SpaceX filed a property-tax abatement application on May 6, 2026, proposing Terafab, a multi-phase semiconductor and advanced-computing fabrication campus near Gibbons Creek Reservoir in Grimes County, Texas. A public hearing is scheduled for June 3, 2026.
Local Filing and Approvals
SpaceX submitted the property-tax abatement application to Grimes County, where it was posted on the county government website. The filing requests tax relief for land around Gibbons Creek Reservoir and adjacent parcels. The Grimes County Commissioners Court scheduled a public hearing for 9:00 a.m. ET on June 3, 2026, at the Grimes County Justice & Business Center in Anderson, Texas. The court must approve the abatement for any tax relief to take effect. The proposed Terafab Texas site lies about 90 miles northeast of Austin and 20 miles east of Bryan-College Station.
Project Scale and Strategic Context
The filing proposes an initial investment of $55 billion, with a full multi-phase build-out estimated at up to $119 billion. It describes Terafab Texas as a next-generation, vertically integrated semiconductor manufacturing and advanced-computing fabrication campus. The initial figure exceeds the $52.7 billion authorized by the U.S. CHIPS Act, and the total estimate approaches the scale of Taiwan Semiconductor Manufacturing Co.’s Arizona campus.
Elon Musk first announced Terafab as a $20 billion project in March 2026. In April 2026, he said SpaceX would handle high-volume chip manufacturing while Tesla would operate a smaller research and development pilot line at its Austin campus. Analysts modeling a one-terawatt annual compute target estimate that achieving it would require about $5 trillion in capital and up to 358 fabrication sites, making the project’s total estimate a fraction of that broader industry buildout. Market tickers referenced in filings include P-SPAC and Tesla (TSLA).
The application presents an unusually large industrial capital plan before a local government. If approved and executed at scale, it would rank among the largest single-project chip-manufacturing proposals in the U.S., with significant implications for Musk’s technology businesses’ long-term supply strategies.
