Semiconductor Acceleration: Musk Claims Suppliers Rushing Gear for Terafab

Elon Musk confirmed on October 20 that critical semiconductor equipment suppliers, including ASML, have agreed to expedite shipments for the Terafab project. This acceleration is intended to support the ambitious timeline for the joint chip manufacturing facility developed by Tesla and SpaceX.

The primary goal is to achieve volume chip production at the main facility in Gibbons Creek, Texas, by the third or fourth quarter of 2028. Musk described this schedule as "highly aspirational," noting that it carries significant uncertainty and "big error bars." He expressed gratitude to ASML and other partners for accelerating equipment deliveries to help achieve this outcome.

A key milestone in this process involves the delivery of extreme ultraviolet (EUV) lithography systems. ASML is the world's sole commercial provider of these machines, which cost approximately $400 million each and are essential for leading-edge chip production. Unofficial sources indicated that the first EUV tool was originally slated for delivery in mid-2027. It remains unclear if the recent announcement confirms that this specific date has been moved up, though the broader supply chain is already tight.

Beyond ASML, the project relies on a diverse group of major suppliers to provide front-end processing, metrology, and process control machinery. These partners include American firms Applied Materials, Lam Research, and KLA Corporation, as well as Japan’s Tokyo Electron. Tesla and SpaceX are also in negotiations with about ten South Korean equipment manufacturers, such as Hanmi Semiconductor and HPSP, to secure specialized components like advanced packaging equipment and high-pressure hydrogen annealing systems.

The facility is designed as a vertically integrated plant that will manufacture logic, memory, and advanced packaging in one location. It will utilize Intel’s 14A manufacturing node technology, with Intel having joined the venture in April 2026 to co-develop the silicon fabrication process. The long-term ambition is for Terafab to produce one terawatt of AI computing power annually, a scale Musk suggests could give the single building a commercial value comparable to the GDP of the twentieth-largest country globally, which is Switzerland at approximately $1.14 trillion.

Contextually, this expansion occurs alongside other major AI infrastructure projects. Musk stated that his AI companies expect to have 2.5 to 3 gigawatts of computing capacity active by the end of 2026. He expressed high confidence in adding another 10 gigawatts in 2027, aiming for a total of 13 gigawatts by the end of that year. To support this, SpaceX and xAI are procuring next-generation NVIDIA architecture, with plans to bring a 440,000-GPU "Vera Rubin" training cluster online by the end of the second quarter of 2027.

The Terafab project is partly a response to anticipated shortages of cutting-edge AI processors from external foundries. The chips produced will supply xAI’s clusters, Tesla’s self-driving vehicles and Optimus robots, and SpaceX’s orbital AI data center. However, analysts have questioned the feasibility of the one-terawatt target. Research firm Gartner estimates the total global AI-optimized data center capacity is roughly 44 gigawatts as of late 2026, meaning Terafab’s planned output would be significantly larger than the entire current global total.
