Anthropic revenue hits $4.6bn but losses swell to $8.06bn as it prepares for public listing
Anthropic has filed its S-1 prospectus with the US Securities and Exchange Commission, revealing a dramatic rise in income alongside a steep increase in operating losses. The company expects to list its shares in November, with backers targeting a market value exceeding $2 trillion.
The filing warns that the technology it builds carries “existential risks to humanity.” According to reports from the Financial Times and Reuters, the document lists dangers such as manipulation and blackmail as potential outcomes of increasingly advanced AI models.
Financials show soaring costs
Revenue grew twelvefold in 2025 to reach nearly $4.6 billion. Despite this growth, the operating loss expanded from $2.98 billion in the previous year to $8.06 billion. A significant portion of that loss stems from spending on compute and infrastructure, which totalled $7.33 billion.
That infrastructure spend is three times the figure from the prior year and accounts for more than half of total operating costs. The bulk of the roughly $42 billion net loss over the period comes from an accounting charge rather than cash expenditure. This charge reflects the higher estimated value of financing that might eventually convert into stock.
The business relies heavily on a small number of clients. Just two customers generated nearly a quarter of revenue in 2025. The filing notes that many large clients are not bound by long-term contracts, creating a degree of instability.
Looking ahead, Anthropic plans to commit $518 billion to cloud, compute, and infrastructure over the coming years. The prospectus states the company expects AI to reshape the global economy more profoundly than industrialisation, electricity, or the internet did. In the second quarter of 2026, the firm reported $11.5 billion in revenue and is on track for a second consecutive quarter of operating profit on an adjusted basis.
Valuation targets and industry impact
Investors believe a valuation above $2 trillion is achievable. This would double the $965 billion figure recorded in May and surpass the roughly $1.8 trillion SpaceX was worth when it went public in June.
Analysts expect the first artificial intelligence company to list on the stock market to set valuation benchmarks for the entire sector. Rival OpenAI filed for an IPO confidentially in June, though Anthropic’s debut is likely to wait until after the US midterm elections.
What it means
For the people building and using these systems, the financial pressure is immense. The company is pouring hundreds of billions into hardware and cloud capacity while trying to prove it can turn that spend into profit. This means developers and customers face a future where access to the most capable models depends on a public market that has not yet opened, with valuations and costs set to define the industry for years to come.
