Terafab is a planned semiconductor fabrication plant jointly developed by Tesla, SpaceX, and Intel. The venture was announced by Elon Musk on March 21, 2026 and centers on the construction of a vertically integrated large-scale facility designed to produce more than one terawatt of artificial intelligence (AI) compute capacity per year. It aims to produce integrated circuits, memory modules and multi-chip modules under one roof by consolidating every stage of the semiconductor device production process, including chip design, fabrication, memory production, advanced packaging, and testing.
