TSMC adds $100 billion to Arizona investment amid AI chip demand

Taiwan Semiconductor Manufacturing Co. (TSMC) announced an additional $100 billion investment in its Arizona operations, bringing total planned investment to $265 billion, driven by a multi-year structural surge in AI chip demand. CFO Wendell Huang stated the funds will cover front-end wafer fabrication and back-end advanced packaging facilities. TSMC's first Arizona fab is operational with yields matching its Taiwan facility, with construction ongoing for additional fabs and an R&D center. The company raised its 2026 capital expenditure guidance to $60-64 billion. TSMC reported record second-quarter net income of NT$706.56 billion, a 77.4% increase year-over-year, with high-performance computing (including AI chips) generating 66% of revenue. Despite strong results, TSMC stock fell 7.3% but remains up 48% year-to-date. Huang noted U.S. fabrication costs are 4-5 times higher than in Taiwan but argued the expansion strengthens the U.S. semiconductor supply chain.
