SpaceX's $29B Google AI Deal Can Be Ended on 90 Days' Notice

Alphabet's capacity crunch is the immediate backdrop: the company is spending around $200 billion in capex this year, with more expected next year, yet its Google Cloud backlog grew to $514 billion last quarter from $460 billion the prior quarter. On its second-quarter earnings call, CFO Anat Ashkenazi described leasing third-party data centers as a "bridging strategy while we build out more internal capacity." SpaceX is one of the neoclouds filling that gap, but the arrangement looks temporary by design, which may be why SpaceX's contract terms are structured the way they are.

The deeper risk is that SpaceX's AI revenue depends on scarcity rather than any proven edge. If the industry build-out brings supply and demand into balance, Alphabet and Anthropic — SpaceX's biggest infrastructure customers — could meet their needs internally, and SpaceX might not be able to command Musk's estimated $30–$50 per watt pricing, stretching the payback period on its data-center capital. SpaceX's stated counter would be cost advantages, potentially via orbital data centers, but that would require deploying multiple technologies at scale that it has not yet perfected. Alphabet's stake in SpaceX and the lockup running until the third quarter of 2027 add one more layer: it seems unlikely Alphabet walks away early, though that restraint may be financial rather than operational.
