    SpaceX and Tesla partner to build $55B to $119B Terafab semiconductor plant

    Question

    SpaceX and Tesla partner to build $55B to $119B Terafab semiconductor plant

    Direct answer

    Tesla and SpaceX have outlined plans to build Terafab, a 100 million-square-foot semiconductor fabrication facility projected to cost between $55 billion and $119 billion. Initial site construction is scheduled to commence in December 2026, targeting initial chip manufacturing by 2028. The project underscores an aggressive push for vertically integrated compute infrastructure. However, the capital commitment adds substantial future cash demands onto Tesla, which has already seen operating margins contract to 1.4% alongside more than $25 billion in AI and robotaxi expenditures.
