- Anthropic, the maker of Claude, had $17.0 billion in sales from July to September.
- That is about 12 times more than a year earlier.
- It has promised to pay about $895.4 billion, almost all for computing power.
- The price of its shares is not set yet.
- Prospectus
- The official document a company must publish before it sells its shares to the public.
- Net loss
- What is left when all costs, including accounting changes, are bigger than the money a company earns.
- Convertible note
- A loan that can later turn into shares. Its value rises when the company’s value rises.
Anthropic made its stock market prospectus public on October 26, with results up to the end of June. The amended version, filed on Monday, adds the third quarter of 2026 and new details about its compute bill.
Revenue keeps growing
Revenue was $16.96 billion in the three months to September 30, up from $11.56 billion in the second quarter. A year earlier it was $1.38 billion, so the quarter brought about 12 times as much.
Growth from one quarter to the next slowed to about 47%, from 144% in the second quarter, CNBC calculates. In the first nine months of 2026, revenue was $33.24 billion.
Figures for July to September 2026 from the amended prospectus of November 2.
A loss, mostly on paper
The net loss for the quarter was $23.29 billion, down from $66.31 billion in the second quarter. A year earlier, the quarterly loss was $12.14 billion.
Of the new loss, $21.94 billion came from a higher value of Anthropic’s convertible notes and similar contracts. The filing says this was mainly driven by the rise in the company’s own valuation. It is an accounting change, not cash spent.
The operating loss was $567 million, after an operating profit of $974 million in the second quarter. Anthropic blames $5.0 billion of compute bought under short-term deals, which costs much more than compute under multi-year deals. It also names $2.0 billion of non-cash charges for its donation matching programme.
Promises worth $895.4 billion
The filing lists purchase commitments and lease agreements worth about $895.4 billion, “substantially all of which is related to compute and infrastructure”, as of and after September 30.
About $447.5 billion of that is expected before the end of 2030, and most of the rest between 2031 and 2045. About $69.8 billion is due in the 12 months after September 30.
Compute and infrastructure cost $9.86 billion in the third quarter, up from $5.56 billion in the second.
What is still missing
The prospectus still leaves the share price range blank. Reports say the number of shares and the size of the offering are not set either.
Anthropic has applied to list on the Nasdaq as “ANT”, as its first filing already said. The shares will also be offered to the public in Australia, Canada, Japan, Switzerland, the UK and some other European countries, without a listing there.
