TSMC pledges ~$100B more for Arizona, lifts 2026 capex to $60–64B

On its July 16 earnings call, TSMC said it will invest roughly $100 billion more to expand its Arizona campus - adding at least four more fabs to make 2nm-and-below chips - lifting its total planned U.S. investment to about $265 billion, the largest foreign direct investment in U.S. history. The chipmaker also raised its 2026 capital-spending forecast to a record $60–64 billion, up from a prior $52–56 billion, with 70–80% earmarked for advanced process technology. TSMC said that once the Arizona buildout is complete it expects about 30% of its 2nm-and-below capacity to sit in the United States.
