Anthropic's S-1: $16.3B Revenue and a $637B Compute Bill
Anthropic filed its S-1 for a Nasdaq listing as ANT. Inside the $16.3B half-year revenue, the $80.7B accounting loss, 80% usage revenue and $637B of compute deals.
Anthropic Files S-1 for a Nasdaq Listing Under the Ticker ANT
On October 26, 2026, Anthropic, PBC filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission for a proposed initial public offering. The company intends to list its Class A common stock on the Nasdaq Global Select Market under the symbol ANT. The number of shares and the price range are still blank, and the registration statement has not yet become effective.
The announcement is about stock, not about Claude's features or pricing. What matters for anyone who uses these tools daily is what the filing reveals about how the company earns money, where it spends it, and how those numbers map onto the plans and limits you actually pay for. Here are the figures, straight from the document and from reporting on it.
The headline numbers: $16.3B revenue, $80.7B net loss
For the six months ended June 30, 2026 (unaudited), the S-1 reports:
- Revenue: $16.286 billion, versus $1.163 billion in the first half of 2025 — roughly 14x growth
- Full-year 2025 revenue: $4.585 billion (2024: $386 million; 2023: $41 million)
- Second-quarter revenue: $11.6 billion, with the company's first quarterly operating profit of $974 million
- First-half operating loss: $693 million
- First-half net loss: $80.748 billion
- Computing and infrastructure spend: $8.945 billion, up from $2.334 billion
- Cash and equivalents on June 30: $112.4 billion; short-term investments: $19.3 billion
- Total capital raised to date: $141.1 billion
The $80.7 billion net loss is mostly an accounting item, not cash out the door. The filing attributes $72.4 billion of it to changes in the fair value of convertible notes, derivative liabilities and SAFEs, driven by the rise in Anthropic's own enterprise valuation. Another $8.8 billion relates to note purchase agreements with Google and Amazon. On the company's adjusted (non-GAAP) basis, operating income was $1.618 billion — a margin of roughly 8 to 10%.
That distinction is the one most coverage gets wrong. Anthropic is neither an $80 billion loss-making enterprise nor a comfortably profitable one. It is a company with $16.3 billion of half-year revenue, a sub-$700 million operating loss, and one quarter of operating profit behind it.
Eight of every ten dollars come from usage, not subscriptions
The revenue mix is the most useful part of the filing for product people. Of the $16.3 billion booked in the half, $13.1 billion (80%) was consumption-based and $3.2 billion (20%) was subscription-based. More than 11,900 customers now spend $100,000 or more per year on a trailing-twelve-month basis as of September 30, 2026. Anthropic has about 5,300 employees.
In plain terms: the Pro and Max plans are the on-ramp, and token consumption on the API is the business. That structure explains a pattern many users already noticed — new capability tends to land on the API first, while plan-level limits and allowances get adjusted far more often on the consumer side. The October 21 API version 2026-10-21, Anthropic's first named API version since 2023, is the clearest recent example.
The $637 billion compute book
The heaviest section of the filing is the compute commitments. Adding up the named agreements listed in the S-1 gives a total of roughly $637 billion (the filing does not state an aggregate; this is arithmetic on the disclosed contracts):
- Broadcom: approximately $161.2 billion, starting 2026
- SpaceXAI: up to $120.5 billion, 2026–2029 (cancellable on 90 days' notice after initial periods ending January and March 2027)
- Google: at least $114.5 billion, 2026–2033
- Amazon: at least $110.0 billion, 2026–2036
- Microsoft: at least $44.9 billion, 2026–2033
- Nscale: up to about $44.6 billion, through 2033
- Lambda: approximately $41.3 billion, through 2034
The Google, Amazon, Microsoft and Broadcom agreements are described as non-cancelable and payable regardless of usage; several carry true-up clauses. Add separate TPU capacity commitments and deals still under negotiation, and reporting from the WSJ and The Register puts the potential total somewhere between $750 billion and $807 billion.
The demand side is far less locked in. Anthropic says much of its revenue carries no long-term commitment, and customers can reduce usage or walk away with little or no notice. Remaining performance obligations were about $10.8 billion as of June 2026, 75% of which will be recognized within a year, while the compute payments stretch seven to ten years. The filing itself warns that new capacity coming online can compress margins when it arrives ahead of demand — and admits the company has underestimated its compute needs before.
Why this matters if you pay for Claude
There is no shiny model launch here, but three practical implications follow from the numbers.
What the filing does not say
The S-1 contains no valuation and no offering price; the share-count and price-range fields are blank. Figures of $1.5 trillion to $2 trillion, a listing in the week of November 16, and a raise of $100 billion or more come from reporting by the Wall Street Journal and Reuters citing people familiar with the matter. Anthropic has not confirmed any of them. The last private round was a $65 billion raise in May 2026 at a $965 billion valuation.
For calibration: at $1.5 trillion, the listing would price the business at roughly 46x annualized first-half revenue ($32.6 billion). If the FT's report of $16.8 billion in third-quarter revenue holds, annualizing the most recent quarter brings the multiple down to about 22x. Same company, two very different-looking numbers, depending on whether you annualize a hypergrowth half-year or the latest quarter.
For tool buyers, the useful takeaway is not the ticker. It is that Anthropic's growth depends on keeping token demand high while paying for capacity it has already reserved. Watch the plan limits and the API price sheet, not the opening price.
