SpaceX has filed plans with Grimes County, Texas, for what could become the largest semiconductor manufacturing investment in American history: a vertically integrated chip fabrication complex called Terafab, with an estimated total cost of up to 119 billion dollars.

The filing, submitted to the Grimes County Commissioners Court ahead of a public hearing scheduled for June 3, reveals that SpaceX intends to spend an initial 55 billion dollars on the first phase of the facility. The site, designated near the Gibbons Creek Reservoir roughly 20 miles east of Bryan-College Station, would house a next-generation semiconductor manufacturing and advanced computing fabrication plant that the filing describes as a transformative investment in domestic chip production.

Elon Musk first announced the Terafab concept on March 21, outlining an ambitious vision to consolidate chip design, fabrication, lithography, memory production, advanced packaging, and testing under a single roof. The goal, Musk has said, is to produce more than one terawatt of artificial intelligence compute capacity per year, a figure he claims dwarfs current global output.

During Tesla's first-quarter earnings call in April, Musk framed the investment as a matter of necessity. He argued that the global chip industry cannot expand quickly enough to meet the demand Tesla will need for edge inference compute powering its vehicles and Optimus humanoid robots, nor the specialized semiconductors required for orbital AI infrastructure. All existing fabrication facilities on Earth, Musk claimed, produce only about two percent of what Tesla and SpaceX will eventually require.

That earnings call also revealed a critical partnership. Musk confirmed that Terafab will use Intel's forthcoming 14A process technology, a next-generation chipmaking node expected to reach production readiness in 2027. "Intel is excited to partner with us on some of the core manufacturing technologies," Musk said during the call. Intel CEO Lip-Bu Tan had previously warned that the company could exit chip manufacturing altogether if it failed to land an external foundry customer, making the Terafab deal a potential lifeline for the struggling chipmaker.

Intel announced its formal involvement on April 7, saying it would contribute manufacturing expertise to help design, fabricate, and package ultra-high-performance chips at scale. The arrangement appears to be a technology licensing deal, with SpaceX responsible for high-volume manufacturing operations using Intel's process designs.

The scale of the investment is staggering even by semiconductor industry standards. Taiwan Semiconductor Manufacturing Company, the world's dominant contract chipmaker, has committed roughly 65 billion dollars to its Arizona expansion. Samsung's planned facility in Taylor, Texas, carries a price tag of approximately 17 billion dollars. At 119 billion dollars fully built out, Terafab would exceed both combined.

Industry analysts have raised questions about the feasibility of the timeline and the sheer capital required. Building a single advanced semiconductor fab typically takes three to five years and costs between 15 and 30 billion dollars. Musk's proposal envisions something far more complex: a vertically integrated campus that handles every stage of chip production, from raw silicon to finished multi-chip modules.

The Grimes County filing also triggered local concerns. Residents near the proposed site have sought more information about the project's environmental impact and infrastructure demands. The filing includes a request for property tax abatements through a designated reinvestment zone called SpaceX Reinvestment Zone No. 1, a standard incentive mechanism for large industrial projects in Texas but one that has drawn scrutiny given the scale of the proposed development.

At the June 3 hearing, the Grimes County Commissioners Court will consider approval of the tax abatement agreement. Early reports indicate that the court took no immediate action following initial discussions, suggesting that negotiations over the terms remain ongoing.

The Terafab project sits at the intersection of several converging forces in the technology industry. The global AI boom has created unprecedented demand for advanced chips. The CHIPS and Science Act has channeled billions in federal subsidies toward domestic semiconductor production. And Musk's constellation of companies, spanning electric vehicles, space launch, humanoid robotics, and AI infrastructure, gives him both the motivation and the potential scale to justify an in-house chip supply chain.

Whether Musk can execute on a project of this magnitude remains an open question. His companies have a track record of setting audacious targets and frequently missing initial deadlines, though they have also delivered results that skeptics once dismissed as impossible. The Terafab filing transforms the project from a social media announcement into a concrete regulatory and financial commitment, one that Texas officials, Intel executives, and the broader semiconductor industry will be watching closely.

For Intel, the stakes are equally high. Securing a marquee foundry customer validates its pivot toward contract manufacturing under Tan's leadership and could determine whether the company remains a chipmaker or instead retreats to design alone. For Musk, Terafab represents the logical extension of a philosophy he has applied across his ventures: when the supply chain cannot keep up, build your own.
