Semiconductor Ambitions: Musk Claims Suppliers Fast-Tracking Terafab Shipments

Elon Musk declared during a live broadcast on October 20 that major semiconductor equipment providers are moving faster to deliver machinery for Terafab, the joint chip manufacturing venture between Tesla and SpaceX. The announcement came during SpaceX's third quarter 2026 earnings call on X, where the CEO outlined the aggressive schedule for the facility located in Gibbons Creek, Texas. Musk stated that the project aims to begin volume production of chips by either the third or fourth quarter of 2028, though he described the timeline as highly aspirational with significant uncertainty.

The financial and operational stakes are immense. The facility is designed to be a vertically integrated factory producing 1 terawatt of AI computing power annually. Musk suggested that the commercial value of this output could rival the gross domestic product of a top twenty global nation. For perspective, Switzerland currently sits at the twentyeth place on that list with a GDP of approximately 1.14 trillion dollars. The plant will handle logic, memory, and advanced packaging internally, relying on Intel's 14A manufacturing node and extreme ultraviolet lithography systems.

Key partners in this supply chain include ASML, the sole commercial seller of the necessary 400 million dollar EUV tools, and Intel, which joined the venture in April 2026 to co-develop silicon fabrication technology. Other critical suppliers are American firms such as Applied Materials, Lam Research, and KLA Corporation, along with Japan's Tokyo Electron. Tesla and SpaceX are also negotiating with roughly ten South Korean companies, including Hanmi Semiconductor and HPSP, for specialized equipment and components. Musk noted that ASML and other vendors are accelerating deliveries to meet the 2028 goal, a claim that raises questions given the historical backlog of EUV machines.

Musk also detailed near-term computing expansions for his AI entities. He expects 2.5 to 3 gigawatts of capacity to be active by the end of 2026. He expressed high confidence in adding another 10 gigawatts in 2027, predicting a total of 13 gigawatts by the end of that year. To support this, SpaceX and xAI are procuring a massive 440,000-GPU Nvidia Vera Rubin training cluster, which is planned to come online by the end of the second quarter of 2027. This expansion is intended to serve xAI clusters, self-driving vehicles, Optimus robots, and SpaceX's orbital data center.

Skepticism persists regarding the scale of the 1 terawatt target. Research firm Gartner estimates the total global AI-optimized data center capacity at roughly 44 gigawatts as of late 2026. This figure represents only 4.4 percent of what Terafab plans to produce. While global AI computing capacity has grown by a factor of 3.3 to 3.4 annually since 2022 according to EpochAI, the gap between current global infrastructure and the projected output of a single Texas facility remains substantial. The project aims to reduce reliance on external foundries like TSMC, but the speed of the current supply chain adjustments will be the first test of its feasibility.

The first experimental test chip is scheduled for manufacture at SpaceX's research fab in Austin, Texas, around the second quarter of 2027. This milestone will provide an early indication of whether the accelerated equipment deliveries are sufficient to meet the broader production targets. The success of Terafab will depend on the coordination of multiple international suppliers and the ability to integrate advanced lithography and packaging technologies within a compressed timeframe.
