TSMC adds $100B more to Arizona plants after strong Q2

TSMC announced an additional $100 billion investment in its Arizona operations on top of prior commitments, after posting $40.2 billion in Q2 2026 revenue. CEO C.C. Wei said roughly four more fabs are planned for the state.

Why it matters: This deepens the shift of advanced chip manufacturing toward the US amid years of onshoring pressure, and signals TSMC's confidence that AI-chip demand justifies the capex even as China pushes for chip self-sufficiency (see CXMT and DeepSeek chip efforts).
