A Number Anthropic Has Not Confirmed
Every account of Anthropic's second quarter starts with the same caveat: the $11.5 billion figure comes from Bloomberg's sources inside the company's own documents, not from a statement Anthropic issued or an audited filing. That distinction matters more than usual here, because Anthropic is mid-way through a confidential IPO process, and internal numbers shared with prospective investors are, by definition, meant to be persuasive before they are meant to be exact.
What is not in dispute is the shape of the trend. Revenue went from $787 million in the second quarter of 2025 to $4.73 billion in the first quarter of 2026 to more than $11.5 billion in the second quarter, a run of growth few software businesses of any kind have matched, and the company recorded positive adjusted operating income for the first time in the same period.
Where the Margin Actually Came From
The Wall Street Journal's earlier reporting, corroborated by CNBC, PYMNTS and The Decoder within a day of publication, gives the clearest account of how the margin moved. Anthropic's compute cost fell from 71 cents to 56 cents for every dollar of revenue between the first and second quarter, a 15-cent swing in a single quarter that would be remarkable for any infrastructure-heavy business.
Three things drove it: a growing share of revenue from coding products billed per seat or per task, which carry thicker margins than raw inference; a tokenizer change in Opus 4.7 that raised the number of tokens processed per request by roughly 47 percent, letting Anthropic lift realized prices 20 to 30 percent without touching its published per-token rate; and two multi-year compute commitments, $40 billion with Google for TPU capacity and $33 billion with Amazon for AWS capacity, both struck as part of funding rounds in which Google and Amazon also took equity.
The Question an Autumn Prospectus Has to Answer
Google and Amazon are not neutral vendors here. Both are Anthropic shareholders as well as its two largest compute suppliers, and the compute commitments behind this quarter's margin gain were negotiated as part of the same funding rounds that gave them their stakes. That does not make the $11.5 billion fake, but it does mean a chunk of the margin improvement reflects the pricing an investor-supplier is willing to offer, not the price a standalone enterprise customer would be quoted for the same capacity on the open market.
For anyone evaluating the autumn listing, that is the number worth isolating before the headline profit figure sets a valuation multiple: what would this quarter's operating income look like if the TPU and AWS capacity were billed at the rate Anthropic's own paying customers face, rather than the rate its cloud-investor-suppliers extended it. Bloomberg's report notes that OpenAI's own annualized run rate already tops $40 billion, though the two companies may not calculate the underlying metrics the same way, a reminder that quarter-to-quarter comparisons across labs are harder to make than the headline numbers suggest.
What Has to Happen Before Autumn
A confidential filing is not a prospectus, and Morgan Stanley, Goldman Sachs and JPMorgan Chase still have to turn investor-facing projections into audited financial statements that a public listing requires. That process is exactly where informal, sales-oriented numbers meet accounting rules, and it is common for the two to diverge, sometimes by a little and sometimes by a lot.
Anthropic filed in the same week as OpenAI, and the coincidence sets up a natural comparison the market will draw whether either company wants it or not: two frontier labs, both claiming a path to profitability, both leaning on cloud-provider relationships that mix vendor and investor in ways a public-market income statement has never had to disclose before. Whichever prospectus lands first will set the template the other is measured against.
