Elon Musk would like everyone to read the fine print.<\/p>\n

On Thursday morning, the billionaire wrote on X that SpaceX has “not committed to leasing Colossus for years” to Anthropic, clarifying that the current AI compute arrangement is a 180-day lease, with 90-day mutual cancellation rights after that.<\/p>\n

That does not contradict one of the most important revelations in SpaceX’s S-1 \u2014 but it does sharpen the caveat around it.<\/p>\n

Inside the sci-fi-ish 277-page financial disclosure document, SpaceX reported a $1.25 billion-a-month deal with Anthropic for access to compute from its Colossus data centers “through May 2029.” The arrangement, if it lasted in full, could rake in more than $40 billion for SpaceX. The S-1 also noted that the “agreements may be terminated by either party upon 90 days’ notice.”<\/p>\n

Musk’s Thursday post added more color about what that means for SpaceX’s side of the bargain: Anthropic may have agreed to pay through May 2029, but SpaceX is saying it has not committed to leasing out the compute for years.<\/p>\n

For SpaceX, the deal was one of the flashiest potential revenue streams in the disclosure. It also mattered because SpaceX’s IPO filing pitched investors on a company becoming much more than rockets and Starlink \u2014 with AI infrastructure as a major part of the story.<\/p>\n

SpaceX has not committed to leasing Colossus for years, although it\u2019s possible that may be what happens.<\/p>\n

This is a 180 day lease with 90 day notice mutual cancellation thereafter. The short term was our request, not Anthropic\u2019s. <\/p>\n

In Thursday’s post, Musk made clear that Anthropic should not get too comfortable on his company’s AI supercomputer. That is especially true if Musk’s own AI-hungry empire \u2014 from xAI to Tesla’s increasingly autonomy-focused business \u2014 needs the processing infrastructure itself.<\/p>\n

“We won’t leave them hanging and will provide a reasonable off-ramp,” he wrote, “but if compute gets super tight I said we might need it back at some point.”<\/p>\n

SpaceX and Anthropic didn’t immediately respond to a request for comment from Business Insider.<\/p>\n
