Intel Joins Musk’s Terafab as Foundry Partner in $25B Chip Megaproject
April 8, 2026 – 2:59 pm
In short:
Intel has signed on as the primary foundry partner for Elon Musk’s Terafab, a $25 billion joint venture between Tesla, SpaceX, and xAI targeting one terawatt of AI compute per year. This deal marks a significant milestone for Intel since its strategic shift towards foundries.
On April 7, 2026, Intel announced its partnership with the Terafab project, which aims to establish the most advanced semiconductor facility in the United States. The project, unveiled by Musk two weeks prior, involves building a vertically integrated complex producing between 100 billion and 200 billion custom AI and memory chips annually.
What Terafab Aims to Achieve:
Terafab is designed with the following key components:
- Chip design, lithography, fabrication, memory production
- Advanced packaging and testing
- Two facilities: one for automotive, humanoid robotics (e.g., Tesla’s Full Self-Driving system), and another for high-performance AI data center infrastructure and specialized processors for orbital deployments (SpaceX’s AI Sat Mini constellation).
The project’s ambitious goals include:
- 100,000 wafer starts per month initially, with plans to reach one million at full capacity.
- A total cost estimated between $20 billion and $25 billion by independent analysts, though some question this figure. Bernstein Research suggests a true capital requirement of approximately $5 trillion for one terawatt of annual compute.
Intel’s Role and the Deal’s Value:
Intel will contribute its 18A process node, their most advanced logic manufacturing technology, currently ramping up. This partnership is a game-changer for Intel, securing a marquee customer after a period of struggle.
