SpaceX, Elon Musk’s space company that also houses his AI company, xAI, is considering spending $55 billion, at least initially, to build a semiconductor factory in Grimes County, Texas, according to a proposal(1).pdf) on the county website.

The company estimates it may spend a total of $119 billion on the project, which would be a “multi-phase, next-generation, vertically integrated semiconductor manufacturing and advanced computing fabrication facility,” according to the filing.

Musk has previously outlined plans for the project, dubbed “Terafab,” that will also see Tesla contributing resources. The companies have roped chipmaking giant Intel into the effort, aiming to develop chips for AI servers, satellites, SpaceX’s proposed data center in space, as well as autonomous Tesla vehicles and robots.

The billionaire has said the manufacturing facility will, sometime in the future, manufacture enough chips to provide 1 Terawatt of power per year, arguing that semiconductor manufacturers aren’t making chips quickly enough for his companies’ artificial intelligence and robotics needs. “We either build the Terafab or we don’t have the chips, and we need the chips, so we build the Terafab,” he wrote.

However, Musk wrote in a tweet on Wednesday that Grimes County in Texas was only one of several locations under consideration for the factory.
