Tesla's Terafab semiconductor manufacturing site in Grimes County, Texas is shaping up to be one of the largest industrial footprints in the state. Aerial tracker Joe Tegtmeyer reported overnight that the project currently sits at roughly 6,640 acres (2,690 hectares) of owned land — with an additional 2,300 acres (930 hectares) still working through final acquisition stages.
Once those pending parcels close, the total site would reach nearly 9,000 acres — a footprint comparable to a small city. Terafab is purpose-built for advanced chip production, distinct from Tesla's vehicle assembly operations, and is widely understood to support the company's push toward in-house semiconductor supply for vehicles, AI hardware, and robotics. At this scale, the land alone suggests Tesla is planning for decades of capacity growth, not just a single fab building.
Tegtmeyer's note that the site is "only going to grow much larger" implies additional land deals beyond the current 2,300-acre pending tranche are likely already in motion. How that capacity ultimately gets allocated — between automotive chips, Dojo AI training hardware, or Optimus robotics — remains the open question worth watching.
