Anthropic’s Numbers Got Bigger, Not Simpler

Anthropic told investors it generated $16.8 billion in revenue between July and September, up 46% from $11.5 billion in the previous three months, according to Euronews, which cited Bloomberg reporting on the presentation. Ahead of a planned initial public offering, that is the number meant to command attention. The more useful one may be the rate of change: 46% quarter-on-quarter is still ferocious growth, but it is slower than the leap from the first quarter to the second.

That distinction matters because Anthropic is reportedly seeking a valuation of as much as $2 trillion in an IPO planned for November. At that altitude, investors are not paying for revenue alone. They are paying for the assumption that the company can keep converting AI demand into something sturdier than excitement.

Anthropic also told investors it was profitable for a second straight quarter on an adjusted basis, Euronews reported, with positive free cash flow and an 11% operating margin on the same adjusted measure. Useful figures, with a familiar caveat: “adjusted” is finance’s polite way of asking you not to look at every cost at once. It can still tell you something real about the business, especially cash generation, but it does not settle the question of what the fully burdened economics look like.

That question is not academic here. Euronews said a draft prospectus reported by other outlets showed Anthropic lost $42 billion on standard accounting measures in 2025, on revenue of $4.6 billion, largely because of $34 billion in accounting charges tied to past fundraising. Those charges may not describe the operating engine cleanly, but they do describe the price of building one in a capital-hungry industry.

Anthropic’s own efficiency marker was more flattering. The company reportedly said each dollar spent on computing power brought in $1.70 of revenue in the quarter. That helps explain why public-market investors may be willing to entertain a valuation once reserved for the largest, most entrenched businesses on earth. It also shows what this market cares about now: not whether AI is expensive — that case is closed — but whether the expense scales into cash before competitors make the product cheaper.

There is already some evidence the slope is changing. Euronews reported that annualised revenue is now expected to end 2026 below $100 billion, short of what some backers had previously anticipated. SemiAnalysis, cited by Euronews, put the current annualised figure at about $74 billion, up from roughly $65 billion in late July. That is growth, just not the kind of growth that lets every prior valuation target look conservative in hindsight.

The OpenAI comparison floating around the story is tempting and not especially clean. Euronews said OpenAI was approaching $50 billion in annualised revenue at the end of September, while noting the two companies count revenue differently. In other words, the race is real, the scoreboard is smudged.

Anthropic confidentially filed for an IPO in June and has not yet published its full prospectus, Euronews reported. Until that filing is public, investors are being asked to admire the velocity before they can inspect the whole machine.
