TSMC Arizona capacity already sold out
TSMC’s Arizona ramp is being presold years in advance—customers have locked capacity even before some lines are operational, signaling desperate demand for advanced nodes and a U.S. foundry hedge. That pre-sold model gives TSMC leverage but raises pressure on yield and ramp execution that could affect Apple’s wafer-forward planning. (newelectronics.co.uk) (pasionmovil.com)
TSMC’s executives said U.S. fab production slots are fully booked through late 2027, a position the company reiterated after a March 2025 investor briefing by CEO C.C. Wei. (tomshardware.com) Apple, NVIDIA, AMD, Broadcom and Qualcomm are named among customers locking U.S. slots as TSMC expands its Arizona cluster, while Apple separately committed multibillion-dollar production to Fab 21 and reportedly secured over 50% of early 2nm output for 2026. (tomshardware.com) Industry reporting shows at least one planned Arizona module was fully booked before breaking ground and customers have been reserving capacity for lines not yet operational, indicating advance slot purchases extend to future fabs. (wccftech.com) Multiple sources quantify the economic trade-off: chips made in Arizona at 4nm/5nm class nodes have been reported 20–30% more expensive than Taiwan output, and trade press also projects wafer-price increases of roughly 5–10% in 2026 with U.S.-fab premiums possibly higher. (gigazine.net) Analysts note that advance bookings plus constrained high-end capacity give TSMC meaningful pricing and allocation leverage—advanced nodes (≤7nm) already accounted for a majority of wafer revenue in TSMC’s disclosures and AI/HPC demand is concentrating premium utilization. (investor.tsmc.com) Because Apple has precommitted large shares of early-node wafers (notably for 2nm) and TSMC has routed early Arizona-produced batches back to Taiwan for advanced packaging, any ramp hiccups or yield shortfalls at U.S. lines could force wafer-forward schedule changes, cross-site shipping, or prioritization decisions that would materially shift Apple’s 2026 supply mix.
