Anthropic’s Prospectus Asks for a $2 Trillion Story on a $42 Billion 2025 Loss
Reuters says it has seen Anthropic’s IPO prospectus: 2025 revenue near $4.6 billion, an operating loss above $8 billion, and a roughly $42 billion net loss driven mostly by a non-cash financing charge. Forward cloud and compute obligations of $518 billion sit against $20.28 billion of cash. Anthropic declined comment. The document is not public.
The number that will travel is a valuation above $2 trillion. The number that explains the business is a 2025 net loss of about $42 billion, most of it an accounting mark on financing that might become stock — not cash spent running Claude. Reuters says both figures are in an IPO prospectus it has seen. Anthropic declined to comment. This is not a public S-1 exhibit you can download.
That is the trade for anyone treating Anthropic as the safety lab that is ready for Nasdaq. The prospectus, as Reuters describes it, is a scale story — AI transforming the economy more than industrialization, electricity, and the internet — financed by obligations the year-end cash balance does not cover.
What Reuters says is in the document
CNBC carried the Reuters account, first published the evening of September 28. Every figure below is Reuters reporting from documents it says it saw, not a Times of AI reading of a filing.
| Item (2025, as reported) | Figure |
|---|---|
| Revenue | nearly $4.6 billion, about 12× the prior year |
| Operating loss | more than $8 billion, excluding writedowns tied mostly to prior fundraising |
| Net loss | about $42 billion |
| Of which, financing fair-value charge | roughly $34 billion — value of financing that could become shares, not operating spend |
| Compute and infrastructure | $7.33 billion, about triple 2024, and more than half of $12.65 billion operating expenses |
| Cash, equivalents, and short-term investments | $20.28 billion at December 31 |
| Planned cloud, compute, and infrastructure obligations | $518 billion in coming years |
Customer concentration is in the risk factors Reuters describes: nearly a quarter of revenue from two customers, and many large clients not on long-term contracts.
The expected public sale could value Anthropic above $2 trillion, more than double a $965 billion figure Reuters says was the company’s own estimate in May. On timing, Reuters has previously reported the debut is likely after the November US midterms. That is a source-attributed expectation, not a priced deal or a date the company has confirmed.
It also sits awkwardly next to nearer-term reporting. Times of AI’s September 13 note covered Business Insider and Reuters on a potential October Nasdaq listing, and on an investor message of a second straight quarter of adjusted operating profit on $11.5 billion of Q2 revenue. A 2025 GAAP net loss dominated by a fair-value charge is a different statement from a 2026 adjusted-profit claim. Both can be in the record. Neither is a cleared IPO.
What this does not settle
The confidential draft is older in sequence: a draft S-1 in June, then reporting on founder super-voting stock. This week’s increment is the first widely circulated look at full-year economics and the size of the infrastructure promise. Amazon and Google remain, in Reuters’ telling, early strategic investors and cloud suppliers. The same story notes OpenAI’s confidential IPO filing and media expectations of a listing by early 2027. That is context, not a term sheet.
Dario Amodei has argued for slowing capability releases. Reuters points out the company still shipped Claude Opus 5.5 the week before, into a race with GPT-6 Astra, while preparing to sell the equity story. The prospectus does not resolve that tension. It prices the spending required to stay in it.
Limits
- Wire of a document: “seen by Reuters.” No public prospectus, no SEC URL, no Anthropic confirmation. CNBC and Yahoo Finance are the same Reuters file, not a second leak.
- The $2 trillion figure and the post-midterms timing are described as expected or previously reported, not as an offering price or a filed date.
- The $34 billion charge is an accounting fair-value item. Do not add it to cash burn. The operating loss above $8 billion is the closer operating figure, and it is still Reuters’ paraphrase.
- The Q2 2026 adjusted-profit claim lives in prior coverage. It is not restated from this prospectus story.
