Anthropic is paying $15 billion a year for access to Elon Musk’s data centers
Earlier this month, SpaceX and Anthropic announced a new IT partnership that provides access to the rocket company’s Colossus data centers in Memphis, Tennessee. Now, with the release of SpaceX’s IPO filing, we have more details about this deal, including how much Anthropic is paying Elon Musk’s company.
In its S-1 filing, SpaceX said 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 a year, nearly double the $18.7 billion in revenue SpaceX reported for all of 2025.
The agreement includes a clause in which either company can terminate the agreement within 90 days. And Anthropic’s fees will be reduced as capacity ramps up this month and next.

In an article on SpaceX “offers AI computing as a service at scale,” he said.
SpaceX has spent huge amounts of money on AI since the company merged with Elon Musk’s xAI earlier this year. According to the filing, the rocket company spent $12.7 billion on AI capital expenditures in 2025, or about 61% of total spending. It spent $7.7 billion in the first quarter of 2026, compared to just $1 billion for 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 closing in on its first quarterly operating profit, with expected revenue of at least $10.9 billion, more than double the $4.8 billion in revenue from the just-ended March quarter, Reuters reports.
