Anthropic, the company behind Claude, reported $16.3 billion of revenue for the six months ended June 30, 2026, in the prospectus it filed with the Securities and Exchange Commission on October 26. The same filing reports a net loss of $80.7 billion for that period. Both numbers come from the same document, and they do not describe the same thing.
The revenue figure is the size of the business. The net loss figure is dominated by an accounting charge that did not take cash out of the company. Reading the two apart is the point of the filing, and it changes how the first half of 2026 looks.
Three numbers that look alike
The prospectus gives three different measures for the first half of 2026, and each answers a different question.
| Measure | First half of 2026 | First half of 2025 |
|---|---|---|
| Revenue | $16.3 billion | $1.2 billion |
| Operating loss, GAAP | $693 million | $2.1 billion |
| Net loss, GAAP | $80.7 billion | $13.0 billion |
| Adjusted operating income (loss), non-GAAP | $1.6 billion | ($1.8 billion) |
Figures are in billions, rounded from the filing. Interim figures are unaudited.
Revenue answers how much customers paid. The operating loss answers what running the business cost after operating expenses, before financing revaluations. The net loss answers what remains after those revaluations are included. Anthropic's own adjusted measure, which leaves out stock based pay and some other items, shows a $1.6 billion operating profit for the period, against a $1.8 billion adjusted loss a year earlier. That adjusted figure is the company's own choice of what to leave out, so it sits beside the GAAP operating loss rather than replacing it.
Why most of the net loss is paper
Of the $80.7 billion net loss, $72.4 billion is a change in the fair value of convertible notes, derivative liabilities, and SAFEs, according to the filing. In plain terms, Anthropic had taken money from investors through notes that convert into shares. As the company's valuation rose, those notes became more valuable on paper, and accounting rules record that increase as a loss.
No cash left the company for that charge. The cash flow statement tells a different story from the net loss line: operating activities provided $3.9 billion of cash in the first half of 2026, compared with $1.5 billion of cash used in the same period in 2025. A reader who stops at the $80.7 billion headline would miss both facts.
Where the revenue comes from
Most of the money arrives when customers use Claude, not when they subscribe. Consumption based revenue, which Anthropic calls pay-for-intelligence, was $13.1 billion, or 80% of total revenue, in the first half of 2026. Subscription revenue was $3.2 billion, or 20%.
The customer base behind those totals is concentrated at the top. At September 30, 2026, Anthropic counted more than 11,900 customers with $100,000 or more of revenue on a trailing twelve month basis, up from more than 950 a year earlier. More than 1,900 customers were at $1 million or more, and about 250 were at $10 million or more. That spread matters because a small number of large customers can move the total, and the prospectus says a substantial part of revenue depends on a limited number of customers and distribution channels.
What the cash pile has to cover
At June 30, 2026, Anthropic held $131.7 billion in cash, cash equivalents, and short-term investments. That pile looks large until it is set against the compute commitments the prospectus names:
- Google: at least about $114.5 billion, from April 2026 to July 2033, regardless of actual usage.
- Amazon: at least $110.0 billion, from May 2026 to April 2036, regardless of actual usage.
- Microsoft: at least $44.9 billion, from November 2026 to May 2033, regardless of actual usage.
Together, those three minimums add to $269.4 billion. Anthropic also estimates a further $125.0 billion to $150.0 billion for additional TPU compute to be delivered from 2028 to 2031, which is not included in its contractual commitments table. The prospectus says it expects to fund these investments through revenue and capital it raises, and it warns that it expects to keep entering into more arrangements to secure compute capacity.
Anthropic also gives its own reason for caution. The prospectus says recent growth may reflect early stage adoption and a young market, that it expects the revenue growth rate to decline over time, and that the decline may be significant and faster than it anticipates as the revenue base grows.
What is still blank
The filing does not set the number of shares, the price range, or the listing date. Anthropic has applied to list Class A shares on the Nasdaq Global Select Market under the symbol ANT, and its announcement says the registration statement has not yet become effective. Shares cannot be sold, and offers to buy cannot be accepted, until that happens. The next document to watch is an amended filing that fills in those blanks, because that is when the price argument starts.
