Anthropic generated $17 billion in revenue in Q3 2026, up from $11.6 billion in the previous quarter.
But it recorded an operating loss of $567 million.
The company shared its July to September financials in updated filings ahead of its planned IPO.
Revenue increased more than 12 times from approximately $1.4 billion year-on-year, but performance reversed from a $974 million profit in Q2 to a loss in Q3
Anthropic attributed the latest quarter’s operating loss partly to its reliance on short-term computing capacity.
The company incurred $5 billion in expenses for short-term computing during Q3, which it said costs significantly more than capacity secured through multi-year agreements.
It also recorded $2 billion in non-cash expenses related to its employee share-donation matching programme.
The company’s amended filing also disclosed $33.2 billion in revenue for the first nine months of 2026, compared with $2.5 billion in the same period last year.
Its operating loss for the nine months stood at $1.26 billion.
Its net loss reached $104 billion, including a $94.3 billion non-cash charge reflecting changes in the fair value of convertible notes, derivative liabilities, and other financing instruments.
Anthropic filed its initial registration statement with the US Securities and Exchange Commission on October 26.
The filing also disclosed approximately $895.4 billion in committed spending on computing and infrastructure.
Of this, around $447.5 billion is expected to fall due before the end of 2030, including $69.8 billion in the 12 months following September 30, 2026.
These commitments reflect the long-term contracts Anthropic uses to secure computing capacity for model training and inference.
Anthropic reported more than 11,900 customers generating at least $100,000 in revenue over the preceding 12 months as of September 30, up from more than 950 a year earlier.
The company said successive model releases and increased usage contributed to revenue growth.
However, price reductions on newer models and contractual discounts reduced revenue by about $600 million between Q2 and Q3.
