Rural Texas is now at the center of what could become the most consequential semiconductor investment in U.S. history. A public notice filed by Grimes County names Space Exploration Technologies Corp. SpaceX as the business prospect behind a proposed multi-phase, vertically integrated semiconductor manufacturing and advanced computing fabrication facility near Gibbons Creek Reservoir, approximately 20 miles east of Bryan-College Station. Scale here isn’t just notable — it’s unprecedented.
The county’s notice estimates $55 billion in capital investment for initial phases, with the total reaching as high as $119 billion if additional phases are built. That figure alone would dwarf nearly every prior domestic manufacturing commitment on record.
TeraFab, announced by Elon Musk in March 2026, isn’t a conventional chip contract arrangement. Facility is designed to vertically integrate the entire chip production pipeline — design, lithography, fabrication, memory, advanced packaging, and testing — all under one roof. The Grimes County site, designated under the SpaceX Reinvestment Zone No. 1 – 2026-001, would represent the permanent, large-scale campus for that ambition.
The permanent TeraFab campus is expected to require thousands of acres at a yet-to-be-determined location, with the current Gigafactory Texas site serving as the initial prototype fabrication hub before the larger buildout begins. Grimes County fits that “thousands of acres” mandate — Gibbons Creek Reservoir and its surrounding land offer the kind of footprint that Austin simply can’t.
Elon responded to the news by stating this is one of several locations under consideration for what he describes as “the largest and most advanced chip fabrication facility in the world.” Characteristically direct.
Not everyone in Grimes County is celebrating. Residents say they have more questions than answers, frustrated by the lack of communication from county leadership — and a community group formed months ago in response to proposed data center developments is already pushing back on the process.
A formal public hearing for the SpaceX / TeraFab development is set for June 3, 2026, at 9 a.m. at the Grimes County Justice & Business Center in Anderson. That session could determine whether this transformative capital commitment moves forward — or stalls on local resistance.
At $119 billion, this isn’t just a SpaceX / TeraFab play. It’s a full-on fabrication of the future.
