TERAFAB
The fab to end all fabs.
The dedicated AI semiconductor manufacturing complex announced by Tesla, SpaceX, and xAI. Engineered for vertically integrated compute at gigawatt scale.
THE ORIGIN
From an existential supply bottleneck to ground breaking in the Texas prairie. Four pivotal milestones that forced the creation of a private semiconductor empire:
THE SITE
GRIMES COUNTY, TEXAS · 30.55°N, 95.98°W
Outside Houston, 100M+ sq ft of planned manufacturing space — "the largest and most valuable building on Earth by far."
Directly coupled to dedicated multi-gigawatt solar arrays, independent water reclamation, and hardened ultra-high-voltage power routing.
THE SCALE
Scaled by square root of floor area for visibility against Earth's largest human architectural footprints:
THE FLOW
Vertical integration under one continuous cleanroom roof. Wafers traverse four hermetic automated gates from raw silicon crystal to tested multi-die stacks:
THE SPLIT
Two fabs, two specialized chips. One descends toward the planetary edge fleet; one ascends into orbital constellations:
Goal: one terawatt of compute per year; today's global output covers ~3% of what Musk's companies expect to need.
