Anthropic has told investors that its annualised revenue run rate passed $65bn by late July 2026, according to Bloomberg reporting on 17 August. TechCrunch's write-up is unusually careful in defining the term, and the definition is the story: a run rate is "a projection of a full year's revenue based on a recent, shorter period."
The reported progression
About $9bn at the end of 2025, $47bn in May 2026, $65bn in late July. Investors are reported to expect the company to finish 2026 with annual revenue between $100bn and $120bn. Anthropic was last valued at $965bn in late May, when it raised a $65bn round, and is reported to be seeking a public valuation of $2tn or more, possibly as soon as this autumn. OpenAI is reported to have doubled to $40bn from $20bn at the end of 2025.
What the common framing gets wrong
Headlines saying revenue "surges to $65bn" describe money the company has not earned. Set the run rate against the most recent quarterly figure reported for Anthropic — above $11.5bn — and the quarter annualises to roughly $46bn. The July run rate is about 40% higher than the quarter that preceded it. Either growth accelerated very sharply inside the quarter, or the two numbers are measured on different bases. Both are possible; neither has been disclosed, because Anthropic has published no methodology and indeed has published none of these figures at all. The second error is the OpenAI comparison: two leaked figures, at different month-ends, on undisclosed and probably different bases, are not a league table.
Two different $65bns
A smaller trap worth flagging, because it is already appearing in coverage: the $65bn round Anthropic raised in May and the $65bn run rate it reported in July are the same number attached to entirely unrelated things — capital in, and revenue projected out.
Why it is being disclosed this way
None of this came from Anthropic. It came from investors, via Bloomberg and the Financial Times, at a moment when the company has filed confidentially for a listing and is reported to be seeking a valuation more than double its last private mark. A run rate is the most flattering revenue metric available, because it converts the single best recent month into a full year. It is also the metric a company cannot use in a prospectus, where audited historical revenue is required. The gap between the number circulating now and the number that will appear in the filing is the thing to watch.
