The Space Force awarded SpaceX a $2.29 billion fixed-price agreement to build a satellite communications backbone meant to link the sensors and interceptors of the Golden Dome missile-defense effort. It is an other transaction agreement, not reported on USAspending, so how much has been paid is not public.

Awarded to SpaceX by U.S. Space Force

Tie Musk founded SpaceX and is its CEO and chairman. Its June 2026 IPO prospectus says he will hold about 82.4% of the voting power after the offering.
