Elon Musk took the stage at Austin’s historic Seaholm Power Plant on Saturday to unveil what he called “Terafab” – a huge semiconductor manufacturing plant that, if pulled off, would be the largest chip production facility ever built.
Beams of light shot into the Austin sky as Musk described the project to an audience of the Lone Star State’s tapped-in leaders, which included Texas Gov. Greg Abbott. The announcement capped off a week of speculation after Tesla first teased the ambitious and complex project on X, describing it simply as “the next step towards becoming a galactic civilization.”
“One Hell of a Building”: Tesla, SpaceX, and xAI Team Up to Create Terafab
According to Tesla’s official announcement, the proposed Terafab manufacturing facility would aim to produce one terawatt per year of AI computing capacity – all under one, very big, roof. Tesla also claims it will target producing 100 to 200 million advanced AI chips annually, using its cutting-edge new “nanometer process technology.”
The project is a three-way collaboration between Tesla, SpaceX, and xAI.
Tesla has stated that the proposed facility by their team is designed to supply chips for their Full Self-Driving systems, their Optimus humanoid robot program, xAI’s artificial intelligence infrastructure, and even SpaceX’s constellation of solar-powered AI satellites they plan to launch into orbit.
In another post, Tesla wrote: “Together with SpaceX & xAI , we’re building the largest chip manufacturing facility ever – combining logic, memory & advanced packaging under one roof. To harness as much power as possible from the Sun, we need to send 100 million tons of solar capture into space – per year…We’re building TERAFAB to close the gap between today’s chip production & the future’s demand – a future among the stars.”
The first phase of Terafab will reportedly begin with an advanced technology fabrication facility at the Giga Texas site, Tesla’s existing campus in Travis County. The full-scale Terafab site, however, Musk said, will require thousands of acres and is still being designed – with multiple different locations under consideration.
Tesla posted an illustration comparing the planned Terafab site to the current Gigafactory Texas, which is roughly 1 mile long and has about 10 million square feet of floor space. For scale, TERAFAB is projected to reach around 100 million square feet in total – roughly 10 times larger than the main Giga Texas building.
“That will be one hell of a building!” Musk said.
Tesla’s CFO, Vaibhav Taneja, said on an earnings call that the $20–25 billion price tag for Terafab isn’t yet baked into the company’s 2026 capital spending plan.
Terafab Boosts Austin’s Growing Status
The announcement boosts Austin’s already-huge role in Musk’s industrial footprint.
As The Dallas Express has previously reported, Tesla has been quickly expanding its autonomous vehicle plans in the city. From the early supervised FSD ride-hailing pilot launched in April 2025, to fully driverless Model Ys seen on Austin streets last December, to Cybercab production now underway at Giga Texas, progress has been notable.
The company has also discontinued the Model S and Model X earlier this year as it pivoted even more resources toward the robotics programs and FSD research teams.
“Thanks Elon. Extraordinary event tonight,” Abbott wrote via X on Sunday. “Your vision is powerful and we are proud of all you do in Texas.”
Terafab Born Out of Necessity
The global chip shortage driving the Terafab announcement is not breaking news. Tesla has expressed frustration with the pace of its external chip suppliers for over a year now.
“We’re very grateful to our existing supply chain, to Samsung, TSMC, Micron and others,” Musk said at the Seaholm event, “but there’s a maximum rate at which they’re comfortable expanding.”
“We either build the Terafab or we don’t have the chips, and we need the chips, so we build the Terafab,” Musk added.
Thousands of High-Skilled Jobs vs. Huge Power and Water Strain
While the Terafab’s potential economic impact is undeniable – bringing thousands of high-skilled jobs and strengthening Texas’s growing semiconductor corridor alongside Samsung’s Taylor plant and TI’s Sherman facility – it may also place considerable strain on the state’s infrastructure.
Chip fabrication is among the most resource-intensive industrial processes on the planet.
Even a small-scale facility consumes enormous amounts of electricity continuously, and semiconductor fabs are notoriously water-hungry, relying on ultra-pure water for every stage of production. A facility targeting the size of Terafab that Musk described would dwarf anything currently operating in the state.
Texas already faces documented strain on both fronts.
State law now requires big power consumers to consult with grid operator ERCOT before moving forward, and data centers and AI facilities have been steadily adding load to a grid that has previously seen some major scrutiny, specifically after the mess of management during the 2021 winter storm.
The full-scale Terafab, which Musk acknowledged would require a separate site with thousands of acres, would need not just land, but also a dedicated power solution – something the project has not yet publicly addressed in detail.
Water is another big concern.
State planners don’t really have a clear picture of how much water data centers and AI facilities are already drawing from Texas’s aquifers and municipal systems. A chip fab at Terafab’s proposed size adds to the uncertainty.
Some Texas cities are already facing a water scarcity crisis. As recently covered by The Dallas Express, Corpus Christi’s water supply is rapidly declining, with officials expecting a “water emergency” by November and potentially even running dry by 2027.
From Skeptics to Success
Musk provided no firm construction timeline at the Seaholm event. However, early chip production could begin as soon as 2027, with mass production targeted for 2028.
Musk compared Terafab’s critics to Tesla’s early skeptics and SpaceX’s critics of reusable rockets; projects he pointed out have ultimately succeeded. He also brought up his infatuation with sending humans to Mars, saying, “We want to be a civilization that expands to the galaxy…Cities on Mars. Populate the solar system.”
Whether Terafab becomes another unlikely success or a cautionary tale will likely be decided right here in Texas.
