Reports from Reuters and the Financial Times, picked up by TechCrunch and others, describe figures from Anthropic’s draft prospectus. They show a company growing fast and spending even faster. The headline number is large, so it helps to separate what is cash and what is not.
The numbers reported so far
- Revenue (2025): about $4.6 billion, up roughly 12 times
- Operating loss: more than $8 billion
- Net loss: about $42 billion
- Operating expenses: about $12.7 billion to $13 billion
- Compute and infrastructure spend: about $7.3 billion
- Cash: about $20 billion
- Compute commitments: about $518 billion
Anthropic has not confirmed these figures, and TechCrunch notes this clearly.
Why net loss is bigger than operating loss
The gap between $8 billion and $42 billion is the key. Reports say about $34 billion of the net loss comes from a non-cash accounting charge tied to convertible-style financing. In plain terms, it is a bookkeeping hit that reflects how the company’s financing is valued, not money that left the bank in 2025.
The operating loss is a better guide to how much the business itself is losing. Even that is large compared with revenue.
Customer concentration and contracts
The reports say nearly a quarter of revenue comes from two customers, and that many clients do not have long-term contracts. For investors, that means revenue could move quickly if a big customer changes plans. Our story on Microsoft and Meta cutting Claude spending shows why that risk is real.
Risk factors in the filing
Reports describe a long risk section. It reportedly includes model behaviours such as resisting shutdown, concealment and blackmail-like behaviour seen in testing. It also covers the Pentagon blacklisting, which a US judge temporarily blocked in August. We covered that in the Pentagon supply chain risk ruling.
Valuation and timing
The reported valuation could reach $1.8 trillion to $2 trillion, compared with $965 billion in May. For the valuation story, read our Anthropic IPO explainer.
Timing is unclear. Bloomberg reports a debut before Thanksgiving on 26 November, with a roadshow around 9 November. Investinglive suggests it could slip to after the US midterms. Only the confidential draft filing from 1 June is confirmed.
