SpaceX Plans $119 Billion Terafab Chip Factory in Texas to Power AI and Space Ambitions
SpaceX is laying the groundwork for what could become the most ambitious semiconductor manufacturing project in modern history. A proposal filed in Grimes County, Texas, reveals that Elon Musk's space company is considering an initial investment of $55 billion, with total spending potentially reaching $119 billion, to build a facility dubbed "Terafab."
The planned factory is described as a multi-phase, vertically integrated semiconductor manufacturing and advanced computing fabrication facility. It represents a dramatic expansion of Musk's vision beyond rockets and satellites into the foundational silicon that powers artificial intelligence, autonomous vehicles, and orbital data centers.
According to the filing, Terafab will manufacture chips for a wide range of applications. These include AI servers powering xAI's Grok models, satellites for SpaceX's Starlink constellation, the company's proposed data centers in space, autonomous Tesla vehicles, and Tesla's Optimus humanoid robots. Intel has already been roped into the effort, bringing decades of chipmaking expertise to the table.
Musk has been vocal about the global chip shortage hindering his companies' growth. "We either build the Terafab or we don't have the chips, and we need the chips, so we build the Terafab," he wrote recently. The billionaire has stated that the facility could eventually manufacture enough chips to provide one terawatt of power per year.
However, the project is still in its early stages. Musk noted that Grimes County is just one of several locations under consideration for the factory. The timing is notable as the combined SpaceX-xAI entity, valued at roughly $1.25 trillion, is reportedly preparing for a public offering in June.
Why It Matters
Terafab underscores a tectonic shift in the AI landscape: the companies building the most advanced models are now racing to own the entire stack, from silicon to software. If SpaceX succeeds, it could reduce dependence on Nvidia and TSMC while reshaping how compute infrastructure gets built. For enterprises watching the AI arms race, this signals that vertical integration may soon be the only viable path to scale.
