Anthropic’s growth slowed and costs jumped in the third quarter, updated IPO filing shows

Anthropic has filed an amended Form S-1 with the Securities and Exchange Commission, providing updated financial data for the third quarter of 2026. The filing reveals that quarterly revenue reached $17 billion, contributing to a nine-month total of $33.24 billion—a roughly 1,200% increase over the same period in 2025. While revenue grew 47% from the second quarter, this represents a deceleration from the 144% growth seen in the previous period. The company reported a net loss of $23.3 billion for the quarter and $104 billion for the nine-month period, largely attributed to the change in fair value of convertible notes. Additionally, Anthropic disclosed purchase commitments for computing and infrastructure totaling approximately $895.4 billion, with roughly $70 billion due by September 2027.
