SpaceX shares slide as debut earnings reveal AI spending surge

SpaceX's first quarterly report as a public company did the thing a bull would want on the top line, and the market still sold it off. That gap is the interesting part.

Revenue nearly doubled year over year to $7.8bn, ahead of analyst expectations of about $6.9bn, BBC News reported. What tanked the stock was the spending line underneath. Capital expenditure ballooned to about $18.4bn in the quarter, more than six times the year-ago figure, with almost $16bn of it going into AI compute infrastructure. The dedicated AI compute revenue line pulled in $2.56bn, up 247% year over year, on contracts with Anthropic, Google, and Reflection AI, according to CNBC. Shares fell between 6% and 8% in after-hours trading immediately after the release and continued sliding, down 12% by Wednesday.

The signal to take from this is not that AI capex is bad. It is that a revenue beat, on its own, is no longer enough to underwrite it. Every AI-heavy public company is now being graded on payback speed, and SpaceX's CFO reportedly told investors the company is getting less than a one-year payback on AI compute capital deployed, an aggressive claim for infrastructure at this scale. Wendy Souvannarath, the chief executive of Carré Partners, which has invested in SpaceX, defended the strategy on the BBC's Today programme, saying "every tech giant is spending like this right now" and that the company is treating the AI build-out as a running cost that pays for itself within a year.

Some of the drama around the call came from Musk himself, who pulled his $1 trillion annual revenue target forward from 2031 to 2030 and described plans for moon-based robot manufacturing in terms he admitted sounded "totally nuts", per Fortune. Investors seemed more focused on the near-term compute contracts than the lunar vision.

The honest caveat is what the reporting does not give you: the gross margin on that $2.56bn AI compute line, how much of it is standalone versus bundled with Starlink, and the exact size and timing of the coming insider share unlock. Those will decide whether this sell-off was a routine repricing or an early warning. If SpaceX can validate its payback claim over the next couple of quarters, it becomes the public comparable every other AI infrastructure story is measured against, and a second scaled compute buyer outside the hyperscaler triumvirate that labs like Anthropic will quietly welcome.
