You've heard of Austin's tech boom. But what's quietly happening in the counties surrounding Austin right now is something on a different scale entirely — and it matters for everyone in this region.
Elon Musk is building a vertically integrated industrial empire across Central Texas, and the scope of it is becoming clearer by the month.
The Bastrop Beachhead
It started modestly enough in 2021 with The Boring Company setting up headquarters at the corner of Walker Watson Road and FM 1209, about 30 miles east of downtown Austin near Bastrop. That foothold has since expanded to include the headquarters of X (formerly Twitter), the Boring Bodega, a University of Austin engineering lab, and an elementary school. Then SpaceX arrived.
SpaceX debuted on the Austin Business Journal's list of largest area employers this year with 1,590 employees as of March — a number that's already bigger and heading toward 2,000. For context, only H-E-B employs more people in the Austin area. Tesla, already the region's second-largest employer, isn't even counted in those SpaceX numbers.
The centerpiece of what's coming is what Musk calls the Gigasat — an 11-million-square-foot solar production and AI satellite manufacturing campus stretching along FM 1209. That's larger than the Tesla Gigafactory east of Austin, which itself is roughly 10 million square feet. The Gigasat will vertically integrate everything needed to build orbital data centers: solar ingots and wafers, solar cells, printed circuit boards, AI satellite production, user terminals and gateways — all on one campus. Musk aims to have AI satellite production operating "at some reasonable volume" by end of 2027 and is targeting 1 gigawatt of orbital AI compute capacity by then, with a goal to scale 100 times beyond that within three and a half years.
In July, property records showed Musk had tripled his land holdings in Bastrop County — acquiring more than 1,360 additional acres since May alone, pushing his total there to roughly 2,000 acres. No permits have been filed yet for the new land, but with Musk's track record, the silence is temporary.
Terafab: The Grimes County Wildcard
Farther out — near College Station in Grimes County — an even larger gambit is taking shape. Musk has proposed Terafab, a joint venture between SpaceX, Tesla, and xAI, at the site of the former Gibbons Creek Steam Electric Station. The first phase would see $55 billion invested; fully built out, Grimes County puts the total investment figure at $119 billion. Terafab would manufacture semiconductor chips at a scale described as "1 terawatt" of compute — potentially hundreds of millions of chips per year destined for Optimus robots, self-driving vehicles, and AI satellites. Texas A&M's Semiconductor Institute director put it bluntly: it could be "amongst the largest [factories] ever built." Grimes County approved the reinvestment zone, and land acquisition by an xAI-linked entity is already underway.
Tesla Keeps Spreading Out
Back in Austin proper, Tesla just leased the 682,000-square-foot Austin Hills Commerce Center on Decker Lake Road — the largest speculative industrial building ever built in the Austin region — bringing its total leased footprint to nearly 2.9 million square feet across the market, on top of the 10+ million square feet it owns outright. And right next to the Gigafactory, Tesla is under construction on an Optimus humanoid robot factory that Musk has called "not just Tesla's biggest product, but the biggest product ever."
What This Means for You
The thread connecting all of it is Musk's stated goal: civilizing space. Bastrop makes satellites and solar power. Grimes County makes the chips. Austin makes the robots and the cars. The orbital data centers go up in 2027.
From a real estate perspective, the ripple effects are already being felt. Industrial demand in the Austin region is surging, with developers scrambling to build "bomber buildings" — structures over 500,000 square feet — just to keep pace. The workforce being recruited into these facilities spans engineering, advanced manufacturing, and logistics — well-paid jobs that drive housing demand across Travis, Bastrop, and surrounding counties.
Whether you're a fan of Musk or not, the economic gravity of what's being built here is real. Central Texas is becoming the manufacturing backbone of the next technological era — and that's worth watching closely.
