Terafab Aims for 2028 Chip Production as Suppliers Accelerate Deliveries

Elon Musk has stated that critical semiconductor equipment suppliers, including ASML, are expediting shipments to support the aggressive timeline of Terafab, a joint chip manufacturing venture between Tesla and SpaceX. The announcement, made during a live broadcast of SpaceX’s Q3 2026 earnings call on October 20, highlights the urgency surrounding the project’s goal to begin volume chip production at its primary facility in Gibbons Creek, Texas, by the third or fourth quarter of 2028. Musk emphasized that these targets are highly aspirational and carry significant uncertainty, describing them as having "big error bars." He expressed gratitude to ASML and other partners for accelerating equipment deliveries to help achieve this outcome.

The timeline for Terafab’s development has evolved through several key milestones. SpaceX plans to manufacture its first experimental test chip at its research fabrication facility in Austin, Texas, around the second quarter of 2027. The project’s foundation was strengthened in April 2026 when Intel officially joined the venture to co-develop and refactor silicon fabrication technology, providing access to its 14A manufacturing node. This collaboration is central to the facility’s plan to utilize traditional extreme ultraviolet (EUV) lithography systems. According to unofficial sources, the delivery of Terafab’s first EUV tool was originally slated for mid-2027, though it remains unclear if this represents the expedited schedule Musk referenced in his recent remarks.

The scale of the supply chain involvement required for Terafab is substantial, involving a wide array of global manufacturers. Beyond ASML, the sole commercial supplier of the $400 million EUV lithography systems needed for leading-edge production, the project relies on American equipment makers Applied Materials, Lam Research, and KLA Corporation, as well as Japan’s Tokyo Electron. These firms will provide front-end processing, metrology, and process control machinery. Additionally, Tesla and SpaceX are in discussions with approximately ten South Korean equipment makers, including Hanmi Semiconductor for advanced packaging and HPSP for high-pressure hydrogen annealing, alongside suppliers of specialized piping components and process valves.

Terafab is designed as a vertically integrated, multi-billion-dollar facility capable of manufacturing logic, memory, and advanced packaging architectures in a single location. The project aims to produce one terawatt (TW) of AI computing power annually, a capacity that Musk claims would give the facility a commercial value comparable to the GDP of a top-20 global economy, such as Switzerland. The facility is intended to mitigate future shortfalls of cutting-edge AI processors from external foundries like TSMC by supplying chips for Musk’s xAI clusters, self-driving vehicles, Optimus humanoid robots, and SpaceX’s orbital AI data center.

Musk’s announcement also provided context on the broader AI infrastructure landscape. He stated that his AI companies expect to have 2.5 to 3 gigawatts (GW) of computing capacity active by the end of 2026. He expressed high confidence in bringing an incremental 10 GW online in 2027, suggesting a total of 13 GW by year-end. To achieve this, SpaceX and xAI are aggressively 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. For comparison, the restructured 10 GW Project Stargate and Meta’s 5 GW Hyperion are both expected to reach full capacity in the 2030s.

Despite the ambitious scope, experts have questioned the feasibility of Terafab’s one-terawatt ambition. Research firm Gartner estimates that total global AI-optimized data center capacity is roughly 44 GW as of late 2026, which represents only 4.4% of Terafab’s planned annual output. While global AI computing capacity has grown by roughly 3.3x to 3.4x per year since 2022, according to EpochAI, the jump required for Terafab to meet its targets remains significant. The project’s success hinges on the ability of suppliers to overcome tight capacity constraints across the semiconductor supply chain to meet the expedited delivery schedules.

The next phase for Terafab involves the physical integration of these expedited deliveries and the finalization of the manufacturing process. With the first EUV tool potentially arriving in mid-2027, the facility must rapidly scale up its operations to bridge the gap to the 2028 volume production target. The collaboration with Intel and the procurement of specialized equipment from South Korean and American vendors will be critical in ensuring that the 14A node technology is effectively implemented. As the project moves from planning to execution, the focus will shift to how quickly the facility can transition from experimental test chips in Austin to full-scale production in Gibbons Creek.

If the timeline holds, Terafab could significantly alter the global semiconductor landscape by providing a major new source of advanced AI chips. The facility’s ability to produce such high volumes internally could reduce dependence on traditional foundries and provide a dedicated supply chain for Tesla and SpaceX’s various AI and robotics initiatives. However, the "highly aspirational" nature of the 2028 deadline means that any delays in equipment delivery or manufacturing process stabilization could push the volume production date further out. The coming months will be pivotal in determining whether the expedited supplier commitments translate into tangible progress on the ground.
