SpaceX will construct a $16.8 billion semiconductor fabrication facility in Grimes County, Texas, Texas Governor Greg Abbott announced Tuesday. The plant will employ 3,000 workers and marks the first aerospace prime contractor to bring advanced chip production fully in-house.
The facility consolidates SpaceX's reliance on Taiwan Semiconductor Manufacturing Company and Intel Custom Foundry, both of which currently supply radiation-hardened and high-reliability chips for Starlink satellites and Falcon avionics. Construction begins Q3 2025 with first-wafer production targeted for late 2027. The site sits 60 miles northwest of Houston, adjacent to existing SpaceX engine test facilities in McGregor. Grimes County offered a $420 million tax abatement over ten years, and the State of Texas contributed $180 million in infrastructure upgrades—power grid reinforcement and water reclamation systems capable of handling Class 10 cleanroom demands.
This move reshapes procurement risk across the defense-industrial base. SpaceX currently consumes an estimated 18,000 wafers per quarter for Starlink alone, with Pentagon contracts adding another 4,000 wafers for classified payloads. Bringing production stateside eliminates Taiwan Strait exposure and removes the 14-week lead time TSMC requires for space-grade silicon. It also creates pricing leverage: internal cost models suggest SpaceX can produce rad-hard chips at 40% below current supplier rates once the facility reaches steady-state yield in 2029. Lockheed Martin, Northrop Grumman, and RTX—all dependent on the same foundries—now face a competitor with captive supply and no allocation battles during geopolitical shocks.
The Texas site will fabricate 28nm to 7nm nodes, with future 5nm capability planned for 2030. SpaceX has hired former TSMC VP of Operations Chen Wei-Lun to lead the plant, alongside 12 senior process engineers from Samsung Austin. The company filed 87 patents related to satellite-specific chip architecture between 2022 and 2024, suggesting proprietary designs incompatible with merchant foundry roadmaps. This explains the capital outlay: custom tooling from ASML, Applied Materials, and Lam Research accounts for $9.2 billion of the total spend, per filings reviewed by the Texas Comptroller's office.
Allocators should track three developments. First, SpaceX's CHIPS Act application—submitted in parallel with the Texas announcement—could unlock $2.8 billion in federal subsidies by October 2025. Second, Intel's Foundry Services division reports earnings May 15; any mention of SpaceX contract non-renewals will confirm the shift. Third, Taiwan's Ministry of Economic Affairs publishes export data June 10, where a decline in aerospace-category wafer shipments to the U.S. will quantify the displacement.
SpaceX stock closed Monday at $138.50, up 23% over five sessions and now trading above its April IPO price of $135 for the first time since mid-July. The semiconductor plant was not disclosed in the S-1 but appeared in a January 2025 investor update as "Project Longhorn." Insiders with knowledge of the buildout expect Musk to announce similar facilities for Tesla's Dojo chips and Neuralink ASICs within 18 months.
