Cheaper AI Compute Could Cut SpaceX Revenue

Elon Musk says SpaceX’s AI compute revenue could fall if computing capacity becomes plentiful and cheap, highlighting a pricing risk behind the company’s ambitious growth forecasts.

“If compute becomes plentiful and cheap, SpaceX revenue will drop,” Musk wrote in a reply on X. He added: “No crying in the casino for either party.”

Musk was responding to a discussion about whether tight data-center supply could give SpaceX more pricing power in its compute relationship with Anthropic. His reply raised the opposite scenario: more available capacity at lower prices could reduce what SpaceX earns from selling compute.

The scale of that business is substantial. Anthropic’s IPO filing disclosed agreements to spend up to $120.5 billion on SpaceX compute through 2029. Payments would reach roughly $3.1 billion a month once all contracted capacity is delivered, which Anthropic expected in December 2026.

Those agreements also give both companies flexibility. Their initial non-cancelable periods end in January and March 2027, after which either side can terminate with 90 days’ written notice. The $120.5 billion figure is therefore a potential total, rather than guaranteed revenue.

SpaceX’s actual third-quarter results put the growth in perspective: total revenue reached $14.6 billion, including $7.6 billion from Super Intelligence. That segment includes cloud services, software and advertising, so its revenue is broader than compute rentals alone. SpaceX also spent $16.4 billion on SI capital expenditures during the quarter.

On the earnings call, Musk outlined a much larger $500 billion to $1 trillion annual recurring revenue target for the end of 2027. An annualized run rate describes the pace of revenue at a particular point, not the amount already earned over a full year.

CFO Bret Johnsen separately forecast $33 billion to $37 billion in total company revenue for the first quarter of 2027.

His latest post did not revise that target, announce an Anthropic price change or disclose falling revenue. It was a conditional warning that building more capacity does not, by itself, guarantee the same prices.

Do you think AI demand will keep outpacing supply, or will cheaper compute change SpaceX’s economics?
