On 14 August 2026 CNBC reported Nvidia's stake in SpaceX — which came through an investment in xAI — was worth about $21 billion at the end of the second quarter. Ars Technica carried the same disclosure into the tech press. The Financial Times later noted SpaceX shares had fallen after the June IPO, which would mark the stake closer to $17 billion on that later print.
The through-line is circular capital: Nvidia sells GPUs into xAI and other Musk-orbit trainers; some of that cash shows up as a rocket-company holding. AI chips, launch, and satellite bandwidth are now one balance-sheet story.
A $21 billion line item is large even for Nvidia. It also concentrates governance risk. If SpaceX or xAI stumbles, the world's most valuable chipmaker is more exposed to one founder's stack than a GPU vendor used to be.
Readers should treat the dollar figure as mark-to-market, not cash. Illiquid or newly public slices move. The strategic fact is the coupling, not the last print.
