TeraFab Texas: Grimes County Factory and Austin Research Fab

Last updated: October 13, 2026. TeraFab has two Texas locations in public reporting: a smaller Tesla research fab near Giga Texas in the Austin area and a planned 100-million-square-foot production complex in Grimes County near the Gibbons Creek Reservoir. This page tracks verified milestones and separates visible construction activity from proposed dates and long-term targets.

Where is TeraFab located?

Austin-area research fab

Tesla began work on a semiconductor research facility at the North Campus of Giga Texas. The Austin-area facility is intended to test ideas, processes and small-batch production. Musk previously described capacity of a few thousand wafers per month.

Grimes County production complex

The announced large-scale TeraFab complex is in Grimes County, Texas, near the Gibbons Creek Reservoir. Reuters reported that the facility is planned to make, package and test advanced logic and memory chips. Water for industrial operations is expected to come from the reservoir rather than local groundwater.

The locations serve different functions. The research fab is intended to learn and qualify. The Grimes County complex is intended to scale.

Verified TeraFab timeline

What has been announced for Grimes County?

• An initial investment of $16.8 billion by SpaceX and Tesla.
• A long-term footprint of about 100 million square feet.
• At least 3,000 jobs.
• Manufacturing, packaging and testing of advanced logic and memory chips.
• Processors for Tesla Optimus and Cybercab applications.
• High-power chips for SpaceX’s space-based computing plans.
• Industrial water sourced from the Gibbons Creek Reservoir.

These are announced plans. Readers should not describe the jobs as filled, the full footprint as constructed or the chips as shipping until evidence supports those statements.

What is happening at Giga Texas?

The research fab is a precursor rather than a miniature copy of the full vision. It can help engineers test process integration, tool configurations, packaging and design feedback. Research output can also reveal whether the proposed Intel 14A route and product designs are practical.

The most important research-fab milestones would be installed equipment, first test wafers, process qualification, yield data and a named chip entering product validation.

When will TeraFab start production?

No single dependable date applies to the entire program. A research line can begin experimental work before the full production complex is built. The Grimes County site is also planned in phases.

Forecasts should distinguish:

1. research equipment installation;
2. first test wafers;
3. pilot production;
4. product qualification;
5. early commercial output; and
6. full multi-phase capacity.

A groundbreaking or completed building is not the same as qualified semiconductor production.

Power, water and infrastructure questions

The Grimes County plan is large enough to make utilities central to the schedule. Semiconductor equipment requires dependable power, cleanroom cooling, specialty gases and ultra-pure water. Packaging and testing add further infrastructure.

Key documents to monitor include water agreements, discharge permits, air permits, power-interconnection filings, construction permits and tax-abatement performance requirements. These records provide stronger evidence of progress than promotional renderings.

The trademark dispute

In September 2026, Tom’s Hardware reported that Tera-Print had challenged the TeraFab name, arguing that it had used the Tera-Fab brand for lithography tools for years. The report said the parties had discussed settlement and that a lawsuit was being pursued.

This is a naming and trademark issue, not proof that the semiconductor plan has failed. Possible outcomes could include a settlement, coexistence, licensing or rebranding. Until court records or company statements resolve it, the dispute should be described as pending.

What to watch next

• Final agreements among SpaceX, Tesla and Intel.
• Major construction permits and utility commitments.
• Tool orders and installation at the research fab.
• First test wafers and disclosed process results.
• Grimes County construction milestones.
• Environmental and water documentation.
• Updates to investment scope or phase timing.
• Resolution of the TeraFab trademark dispute.
• Identification of a production AI5, AI6 or D3 chip.

Confirmed facts versus projections

Frequently asked questions

Is TeraFab in Austin?

The research fab is near Austin at Giga Texas. The announced large-scale production complex is in Grimes County.

Has construction started?

Yes, at an early stage. Tesla began work on the Austin-area research facility, and aerial reporting published September 29 showed active land clearing at the Grimes County site. That verifies site preparation, not completed cleanrooms, installed semiconductor tools or commercial production.

When will chips ship?

No reliable large-scale shipment date has been established publicly.

Will the name change?

A trademark dispute has been reported, but no final outcome has been established.
