Anthropic could spend as much as $84.5 billion through 2029 on Nvidia-based computing capacity supplied by xAI, the artificial intelligence company owned by Elon Musk's SpaceX, according to a confidential IPO prospectus reported by Reuters on Sept. 29.
The agreements can mostly be canceled with 90 days' notice and are part of Anthropic's much larger AI infrastructure buildout.
The Claude developer expects to spend at least $518 billion over the next decade across six infrastructure partners as access to computing power becomes increasingly important to training advanced AI models.

Anthropic said future growth could be “limited principally by the availability of compute.”
The latest disclosure expands on a partnership announced in May. SpaceX said Anthropic had agreed to pay $1.25 billion per month through May 2029 for access to roughly 325,000 Nvidia GPUs across its Colossus computing infrastructure, a commitment worth nearly $45 billion over the full term.
SpaceX has been moving deeper into AI since acquiring xAI in February. The combination brought Musk’s Grok developer under SpaceX while allowing the company to use its growing computing infrastructure internally and lease capacity to outside customers including Anthropic and Google.
The disclosure lands as Wall Street analysts increasingly view AI infrastructure as a major part of SpaceX’s future.
TD Cowen initiated coverage of SpaceX on Sept. 29 with a Buy rating and $200 price target. Analyst John Blackledge said terrestrial AI compute leasing could become the company’s fastest-growing business. He expects it to make up most of the company's revenue by early 2027.
“The biggest near-term driver of SPCX revenue is leasing terrestrial AI compute capacity to frontier labs and other companies,” Blackledge said, He pointed to the current mismatch between AI computing supply and the demand for it.
TD Cowen expects SpaceX’s computing capacity to rise from 2.1 gigawatts in 2026 to 6 gigawatts by the end of 2027. The firm also estimates that AI compute leasing could represent about 60% of company revenue next year.
At press time, SpaceX shares were trading at $148.18, up about 1.9% on the day, according to TradingView data.
