A reported mid-2027 compute arrangement between Anthropic and SpaceX has drawn fresh attention because of a 90-day exit clause, the size of the contract ceiling, and comments from investors and Elon Musk about what happens if data-center supply tightens, Tesla North reported.

Tesla North, citing analysis circulated by semiconductor analyst Jukan of Citrini Research, said the $120.5 billion figure attached to the deal is a ceiling rather than guaranteed revenue. The initial non-cancelable periods end in January 2027 and March 2027. After that, either side can terminate with 90 days' written notice, the report said. An unnamed client labeled Customer B accounted for 34.5% of SpaceX's third-quarter revenue, all of it in the Super Intelligence segment, and that customer has reportedly been identified as Anthropic.

Those terms matter because they cut both ways. On the Nov. 7 episode of All-In, Chamath Palihapitiya said that if data-center supply tightened, SpaceX could end the Anthropic deal on 90 days' notice and reprice the compute at the spot rate. "So whatever revenue you see on SpaceX's balance sheet from Anth could 2 to 3X," he said, "and Anth would have no choice except to immediately capitulate and take the higher price." In a follow-up post on Sunday, Palihapitiya wrote that "odds will go up with every data center delay" if tight supply lifted spot prices by 50% or more and a seller of powered compute had a 90-day exit, Tesla North reported. The filing, as the site described it, allows that cancellation only after the early-2027 periods end. Musk has separately warned that SpaceX revenue could fall if compute becomes plentiful and cheap.

The same analyst notes first said developing Opus 5.5 cost more than $10 billion. Jukan later posted a correction, saying the $10 billion was reportedly spent training the entire Claude 5.5 model family, including Opus 5.5, and that the family includes Sonnet 5.5 and Haiku 5.5. Anthropic has not disclosed a training cost in its public materials on the 5.5 models, Tesla North reported. Those are reported figures and a correction, not an official Anthropic total.

Tesla North also noted comments that followed Democrats winning control of both the House and the Senate in the Nov. 3 midterms, as Reuters reported. Data centers were already in the spotlight. Voters in 10 states backed restrictions or rejected local data-center proposals, Reuters later reported. After the election, Sen. Bernie Sanders, who caucuses with Democrats, wrote "National data center moratorium now," and Texas Gov.-elect Gina Hinojosa had said she would pause new data-center approvals until the legislature could pass protective laws, CNBC reported, according to Tesla North.

This is a SpaceX and Anthropic compute story, not a change to Tesla vehicle software, FSD subscriptions or owner hardware. The facts to hold onto are the ones in the report: a $120.5 billion ceiling, non-cancelable periods into early 2027, a 90-day exit after that, and no public confirmation from Anthropic of the $10 billion training-cost figure. Tesla North did not report that the contract has already been canceled or repriced.
