Tesla's Terafab Project Launches in 7 Days, Elon Musk Announces

Tesla's massive Terafab project for AI chip manufacturing is set to launch in 7 days, announced by Elon Musk. This significant development signals Tesla's ambition in vertical integration for autonomous vehicles and AI chip production.

Elon Musk announced on March 14 that TSLA's ambitious Terafab project will launch on March 21, 2026, at a site adjacent to Giga Texas in Austin. Terafab is Tesla's planned in-house semiconductor fabrication facility — a move that could fundamentally reduce the company's dependence on external chip suppliers like TSMC and accelerate AI hardware development for autonomous vehicles and Optimus robots.

The project carries an estimated cost of approximately $25 billion and is designed to produce between 100 and 200 billion custom AI and memory chips per year, targeting 2-nanometer process technology — the most advanced node currently in commercial production. Tesla aims for an initial output of 100,000 wafer starts per month with ambitions to scale toward one million, which would represent roughly 70% of TSMC's current total output in a single U.S. facility.

Analysts caution that the March 21 'launch' likely refers to a formal project announcement or groundbreaking ceremony rather than an operational fab, as semiconductor facilities of this scale take years to construct and commission. Tesla's fifth-generation AI chip, AI5, is expected to begin small-quantity production in 2026, with volume production projected for 2027.
