Key Highlights

  • Anthropic's first-half net loss reached USD 80.7 billion, up from USD 13 billion a year earlier.
  • A USD 72 billion revaluation of convertible bonds accounts for nearly nine-tenths of the loss and involves no cash outlay.
  • Third-quarter revenue of USD 16.8 billion rose 45% on the second quarter, after growth of more than 100% before.
  • Computing and infrastructure spending climbed to nearly USD 9 billion in six months, almost four times the prior-year figure.

The Loss Is Large, but Most of It Is a Paper Charge

The headline figure in Anthropic's draft prospectus is stark: a net loss of USD 80.7 billion for the first six months of 2026, against USD 13 billion in the same period a year earlier. The document attributes USD 72 billion of that to a revaluation of bonds that can convert into company shares. As the estimated value of the shares rises, so does the liability, and the change is booked as a loss even though no money leaves the company.

Strip that charge out and the remaining loss is about USD 8.7 billion, a figure derived from the two numbers in the filing. The company posted the same pattern in 2025, when it reported a net loss of USD 42 billion, most of it from a similar charge, and an operating loss of about USD 8.1 billion on USD 4.6 billion of revenue.

Spending Is the Real Pressure Point

The filing shows what the business costs to run. Anthropic spent nearly USD 9 billion on computing capacity and infrastructure in the half-year, compared with USD 2.3 billion a year before. It has also committed to spend at least USD 518 billion over ten years on cloud services, computing and related infrastructure.

Computing outlay therefore grew about 3.9 times in a year, a ratio computed from the two figures. Those commitments are the main reason investors are asking whether the money going into chips and data centers across the industry earns enough back.

Revenue Is Rising, but the Pace Has Cooled

At an investor meeting on October 14, the company told prospective buyers that third-quarter revenue reached USD 16.8 billion, up 45% from USD 11.6 billion in the second quarter. That is still fast, but the second quarter had more than doubled from the first, so the sequential growth rate has dropped by more than half. Some investors were disappointed by the slowdown, though the numbers eased some concerns about costs.

Claude Code, the company's coding assistant, has been a significant contributor to demand among software developers.

Valuation and Market Stakes

Anthropic is planning to list in November. Some investors are weighing a lower valuation of around USD 1.5 trillion after the latest disclosures, according to a report last week. The listing matters beyond one company: investors see the near-term outlook for AI-related stocks as tied closely to how the offering is received, with rival OpenAI's possible listing next year coming after it.

The company is based in San Francisco and did not respond to a request for comment on the filing.
