Musk: Location of TeraFab Chip Plant for Tesla Optimus Robots to Be Announced Soon

In July 2026, Elon Musk said Tesla will soon announce the site for TeraFab, its own chip plant, which the company calls critical for scaling production of the Optimus humanoid robot.

What we know about TeraFab

TeraFab is a planned Tesla facility for mass production of semiconductors, and according to Musk, Optimus output cannot be scaled up without it. Tesla has not yet named a specific site, but promises to do so soon.

• The location of TeraFab will be announced "very soon," according to Elon Musk (as reported by 财联社, Cailian Press)
• Equipment for a development (pilot) fab in Austin has already been ordered
• The plant's purpose is to produce chips for the Optimus humanoid robot
• The name TeraFab itself points to "tera"-scale production

According to 财联社, the company has already ordered equipment for the development fab in Austin, the city that is home to Tesla's headquarters and Gigafactory Texas. This is a separate pilot line, not the future TeraFab itself, whose location has yet to be revealed. Tesla announced the Optimus program in 2021 and showed its first working prototypes in 2022.

Why Tesla needs its own chip plant

Tesla needs its own plant to supply Optimus robots with compute chips without waiting in line for capacity at contract manufacturers. Musk has repeatedly said that access to advanced semiconductors is a bottleneck for any plan to mass-produce devices.

The logic of the project is vertical integration: its own silicon for its own products. According to Musk's earlier public statements, Tesla expects to eventually build millions of Optimus robots a year, and at that scale outside chip supply may simply not be enough. Hence the bet on in-house production at "tera" volumes.

Global leading-edge manufacturing capacity, held by TSMC and Samsung, is currently overloaded with orders for AI accelerators, and the queue for it is long. Tesla already designs its own chips: the autopilot computer (the FSD computer) and the Dojo system for training neural networks. TeraFab continues that line but shifts the emphasis from design to mass production of silicon.

What TeraFab would mean for Optimus production

TeraFab is meant to remove the main physical constraint on mass-market Optimus: the number of chips available for the robot's "brain." Each robot needs a powerful processor to handle vision and motion control in real time, and when robots ship by the million, the total demand for silicon becomes enormous.

For now, this is an early stage: equipment has been ordered only for the pilot fab in Austin, and the site for a full-scale TeraFab has not yet been publicly chosen. Tesla has not disclosed actual volumes, launch dates or the type of chips.

TeraFab will be announced very soon, and the facility itself is critical for ramping up Optimus production.

What this means

Tesla is signaling that chip production is the main barrier to mass-producing robots, and that it is ready to build a dedicated plant to overcome it. If TeraFab is actually launched, it would be a step toward full vertical integration of Tesla's robotics, from chip to finished Optimus. The move fits a broader trend: big tech companies increasingly build or commission their own silicon to avoid depending on the market. For now, though, this is only an announcement of intent. With no address, budget or timeline, there are few specifics, and the project's viability can be judged only after the location is officially announced.
