Anthropic Amends IPO Prospectus With Q3 Financials

Anthropic filed an amended Form S-1 with the Securities and Exchange Commission on Monday, adding third-quarter financials to its IPO prospectus. The company reported $33.24 billion in revenue for the nine months ended Sept. 30, up roughly 1,200% from the same period a year earlier, and a $104 billion net loss for the period. The initial prospectus, released last week, included financials only through the first half of the year.

Third-quarter results

During the third quarter, Anthropic generated roughly $17 billion in revenue, up about 1,127% from the same period last year. Third-quarter revenue increased around 47%, a steep drop from 144% growth in Q2 and 132% in Q1. The company reported a net loss of $23.29 billion during the third quarter. For the nine months of 2025, its loss was $25.1 billion.

Compute and infrastructure

In the amended filing, Anthropic said it has entered into purchase commitments and lease agreements with an aggregate committed spend of about $895.4 billion, substantially all of which is related to compute and infrastructure. Its compute and infrastructure expenses increased by $14.4 billion for the nine months ended Sept. 30, up 329% compared with the same period last year. "As our compute and infrastructure capacity grows, the associated compute and infrastructure expenses have increased," Anthropic said in the filing.

Market context

As the 5-year-old company prepares to kick off its roadshow, it will have to reckon with growing market jitters around the AI buildout. Wall Street has been worried that rising interest rates will make debt unaffordable for many data center developers and neoclouds, and quarterly reports from Microsoft, Alphabet and Amazon last week added fuel to those concerns. The hyperscalers' aggressive AI spending is eating into their cash flows, causing some investors to worry that computing capacity may not come online quickly enough to meet Anthropic's demands. Anthropic gets much of its capacity from Amazon, Google and SpaceX, but it also relies on neoclouds for some compute as it races to expand as quickly as possible.

Risk factors and rivals

Anthropic has worked to position itself as more safety-conscious than its competitors, and its S-1 includes more than 90 pages of risk factors. The company highlights risks, including potential political headwinds, its complex infrastructure needs, and the difficulties that can come from balancing safety and commercial objectives. "We consider it our personal responsibility to help the world understand these risks, to prevent or mitigate them when they arise from our AI models, and to work with governments and the rest of the industry to address them at a societal level," Anthropic's co-founders said in the filing. The company's CEO, Dario Amodei, co-founded Anthropic alongside a handful of other researchers who defected from OpenAI, now its chief rival. OpenAI confidentially filed its prospectus with the SEC in June, but its executives have signaled that it's aiming for a 2027 debut.
