# Anthropic is paying $15 billion a year for access to Elon Musk’s data centers

Earlier this month, SpaceX and Anthropic[announced a new compute partnership](https://x.ai/news/anthropic-compute-partnership)that provides access to the rocket company’s Colossus data centers in Memphis, TN\. Now, with the release of[SpaceX’s IPO filing](https://www.theverge.com/science/935102/spacex-ipo-elon-musk-tesla-cybertruck-xai-risk-factor), we have more details about that deal, including how much Anthropic is paying to Elon Musk’s company\.
In its S\-1 filing, SpaceX said that Anthropic agreed to pay $1\.25 billion per month through May 2029 for access to SpaceX’s AI training centers at Colossus I and Colossus II\. That’s $15 billion annually, or nearly double the $18\.7 billion in revenue that SpaceX reported in all of 2025\.
The agreement includes a clause in which either company can terminate the deal within 90 days\. And Anthropic’s fees will be reduced during the capacity ramp\-up this month and next\.
The exit clause was likely necessary based on the fast\-moving nature of the AI industry\. In some sense, Anthropic’s Claude competes with X’s Grok\. And it’s a sign of how desperate AI companies like Anthropic are for[compute capacity](https://www.theverge.com/ai-artificial-intelligence/902546/data-centers-ai-energy-power-grids-controversy), especially as the data center build out across the country runs into[serious local opposition](https://www.theverge.com/ai-artificial-intelligence/930477/ai-data-centers-gallup-survey-70-percent-opposition)\.
In a post on X, Musk said that SpaceX stands ready to offer similar deals to other AI companies that want to access the data centers\. SpaceX is “offering AI compute as a service at significant scale,” he said\.
SpaceX has been spending enormous amounts of money on AI since the company[merged with Elon Musk’s xAI](https://www.theverge.com/tech/872619/elon-musk-merges-spacex-with-xai-and-x)earlier this year\. According to the filing, the rocket company spent $12\.7 billion in capital expenditures on AI in 2025, or about 61 percent of the total spend\. It spent $7\.7 billion in the first quarter of 2026, compared to just $1 billion on its space division\. SpaceX’s AI division lost $6\.3 billion in operations on $3\.2 billion in revenue in 2025, and lost $2\.5 billion on $818 million in revenue in the first quarter of 2026\.
Meanwhile, Anthropic is cruising toward its first quarterly operating profit, with sales revenue expected reach at least $10\.9 billion, more than double its $4\.8 billion in revenue for the just\-ended March quarter,[Reuters reports](https://www.reuters.com/business/anthropic-nears-first-quarterly-profit-agrees-pay-spacex-125-billion-monthly-2026-05-21/?taid=6a0ea7995bba4e00015c9756&utm_campaign=trueAnthem:+Trending+Content&utm_medium=trueAnthem&utm_source=twitter)\.

Anthropic agreed to pay SpaceX $1.25 billion per month through May 2029 for cloud computing infrastructure, as revealed in SpaceX's IPO filing. The $15 billion annual deal highlights the critical importance of compute resources in AI development.
Anthropic agrees to pay SpaceX nearly $45 billion over three years for compute resources, expanding an earlier partnership that included capacity at SpaceX's Colossus 1 data center.
According to a SpaceX prospectus, Anthropic is paying $1.25 billion per month ($15 billion annually) for compute capacity on SpaceX's Colossus 1 and Colossus 2 supercomputers, far exceeding previously reported estimates and indicating a hefty premium for AI compute.
Anthropic will pay xAI $1.25 billion per month for compute capacity from the Colossus 1 data center, in a deal that could bring xAI over $40 billion in revenue.
Anthropic has surged to a $1.2 trillion valuation and 80x growth, surpassing OpenAI, while securing a major compute deal with SpaceX for the Colossus 1 data center.
