1 Terawatt: The Massive Output Target for Terafab

The global semiconductor landscape is undergoing a significant shift as two major aerospace and automotive entities pursue an unprecedented manufacturing goal. Elon Musk announced on October 20 that critical equipment suppliers have accelerated deliveries to support the Terafab project, a joint venture between Tesla and SpaceX aimed at producing advanced chips.

During a live broadcast of the Q3 2026 earnings call, Musk stated that the company targets volume chip production at the primary facility in Gibbons Creek, Texas, by the third or fourth quarter of 2028. He described this timeline as highly aspirational, noting that it carries significant uncertainty. The announcement confirms that ASML, the sole commercial supplier of extreme ultraviolet lithography systems, is moving equipment forward to meet these aggressive deadlines. Musk expressed appreciation for the suppliers who are accelerating these deliveries to make the timeline feasible.

Terafab is designed as a vertically integrated factory with a goal of manufacturing one terawatt of AI computing power annually. This facility will handle logic, memory, and advanced packaging in a single location. The project utilizes Intel's 14A manufacturing node technology, with Intel officially joining the venture in April 2026 to co-develop silicon fabrication methods. The first EUV tool is reportedly scheduled for delivery in mid-2027, though it remains unclear if this date reflects the newly announced expedited schedule.

Other key partners include Applied Materials, Lam Research, KLA Corporation, and Tokyo Electron, which provide front-end processing and control machinery. Tesla and SpaceX are also negotiating with approximately ten South Korean firms, including Hanmi Semiconductor and HPSP, for specialized packaging and annealing equipment. These chips are intended to power xAI clusters, self-driving vehicles, Optimus robots, and orbital data centers, reducing reliance on external foundries like TSMC.

Musk also outlined near-term computing goals for his AI companies, expecting 2.5 to 3 gigawatts of capacity by the end of 2026. He is highly confident in reaching a total of 13 gigawatts by the end of 2027, supported by a 440,000-GPU Nvidia Vera Rubin cluster coming online in Q2 2027. He claimed that once fully operational, Terafab's output could place it within the top 20 global GDPs from a single building, a figure comparable to Switzerland's economy.

Despite the ambitious scope, experts have questioned the 1 terawatt target. Gartner estimates total global AI-optimized data center capacity at roughly 44 gigawatts as of late 2026, which is only 4.4% of Terafab's planned output. While global AI capacity has grown by roughly 3.3x to 3.4x per year since 2022, the sheer scale of Terafab remains a significant challenge. The next step involves securing the remaining supplier contracts and finalizing the construction of the Gibbons Creek facility to meet the 2028 production goal.
