SpaceX and Tesla to spend $16.8 billion on Terafab chip plant in Texas
SpaceX · Tesla
The joint venture's Grimes County, Texas complex will make AI chips for Tesla robots and SpaceX's planned space-based data centers.
what happened
SpaceX and Tesla said they will initially invest $16.8 billion to build Terafab, a vertically integrated, roughly 100-million-square-foot semiconductor complex in Grimes County, Texas, per TechCrunch and Reuters. The plant will make, package, and test advanced logic and memory chips designed for edge computing and inference, intended to supply processors for Tesla's Optimus robots and Cybercabs and high-power chips for SpaceX's planned space-based data centers. SpaceX has previously filed for a potential total investment of up to $119 billion across multiple construction phases. Elon Musk said the facility is meant to close the gap between global chip supply and the more than 1 terawatt of computing power he says SpaceX and Tesla will need; the facility is expected to employ at least 3,000 people, and Intel is a manufacturing partner.
why it matters
This is SpaceX's largest disclosed capital commitment since its June IPO and confirms the company is directing fresh public-market capital toward chip manufacturing rather than launch or Starlink capacity, a bet that its in-house compute ambitions, including the orbital data centers it has floated, depend on supply it cannot source externally at the scale it wants.
