Taiwanese chipmaker TSMC has pledged an additional $100 billion to expand its US production footprint, intensifying its Arizona build-out as part of a broader commitment to the United States. The investment, announced by chief executive CC Wei, would lift TSMC’s total US expenditure to about $265 billion and is expected to support the construction of four new plants in Arizona, subject to market conditions. The company reported a 77% surge in second-quarter net profits, with quarterly earnings rising to $22 billion from $12.4 billion a year earlier, underscoring strong demand for its advanced chips used in AI data centres and consumer electronics. Despite the expansion, TSMC’s stock has climbed more than 55% this year, valuing the company at around $2 trillion. Wei emphasized that the timing of new plants will depend on market dynamics, and the eight existing or planned facilities in the state will be complemented by the new capacity. The investment mirrors a broader push by the US to reshore semiconductor manufacturing, an agenda linked to supply-chain resilience highlighted by pandemic-era shortages. The January agreement to reduce Taiwan-origin tariffs to 15% in exchange for substantial investments in domestic chip production is cited as part of the broader framework. Commerce Secretary Howard Lutnick welcomed the plan, noting that President Trump’s leadership is guiding companies to invest in American manufacturing and that the initiative will create tens of thousands of American jobs while strengthening the national semiconductor ecosystem.
TSMC’s ambition to expand in the US aligns with the company’s role as a producer of leading-edge chips used by firms like Nvidia and Apple, supporting the region’s status as a hub for advanced manufacturing. The market response has helped propel the stock toward a multi-trillion-dollar valuation, reflecting investor confidence in long-term US chip production plans and the wider AI-driven demand cycle driving memory and logic chip sales.
The timing follows a period of political emphasis on domestic semiconductor supply chains, with officials underscoring the strategic importance of maintaining US leadership in chip technology and the potential job creation from large-scale manufacturing projects. The Tibble-on plan for new plants remains contingent on market conditions, with the company indicating that further updates will be provided as projects advance.
