OpenAI recently disclosed to investors that, as of the end of September, the company's annualized revenue scale was about $50 billion, lower than the $70 billion widely reported by the market at the end of last month. People familiar with the matter said the difference stems from different statistical calibers: Anthropic includes sales revenue generated by cloud partners in revenue, while OpenAI does not use this method. OpenAI also disclosed that overall revenue run-rate grew 77% in the third quarter, enterprise business revenue run-rate grew 107%, and it confidentially submitted listing documents in June this year. On October 10, Rohan Paul cited an FT report to further explain that OpenAI calculates based on net income after deducting the share of partners such as Microsoft, while Anthropic calculates based on gross sales through cloud partners; both methods comply with US GAAP; the report said the $70 billion ARR was not announced by the company itself, but was derived by investors after upward adjustment according to Anthropic's caliber.

On September 27, 2026, AI infrastructure company Fluidstack completed a $1.5 billion funding round at a post-money valuation of $18 billion. According to a same-day report by Huxiu, the round was led by quantitative trading giant Jane Street, and Fluidstack's valuation rose from $7.5 billion to $18 billion within 60 days. The report said its core asset is a multi-billion-dollar computing power contract signed with Anthropic, and that it is participating in Anthropic's plan to deploy up to 1 million Google TPUs, becoming the first publicly disclosed TPU data center operator other than Google. The report also noted that this kind of circular financing, in which the funder simultaneously acts as customer and guarantor, carries systemic risks, and that Fluidstack's revenue is highly concentrated in a single customer such as Anthropic. There are currently no subsequent developments.
