Musk Says TSMC Talks for Terafab Chip Project Are 'Just Discussions'

Elon Musk has confirmed that early conversations are taking place with Taiwan Semiconductor Manufacturing Company about a possible role in Terafab, the sprawling semiconductor venture he is building alongside Tesla and SpaceX. Responding to a question on X, Musk kept expectations modest, writing that the talks amount to “just discussions” for now — though he left the door open by adding that something may eventually come of them. No agreement has been signed, and nothing has been ruled out either.

The speculation traces back to semiconductor analyst Tim Culpan, who sketched out how such a partnership might work. Under one scenario, TSMC could treat Terafab as an anchor customer for future fabrication plants in Texas, bringing process technology, operational expertise or manufacturing capacity to the table. In return, Terafab would contribute capital, long-term purchasing commitments, or a combination of both. That structure would give the Taiwanese foundry a guaranteed buyer before committing to new U.S. capacity, while handing Terafab access to the industry’s most advanced production know-how.

Terafab itself is a joint effort between Tesla and SpaceX. Musk unveiled the initiative in March, describing a facility intended to churn out more than a terawatt of AI compute capacity every year once it reaches full scale. Intel signed on in April 2026 and is expected to supply its 14A process for the completed plant. The first phase carries an estimated price tag of roughly $16.8 billion, with later filings suggesting the total could climb into the tens of billions as additional stages come online.

The rationale behind the project is straightforward: Musk has argued that demand from Optimus humanoid robots, Cybercab vehicles and planned orbital data centers will eventually outstrip what the global chip industry can supply. Tesla already sources AI5 and AI6 processors from Samsung, and Musk has said existing partners including Samsung and TSMC remain essential for near-term needs. Terafab is framed as the long-term fix for a projected shortfall, echoing the stopgap measures Tesla took during the COVID-era chip crunch — only at a far larger scale.

For now, the only public confirmation is Musk’s brief acknowledgment that conversations are happening. If a deal with TSMC were to materialize, it would layer the foundry giant’s manufacturing leadership on top of a project that already combines Tesla and SpaceX capital and offtake with Intel’s process technology — a combination that would rank among the most significant advanced-chip collaborations currently under discussion in the United States.
