Elon Musk took the stage over the weekend to announce a new partnership between Tesla, SpaceX and xAI to build a $25 billion chip-making factory in Austin, Texas, called Terafab.
Acknowledging Samsung, TSMC and other chipmakers, Musk said the Terafab project needs to get off the ground because existing semiconductor partners aren’t making chips fast enough. If built, Terafab would be the largest semiconductor manufacturing plant in the world.
Bringing more semiconductor facilities to the US isn’t new. The CHIPS Act of 2022 saw a dramatic rise in announcements for further investments in such facilities on American soil. Nvidia began manufacturing chips in its Arizona factory last year, and the motivation wasn’t only due to tariffs.
The CHIPS Act has paid out for several chip-making projects, including Intel’s massive $8 billion factory, though the introduction of additional semiconductor fabs in the US has been slow. Terafab would be a significant addition to the infrastructure for onshore chip making in the US, and by far the most expensive. There’s no word yet on whether Terafab would receive funding under the CHIPS Act.
Powering all of your electronic devices are chips that serve as their brains. They vary from the likes of Apple’s M series to Nvidia’s Vera Rubin CPU and beyond. The Terafab project aims to ease the current shortage of chips powering devices that will bring AI robotics and more to life. (The AI boom has also brought about a massive RAM shortage, with no expected relief until 2028, affecting prices on electronics like smartphones and laptops.)
Musk gave details on two of the chips he plans to build, the AI5 and AI6, which would power the likes of existing earthly ventures, such as Tesla’s Optimus robots and self-driving cars. Also detailed was the D3 chip, which he said would be made for orbital satellites in space. This type of ambition isn’t just coming from Musk, either. Nvidia announced similar goals to build orbital AI data centers during its GTC conference last week.
The project aims to have every piece of the manufacturing process take place at the facility to churn out chips by the billions, targeting the 2-nanometer process. Musk believes the project will help propel us into becoming a “galactic civilization.”
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.
