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
No new SpaceX statement about Terafab, the circumlunar flight or the Mars flyby has been published since 18 September 2026.
Only the 15 September and 8 October updates are newer. Secondary reports of Terafab site clearing exist but no primary source, so the record is unchanged.
What this check could not tell us
- AI-assisted review drafted on 14 October 2026 for owner approval before publication; not independent human review.
- Flight 14 outcomes rest on SpaceX's own mission page; no independent tracking or regulator source was checked for the flight.
- The 2025 Florida launch count comes from Launch Library 2, an aggregator, with the range operator's all-provider total as corroboration. SpaceX has published no year-end figure.
