Tesla and SpaceX Invest $16.8 Billion in Terafab Semiconductor Complex
Tesla and SpaceX are committing $16.8 billion to build Terafab, a semiconductor facility in Texas, targeting 1 terawatt of computing demand. The project raises questions about funding sources, output allocation, and the complexity of semiconductor manufacturing.

Tesla and SpaceX are investing $16.8 billion in Terafab, a semiconductor complex in Grimes County, Texas, aimed at producing advanced chips. Analysts project that the total cost for the fully expanded project could reach $119 billion, highlighting the scale of the investment.
Approximately 25% of the output may serve Tesla's Optimus robots, while 75% could support SpaceX's AI spacecraft. Concerns persist regarding funding, as Tesla has already planned over $20 billion in capital expenditure for 2026, excluding Terafab.
The complexity of high-volume semiconductor manufacturing raises risks, as analysts emphasize the need for clarity on contracts and responsibilities. Delivering on production targets by 2029 remains uncertain, with essential milestones still pending.
