Elon Musk has confirmed that both SpaceX and Tesla will remain key customers of Taiwan Semiconductor Manufacturing Company (TSMC), highlighting the chipmaker’s critical role in powering the future of electric vehicles, AI, and space technology.

Speaking on the growing demand for advanced semiconductors, Musk noted that TSMC currently cannot produce the massive volume of chips required by his companies. He described the demand as “astonishing,” showing just how fast Tesla and SpaceX are scaling their operations.

Musk added that if TSMC were able to fully meet those production needs, there would be no reason to pursue the proposed “Terafab” chip factory project. His comments underline both the importance of TSMC in the global supply chain and the rising need for more semiconductor manufacturing capacity worldwide.

As Tesla expands its autonomous driving systems and SpaceX continues pushing satellite and rocket technology forward, access to high-performance chips remains one of the most important factors for future growth.
