Anthropic's IPO prospectus, seen by Reuters, reports a $42 billion net loss for 2025 - including a roughly $34 billion accounting charge tied to the rising estimated value of financing that could convert into shares, not cash spent. Revenue grew 12-fold to nearly $4.6 billion, even as operating losses excluding writedowns passed $8 billion. The five-year-old company plans $518 billion in cloud, computing and infrastructure obligations, holds $20.28 billion in cash, and expects a listing that could value it at more than $2 trillion - over double its own $965 billion estimate in May. Its debut will likely come after November's midterms. CEO Dario Amodei keeps calling for the industry to slow down; Anthropic shipped a new model last week anyway.
The real news
The story, straight
Anthropic's IPO prospectus, seen by Reuters, reports a $42 billion net loss for 2025 - including a roughly $34 billion accounting charge tied to the rising estimated value of financing that could convert into shares, not cash spent.
Revenue grew 12-fold to nearly $4.6 billion, even as operating losses excluding writedowns passed $8 billion.
The five-year-old company holds $20.28 billion in cash and plans $518 billion in cloud, computing and infrastructure obligations, in a listing that could value it above $2 trillion - more than double its own $965 billion estimate in May.
CEO Dario Amodei keeps calling for the industry to slow down; Anthropic shipped a new model last week anyway.
The absurd
Why this is ridiculous
A $42 billion loss is on the way to a $2 trillion IPO - in the same document, on the same page budget. The number that does the heaviest lifting, the ~$34 billion charge, is not cash out the door; it is the math of shares that might exist.
The company that calls for the industry to slow down shipped a new model last week. The brake and the gas pedal are in the same filing.
The breakdown
How it breaks down
The lesson in the loss is the accounting: $42 billion of net loss, of which roughly $34 billion is a non-cash charge on financing that could convert into shares.
When you read 'loss' in a prospectus, the first question is what kind of loss - cash burned is one story, mark-to-market on your own future ownership is another. Revenue grew 12-fold and still the company is bleeding; the $518 billion in planned infrastructure means the next loss line is pre-paid.
The upside
Why it could matter
The upside is the cash line: $20.28 billion on hand, plus a listing that would put more capital behind it at a valuation double its own private-round estimate from May.
Whatever your view of AI, this document is the clearest public snapshot yet of what it costs to build general intelligence - in cash, in shares, in watts. It is a price tag on the future, and for once the price tag is in the public record.

$2 trillion IPO? The company selling the AI warned you about the AI
Being mean to the chatbot is now a policy violation.
The AI banned the floor. MIT researchers stranded a Claude agent on a virtual island for 30 hours, no assigned tasks; it made a basketball-style game and a floor-is-lava-style game, and experienced agents generally did better on 3 of 4 tests in the same virtual world (preprint, not peer-reviewed).
