TSMC Expands U.S. Chip Production With Third Arizona Fab and $100B Investment Boost

Taiwan Semiconductor Manufacturing Co. (NYSE:TSM), the world’s largest contract chipmaker, has officially broken ground on its third semiconductor fabrication plant in Phoenix, Arizona. This marks a major milestone in the company’s aggressive expansion of U.S.-based chip production and investment.

The announcement coincided with a visit from U.S. Commerce Secretary Howard Lutnick, who praised TSMC’s commitment to domestic manufacturing. TSMC Chair and CEO C.C. Wei called the Arizona initiative “the largest single foreign direct investment in U.S. history.” The company plans to pour an additional $100 billion into U.S. operations over the next four years, increasing its total commitment to $165 billion.

TSMC’s expanded investment is expected to create 40,000 construction jobs and tens of thousands of high-paying tech positions in Arizona. According to the U.S. Department of Commerce, this development will contribute over $200 billion in indirect economic output across the state over the next decade.

The move also comes as TSMC looks to mitigate the impact of potential tariffs under President Donald Trump’s trade policies. By localizing production, the chipmaker aims to reduce its exposure to steep import duties on semiconductors and strengthen ties with U.S. customers.

TSMC began manufacturing advanced chips in Arizona in 2024 and plans to operate three fabs in the state. The company plays a critical role in the global tech supply chain, producing chips for leading firms like Apple (NASDAQ:AAPL), Nvidia (NASDAQ:NVDA), and AMD (NASDAQ:AMD).

Apple CEO Tim Cook, Nvidia CEO Jensen Huang, and AMD CEO Lisa Su all praised TSMC’s latest Arizona facility, citing its importance for U.S. innovation and tech resilience. Increased domestic chip production is expected to enhance supply chain security and support American technological leadership.
