## Key points

- TSMC proposes $265 billion for 12 US chip facilities.
- Most pledged projects lack fixed completion dates.
- Arizona fabs illustrate the long construction timelines.

## Summary

TSMC has announced plans to expand its US semiconductor manufacturing footprint to 12 facilities, with total proposed investment of $265 billion, following an additional $100 billion pledge. The announcement reflects strong demand for AI-related chips and would significantly increase US-based advanced chip production if realised, but the company has not provided firm construction or production schedules.

TSMC has so far spent about $65 billion on two Arizona fab sites and begun work on a third; the first opened in late 2024, while the second is due to start producing 3nm chips in the second half of 2027. Its March 2025 commitment for three further fabs, two advanced-packaging plants and an R&D centre remains unfinished, and it only acquired 900 additional acres for the expansion earlier in 2026. Building and bringing a fab into production typically takes four to five years, leaving delivery dependent on market demand, permitting, infrastructure and economic conditions.
