Elon Musk and SpaceX's S-1 Filing Tell Conflicting Stories on Anthropic Compute Deal Duration

Musk’s X Statement Contradicts SEC Filing on Lease Duration

SpaceX CEO Elon Musk publicly downplayed the commitment scope of the xAI-Anthropic compute deal on May 28, 2026, claiming a short-term structure that conflicts with SpaceX’s own regulatory disclosures. According to TechCrunch AI, Musk stated on X that “SpaceX has not committed to leasing Colossus for years,” describing instead a 180-day initial lease with 90-day mutual cancellation rights thereafter. He attributed the brief term to SpaceX’s preference, stating “the short term was our request, not Anthropic’s.”

Yet SpaceX’s S-1 SEC filing, filed in conjunction with the broader xAI financing, presents a materially different picture. Page F-62 of the filing states that “the customer has agreed to pay a monthly fee through May 2029” — a three-year payment obligation beginning in May 2026. The same language appears on pages 13, F-96, and 146, with one iteration specifying “$1.25 billion per month through May 2029,” suggesting this is not a typographical error.

The Material Discrepancy

TechCrunch AI notes that whether Anthropic “agreeing to pay” equates to SpaceX “agreeing to provide” hinges on interpreting the contract itself, which has not been made public. However, the publication raises a structural inconsistency: if either party can exit with 90 days’ notice under Musk’s framing, a one-way multi-year payment lock would be unusual. The SEC filing’s repeated use of the May 2029 endpoint across multiple pages and sections suggests intentional disclosure rather than editorial inconsistency.

Why This Matters

The discrepancy carries immediate implications for xAI’s S-1 valuation and investor confidence in compute availability. A binding three-year $1.25B/month stream represents $45B in committed revenue — a foundation for xAI’s financial projections. If the term is truly 180 days with mutual exit rights, the revenue certainty drops sharply, potentially triggering SEC scrutiny of the S-1’s forward-looking statements. TechCrunch AI observes that such conflicting public and regulatory claims about material terms “is the sort of thing you want to [be accurate about] during a company’s quiet period,” though it notes the SEC’s historical inaction on similar discrepancies from Elon Musk.

xAI declined to clarify the dispute with TechCrunch AI, and neither Anthropic nor SpaceX has issued a public statement reconciling the accounts as of publication. The factual resolution will likely emerge only through SEC review or future litigation, leaving investors and analysts interpreting conflicting signals about the stability of xAI’s largest revenue stream.
