SpaceX wants to grow its compute capacity more than fivefold by the end of 2027, finishing the year above two gigawatts of power, according to Elon Musk. The entire buildout will run on Nvidia chips.

Musk shared the target during SpaceX's Q2 earnings call. By the end of 2027, capacity should be closer to ten gigawatts than five, he said. The company currently sits at 1.4 gigawatts, according to its quarterly report. SpaceX plans to build on Nvidia's upcoming Vera Rubin platform, which Musk called the best architecture available. The existing Colossus clusters run on Nvidia's H100, GB200, and GB300 systems.
