The financial specifics were outlined in SpaceX’s newly released IPO filing, which contains a provision allowing either party to terminate the agreement within 90 days. Earlier this month, SpaceX and Anthropic announced a new compute partnership granting access to SpaceX’s Colossus data centers in Memphis, TN. The details, including Anthropic’s payment to Elon Musk’s company, have been disclosed with SpaceX’s IPO filing. According to the S-1 filing, Anthropic agreed to pay $1.25 billion monthly through May 2029 for access to SpaceX’s AI training centers at Colossus I and II, totaling $15 billion annually, nearly double SpaceX’s $18.7 billion revenue in 2025. The agreement includes a 90-day termination clause. Anthropic’s fees will be reduced during the capacity ramp-up this month and next. This exit clause likely reflects the fast-paced nature of the AI industry. In some aspects, Anthropic’s Claude competes with X’s Grok, illustrating how AI companies like Anthropic urgently need compute capacity amidst local opposition to data center expansions. Musk stated on X that SpaceX is ready to offer similar data center access deals to other AI companies, emphasizing AI compute as a service at scale. Since merging with Musk’s xAI earlier this year, SpaceX has heavily invested in AI, spending $12.7 billion on capital expenditures in 2025, comprising 61% of total spending, and $7.7 billion in the first quarter of 2026, compared to $1 billion on its space division. SpaceX’s AI division faced losses of $6.3 billion on $3.2 billion revenue in 2025, and $2.5 billion on $818 million revenue in early 2026. Meanwhile, Anthropic is approaching its first quarterly operating profit, with projected sales revenue of at least $10.9 billion, more than double its $4.8 billion revenue in the March quarter, Reuters reports.
