Future TechnologyIntel and Musk's Terafab Is Now a $119 Billion Bet on Texas
Key takeaways
- Terafab, the Tesla, SpaceX and Intel chip factory, could cost up to 119 billion dollars across all phases
- The full-scale plant in Grimes County, Texas aims for a million wafer starts a month and up to 200 billion chips a year
- Musk says the site will run Intel's 14A process, a major vote of confidence in Intel's comeback
- If it works, it pulls advanced chipmaking away from Taiwan and onto American soil
Terafab, the chip factory backed by Tesla, SpaceX and Intel, keeps getting bigger. A May 2026 filing put the full Terafab chip factory build at up to 119 billion dollars, with 55 billion earmarked just for the first prototype phase. The plan is a vertically integrated plant in Grimes County, Texas, aiming for a staggering million wafer starts a month.
Why Intel is the quiet winner
Elon Musk announced Terafab in March, and the eye catching numbers are the scale: up to 200 billion custom AI and memory chips a year, feeding Tesla robots, SpaceX satellites and whatever comes next. But the detail worth pausing on is who makes them. Musk said the full-scale site will run Intel's 14A process, its 1.4 nanometre node. For a company plenty of people had written off, that is a serious vote of confidence, and it plants Intel right at the centre of one of the most ambitious factories ever proposed.
What it means for the chip supply chain
The world's most advanced chips are made almost entirely in Taiwan, a concentration that quietly worries governments and boardrooms alike. Terafab is a bet on changing that, pulling leading edge manufacturing onto American soil. It fits a broader scramble for chip capacity, the same one behind our piece on Samsung's 648 billion dollar chip bet and Nvidia's move into PC processors. Even companies like DeepSeek are designing their own silicon to control their supply.
There are real catches. Grimes County commissioners approved a full tax abatement in June to land the project, and building a fab this size takes years, not months. Musk timelines are famously optimistic. But if even part of Terafab comes good, a chunk of the world's chipmaking future moves to Texas, and Intel gets the comeback story it has been chasing for a decade.
