Il Nuovo Postiglione - OpenAI revenue gap report rattles AI stocks

Citing documents shared with OpenAI's financial backers, the FT said the company put its annualized revenue at close to $50 billion as of the end of September.

Media reports late last month had pegged the figure at $70 billion based on information given to investors.

Investors track annualized revenue at OpenAI and Anthropic as the clearest signal of demand for artificial intelligence, and the figures help justify enormous spending on data centers as well as the AI-fueled stock market rally.

The metric, which tech startups commonly use to signal their growth trajectory, is sometimes criticized as imprecise or even misleading, since it typically extrapolates a single month's sales across a full year.

In an apparent pushback, a person familiar with the matter told CNBC that the earlier number, which the network reported as $68 billion, counted gross revenue from OpenAI's partnerships with companies like chipmaker Nvidia.

That method was intended to make it easier for investors to measure the company against chief rival Anthropic.

The report weighed on AI-linked stocks, with Nvidia down 2.9 percent, SpaceX down four percent and Oracle losing nearly six percent.

OpenAI did not immediately respond to AFP's request for comment.

The report lands as OpenAI negotiates a fresh private fundraising that could value it at roughly $1.4 trillion, according to the FT.

OpenAI, which confidentially submitted paperwork for an initial public offering in June, had been widely expected to go public this fall, but it has since pushed back the listing.

Archrival Anthropic is expected to list on the public markets next month.
