- Almost a quarter of 2025 revenue came from two customers: Cursor and GitHub Copilot.
Anthropic's IPO prospectus discloses a net loss of $42 billion for 2025 on revenue of $4.6 billion. Reuters and the Financial Times each reviewed the document. The company is pressing ahead anyway with a listing it wants valued above $2 trillion.
What the filing shows
Revenue reached $4.6 billion in 2025, twelve times the prior year's figure. The operating loss widened from roughly $3 billion in 2024 to more than $8 billion in 2025. Compute and infrastructure alone absorbed $7.33 billion last year.
That leaves a wide gap between the $8 billion operating loss and the $42 billion bottom line. Neither report explains what accounts for the difference, and no single line item is identified. Until the prospectus is public, the composition of that loss should be treated as unknown rather than attributed to a cause.
A $518 billion compute bill
The filing sets out $518 billion in commitments for cloud capacity, computing power and infrastructure in the years ahead. That is more than a hundred times 2025 revenue. Neither report gives a date by which the company expects to turn a profit.
Customer concentration
Almost a quarter of 2025 revenue traces back to two customers: the coding tool Cursor and Microsoft's GitHub Copilot. Both are products that can route requests to rival models. For a prospective investor, that makes a quarter of the revenue base contingent on two routing decisions made elsewhere.
A third of the pages are risk factors
About a third of the prospectus is given over to risk factors, covering manipulation, extortion and unpredictable model behavior. One passage states that the technology could pose existential risks to humanity. Risk sections are mandatory in a filing; a vendor describing its own product in those terms is not routine.
Timing and venue still open
Anthropic is targeting $100 billion in proceeds and a valuation above $2 trillion. No exchange and no date appear in either report. Media accounts say the listing has slipped to after the US midterm elections while the company negotiates a multibillion-dollar credit facility, neither of which has been officially confirmed.
