Tesla and SpaceX Unveil Terafab Chip Project
The joint Terafab initiative includes a $3 billion research fab in Austin and a planned production site in Grimes County, Texas.
Updated on Nov. 7, 2026 in Semiconductors
Elon Musk announced Terafab on March 21, 2026, a semiconductor project joined by Tesla and SpaceX. Intel joined the effort as a foundry partner on April 7, 2026.
Why it matters
Terafab is aimed at supplying chips for Tesla's vehicles, Optimus humanoid robots, and Cybercabs, as well as AI hardware for SpaceX's planned space-based data centers. The Texas buildout positions the state as a site for advanced chip manufacturing.
The Giga Texas research fab carries an estimated $3 billion cost and is designed for rapid prototyping of new chip designs. The long-term goal is 1 terawatt of annual AI compute capacity, though no completion date for that target has been announced.
The players
Tesla
Tesla is an electric vehicle and energy company led by Elon Musk, and its vehicles and robots are among the primary intended users of Terafab chips.
SpaceX
SpaceX is a private aerospace manufacturer and launch provider led by Elon Musk, which is planning space-based data centers that will require its own AI hardware.
Intel
Intel is a major American semiconductor manufacturer that joined Terafab as a foundry partner, targeting its 14A process node.
The details
The first piece of Terafab is a research fab at Tesla's Giga Texas campus in Austin, where construction began in April 2026. The main production site is planned for Grimes County, Texas, with an initial investment of $16.8 billion and projected to create at least 3,000 jobs.
Timeline
March 21, 2026: Elon Musk announces Terafab.
April 2026: Construction of the Giga Texas research fab begins.
April 7, 2026: Intel joins Terafab as a foundry partner.
The Tech Race
Terafab's Intel partnership targets Intel's 14A process node, placing the project within the competition to advance leading-edge chip manufacturing. Its vertical focus on Tesla and SpaceX hardware distinguishes it from foundries that manufacture chips for many customers.
The Terafab project's chips are intended for Tesla vehicles, Optimus robots, and Cybercabs, so its outcome could affect the features and availability of those products. The Grimes County facility's projected 3,000 jobs would be a direct employment effect for Texas residents if the project proceeds.
The takeaway
Terafab shows large technology companies moving to control more of their own chip supply, from research prototyping through production. Readers following the semiconductor industry may watch whether the planned Texas facilities reach their stated scale and timelines.
