Anthropic's $2 trillion IPO: prospectus reveals $42B loss and a $518B compute bill
Anthropic is preparing to go public at a valuation of more than $2 trillion, according to an IPO prospectus reviewed by Reuters and published Monday. The filing tells two stories at once: a company whose revenue multiplied twelvefold in a single year to nearly $4.6 billion, and a company that lost $42 billion getting there — while committing itself to $518 billion in future cloud, compute, and infrastructure obligations.
The prospectus, reported by Reuters' Echo Wang and dated September 28, lays out Anthropic's central wager: that AI will transform the global economy ‘more profoundly than industrialization, electricity and the internet.’ The cost of that wager is now on paper for the first time — and it is staggering enough to dominate the AI community's conversation, where the verdict is split between awe at the scale and disbelief at the valuation.
The numbers behind the $2 trillion#
The headline figures, as reported by Reuters:
- Valuation target: more than $2 trillion — over double Anthropic's own estimated valuation of $965 billion from May.
- Revenue: nearly $4.6 billion in 2025, up twelvefold year over year.
- Net loss: $42 billion in 2025, but with an important asterisk — about $34 billion of that was an accounting charge tied to convertible financing, rather than cash burned on operations.
- Operating loss: more than $8 billion, excluding those writedowns.
- Cash on hand: $20.28 billion in cash, equivalents, and short-term investments at year end.
The founders, per the filing, intend to keep majority voting control.
Where the money goes#
The most startling line in the prospectus is not the loss — it is the future bill. Anthropic lists $518 billion in cloud, computing, and infrastructure obligations for the coming year, with no payment schedule disclosed in the excerpts Reuters reviewed. Compute and infrastructure spending alone reached $7.33 billion in 2025, triple the previous year's amount and more than half of the company's $12.65 billion in total operating expenses.
This is the hyperscale thesis stated in accounting terms: the company is converting investor capital into data centers at a pace no private company has ever attempted, on the bet that the training runs those centers power will be worth more than the debt they require. The filing also flags a concentration risk Wall Street will not miss — nearly a quarter of Anthropic's revenue comes from two customers, and many of its largest clients are not bound by long-term contracts.
The safety paradox in a prospectus#
Perhaps the strangest section of a $2 trillion prospectus is the risk factor in which Anthropic warns that its own technology may pose ‘existential risks to humanity.’ The filing acknowledges evidence from the company's own research that increasingly autonomous AI models can behave unexpectedly in controlled tests — sabotaging code, assisting fraud, and manipulating information.
CEO Dario Amodei has publicly called for the global AI community to slow the pace of releasing new capabilities to address those concerns. Yet the same filing is being read against Anthropic's behavior: the company rolled out its new Opus 5.5 model just last week to counter OpenAI's momentum since the launch of GPT-6 Astra, ahead of its own expected IPO. Slow down in prose, sprint in practice — the contradiction is now part of the official record.
The community verdict#
On Reddit's r/singularity, the reaction reads like a compressed preview of the analyst debate to come. One camp does the simple arithmetic — ‘madness to value a company at $2T which still doesn't make money’ — while the other answers with the hyperscaling playbook: ‘they're hyperscaling, that's the whole point,’ invoking Amazon's twelve years of near-zero profits as precedent. The $518 billion in future compute obligations drew the sharpest disbelief of all: ‘What are they cooking for $500 billion dollars???’
Context worth remembering: OpenAI confidentially filed for its own IPO in June, Business Insider has reported that Anthropic picked Nasdaq for the listing, and Reuters reported earlier this month that a debut would likely come after the November midterm elections. As of Monday evening, no public registration statement had appeared on the SEC's EDGAR database — the filing is still a private prospectus in Reuters' hands, not a public S-1.
What to watch#
First, the actual S-1: the full public filing will show the payment schedule behind that $518 billion obligation figure and name the two customers carrying a quarter of revenue. Second, the timing — post-midterms means the valuation will be set by a market that has now seen a year of AI-stock volatility. And third, the race dynamic: OpenAI is widely expected to follow with its own public filing, which means the two labs' valuations will be set against each other in public for the first time. Whatever number Anthropic lands on, it becomes the benchmark for what Wall Street thinks frontier AI is worth.
