    SpaceX and Tesla plan 100M sq ft Terafab semiconductor facility costing $55B-$119B

    Question

    SpaceX and Tesla plan 100M sq ft Terafab semiconductor facility costing $55B-$119B

    Direct answer

    SpaceX and Tesla have outlined plans to construct Terafab, a joint 100 million-square-foot semiconductor manufacturing plant with capital costs estimated between $55 billion and $119 billion. Groundbreaking is set for December 2026, with the initial phase anticipated to come online in 2028 to supply custom silicon for autonomous driving and AI compute initiatives. The scale of the investment represents a significant vertical integration effort, introducing long-dated capital allocation and execution commitments for Tesla.
