OpenAI Puts Annualized Revenue at About $50 Billion, Sparking Selloff in AI Stocks
· TexaHub · Artificial Intelligence, Semiconductors, Risks & Opportunities
OpenAI said its run-rate revenue was roughly $50 billion at the end of September, below the $68 billion figure that had circulated. AI-linked shares fell on 8 October, with the Philadelphia Semiconductor Index down 3.39%.
A Lower Headline Number
OpenAI told investors its annualized revenue run rate was about $50 billion at the end of September, below a widely cited figure of roughly $68 billion, according to Briefs, citing CNBC [1]. The higher number had folded in gross revenue from OpenAI's partners to facilitate comparisons with Anthropic, the report said [1].
BigGo Finance reported that OpenAI described the gap as primarily reflecting differences in accounting methodology compared with Anthropic [2].
Growth Metrics Disclosed
OpenAI pointed to 77% growth in total run rate in the third quarter and a 107% increase in enterprise run rate over that span [1]. Superpower Daily noted that the apparent $18 billion discrepancy reflects definitions rather than necessarily a performance shortfall on comparable terms, though some outlets framed the figure as $20 billion below projections [3].
Market Reaction
AI-linked shares fell on Thursday 8 October. Briefs reported Nvidia down 3%, Oracle 6%, CoreWeave 8%, AMD 4%, Broadcom 4%, Intel 5% and Super Micro Computer 5% [1]. BigGo's market summary put the Nasdaq Composite down 1.25% and the Philadelphia Semiconductor Index down 3.39% to 12,623.72 [2].
The report also linked Broadcom's and Oracle's declines to separate reports that both are arranging large financings for AI infrastructure [2].
Valuation and IPO Context
Briefs said OpenAI faces pressure to justify an $852 billion valuation ahead of an anticipated 2027 public listing, that it confidentially filed a prospectus in June, and that it may seek a further round of roughly $30 billion [1]. These details are reported by a single secondary outlet.
