Tesla chief executive Elon Musk has announced that the company’s ambitious Terafab project, a gigantic in-house semiconductor manufacturing facility, will be officially launched in seven days.
In a post on X on Saturday, Musk simply stated: “Terafab Project launches in 7 days.” The announcement marks a significant milestone for Tesla as it seeks to take full control of the production of advanced artificial intelligence chips.

The Terafab, shorthand for “tera-scale fabrication plant,” is designed to be far larger than Tesla’s existing Gigafactories. It will integrate logic chip production, memory fabrication and advanced packaging within a single massive domestic facility in the United States. Musk has previously said the plant is essential to meet projected demand for hundreds of billions of custom AI chips per year, powering everything from Full Self-Driving software and Robotaxi fleets to Optimus humanoid robots and the Dojo supercomputer cluster.
The project addresses what Elon Musk described as a looming supply bottleneck. Tesla currently relies on external foundries such as TSMC and Samsung, but he has cited “geopolitical risks” and the sheer scale required for Tesla’s AI ambitions as reasons for building its own capacity.
Elon Musk first outlined the vision publicly at Tesla’s 2025 annual shareholder meeting, declaring: “So I think we may have to do a Tesla Terafab. It’s like Giga but way bigger. I can’t see any other way to get to the volume of chips that we are looking for.” He reiterated the need during the company’s January 2026 earnings call, adding that a “bigger announcement” on the project would follow later in the year.
Terafab is a major step in Tesla’s vertical integration strategy, moving the electric-vehicle maker deeper into the semiconductor sector. Construction is expected to begin immediately upon launch, with the facility ultimately targeting output on a scale comparable to or exceeding leading global chipmakers.
Tesla shares rose in after-hours trading following the announcement, reflecting investor optimism about the company’s push to secure its AI hardware future independently.
