Cut to three months later, in May, when SpaceX’s IPO filing revealed an agreement with Anthropic to pay the former “$1.25 billion per month through May 2029” for a boost in compute capacity via 325,000 Nvidia GPUs through SpaceX’s Colossus servers — a deal believed to be worth around $45 billion at the time.
As it turns out, the SpaceX-Anthropic deal is actually worth almost twice as much. As Reuters reported, a peek into Anthropic’s IPO prospectus revealed it could end up spending up to $84.5 billion through 2029 on compute capacity from SpaceXAI, formerly known as xAI, an artificial intelligence company founded by Musk that became a subsidiary of SpaceX [NASDAQ: SPCX] in February 2026.
Perhaps the win-win nature of the Musk-Anthropic deal simply overrode any underlying animosity. Axios, for example, speculated that, for Musk, it helped significantly boost SpaceX’s revenue ahead of its IPO filing, while at the same time giving Anthropic the compute boost it so desperately needed. Neither SpaceX nor Anthropic replied to Moneywise’s request for comment.
Meanwhile, the contract with SpaceX is only one small part of a massive, $518 billion spending spree that Anthropic is reportedly undertaking over the next decade to keep pace in the AI race.
Anthropic’s $518 billion AI wager
Reuters reported that Anthropic’s IPO prospectus shows the company “is making a massive bet that AI will transform the global economy more profoundly than industrialization, electricity and the internet.”
That’s a heck of a wager — one that Anthropic is apparently willing to put $518 billion down on.
For perspective, Goldman Sachs, in August, predicted “$1 trillion of AI-related investment around the globe in 2026, including $581 billion in the U.S.” — with Anthropic now accounting for more than half of that global total and virtually all of the national total on its own.
According to Reuters, Anthropic’s spending is meant to increase its AI infrastructure and computing power, the latter of which being described as “the key constraint on AI development, as future demand for advanced AI systems is likely to exceed available supply.” It includes deals with Google ($111.1 billion), Amazon ($110 billion) and Microsoft ($31.4 billion), as well as paying Broadcom $161.2 billion for equipment leases.
The Reuters report also noted that, while the SpaceX deal has an out, 80% of the spending Anthropic committed to is “non-cancelable or requires payment regardless of usage.”
