TSMC Invests $100B in Arizona Amid AI Demand & US-China Tensions

Taiwan Semiconductor Manufacturing Co (TSMC) will invest an additional US$100 billion in Arizona to expand chip production capacity, responding to strong demand from US customers driven by the artificial intelligence boom. The company is already the largest foreign investor in the US with a total commitment of US$265 billion as part of a trade agreement between Washington and Taipei. TSMC aims to establish a total of ten chip fabrication plants and two packaging facilities in Arizona by the end of the decade.

This expansion addresses growing concerns in Washington about the concentration of advanced semiconductor manufacturing in Taiwan, which faces geopolitical risks. While TSMC prioritizes deploying new technologies in Taiwan first due to the need for close R&D collaboration, the Arizona investment seeks to secure supply chains and serve key AI clients like Nvidia and Apple. Analysts have expressed concerns about TSMC’s margins and a recent selloff in tech stocks amid questions about the profitability of heavy AI spending.
