Elon Musk confirms discussions with TSMC about Terafab chipmaking collaboration

TSMC and Elon Musk's Terafab semiconductor production initiative are discussing a potential collaboration under which TSMC would build and operate a facility that will exclusively serve Elon Musk's Tesla, SpaceX, and xAI companies, according to Tim Culpan’s Culpium newsletter on Friday. Elon Musk confirmed the discussions early on Saturday, but did not elaborate.

"Just discussions, but something may come of it," Musk wrote in an X post, while TSMC has so far remained tight-lipped.

Under the arrangement Culpan considers most probable, TSMC would own and operate the new semiconductor production facility, while SpaceX/Terafab could invest in the venture, commit to buying a guaranteed volume of chips, or combine both approaches. However, the exact ownership structure remains under discussion. Another option would put SpaceX in control of the venture with the majority ownership; TSMC would invest less, but would still provide 'operational expertise' and process technologies. …
