GoKawiilElon Musk confirms Terafab talks with TSMC over dedicated chip fab
Elon Musk confirmed on X that discussions are underway with TSMC about a potential collaboration tied to his Terafab chipmaking initiative, saying 'something may come of it.' According to Tim Culpan's Culpium newsletter, the most likely arrangement would have TSMC own and operate a new fab serving only Tesla, SpaceX, and xAI, with SpaceX/Terafab possibly investing or committing to chip purchase volumes; a less likely alternative would give SpaceX majority ownership with TSMC providing operational and process expertise.
GoKawiil's interpretation of the reporting above, not reported fact.
The reported talks suggest TSMC's rumored Texas fab expansion may be linked to supporting Terafab, which could reshape how the foundry structures partnerships beyond its existing Japan and Germany joint ventures. Culpan's analysis raises the possibility that Intel's planned role supplying 14A process technology to Terafab could be displaced if TSMC takes a larger operational stake, though this remains speculative until either company confirms specifics.
- Musk confirmed TSMC-Terafab talks exist but gave no details on structure or timing.
- Culpan outlines two possible ownership models: TSMC-led (similar to JASM/ESMC) or SpaceX-majority with TSMC as operator.
- Intel's planned 14A supply role for Terafab could be jeopardized if TSMC's involvement deepens.
