SpaceX is selling compute to Anthropic at $1.25B a month: what actually changed
On July 4, a widely-circulated post by @AYi_AInotes highlighted a line buried in SpaceX’s revised IPO filings: SpaceX is supplying Anthropic with $1.25 billion of compute every month, under a contract running through May 2029, with either side able to terminate on 90 days notice.

Read these three together and the story is not “Anthropic bought more compute.” It is that AI compute has quietly moved from being a cloud resource you rent by the token, to a piece of industrial infrastructure you buy on multi-year fixed contracts. In industrial-age language this is called a power purchase agreement (PPA). In the AI era it is still the same shape: a customer locks in capacity at a fixed price, the supplier locks in cash flow to build.
