SpaceX files for a $55bn Texas semiconductor fab

The Terafab project sits alongside the existing Bastrop packaging operation. Combined, the two facilities could anchor a $119bn Texas chipmaking footprint. SpaceX has not yet disclosed the process technology Terafab will run, or the construction timeline.

SpaceX has filed paperwork for a semiconductor fabrication facility in rural Texas with a planned investment of approximately $55bn. Reuters reported the filing on Wednesday. The project, known internally as Terafab, would sit alongside the company’s existing chip-packaging operations in Bastrop and, on completed timelines, anchor a Texas chipmaking footprint with combined potential investment reaching $119bn.

The distinction between Terafab and Bastrop matters. The Bastrop facility, which began equipment installation in April 2026, is a packaging operation. It takes silicon dies that have been fabricated elsewhere, packages them, and ships them out as finished radio-frequency chips for Starlink user terminals. Terafab is something different: an actual fabrication facility, designed to produce silicon at process nodes rather than only package it.

That moves SpaceX into a different category of operation. Packaging is a smaller, faster, more capital-light business than fabrication. A fab requires cleanroom facilities, lithography equipment that costs hundreds of millions per unit, deep semiconductor process expertise, and construction cycles that typically run five to seven years. The $55bn Terafab figure is consistent with that scale of project.

The combined facility would, on completion, include silicon fabrication, advanced packaging including panel-level packaging, printed circuit board manufacturing, and a semiconductor failure-analysis lab. The combined Bastrop and Terafab footprint would become the largest PCB and panel-level-packaging facility in North America.

The strategic rationale is consistent with SpaceX’s broader pattern. Starlink ships hardware at volumes that make per-unit silicon cost a non-trivial line in the company’s economics. Owning the fab, the packaging, and the PCB manufacturing in a single integrated US facility removes the third-party supplier margin from each step in the production chain and gives SpaceX direct control of the supply timeline for components that cannot be substituted late in the build cycle.

Texas Governor Greg Abbott’s office has been actively supporting the Bastrop expansion. A March 2026 announcement from the governor’s office confirmed a Texas Semiconductor Innovation Fund grant to SpaceX. Terafab, on the available reporting, would be eligible for additional state-level incentives at scale, alongside any federal CHIPS Act support that survives the current administration’s review.

The headline figures break down as follows. Terafab itself: approximately $55bn. The Bastrop expansion, including a million-square-foot footprint expansion over three years, plus the planned PCB operations, plus the panel-level packaging and failure-analysis components: approximately $64bn additional. Combined: $119bn.

Two questions are unresolved on the public record. The first is which specific process technology Terafab will run. SpaceX has not disclosed it, and the most ambitious leading-edge nodes would require licensing or partnership with an existing process-IP holder.

The most likely initial focus is on advanced packaging and mature-node fabrication for Starlink-specific RF and ASIC components rather than on competing directly with TSMC at the leading edge. The second is timeline. SpaceX has not publicly committed to a Terafab construction start or operational date, only to the filing.

The geographic logic fits a wider US pattern. Apple’s recent foundry-diversification discussions with Intel and Samsung are the demand-side counterpart, and Intel’s hire of a senior Qualcomm executive to lead its new Client Computing and Physical AI Group is the design-side complement. Texas in particular has been attracting AI-infrastructure commitments at scale: Hut 8’s $9.8bn Beacon Point lease in Nueces County is the parallel data-centre commitment in the same state.

What is no longer in doubt is intent. SpaceX has, on Wednesday’s filing, committed to manufacturing its own silicon at Tier-1 fab scale. Whether the timeline holds, whether the process technology question is answered through partnership or in-house development, and whether the combined $119bn capital programme survives the next several quarters of competing demands on SpaceX’s balance sheet are the open questions. The filing itself is the news.
