The Anthropic-deal contradiction is a securities-law fault line, not a tweet fight
The most consequential disclosure in SpaceX's S-1 may be the one Elon Musk publicly disputed. The prospectus describes Anthropic as a multi-year compute customer at xAI's 300 MW Colossus 1 data center near Memphis, paying roughly $1.25 billion per month, with the contract running through May 2029 — implying more than $40 billion in committed revenue tied to a single counterparty [1]. That single line item is what lets the AI segment carry a trillion-dollar slice of the valuation despite generating only $818M of Q1 2026 revenue against $2.47B of losses [2].
Then Musk posted that the arrangement is actually 'a 180 day lease with 90 day notice mutual cancellation thereafter' [3]. The economic difference is enormous: a five-year contract is a backlog you can borrow against; a six-month lease with a 90-day kill switch is closer to a month-to-month commitment. Columbia Law's Eric Talley framed the problem as binary — either the S-1 is materially misleading or Musk's post is [4]. Securities-law professor Ann Lipton was slightly gentler, saying the two stories may be 'reconcilable,' but still notes the post 'does appear to contradict the filing' [5]. For underwriters trying to price SPCX on June 11, the question is no longer just 'how big is the AI revenue stream' but 'which version of it do we put in the marketing deck.'
