Elon Musk has never been accused of thinking small. But Terafab, his newly unveiled semiconductor fabrication initiative, makes a Gigafactory look like a lemonade stand.

Announced on March 21, 2026, the project brings together Tesla, SpaceX, xAI, and now Intel under one sprawling roof in Texas, with the stated goal of producing roughly 50 times the current global semiconductor fab output. The price tag? An initial estimate of $20B to $25B that has since ballooned to $55B for phase one alone, with total costs potentially reaching $119B.

What Terafab actually is

This isn’t just another chip factory. Terafab is designed to consolidate logic chips, high bandwidth memory, and advanced packaging into a single location. Instead of shipping half-finished silicon across three continents before it becomes a usable chip, everything happens under one roof.

The facility design references up to 100 million square feet of space, which is roughly the size of 1,700 football fields. Permitting applications have been filed in Grimes County, Texas, though the project remains in its preliminary phases.
