Overview
- Elon Musk wrote on X that the Colossus compute arrangement with Anthropic is a 180‑day lease with mutual 90‑day exit rights after the initial term, a clarification he posted on Thursday.
- SpaceX’s S‑1 prospectus, however, states Anthropic agreed to pay $1.25 billion per month through May 2029, language that frames the deal as a multi‑year revenue commitment.
- The two descriptions are inconsistent and neither company has publicly reconciled them, leaving unanswered legal, accounting and disclosure questions for potential investors and the SEC.
- Operationally the structure Musk described gives SpaceX the option to reclaim capacity if internal demand rises while Anthropic gains immediate access to Colossus’s reported >220,000 Nvidia GPUs and about 300 megawatts of power for inference workloads.
- The dispute matters for SpaceX’s IPO story because the Colossus deal is cited as a major new revenue source and it highlights a wider industry trend of firms leasing large GPU clusters while exploring longer‑term ideas such as orbital data centers.
