Anthropic plans to spend up to $567 billion on compute. Its IPO prospectus reveals plans to set up its own data centers

Anthropic’s 318-page IPO prospectus , which the company made public today, makes one thing clear: Compute is essential to Anthropic’s business, and not securing enough of it is a significant risk factor.

“Our ability to develop, train, improve, and deploy frontier models depends on our access to enormous and increasing quantities of specialized compute,” the company wrote in its prospectus, which is part of an S-1, a form the U.S. Securities and Exchange Commission requires companies to file ahead of an initial public stock offering. At the same time, “the market for compute is intensely competitive,” and Anthropic competes with “some of the world’s largest and most well-capitalized technology companies,” the document said.

The company’s future computing costs are potentially massive and could swamp Anthropic’s ability to pay for them. In total, the company has committed to spending between $542 billion and $567 billion on future compute and infrastructure, the S-1 reveals. On Dec. 31, 2025, Anthropic signed a $417 billion compute deal with various providers. The deals therein start between 2026 and 2027 and last for one to 20 years. Anthropic also signed up for more capacity, starting between 2028 and 2031, totaling $125 billion to $150 billion.

Overall, compute is Anthropic’s number one operating expense, costing it $5.6 billion in the second quarter of 2026. But for now, the company generates a healthy amount of revenue from that spending. The company made $11.6 billion in revenue during the same quarter. That means it’s in the black as far as its revenue-to-compute ratio, a metric the S-1 says the company is focused on continuing to improve. It made a little over two dollars for every dollar it spent on compute.

Anthropic did not immediately respond to requests for comment on this story.

Anthropic is securing compute from three main cloud service suppliers: Amazon , Google, and Microsoft . The S-1 also reveals deals with Elon Musk–owned SpaceX. From May to October 2026, Anthropic entered into a series of deals with SpaceX to access up to $120.5 billion in compute through 2029. (That compute is powered by Nvidia GPUs SpaceX owns.)

The company has also built a “proprietary orchestration layer” that optimizes which workloads it runs on different chips across the different cloud providers, including AWS Trainium, Google TPUs, Nvidia GPUs, and AMD GPUs. This intelligent router of sorts took Anthropic “years of significant investment to build,” the company says. It helps Anthropic keep costs down, and reduces dependence on any one supplier.

The problem is, Anthropic’s relationship with Amazon, Google, and Microsoft is “multifaceted and complex,” the S-1 says. These suppliers are also its competitors, who need compute for their own AI products, so they could “prioritize their own compute needs.” The companies may also “gain insight” into how Anthropic’s business runs, and its compute requirements, that “could inform their competitive strategies.” Adding even more wrinkles to these circular relationships, Microsoft, Amazon, and Google have all made “significant” investments in Anthropic, and may continue to do so in the future. The kicker: They’re also customers of Anthropic’s products, using its models.
