Taiwan Semiconductor Manufacturing Co (TSMC) has announced a new $100 billion investment commitment to expand its chip production capacity in the United States.

The pledge, reported by Infomoney on Thursday, signals a significant deepening of the world’s largest contract chipmaker’s footprint in the US market.

The announcement adds to TSMC’s existing manufacturing operations in Arizona, where the company has already committed substantial capital to build advanced fabrication plants.

This latest figure represents a major escalation in the scale of US-based semiconductor manufacturing, reinforcing the strategic shift toward domestic production capacity.

The move comes as global demand for advanced chips remains robust, driven by data-center expansion and artificial intelligence applications.

TSMC’s continued investment in the US aligns with broader industry trends of supply-chain diversification and geopolitical risk mitigation.
