Musk Launches $20bn Terafab Chip Factory for Tesla, SpaceX

Musk said 80% of Terafab's total compute output would go toward orbital applications, backing SpaceX's stated plan to launch up to one million data center satellites into low Earth orbit.

Elon Musk's Terafab is here: What it is, and why it's important for Tesla and SpaceX

But Musk leaned directly into skepticism at the event, challenging doubters by pointing out that Tesla and SpaceX defied critics who predicted electric cars and reusable rockets would not be feasible or economical. Terafab chips would be needed at scale to boost Tesla’s autonomous and robotics projects, as well as for SpaceX, as its orbital data centers are a big piece of its growth prospects — just as the IPO nears.

Giga Texas Terafab Construction Underway: What It Means for Tesla Owners

Announced on March 21, 2026, the Terafab is a joint venture between Tesla, SpaceX, and xAI — and it's being built right on the North Campus of Giga Texas. The ambition is genuinely unprecedented: integrate every stage of semiconductor production ...

What is Terafab Project? Elon Musk Largest AI Chip Manufacturing facility in the World

Capacity: It aims to reach 1 Terawatt of advanced AI chips per year which is roughly 50 times more than current global output. Total Vertical Integration: Terafab brings design, fabrication, packaging, and testing into a single, massive facility. The World’s Largest Fab: The goal is to reach a production capacity of over one terawatt of AI compute annually, far surpassing any existing facility on Earth.

Tesla’s In-House Chip Factory TeraFab May See Capital Expenditure Far Exceeding Expectations | NAI 500

Musk revealed that upon completion, about 80% of the factory’s capacity will be dedicated to space-related applications, with the remaining 20% for terrestrial uses. The project has been described as “one of the largest semiconductor manufacturing operations ever planned by a private company,” which will make Tesla one of the world’s largest semiconductor manufacturers, thereby eliminating reliance on TSMC, Samsung, or any external suppliers, and achieving full-stack control over the AI stack fr

The Terawatt Transition: Inside Musk’s Galactic Terafab Vision

The Terafab project faces several monumental risks: The Physics of Lithography: Building a leading-edge fab (capable of 2nm or below) is arguably the most difficult engineering feat on Earth. TSMC and Samsung have spent decades and hundreds of billions of dollars to master this.

Why Elon Musk is building ‘Terafab’, a mega chip factory to power his AI empire | Technology News - The Indian Express

Terafab will be used to make two types of chips: One that is optimised for edge and inference. These chips could be used in Tesla’s robotaxis and Optimus humanoid robots.
