SpaceX, Elon Musk’s space exploration company that now also houses his artificial intelligence venture xAI, is evaluating plans to build a massive semiconductor manufacturing facility in Grimes County, Texas, according to a proposal filed on the county’s website. The initial investment could reach $55 billion, with total spending over multiple phases potentially hitting $119 billion.
What the filing reveals
The document describes the project as a ‘multi-phase, next-generation, vertically integrated semiconductor manufacturing and advanced computing fabrication facility.’ Dubbed ‘Terafab,’ the facility is expected to involve resources from Tesla and chipmaking giant Intel. The goal is to produce chips tailored for AI servers, satellites, SpaceX’s planned orbital data center, autonomous Tesla vehicles, and robotics.

Musk has previously stated that the Terafab would eventually manufacture enough chips to provide 1 Terawatt of power per year. He argued that current semiconductor production cannot keep pace with the demands of his companies’ AI and robotics ambitions. ‘We either build the Terafab or we don’t have the chips, and we need the chips, so we build the Terafab,’ he wrote.
Why this matters
The filing underscores Musk’s aggressive push to secure computing power for xAI’s Grok series of AI models. It also aligns with his broader strategy to capitalize on AI compute demand by building data centers in space, a rationale he has cited for merging xAI with SpaceX. The combined entity is reportedly valued at $1.25 trillion and is expected to go public in June.

However, Musk noted in a tweet on Wednesday that Grimes County is only one of several locations under consideration for the factory, leaving room for the project to land elsewhere.
Industry implications
If realized, the Terafab would represent one of the largest private semiconductor investments in U.S. history. The involvement of Intel, a company already investing heavily in domestic chip manufacturing, signals a deepening collaboration between Musk’s ecosystem and traditional chipmakers. The facility could also have significant economic impact on rural Texas, creating thousands of construction and high-tech jobs.
Conclusion
The Terafab proposal highlights the escalating demand for specialized AI chips and Musk’s willingness to invest heavily in vertical integration. While the project remains in early stages and faces potential location changes, the filing provides the clearest public indication yet of the scale of Musk’s semiconductor ambitions.
