Tesla Terafab Austin: Vendor Opportunities at the $20 Billion Chip Fab Joint Venture
Tesla Terafab announced March 2026 as a Tesla/SpaceX/xAI joint venture on 2,500 acres in Austin. Intel 14A process technology, $3B pilot fab, and the widest vendor…
On March 21, 2026, Elon Musk announced the Terafab project: a joint venture between Tesla, SpaceX, and xAI to build advanced semiconductor manufacturing capacity at the Gigafactory Texas campus in Austin. Intel joined the project on April 7, 2026, providing 14A process technology, Intel's most advanced node at sub 2nm class. The pilot research fab covers 2 million square feet of the over 5.2 million square feet of new building space permitted at the Giga Texas North Campus. Investment: $3 billion for the pilot fab, $20 to $25 billion for the broader Tesla/SpaceX initiative. SpaceX has estimated total phases at $55 billion initial and $119 billion total.
For vendors selling ultrapure water systems, specialty gases, vacuum equipment, abatement, metrology, cleanroom construction, or process chemicals, Terafab represents the widest vendor qualification window of any active Texas chip fab project. The facility is in its earliest construction phase. No public approved vendor list exists. The AVL is being built now, not defended. This is the phase where vendor decisions get made.
