Elon Musk's massive Terafab chip-making facility starts to take shape — 100 million square feet of manufacturing space and $16.8B initial capital investment

SpaceX and Tesla unveiled plans for the initial phase of their Terafab project, an ambitious semiconductor manufacturing complex set to span over 100 million square feet in Grimes County, Texas. The project is projected to require a $16.8 billion initial investment, a significant capital commitment given the current global semiconductor supply constraints.

The Terafab facility, envisioned to be a vertically integrated manufacturing campus, will specialize in AI inference processors for Tesla's Optimus humanoid robots and Cybercab autonomous vehicles, as well as high-power processors for SpaceX's space-based data centers. This move comes as SpaceX, Tesla, and xAI already consume more than one terawatt (TW) of compute per year, significantly surpassing today's global supply.

The project aims to consolidate advanced logic devices, memory chips, packaging, and testing operations under one roof, potentially shortening production cycles and enhancing time-to-yield. SpaceX and Tesla have not disclosed a timeline for when their combined demand for compute will hit the 1 TW benchmark. The Terafab site, belonging to SpaceX, will occupy four massive buildings and is expected to employ at least 3,000 people, with a significant portion likely to be residents of Grimes and nearby Brazos County.
