Construction is seen north of the Tesla Giga Texas factory in Austin on Wednesday, March 25, 2026. CEO Elon Musk said Tesla and SpaceX are planning the world’s largest chip manufacturing plant, called Terafab, but said this site would be used ...
Tesla has announced plans to build a major semiconductor fabrication facility called Terafab in Austin, Texas, in partnership with SpaceX, to secure advanced AI chip supplies for its vehicles, robotics, and data center projects.
Elon Musk Announces Massive 'Terafab' Chip Factory in Austin to Power Tesla AI, SpaceX Satellites and Robotics
Speaking in Austin, Musk described the Terafab concept as an effort to materially expand computing supply for artificial intelligence, robotics and space applications, areas he indicated may require far more silicon than is currently available. Estimates referenced by analysts suggest the project could involve $5 trillion to $13 trillion in capital spending, supporting hundreds of fabrication plants and targeting up to one terawatt of annual compute capacity, a scale that may rival or exceed tod
Development Elon Musk announces 'largest chip manufacturing facility' Terafab coming to Austin
Musk is planning to build a massive new chip plant in Austin. The facility will be built near Tesla's Giga-factory.
SpaceX has separately asked the Federal Communications Commission for authorization to launch up to one million satellites into low Earth orbit as part of an orbital data center network. Musk frames Terafab as the chip supply chain for that constellation.
Musk on Saturday announced what he calls the “Terafab,” a semiconductor manufacturing plant to be located in Austin, Texas, that will produce chips for Tesla vehicles, SpaceX spaceships and Optimus humanoid robots.
Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry ... Ives calls Terafab the “first step” toward full operational integration.
I’ve written in detail about how market entertainer Elon Musk has been cannily adding the narrative evolution of ‘AI Space Data Centers’ to bolster his planned June mega-IPO of SpaceX/xAI around his birthday. Now it’s being bolstered with a new layer called ‘Terafab’, which is yet another fantastical tale of whole new ways to make chips in the US.
Now, he’s adding cutting-edge chip fabrication to the list to tie them all together. His new Terafab project between Tesla, SpaceX, and xAI aims to produce 50x the world’s current global compute per year, most of it deployed on AI satellites in orbit — in what Musk called the first step ...
The total cost of the project is estimated at up to $25 billion, with construction planned at Tesla’s Giga Texas site.
SK Hynix plans to spend $7.9 billion on EUV lithography tools from ASML through 2027, one of the largest orders of its kind. Musk’s Terafab has launched a talent war in Taiwan, recruiting senior chip engineers with its 2-nm fab plan targeting TSMC.
Terafab is planned as a 200,000-square-foot facility capable of 12-inch wafer processing at sub-10nm nodes. Key technical elements include: Cleanroom Environment: ISO Class 1 to Class 5 cleanrooms with humidity, temperature, and particle control maintained within ±0.1°C and ±1% RH to ensure process consistency. Process Technology: Advanced EUV lithography machines from ASML targeting 5nm and 3nm logic processes, coupled with deposition and etch modules from Applied Materials and Lam Research.
TSMC’s competitive moat isn’t just their EUV machines, it’s the ten thousand process engineers who have collectively seen every failure mode and built the tacit knowledge base to diagnose them. That institutional knowledge takes years to accumulate and cannot be hired away in bulk. Tesla is starting from zero on this. The early years of Terafab production, if it reaches production at all, will be characterized by poor yields and negative margins.
Yet building a fabrication plant ... challenge. Terafab must not just produce chips; it must become a factory of innovation, scaling to 100–200 billion units annually. A key technological bottleneck is ASML's dominance in extreme ultraviolet (EUV) lithography....
The prospect of a Terafab-driven capital raise — at a time when the stock is already under pressure — is the single biggest near-term fear weighing on TSLA. Building a leading-edge semiconductor fab involves over 2,000 individual manufacturing processes, globally scarce EUV lithography equipment (with 2+ year lead times from ASML), and engineering talent that TSMC has spent 30 years cultivating.
The most visible bottleneck is equipment. EUV lithography tools—dominated by ASML—carry multi-year backlogs, and allocation tends to favor established customers with proven ramp capability. Beyond EUV, a high-volume fab requires a dense ecosystem of deposition, etch, inspection, metrology, and test equipment, each with its own supply constraints and service needs.
