Anthropic's $65B revenue run rate sets up record $2 trillion IPO

The Claude maker's annualized revenue jumped sevenfold in seven months, positioning it to beat OpenAI to the public markets — as OpenAI counters with a privacy-first safety pitch to enterprise buyers.

Anthropic’s annualized revenue run rate crossed $65 billion at the end of July 2026, a sevenfold jump from the $9 billion it reported at the end of 2025, according to figures the company shared with investors and first reported by Bloomberg. The trajectory sets up an October listing that the Financial Times pegs at a $2 trillion valuation, which would be the largest public offering ever, comfortably ahead of SpaceX.

The intermediate data points are almost more striking than the endpoints. Anthropic sat at a $47 billion run rate in May. Q1 2026 revenue landed at $4.73 billion. The most recent completed quarter came in above $11.5 billion, a sequential jump of more than 140%, against $787 million in the corresponding period of 2025. Backers now expect the run rate to reach $100 billion to $120 billion by year-end.

OpenAI isn’t standing still, but it’s on a different curve. Bloomberg reports its annualized revenue has doubled to $40 billion from $20 billion at the end of 2025. Impressive in any other cycle. Here, it’s the number that Anthropic already lapped.

The commercial story is boringly specific: unit economics. “Anthropic was much more token efficient than OpenAI but OAI has closed some of the gap,” Gavin Baker of Atreides Management told Axios. Harrison Rolfes at Pitchbook framed it in procurement terms: “Opus 4.8 can have a lower cost per successfully completed task than competing models.” Enterprises aren’t buying vibes. They’re buying task completion per dollar, and Claude is winning that spreadsheet.

Which explains the timing of this week’s counterpunch from OpenAI, previewing Private Safety Processing, an automated system positioned squarely at enterprise buyers reportedly irritated by Anthropic’s 30-day retention of user sessions and conversations. It’s a narrative-management move dressed as a product launch, aimed at the one soft flank in Anthropic’s IPO story.

Morgan Stanley, Goldman Sachs, and JPMorgan are working on the offering, with a listing expected in September or October. Both companies have filed confidential IPO paperwork. The 2020 direct-listing era produced ambitious debuts; none of them tried to price in a run rate that had septupled in seven months. The public markets are about to learn whether they believe the second derivative or just the first.
