Commonwealth Fusion Systems installs reactor magnet, lands deal with Nvidia

This is the first fusion news that doesn't feel like marketing theater. CFS is past the "we promise it'll work" phase and actually building. The Sparc reactor's on track, Nvidia's buying in, and they're building digital twins to optimize—that's engineer talk, not startup bluster.

Here's the thing: fusion power's been "30 years away" for 60 years. But CFS shipped superconducting magnets that actually work at scale. The Nvidia deal matters less for cash and more because it signals someone credible thinks this isn't vapor.

Real talk: even if they nail it, we're looking at 2030+ for commercial capacity. Still better than "never."
