Tesla and SpaceX have announced the launch of ‘Terafab,’ a $25 billion chip fabrication facility in Austin, Texas. The facility, which will produce 1 terawatt of computing power annually, is set to be the largest semiconductor fab ever built.
Terafab is a joint venture between Tesla, SpaceX, and xAI, an AI company recently acquired by SpaceX. The facility, located at the North Campus of Giga Texas, will consolidate every stage of semiconductor production, including chip design, lithography, fabrication, memory production, advanced packaging, and testing. Tesla is targeting 2-nanometer process technology for the facility, the most advanced node currently entering commercial production.
The production targets for Terafab are staggering. The facility is designed for an initial output of 100,000 wafer starts per month, with ambitions to scale to 1 million wafer starts per month at full capacity. This full-scale target would represent roughly 70% of TSMC’s entire current global output from a single facility operated by companies that have never fabricated a chip.
Terafab will produce two categories of chips: inference chips for Tesla vehicles and Optimus robots, and D3 chips custom-designed for orbital AI satellites. The facility is expected to produce between 100 and 200 billion custom AI and memory chips per year, powering Tesla’s Full Self-Driving software, Cybercab robotaxi program, and Optimus humanoid robot line.
Elon Musk, Tesla’s CEO, said 80% of Terafab’s compute output would be directed toward space-based orbital AI satellites, with only 20% for ground-based applications. Musk argued that solar irradiance in space is roughly 5x greater than at Earth’s surface, and that heat rejection in vacuum makes thermal scaling viable. His conclusion: orbital AI compute could become cheaper than terrestrial alternatives within 2-3 years.
Company Context
Tesla, founded by Elon Musk, is an American electric vehicle and clean energy company that designs, manufactures, and sells electric cars, solar energy generation systems, and energy storage products. SpaceX, also founded by Musk, is an aerospace manufacturer and space transportation company that designs, manufactures, and launches advanced rockets and spacecraft.
Industry Context
The Terafab chip factory announcement is significant for the semiconductor industry, as it represents a major expansion in chip production capacity. The facility’s ambitious production targets and advanced 2-nanometer process technology could have a significant impact on the global semiconductor supply chain and the development of advanced AI and robotics technologies.
