Terafab could become the largest factory on the planet—or Elon Musk’s biggest failure

FastCompany: At last, we know how Elon Musk’s fabled Terafab will look . Tesla and SpaceX showed a video rendering of their jointly developed advanced chip factory on Thursday. It will occupy 100 million square feet in Grimes County, Texas, about 45 miles northwest of downtown Houston. The sci-fi-looking building is so vast that you could fit six of them in Manhattan. Musk, the CEO of both companies, took to X on Thursday to declare it “the largest and most valuable building on Earth by far.” Except, you know, it doesn’t actually exist.

As with so many of Musk’s grand projects, like the ones he used to sell his inflated SpaceX IPO , this is just a megacool gigafuturistic terarender. Musk’s brand is the epic announcement, and the Terafab launch does not disappoint in that regard. The factory’s website labels itself as “the most epic chip-building effort ever.” It is a cosmic vision, sold as imminent, wrapped in renderings. The question isn’t whether Terafab will ever be real; it’s whether it will be this Terafab, on this schedule, at this size. The foundations for an exciting future are being built in Texas.

SpaceX says the facility will be “an advanced semiconductor fab that will bridge the divide between current global chip supply and the compute demand of the future.” A vertically integrated factory putting manufacturing, packaging, and testing of advanced logic and memory under one roof, the company claims “Terafab will be epic in both its mission and in its sheer size.” The chips will be optimized for edge computing and inference, destined for Tesla’s Optimus robots and self-driving Cybercabs , while additional hi

gh-power chips will sustain SpaceX’s space-based data centers. Intel is participating, though Intel won’t say what its role is. SpaceX promises to employ at least 3,000 workers from Grimes and neighboring Brazos counties, and says it’s “committing to the use of” water from the local Gibbons Creek Reservoir rather than local groundwater. According to Bloomberg, the fab (semiconductor fabrication plant) will be powered by natural gas power plants that SpaceX will build itself.

“We are bringing our own power,” Riley Trettel, SpaceX’s head of energy and data center development, told residents at a public meeting Wednesday—plus “very large battery arrays.” Solar power is nowhere in the plans, even though project partner Tesla is itself a solar manufacturer. SpaceX, freshly public after raising $87.5 billion in its IPO, got a 100% tax abatement from Grimes County—contingent on spending at least $5 billion by 2030 and creating at least 1,800 full-time jobs by 2035—plus $30 million in state incentives.

The news landed one day after hundreds of residents packed a county meeting Wednesday to protest those millions in tax breaks and what they saw as insufficient transparency. The Texas Governor’s office put out a statement endorsing the deal from Dr. Sarah Borowicz, superintendent of the Anderson-Shiro Consolidated Independent School District, promising every opportunity would be managed “wisely, transparently, and always with students at the center of every decision.” Still, the price keeps shifting. Terafab was unveiled in March as a $25 billion factory, then slated at $55 billion in later filings.
