Musk says SpaceX and Tesla to build advanced chip factories in Austin

Elon Musk's $25 billion Terafab in Austin aims to produce up to 1 terawatt of AI compute annually, addressing chip shortages for Tesla, SpaceX, and xAI projects.

  • At a Seaholm event, Musk unveiled the Terafab, describing it as a comprehensive chip facility with integrated R&D, testing, and packaging, saying 'To the best of my knowledge, this doesn’t exist anywhere in the world'.
  • Last week Musk teased the Terafab project, saying it will integrate Tesla, SpaceX and xAI to accelerate autonomy and AGI, with space-based solar-powered AI satellites lowering compute costs.
  • The facility’s closed-loop design includes on-site photomask manufacturing, wafer fabrication, testing, and packaging, aiming for initial operational capability late 2026.
  • One immediate outcome is a chip for Tesla vehicles and Optimus, with production volumes expected to exceed car output and a space-optimized D3 chip for satellites ramping in 2027.
  • Positioned at scale, the project aims to produce ~1 terawatt yearly, with roughly 80% for space and 20% for ground, while Musk proposed an industrial base on the moon and free trips to Saturn.
