Build the Terafab semiconductor facility in Grimes County, Texas
SpaceX and Tesla announced Terafab, a vertically integrated semiconductor facility of more than 100 million square feet planned for Grimes County, Texas. No completion date has been stated.
Announced
What do the status labels mean?
Announced: it has been said out loud, but we have not seen work toward it yet.
In progress: we can point to tests, hardware or contracts that show work under way.
Partially achieved: part of the job is done and shown, but not all of it.
Achieved: evidence matches the whole “done” description we wrote down.
Uncertain: sources disagree or are missing. We say so instead of guessing.
Paused or cancelled: a reliable source says work has stopped or the plan was dropped.

What is a target window?
A target window is when the company said something would happen. Sometimes that is an exact day. Often it is only a month, a quarter or a year.
We keep it exactly as vague or as precise as the company did. If they said “2026”, we show 2026. We never turn that into a made-up day in December.
When a company gives a new date later, we keep the old one too. You can always see how the plan moved.
Saying “I’ll visit this summer” is a window. Saying “I’ll visit on 14 July” is an exact date. They are not the same promise.

Who checked this, and how?
Each record has a review note. It names who did the check and lists every claim that was compared with its source.
Right now these checks were done with AI help and have not yet been re-read by an independent human editor. We say this plainly on every page rather than hiding it.
A “review due” label means the record is older than two weeks and is scheduled for another look. The content is unchanged until then.

What would count as “done”
The Terafab facility in Grimes County begins manufacturing, packaging and testing advanced logic and memory devices, as recorded by a primary source.
Why we say this
The 6 August 2026 announcement states the site selection and the planned scale of the facility. It describes an earlier Tesla groundbreaking in April on a research fab at Giga Texas, which the announcement calls the precursor to Terafab, not Terafab itself. No construction start, completion date or production date for the Grimes County facility is stated.
Stated uncertainty. The announcement headline refers to breaking ground, but the groundbreaking it describes is the Tesla research fab at Giga Texas. This site does not treat the headline as evidence that construction has started in Grimes County.

What actually happened
We have not yet recorded anything that happened towards this promise. That describes our evidence, not the company: things may have happened that we have not written up yet.
Sources In plain EnglishWhere does the evidence come from?
Every status links to the page we read. We record who published it, when, and which part of it supports the claim.
A company saying something proves that the company said it. It does not prove the thing is true. When we can, we look for a second voice: a regulator, a partner like NASA, or an exchange.
If a page disappears later, we flag it. A missing page is not proof that a claim was wrong.

Claims we compared with their sources
The Terafab facility will be built in Grimes County, Texas, with more than 100 million square feet of manufacturing space planned.
Site and planned scale are stated. No construction or production date is given, so the target is recorded as unknown.
Ground has been broken on Terafab in Grimes County.
The headline says breaking ground, but the body describes an April Tesla groundbreaking on a research fab at Giga Texas described as Terafab's precursor. The milestone record states this discrepancy rather than repeating the headline.
What this check could not tell us
- This is an AI-assisted review, not independent human review.
- No SEC filing has been retrieved. Claims here rest on the company's press release and the exchange's newsroom article, not on filed documents.
- Nasdaq is the listing venue and is not a disinterested observer of its own listing, though the fact that trading opened is straightforwardly checkable.
Conflicting evidence
- Reported figures for the amount raised and the implied valuation differ between sources seen during research. Nasdaq's newsroom states $75 billion raised and an implied valuation of approximately $1.77 trillion, while other reporting cited larger figures. No amount or valuation is published on this site, and the conflict is recorded rather than resolved.
