SpaceX GPU rentals could yield $26B annually, key to $1.8T valuation

SpaceX has discovered a surprisingly lucrative revenue stream by capitalizing on a structural imbalance in the AI infrastructure market: demand for computing power continues to outpace supply, and building large data centers requires years of development and massive capital investment. By renting unused GPU capacity from infrastructure already built to support xAI's Grok model, SpaceX can charge premium rates to customers who need computing power immediately. The timing is critical—with OpenAI and partners pursuing the Stargate initiative to build a nationwide data center network, the current shortage of AI infrastructure may not persist indefinitely, making SpaceX's existing capacity particularly valuable in the near term.

The $26 billion（約4.2兆円） in annual revenue from Anthropic and Google contracts alone exceeds SpaceX's entire 2024 revenue of $18.7 billion（約3兆円）, yet the business model carries structural uncertainty. Both contracts include 90-day cancellation provisions that cut both ways: SpaceX can reclaim capacity if internal demand for Grok training intensifies, but customers retain exit rights if cheaper alternatives emerge. Analyst Sean Cray of Moody's notes this creates a question mark around whether compute rental will become a permanent revenue stream or remain temporary—a distinction critical to whether it truly justifies SpaceX's $1.8 trillion（約290兆円） valuation. A potential Pentagon contract reported by the Wall Street Journal, if finalized, could provide evidence that government and enterprise demand for isolated compute infrastructure is durable, not ephemeral.
