The Terafab chip factory announced March 21 is designed to produce custom D3 radiation-hardened processors specifically for these orbital satellites — with 80% of Terafab’s production allocated to space applications.
At the heart of TERAFAB is a clear allocation of output: approximately 80% for space based orbital AI data centers and 20% for terrestrial applications. Musk explained that Earth’s power grid (U.S. electricity generation is only about 0.5 TW) simply cannot support the required scale on the ground.
About 20% of the Terafab facility’s annual output will be for “terrestrial” purposes, including chips for Tesla’s Full Self-Driving and Optimus robots, according to the presentation. The remaining capacity will be for space applications, including orbital data centers.
The logic behind it is strikingly simple: Tesla needs chips for autonomous vehicles, for the humanoid robot Optimus, and for AI inference; SpaceX requires radiation-proof space chips for a planned orbital data center infrastructure; and xAI, according to Musk himself, will claim the majority of the total capacity. Since existing suppliers like TSMC and Micron Technology can no longer fully meet the steadily growing demand, Musk sees no other way: "We either build the Terafab or we don'
Elon Musk unveils TERAFAB — a $20-25B Tesla, SpaceX, and xAI joint venture to produce 1+ terawatt of AI compute annually (50x global output). Learn about AI5/AI6/D3 chips, 100M sq ft facility, and 1 million orbital data center modules.
At the TERAFAB launch event in Austin on March 21, Elon Musk made a prediction that would have sounded like science fiction a decade ago...
The terrestrial logistics needed to get this, well, off the ground, are equally mind-blowing. To provide the AI chips for the data centers and other AI ventures, Musk announced a new facility, called “Terafab,” to churn out the uber-advanced processors.
Nvidia CEO Jensen Huang has previously indicated that certain AI processors in its servers are manufactured by Samsung. Meanwhile, Elon Musk has publicly floated the idea of building a “TeraFab” to compete with TSMC.
The project is intended to build advanced chips at very large scale for Tesla, SpaceX, and xAI. Terafab is positioned as a potential competitor to Taiwan Semiconductor Manufacturing (NYSE:TSM) in AI and high end chip supply.
Elon Musk has laid out plans for Terafab, a massive AI chip manufacturing project in Austin intended to support Tesla, SpaceX, and xAI. The project would reportedly involve Intel’s next-generation 14A process and could become a major test of U.S.
Intel (NasdaqGS:INTC) is joining Tesla, SpaceX, and xAI in the Terafab semiconductor initiative in the US. The group plans a pilot chip fabrication facility in Austin focused on advanced manufacturing for AI, robotics, and cloud data infrastructure. This alliance links Intel directly with some ...
Tesla is hiring semiconductor engineers in Taiwan for its Terafab AI chip project, days before reporting first-quarter results on April 22.
Terafab is envisioned as an initiative linked to the needs of Tesla, SpaceX, and xAI, aiming to produce chips for robotics, data centers, autonomous driving systems, and future AI workloads.
The alliance focuses on advanced chip manufacturing for AI, robotics, and space-related computing. The Terafab initiative targets custom, high performance chips aimed at large scale computing capacity.
Terafab will be used to make two types of chips: One that is optimised for edge and inference. These chips could be used in Tesla’s robotaxis and Optimus humanoid robots.

Elon highlights that “increasing ... alternative. The TeraFab facility is designed to address not only chip supply but also the speed at which new compute capacity can be deployed....
It sounds like an ambitious project, though not everyone is buying it. Musk has historically announced wild projects, like the "million-mile" battery that never quite got off the ground. Whether the Terafab facility actually becomes a reality is a waiting game for now.
But Musk leaned directly into skepticism at the event, challenging doubters by pointing out that Tesla and SpaceX defied critics who predicted electric cars and reusable rockets would not be feasible or economical. Terafab chips would be needed at scale to boost Tesla’s autonomous and robotics projects, as well as for SpaceX, as its orbital data centers are a big piece of its growth prospects — just as the IPO nears.
Tesla (NASDAQ:TSLA) appears to be moving deeper into semiconductor manufacturing, with recent job postings pointing to early staffing for its Terafab AI chip complex in Taiwan.
By Wen-Yee Lee TAIPEI, April 17 (Reuters) - Tesla is seeking semiconductor engineers in Taiwan for its Terafab artificial intelligence chip complex, according to job postings on its website.
