Summary
Anthropic's revenue growth slowed sharply in the third quarter, and the AI company flagged new risks to the computing capacity underpinning its expansion, adding to investor concerns ahead of its planned IPO. According to an amended S-1 filing submitted on Monday, revenue rose 47% from the prior quarter to $16.96 billion, down from a 144% increase in the second quarter. The company's net loss narrowed to $23.29 billion from $66.3 billion in the previous quarter, though it reported an operating loss of $567 million in Q3 compared with operating income of $974 million in Q2. Anthropic attributed part of the margin pressure to $5 billion in additional compute costs incurred during the quarter, which reduced revenue per dollar of compute from the prior quarter. The company's net loss also includes non-operating items tied to bonds convertible into its shares, per Reuters.
The filing highlights a dependency on external financing. Anthropic has nearly $900 billion in computing commitments with partners including Amazon and Alphabet's Google, and it expects to incur about half of the $895.4 billion in AI infrastructure spending commitments before December 31, 2030. Anthropic cautioned that certain compute providers and infrastructure partners rely on third-party financing or credit support to acquire chips and build capacity, and that if such support becomes unavailable or more expensive, contracted capacity may be delayed, repriced, reduced, or not delivered. The warning comes as record borrowing for data centers and chips has widened technology bond spreads and pushed issuers to offer higher premiums.
Customer growth remained strong, with more than 11,900 customers generating at least $100,000 in trailing 12-month revenue as of September 30, up from more than 1,500 at the end of 2025. Anthropic is preparing to begin formally marketing shares next week, and some investors are weighing a $1.5 trillion valuation, down from roughly $2 trillion, after the company disclosed financial details at a recent investor event, Reuters has reported. Renaissance Capital's Matt Kennedy said he did not view the results as worrisome but expected growth and margin pressure to be reflected in the eventual IPO valuation. Separately, Anthropic said it was considering tighter human oversight of some research and development decisions as its AI models take on a growing share of that work.
