Billionaire entrepreneur Elon Musk announced late Saturday that his high-stakes gamble on artificial intelligence hardware has a new home: Austin, Texas.
Speaking to a crowd at the historic Seaholm Power Plant in downtown Austin, Musk confirmed that a $20 billion chip fabrication facility, dubbed the “Terafab” will be constructed on the existing Tesla campus in eastern Travis County.
The announcement concludes a week of intense digital speculation fueled by Musk’s posts on his social media platform, X. The project is structured as a massive joint venture between three of Musk’s primary entities: Tesla, SpaceX, and the AI-focused xAI.
The Terafab is designed to address what Musk describes as a critical shortage in global computing power. Once operational, the facility is expected to produce 1 terawatt of compute annually—a capacity equivalent to roughly 100 million to 200 million AI chips.
According to Musk, these proprietary chips will serve as the "central nervous system" for his interconnected suite of technologies, including:
- Tesla’s Full Self-Driving (FSD) suites and Optimus humanoid robots.
- SpaceX’s sophisticated rocket guidance systems.
- xAI’s large-scale language models and synthetic intelligence research.
“Current fabrication facilities on Earth only produce about 2% of what we actually need,” Musk told an audience that included Texas Governor Greg Abbott.
While he acknowledged the efforts of current partners like Samsung Electronics—which is currently expanding its own footprint in nearby Taylor, Texas—Musk argued that industry growth is not meeting his aggressive timelines.
Thanks Elon.
Extraordinary event tonight.
Your vision is powerful and we are proud of all you do in Texas. https://t.co/ZIIREFrnhh

The decision to build in eastern Travis County further solidifies Central Texas as the primary hub for Musk’s industrial empire. By integrating chip manufacturing directly into the Tesla "Giga Texas" site, the venture aims to reduce supply chain dependencies that have historically slowed production for high-tech components.
“They won’t have the chips if they don’t build the Terafab,” Musk quipped during the event. “So, we’re gonna build Terafab.”
Construction timelines and specific job creation numbers were not immediately released, though a project of this scale is expected to bring thousands of specialized engineering and construction roles to the Austin metropolitan area.
