TSMC Discusses Potential Role in Elon Musk’s Texas Terafab Chip Venture
By Drooid · · How we work
Core Event
Elon Musk’s semiconductor initiative, Terafab, is in preliminary talks with Taiwan Semiconductor Manufacturing Co. (TSMC) about a partnership to help operate a new wafer-fab in Grimes County, Texas. The discussions were confirmed by Musk on October 3, when he posted on X that the talks are “just discussions, but something may come of it.” No formal agreement, ownership structure, or timeline has been disclosed.
Background & Context
- Terafab announcement – Musk unveiled the project on March 21 2026, describing a goal of delivering a full terawatt of AI compute capacity per year, a level he said would exceed the combined output of all existing chipmakers.
- Site and investment – Tesla and SpaceX identified a site in Grimes County, Texas, with a first-phase investment of $16.8 billion and a projected workforce of at least 3,000 employees (confirmed August 6). The overall build-out could reach up to $119 billion across multiple phases.
- Technology plan – Terafab aims to integrate design, lithography, fabrication, memory, advanced packaging, and testing under one roof, targeting a 2-nanometer process node for AI chips used in autonomous vehicles, humanoid robots, and high-heat space applications.
- Intel involvement – Intel joined the venture in April 2026, supplying its 1.4 nm-class 14A process technology for the initial production run.

Official Statements & Responses
- Elon Musk (X post, October 3) – Confirmed that talks with TSMC are ongoing but stopped short of announcing a deal.
- Intel – Has committed to supply its 14A process technology to Terafab, positioning the company as the current technology source pending any change resulting from a TSMC partnership.
Conflicting Reports & Gaps
- All sources agree that discussions are exploratory; none report a signed contract, specific financial terms, or a definitive timeline for TSMC’s involvement.
- Speculative ownership models (e.g., TSMC-owned “Plan A” vs. SpaceX-majority “Plan B”) appear in analysis pieces but are not confirmed by either party.
- The extent to which TSMC’s patents might intersect with Intel’s 14A node remains unaddressed, leaving potential intellectual-property concerns unresolved.
