I plugged this prompt into Claude. The idea being where would I buy my retirement home to be in the thick of things. I wouldn’t mind living near Corpus Christi or even San Antonio. I might even consider Brownsville. Although East Texas is where I grew up.
Prompt: Elon is going to build a terrafab to build AI chips. Let’s try to front run where he will build it.
Use these parameters
1000 plus acres
100,000 plus permanent employees eventually.
Water
Power
Elon’s Elonville. Draw a line from Austin to Brownsville to Corpus Christi back to Austin. Use a fat marker so not exactly in that area.
Essentially he needs a big piece of land that can in the future have enough resources in the area to support a decent sized city. 400,000 to 1.2 million people.
Claude’s response,
Here’s the full intelligence brief and interactive map. Key findings:
What we know as of today: Terafab was officially announced March 21, 2026. The full-scale facility has no confirmed location yet — it’s described as “yet to be determined.” Musk has confirmed the full-scale Terafab requires thousands of acres and over 10 gigawatts of power, and that it “couldn’t possibly fit on the GigaTexas campus.”
The five candidates I’ve mapped inside your triangle zone, ranked:
SITE-01 — Atascosa/Frio County (93/100) — TOP PICK. The sweet spot. Massive flat ranch land available in bulk at low $/acre, ~70 miles south of San Antonio’s 2.5M labor pool, direct ERCOT grid access, Carrizo-Wilcox aquifer underneath, and squarely centered in your Elonville zone. I-35 freight corridor is a massive logistics plus. This is where I’d look first.
SITE-02 — Live Oak/McMullen County (88/100). Geographic midpoint between SA and Corpus on the Elonville axis. The Nueces River solves water. Oil & gas land culture means large block sales are common. Weakness: you’d be building Elonville literally from scratch — no existing workforce base.
SITE-03 — Bee/Refugio County (81/100). Beeville’s NAS auxiliary airspace + 45 miles to the Corpus port (critical for importing 90-ton EUV machines by ship) is a real differentiator.

Sites 04–05 have the Musk narrative (Laredo trade corridor, Starbase adjacency near McAllen) but serious water scarcity and weak grid infrastructure knock them down.
The wildcard: Water may be the bigger long-term concern over electricity — a midsized data center alone uses roughly 300,000 gallons per day, about the equivalent of 1,000 homes. A city-scale Terafab supporting 400K–1.2M people would dwarf that. Aquifer access is the hidden variable that may ultimately determine the winner.

Claude has ways of saving a PDF, but I was unable to figure out how to use it on this Iphone.
My belief is that the area near Corpus Christi would be the site. Far enough inland to be clear if hurricanes, enough water and close enough to the coast for shipping and it could be a decent place to live. While the weather is hot, it is not much worse than Austin. The hill country around Austin is prettier, but there are serious water and land problems there. The area not mentioned was land between Austin and Houston. Not bad land and it generally tends to have more water, and it would have more access to skilled labor.
The outside of Corpus Christi area would essentially be a new city, that might give some people pause. I doubt it would stop Elon.
