SpaceX has filed plans for “Terafab,” a proposed semiconductor manufacturing facility in Grimes County, Texas. Multiple outlets report that the initial investment is estimated at about $55 billion, according to a public notice or filing. Other reporting indicates the overall project cost could rise if additional phases are built, with a total capital investment estimate of about $119 billion. The filings also describe the project as producing chips targeted at applications such as artificial intelligence, robotics, and data centers, including those used in space-related and ground-based systems. Some coverage adds that the facility would be run jointly by Tesla and SpaceX, reflecting Musk’s broader technology initiatives, though details may be limited to what is stated in the notices. One outlet notes the proposed Terafab project is separate from (and could complement) an existing SpaceX packaging operation in the area, suggesting the semiconductor footprint in Texas could expand beyond the initial fab. SpaceX has not publicly specified the process technology for Terafab or provided a detailed construction timeline in the reports reviewed.
