Anthropic is committing $1.25 billion per month to SpaceX through May 2029 in a sprawling computational partnership that underscores the artificial intelligence industry's insatiable appetite for processing power and raises the stakes for both companies.
The monthly figure, disclosed in SpaceX's initial public offering filing Wednesday, translates to roughly $15 billion annually. The arrangement represents a substantial outlay for Anthropic, which has struggled to secure adequate compute resources to train and run its AI systems. For SpaceX, it amounts to a significant revenue injection at a moment when the company is courting public investors and seeking to diversify beyond rockets and satellites.
SpaceX disclosed in its IPO filing that the monthly payments will taper in May and June as the deal ramps up operations. The disclosure came as Anthropic announced it was expanding beyond SpaceX's Colossus 1 facility to tap into Colossus 2, where it plans to scale up its use of Nvidia GB200 processors throughout June.
For context, SpaceX generates roughly $18 billion in annual revenue across its entire business, making this single compute contract a material addition to the company's top line. Anthropic, meanwhile, has been racing to monetize its Claude AI model and expand its customer base, but the company remains constrained by compute availability, a challenge that has driven it to pursue external arrangements like this one.
Tom Brown, Anthropic's co-founder and chief compute officer, announced the expansion on social media, framing it as a scaling initiative rather than a scramble for resources. Both companies presented the arrangement as part of their long-term vision for AI infrastructure.
The partnership is not locked in stone. Either party can exit with 90 days' notice, according to SpaceX's filing, giving both companies a modest escape hatch if the arrangement proves unsatisfactory or if circumstances change.
SpaceX signaled broader ambitions in the compute-leasing space, stating in the IPO filing that it expects to pursue additional similar contracts while maintaining sufficient capacity for its own AI model development and training needs.
Author James Rodriguez: "This is a staggering sum that shows just how desperate the AI arms race has become, and how much muscle SpaceX brings to the table beyond launch services."
