Anthropic reports $16.96B in third-quarter revenue in amended IPO filing

Anthropic filed Amendment No. 1 to its Form S-1 registration statement (Registration No. 333-299633) with the US Securities and Exchange Commission on 2 November 2026, adding financial results through 30 September 2026. Third-quarter revenue reached $16,956 million, up 47% sequentially from $11,555 million in Q2 2026 and 1,127% above Q3 2025’s $1,382 million. Nine-month 2026 revenue totalled $33,242 million, with 79% ($26.3 billion) coming from consumption-based API and cloud usage.

Compute and infrastructure costs rose 382% year on year to $9,863 million in Q3, pushing GAAP operating results to a $567 million loss after $5.0 billion in higher-cost short-term compute capacity and $2.0 billion in non-cash donation-matching charges. Excluding share-based and non-cash items, non-GAAP Adjusted Operating Income was $2,463 million (a 15% margin), while GAAP net loss reached $23,291 million after a $21,936 million non-cash fair-value remeasurement on convertible notes and SAFEs. Anthropic ended September with $95.6 billion in cash and $36.3 billion in marketable securities, and left its IPO share count and price range blank.
