Anthropic has struck a deal with SpaceX that makes most corporate supply agreements look like a coffee tab. The AI company agreed to spend up to $120.5 billion on compute capacity from SpaceX, tapping into the Colossus data center network in Memphis, Tennessee to feed its growing appetite for AI training and inference.
The agreement, announced on May 6, 2026, grants Anthropic access to more than 220,000 Nvidia GPUs and over 300 megawatts of power, initially through SpaceX’s Colossus 1 facility, with Colossus 2 coming online later.
What the numbers actually look like
Anthropic commits $1.25 billion per month to SpaceX under the terms of the deal, which runs through May 2029. That works out to approximately $15 billion per year, a figure that rivals the annual revenue of entire mid-sized technology companies.
The $120.5 billion headline figure represents the upper bound of total potential spending across all SpaceX-related contracts, according to the source material. Anthropic’s own draft IPO materials put the total projected expenditure at up to $84.5 billion through 2029, suggesting the full ceiling accounts for additional optionality beyond the base contract.
The agreement includes ramp-up discounts in the early stages, which is common for deals at this scale, and both companies retain the right to exit with 90 days notice.
For context, Anthropic’s total infrastructure commitments across all providers now exceed $500 billion, according to the research. SpaceX is one node in a much larger compute network that also includes Amazon and Microsoft.
Why Anthropic needs this much compute
Anthropic’s Claude models have been gaining adoption faster than the company can provision the hardware to serve them. Chronic compute shortages in AI are not unique to Anthropic, but the company has been particularly aggressive in locking up capacity ahead of what it expects to be sustained demand growth.
The Colossus facilities were originally built by xAI, Elon Musk’s AI company, and have since been brought under SpaceX’s infrastructure umbrella. That makes the Anthropic deal notable for reasons beyond raw compute: Musk has been publicly critical of Anthropic in the past, and his xAI develops Grok, a direct competitor to Claude.
SpaceX, for its part, appears to be using its excess AI infrastructure capacity as a revenue-generating asset ahead of its own expected IPO.
The orbital data center question
Both Anthropic and SpaceX have reportedly expressed interest in pursuing gigawatt-scale, space-based AI compute solutions in the future. No formal agreements exist around orbital infrastructure at this stage. The current deal is strictly terrestrial.
Anthropic’s $1.25 billion monthly commitment also carries a signal about the company’s confidence in its own revenue trajectory. Whether that confidence is warranted will become clearer once Anthropic’s IPO materials are finalized and its financials are public.
