Terafab Plans Texas Chip Fabs for Tesla, SpaceX
The $16.8 billion Grimes County site is planned for production, while the Austin research fab is still in early build.
Updated on Nov. 7, 2026 in Semiconductors
Tesla and SpaceX have revealed Terafab, a joint semiconductor project announced by Elon Musk on March 21, 2026. The first piece is a research chip fab at Tesla's Giga Texas campus in Austin, with construction starting in April 2026, and Intel joined as a foundry partner on April 7, 2026. The project is in the build-out stage rather than a shipping product line.
Why it matters
Terafab signals that Tesla and SpaceX want in-house access to the AI chips their vehicles, robots and planned space-based data centers will require, rather than relying solely on outside foundries. Intel's entry as a manufacturer of chips designed by others points to a sourcing strategy that mixes captive and contract production.
The announced figures are a $3 billion research fab in Austin and a $16.8 billion initial investment in a 100 million square foot production site in Grimes County, with a stated long-term goal of 1 terawatt of annual AI compute capacity. These are project targets from the companies rather than measured results, and the timeline for reaching the compute goal has not been specified.
The players
Tesla
Electric vehicle maker building its own AI chips for vehicles, Optimus humanoid robots and Cybercabs.
SpaceX
Rocket and satellite company planning space-based data centers that will require its own AI hardware.
Intel
Established chipmaker joining Terafab as a foundry partner to manufacture chips on its 14A process node.
The details
A research fab is a pilot-scale chip factory used to test new designs quickly before committing to high-volume production. Terafab's first stage is that kind of facility at Giga Texas, while the larger Grimes County site is planned for full production. A foundry partner such as Intel manufactures chips designed by other companies, so Intel's role would be to fabricate Terafab designs on its 14A process node, a manufacturing generation that defines transistor sizes and layout rules.
Timeline
March 21, 2026: Elon Musk announces Terafab.
April 2026: Construction begins on the Giga Texas research fab.
April 7, 2026: Intel joins Terafab as a foundry partner.
The Tech Race
Terafab's Intel partnership ties Tesla and SpaceX's chip plans to Intel's 14A process node, placing them among companies seeking advanced foundry capacity. The source does not compare the project's capacity or timing against competing semiconductor efforts.
Terafab is not yet a product available to consumers, and the source gives no date for production chips reaching Tesla vehicles or robots. Texas residents may see manufacturing jobs in Grimes County as the projected 3,000 positions are filled, but the timing of that hiring is not stated.
The takeaway
Terafab is the clearest sign yet that Tesla and SpaceX intend to control their own AI chip supply rather than depend solely on outside foundries. Watch for the Grimes County production start date and any confirmed 14A tape-out with Intel, both of which would show whether the 1 terawatt goal is on track.
