advanced Micro Devices fell 4%, Broadcom dropped 4%, Intel slid 5%, and Super Micro Computer fell nearly 5%. Kristina Hooper, chief market strategist at Man Group, warned that “if we have a number of days like this, we could see a real rout in AI-related names.” The selloff dragged the S&P 500 down 0.5% for its second straight day in the red.

OpenAI’s growth rate and IPO pressure

Despite the lower revenue base, OpenAI reported 77% total run rate growth in Q3 and 107% run rate growth for its enterprise business during the same period. The company is under pressure to justify its $852 billion valuation ahead of an expected 2027 IPO. OpenAI confidentially filed its prospectus with regulators in June, with executives signaling a 2027 debut. Rival Anthropic, which reported $65 billion annualized revenue at end of July, is also preparing for a major IPO and seeking a $2 trillion valuation.

Broader market reaction and Asia fallout

U.S. stock futures were near flat Thursday night after the report. S&P 500 futures rose 0.09%, while Nasdaq 100 futures added 0.05%. In Asia on Friday, Japan’s Nikkei 225 lost 0.76%, while Australia’s S&P/ASX 200 added 0.37%. The revenue miss also raised questions about valuation metrics used by fast-growing Silicon Valley startups, which often multiply a single month’s revenue by 12 to project annual figures.

Final Thoughts

OpenAI’s $50 billion revenue disclosure, $20 billion below prior estimates, exposed how different calculation methods can mislead investors. The selloff in chipmakers and AI infrastructure firms signals renewed caution in the AI trade, though OpenAI’s 77% growth rate and 2027 IPO timeline remain key catalysts.
