C. Wei, Chairman and CEO of TSMC, has been actively addressing the company's capacity expansion and AI-driven demand in recent earnings calls. In the Q2 2026 call, he announced an additional $100 billion investment in Arizona to build fabs for 2-nanometer and advanced packaging technologies, citing strong multi-year demand from US customers. He stated that the AI mega trend continues to drive robust demand for leading-edge silicon, and that TSMC's conviction in the multi-year AI outlook remains very high. In earlier calls, Wei noted that TSMC's wafer supply, not power consumption, is currently the bottleneck for AI infrastructure, and that he has spent significant time speaking directly with cloud service providers to validate demand before committing to large capital expenditures. Wei has also addressed geopolitical and market uncertainties. In the Q2 2025 call, he said TSMC had not seen changes in customer behavior due to tariff policies but acknowledged risks to consumer-related segments. He reaffirmed that TSMC is not engaged in discussions regarding joint ventures or technology licensing with other companies. Regarding overseas expansion, Wei stated that TSMC is executing its plans in Japan and Europe as scheduled, and that these investments in specialty technology are not competing with leading-edge expansion in the US. He described the current environment as one of "fragmented globalization," where overseas fab costs are higher for all manufacturers, but TSMC aims to remain cost-effective through manufacturing scale and technology leadership.
