SpaceX Plans $119 Billion 'Terafab' to Forge Chips in Texas

Elon Musk’s SpaceX is proposing to spend an initial $55 billion on a new semiconductor production facility in Grimes County, Texas, a project that could swell to $119 billion and mark a major push toward vertical integration for the billionaire’s corporate empire.

“The only thing that we know is what we are sharing with each other,” Marie Egyed, Director of Operations for the community group Grimes County Citizens for Responsible Development, told local news outlet KBTX, highlighting resident frustration over the lack of official communication. “And that is the problem that we have with this county. They need to start sharing this information with us.”

According to a public notice posted on the Grimes County website, the project is a “next-generation, vertically integrated semiconductor manufacturing and advanced computing fabrication facility” located at the Gibbons Creek Reservoir. The notice outlines a multi-phase development, with an initial capital investment of $55 billion. A public hearing is scheduled for June 3 to consider a tax abatement agreement for what the county has designated “SpaceX Reinvestment Zone No. 1.”

The move signals a significant strategic pivot for Musk, potentially aiming to create a captive, high-performance chip supply for his sprawling interests in artificial intelligence (xAI), electric vehicles (Tesla), and space exploration (SpaceX). Such a facility would directly compete with established semiconductor foundries like TSMC and Samsung and could reshape the domestic US chip landscape.

A 'Transformative Investment' or an xAI Data Center?

While the public notice names Space Exploration Technologies Corp., confusion swirls in the rural Texas county, located about 20 miles east of Bryan-College Station. According to Egyed, Grimes County Judge Joe Fauth previously indicated the project involved xAI, not SpaceX, leading to speculation about whether the site is for a chip fab or a large-scale data center.

“If it’s xAI, they’re going to be doing a data center. If they do, you know, SpaceX comes, it’s going to be something completely different,” Egyed said in her interview with KBTX.

The county’s notice describes the project as a “transformative investment” aimed at expanding domestic semiconductor manufacturing, a goal aligned with the federal CHIPS Act. However, neither SpaceX nor Musk has made an official announcement, leaving residents and industry watchers to parse the few public documents. Details on the facility's capabilities, such as the process node for manufacturing or the types of chips to be produced, have not been disclosed.

Vertical Integration Meets Local Apprehension

Should the Terafab proceed as a semiconductor plant, it would represent one of the largest single business investments in Texas history and a powerful step toward Musk’s goal of controlling his own technology stack. By producing its own advanced computing chips, SpaceX and its sister companies could reduce their dependence on third-party suppliers like Nvidia or TSMC, potentially cutting costs and designing silicon tailored to their specific AI and autonomy needs.

This ambition, however, is running into local friction. The lack of transparency has created an information vacuum, fueling apprehension among Grimes County residents. The situation mirrors other instances where Musk’s fast-moving projects have clashed with local communities. In a separate case, 77 residents in central Texas near SpaceX's McGregor rocket-testing facility have filed a lawsuit seeking over $1 million in damages, alleging that “daily ground shocks” have damaged their homes. This history of conflict underscores the challenges SpaceX faces as it pushes its massive industrial footprint deeper into Texas.
