Nvidia would be the biggest winner of SpaceX's proposed compute spending because its GPUs are too good for SpaceX to replicate in-house. If SpaceX builds all 13 GW by end-2027, about $470B of capex over five quarters could yield $414B of Nvidia revenue from one customer, with an estimated $310B in gross profit and $200B in net income. Nvidia's share of each dollar rises from about 83% with Blackwell to 89% with Vera Rubin, expected to ship at scale from Q2 2027. x.comÂ
