The Terafab project, a joint venture between Tesla, SpaceX, and xAI, was announced by Elon Musk as a planned chip manufacturing facility in Austin, Texas. Musk stated the facility aims to produce a terawatt of computing power annually. The project is estimated to cost at least $20 billion.
Why Musk Says the Terafab Project Is Necessary
Musk made the announcement during a livestream on X, citing a significant gap between current chip supply and future demand. He said existing manufacturers, including Samsung, TSMC, and Micron, collectively supply only about two percent of what Tesla and SpaceX require for future computing needs. “We either build the Terafab or we don’t have the chips,” Musk said during the event. “And we need the chips so we’re going to build the Terafab.”
Two Chip Types for Two Environments
The facility will produce two distinct categories of chips. The first targets terrestrial applications, such as powering Tesla’s Full Self-Driving system and Optimus robots. The second is a higher-powered, more durable chip designed specifically for use in space.
Space Ambitions and the Orbital Data Center
The space-grade chip connects to a broader SpaceX initiative. Earlier this year, SpaceX filed an application with the Federal Communications Commission to launch one million satellites. The stated goal is to create an “orbital data center” in low Earth orbit. This plan would represent a significant expansion of SpaceX’s existing Starlink satellite network.
“We either build the Terafab or we don’t have the chips. And we need the chips so we’re going to build the Terafab.”

Context: A Track Record of Ambitious Timelines
The Terafab announcement follows a pattern of large-scale commitments from Musk. However, several previous projects have not met their original targets. The Hyperloop transportation concept, a $40,000 price point for the Cybertruck, and fully autonomous driving capabilities are among the initiatives that did not materialize as initially described. The Advanced Technology Fab in Austin will serve as the starting point for the broader Terafab build-out, given that Tesla’s headquarters is already located there.
Future Outlook
Musk framed the Terafab as a step toward what he described as harnessing solar energy and building a “galactic civilization.” No construction timeline or completion date was provided during the livestream. The project’s scale and the involvement of three major companies suggest that artificial intelligence and computing infrastructure will remain central to Musk’s corporate strategy in the coming years.
