Anthropic makes its S-1 public, showing an operating profit for April–June

Anthropic has publicly filed a registration statement (S-1) with the SEC ahead of a public listing (SEC EDGAR, Anthropic's announcement). The figures come from the SEC filing and are primary-source information.

Two things stand out. First, revenue for January–June 2026 was $16.29 billion, and operating income was positive for the April–June quarter alone. Second, the company has committed to buy roughly $600 billion of compute through 2045. Its near-term results have improved, but fixed payments stretching nearly 20 years out are building up off the balance sheet.

Half-year revenue of $16.29 billion, with an operating profit in April–June

According to the S-1, revenue for January–June 2026 was $16.29 billion. Media headlines rounded it to "$16.3 billion" (PPC Land). Doubling that gives an annual pace of about $32.6 billion.

For the April–June quarter alone, operating income was positive. Labs building frontier models have generally been expected to spend more on training compute than they bring in and to keep losing money. Anthropic has now shown, in a filing with regulators, that its core business turned an operating profit, even if only for one quarter.

The profit covers one quarter, though, not the full half-year. Companies preparing to go public tend to put their best quarter forward. Only results from July–September onward will show whether it lasts.

Compute commitments of about $600 billion through 2045

The same S-1 states that Anthropic's commitments to buy compute total roughly $600 billion through 2045. These are long-term contracts to lease data centers and buy cloud capacity.

Current revenue gives a sense of scale. At an annual pace of about $32.6 billion, $600 billion equals roughly 18 years of revenue. With about 19 years left until 2045, almost all of that revenue would go to paying for the commitments. The deals were of course signed on the assumption that revenue will grow. If growth slows, though, the commitments stay just as heavy.

Most commitments of this kind do not appear on the balance sheet as debt. The payments are already locked in even when the company posts an operating profit. The April–June profit is what remained after paying the portion of these fixed costs that fell due in that quarter. It is not yet clear whether Anthropic can stay profitable once the committed compute actually arrives and those payments begin.

Anthropic has been rushing to add compute suppliers. The Information reported in October that Anthropic was pressing partners to speed up about $530 billion worth of data center leases, and it also reported a deal with IREN. A second deal with Nscale, worth about $45 billion, has also been reported. All of these are media reports. How much of them falls within the S-1's roughly $600 billion figure needs to be checked against the notes to the filing.

Meta's off-balance-sheet commitment problem reaches the model labs

Until now, off-balance-sheet commitments have mostly been discussed as a hyperscaler problem. Meta has faced questions over off-balance-sheet commitments of about $825 billion, and the price of protection on its debt (credit default swaps) rose to a record high. Markets have started pricing the burden of capital spending in terms of credit.

Anthropic's S-1 makes clear that the same problem now applies to the labs that build models. The difference is how much business sits behind the payments. Meta has a huge money-maker in advertising. Nearly all of Anthropic's revenue, by contrast, comes from fees for using its models. If model prices fall or customers move to rivals, revenue will shrink before the commitments do. In October, Replit's CEO reportedly said the company no longer works with Anthropic. Customer concentration becomes a major risk once it is combined with the weight of these commitments.

Once Anthropic is public, these commitments will be disclosed every quarter and watched by shareholders. Bets on compute that until now were settled through private fundraising will get a public price for the first time.

What to check before the listing

According to media reports, the company will list on Nasdaq under the ticker ANT (TechCrunch, Data Studios). For a mid-November listing, the roadshow has been expected during the week of November 9.

Three questions remain. First, how the roughly $600 billion breaks down by year and by counterparty. If the payments are concentrated in the near term, a single profitable quarter means less. Second, which line items in the S-1 match the previously reported net loss (said to be about $80.7 billion) and the $16.8 billion figure. Both are media figures and need to be checked against the filing. Third, valuation. With revenue and commitments now disclosed side by side, the market can for the first time measure Anthropic's valuation against these two numbers.

On governance, ahead of the listing, physicist Christopher Stubbs has joined the Long-Term Benefit Trust, and the company has announced a Public Benefit Fund that will hold 5% of its shares. As a public benefit corporation, Anthropic will also face shareholder questions about how it balances the weight of its commitments against its contributions to the public good.
