[News] TSMC Reportedly Eyes 2H27 3nm Mass Production at Arizona Fab 2; Four U.S. Fabs Said to Be Fully Booked

What happened

TSMC is accelerating its Arizona fab construction, with Fab 21 P2 targeting 3nm mass production in 2H27. U.S. fab build timelines have shortened from ~3 years to 1.5-2 years, and capacity at four planned Arizona fabs is reportedly fully booked by major U.S. customers. Neutral: This confirms long-term supply diversification but does not alter near-term supply-demand dynamics for traders.
