Space X IPO Filing Reveals Anthropic Is Paying $15 Billion a Year to Access Its Data Centers

Anthropic has agreed to pay Space X

Details

Anthropic and Space X announced a deal earlier this month that gives the Claude developer access to GPUs at Colossus and Colossus II, a pair of data centers straddling Tennessee and Mississippi with more than one gigawatt of computing power. Space X had rushed to build the facilities for its x AI unit, which develops the Grok AI chatbot, but Musk said his company didn’t need all of their computing capacity in the end. Terms of the deal had not been previously disclosed.

Anthropic is paying an unspecified reduced fee for May and June before the $1.25 billion per month rate takes effect, Space X said in its S-1 regulatory filing.

The eye-popping figure is a sign of how hungry Anthropic is for computing resources needed to power products like its increasingly popular AI coding tools. The company’s revenue for the second quarter of 2026 is expected to exceed $10 billion, according to the Wall Street Journal.

An Anthropic spokesperson confirmed the figures to WIRED. Space X did not immediately respond to WIRED’s request for comment.

Space X says it expects to “enter into additional similar services contracts” around its compute infrastructure and will continue using its data centers for itself. “We have sufficient capacity to provide compute for our own AI models, including support of our training and inference demands, and to satisfy the obligations under these agreements,” the filing states. “We believe our dual monetization strategy provides multiple pathways to generate returns on invested capital.”

The filing details Space X’s business opportunities and risks ahead of an initial public offering. Space X is pursuing the largest IPO in history, with hopes of raising about

The S-1 is meant to help potential investors better understand the company and the challenges it faces. One widespread concern is the amount of power Musk holds over Space X and whether there are enough safeguards to hold the cofounder and CEO in check.

Excerpts of the IPO filing seen by Reuters before it was published showed that the only person who can fire Musk is the billionaire himself. The documents also revealed that he will be able to maintain control of the company’s board. In addition, he and his allies will have outsized voting power, allowing them to beat back attempts by activist shareholders to derail company endeavors. Space X also plans to exercise provisions of Texas law to fend off hostile takeovers and the removal of executives or board members.

In recent weeks, advocacy groups including a leading US teachers’ union, AI safety researchers, and environmental organizations operating near Space X facilities have called on investors to think twice before buying shares in the company. The activists have written to investors and Space X urging them to reconsider support for an approach that consolidates power with Musk. The heads of public employee retirement funds for California, New York, and New York City jointly called Space X’s proposal “novel and extreme” and the “the most management-favorable governance structure ever brought to the U. S. public markets at this scale.”

“We acknowledge Space X’s extraordinary technical and commercial achievements, and we recognize the role the company plays in U. S. national security and commercial space,” the pension fund leaders wrote to Musk and his fellow executives. “Its governance must at least adhere to the baseline protections upon which long-term institutional capital depends, rather than seeking to diminish them.”

They and other activists are also concerned about Space X’s reported intentions to let individual investors buy an unusually large slice, or about 30 percent, of initially offered shares, which could help turn the company into a risky meme stock with wildly fluctuating prices. However, unless there are major hiccups with the IPO, Space X will quickly benefit from new stock market rules that will require certain popular investment funds to buy up its shares and hold onto them, potentially both boosting and stabilizing prices.

Leaks from confidential versions of the S-1 are rare, but Space X has experienced a bunch of them beyond the governance details. Reporting from the Information revealed sales from Starlink, Space X’s satellite internet service, reached about

Other leaks described x AI potentially being banned in certain countries for its chatbot generating sexually abusive imagery, plans to spend a substantial amount of money manufacturing GPUs, and uncertainty about orbiting data centers in space working out as a business.
