Tesla or SpaceX: Who Benefits More From Terafab and How

SpaceX’s 247% AI segment growth and $93.5 billion cash pile give it more leverage than Tesla in allocating Terafab output.

  • Tesla and SpaceX confirmed Terafab last week, a $16.8 billion semiconductor plant in Grimes County, Texas, designed as the largest chip manufacturing facility on the planet.
  • SpaceX's 247% AI segment growth and $93.5B cash pile provide significantly more Terafab upside than Tesla, whose free cash flow turned negative at $1.09 billion and operating margin collapsed to 1.4%.
  • Despite Tesla co-owning the facility, the project will utilize natural gas plants and large battery arrays rather than Tesla solar, which markets solar-plus-storage as an AI power solution.
  • SpaceX holds $14.1B in signed cloud agreements and a pending $60B Cursor deal, making wafer allocation at Terafab the critical signal for its future compute capacity demands.
  • Tesla needs Terafab to protect gross margins on millions of vehicles and eventually one million Optimus units annually, while SpaceX leverages the fab for Starlink and Starship avionics.
