Elon Musk announced plans to build a giant chip factory, called Terafab, in Austin, Texas. The factory will produce two types of chips - one optimized for edge and inference to be used in Tesla's autonomous driving and Optimus humanoid robots, and another high-powered chip for SpaceX's space-based data center plans. Musk said the factory will push the limits of physics and computing, though the ambitious project is likely to be incredibly expensive.

Why it matters

Musk's plan to build a massive chip factory in the U.S. is part of his broader vision to turn humanity into a "galactic civilization." The factory will support key initiatives at Tesla and SpaceX, but the scale and complexity of the project raises questions about its feasibility and cost.

The details

Musk announced the Terafab project at an event in Austin, saying it will start as an "advanced technology fab" to produce chips for Tesla's autonomous driving and Optimus robot efforts, as well as high-powered chips for SpaceX's space-based data center plans. Musk said the factory will have all the equipment necessary to make any type of chip, and they will "push the limit of physics and compute." However, building such a massive chip factory is an incredibly complex and expensive undertaking, with estimates suggesting it could cost as much as $300 billion.

• Musk announced the Terafab project on Saturday, March 22, 2026.

What’s next

Musk and his teams will need to secure the necessary funding, acquire the specialized equipment, and navigate the complex process of building a state-of-the-art chip fabrication facility in the U.S. - a task that has proven challenging for even the most experienced chip manufacturers.
