TSMC Hints at Potential Further U.S. Expansion; Industry Sources Reportedly See Up to US$250B Investment

　　As TSMC continues expanding its U.S. footprint, comments from Cliff Hou, TSMC Senior Vice President and Deputy Co-COO, have caught industry attention. According to Commercial Times, Hou said at the 2026 SelectUSA Investment Summit that the company “is prepared for growth from any new business opportunities,” remarks the market has interpreted as signaling potential further expansion of TSMC’s U.S. investments. TSMC’s total U.S. investment currently stands at US$165 billion.

　　Commercial Times notes that supply chain developments show chip equipment suppliers have also begun establishing U.S. subsidiaries to support TSMC. Industry sources added that TSMC’s total U.S. investment could reach as much as US$250 billion, with the company expected to replicate the Hsinchu Science Park cluster model in Phoenix.

　　Meanwhile, Economic Daily News reported that TSMC’s first Arizona fab entered mass production in 4Q24, while its second fab has already been completed and is expected to begin 3nm mass production in the second half of 2027. TSMC previously said construction of its third Arizona fab is already underway, while permits are being sought for a fourth fab and its first advanced packaging facility in the state. The report also noted that TSMC has acquired a second large parcel of land near its existing Arizona site to support future expansion plans.

　　Although TSMC’s U.S. fabs are more costly, capacity remains in strong demand, with previous reports indicating that customers had already reserved capacity at all four Arizona fabs, as noted by Economic Daily News. Institutional investors said that, for process technologies below 2nm, TSMC’s related capacity ratio between Taiwan and the U.S. is expected to reach roughly 7:3 by 2030.

　　TSMC Reshapes Board Amid Global Expansion

　　In addition, TSMC has also recently adjusted its board structure. According to Commercial Times, the company plans to revise its corporate charter by increasing the number of board seats from the current seven to ten directors to nine to twelve, with the proposal set to be discussed at the shareholders’ meeting on June 4.

　　The move reflects TSMC’s response to the rapidly changing global business environment and is intended to provide greater flexibility in recruiting directors from diverse professional backgrounds, the report said. It also noted that, as TSMC rapidly expands overseas and continues increasing its U.S. investments, the board will need more members with expertise in international supply chains, geopolitics, and U.S. policy.
