TSMC Preparing $100 Billion Package to Add Four More Fabs to Arizona Facility

TSMC is reportedly planning to announce the addition of four new fabs at its Phoenix, Arizona site, known as TSMC Arizona. According to the Financial Times, TSMC will add four additional fab buildings at its Arizona campus, worth about $100 billion, with an official confirmation expected as early as April, just two months from the time of writing. In January, TSMC reportedly purchased additional 900-acres of land directly across the highway from the existing site north of Phoenix, preparing to expand its campus across. That extra production capacity will be supported by an estimated $100 billion of additional funding that TSMC is willing to spend on U.S. soil, despite making additional simultaneous investments back home in Taiwan.
However, many of the deal's specifics are still uncertain. According to Commerce Secretary Howard Lutnick, about $100 billion of those pledges are firm, which means that the total value of TSMC's investment in Arizona will amount to $265 billion. About $165 billion has already been invested in Arizona, and another $100 billion will make this one of the highest ever external investments on U.S. soil. Interestingly, TSMC is not alone in this investment round, as its supply chain partners are expected to contribute about $30 billion of the $100 billion figure, meaning that many more players are gathering funds to form the new supply chain independence.
