TeraFab

Short answer: TeraFab is the AI-chip complex that SpaceX and Tesla plan to build in Grimes County, Texas. It would make, package and test logic and memory chips under one roof.

Texas announced the first phase on Aug 6, 2026: more than $16.8 billion, 3,000 jobs and a 100-million-square-foot facility. Tax filings sketch four phases worth up to about $119 billion, but the later phases aren't committed.

The write-up

Musk's planned chip plant would cover 100 million square feet. TeraFab, Grimes County, Texas. Phase 1: $16.8 billion.

  1. Exhibit A

    A chip plant in Grimes County

    On Aug 6, 2026, Texas Governor Greg Abbott announced that SpaceX will build Terafab, a vertically integrated semiconductor fabrication plant, in Grimes County, about 20 miles east of College Station, near Gibbons Creek Reservoir.

  2. Exhibit B

    Everything under one roof

    Terafab is meant to make, package and test advanced logic and memory chips in one place. In Musk's words, it combines 'logic, memory, and advanced packaging all under one roof'.

  3. Exhibit C

    $16.8 billion to start

    The first phase is a capital investment of more than $16.8 billion with 3,000 new jobs. The total is about $10.37 billion in the Anderson-Shiro district plus $6.43 billion in the Iola district. Texas added a $30 million Texas Enterprise Fund grant.

  4. Exhibit D

    100 million square feet

    The planned facility covers 100 million square feet. The chips are meant for Tesla's Optimus robots and Cybercabs and for SpaceX's space-based data centers.

  5. Exhibit E

    Up to $119 billion, if every phase gets built

    State tax-incentive filings describe four phases (2026–28, 2029–31, 2032–34, 2035–36) totalling about $119.4 billion. The applicant says it will decide on each later phase only after finishing the one before.

  6. Exhibit F

    Who's behind it

    The filings were made by TeraFab AI, LLC, a SpaceX-linked entity. ENR describes the project as led by affiliated companies including SpaceX, Tesla and xAI.

  7. Exhibit G

    Timeline

    First-phase construction is projected for 2026–28, with commercial operations expected to begin in 2028.
