Taiwan chipmaker TSMC to invest another $100bn in Arizona fabs

Taiwan’s TSMC said it will invest an additional $100 billion in Arizona fabs, extending its expansion as record earnings are driven by massive AI chip demand. The company’s chairman, C.C. Wei, said the “AI megatrend” is increasing the need for computation, and TSMC now expects full-year 2026 revenue growth to be slightly above 40% year-on-year in US dollar terms. For April to June, TSMC’s net profit surged 77.4% to NT$706.6 billion (US$22 billion), exceeding analyst estimates, while quarterly revenue rose 36% to NT$1.3 trillion. TSMC plans to spend the extra $100 billion on “four or more” fabs in Arizona and invest across 2-nanometer-and-below logic and advanced packaging. Capital expenditure for 2026 is expected to rise to $60–$64 billion. Analysts noted EUV supply constraints and overseas capacity limits could affect margins.
