Add us on Google by Editorial Team Jun. 4, 2026TSMC has enough room in Arizona to keep building for the next ten years. That’s the word from Chairman and CEO Dr. C.C. Wei, who confirmed during a recent earnings call that the company’s two land parcels in north Phoenix, totaling more than 2,000 acres, will accommodate its expansion plans through the mid-2030s.
The Arizona footprint takes shape
TSMC’s Arizona story has two chapters, measured in dirt. The original site covers roughly 1,100 acres, where the company’s first American fab has been running high-volume production since late 2024 with more than 3,000 employees on site.

Wei’s confirmation that these combined parcels will suffice for a decade suggests the company has already mapped out a multi-phase buildout. The vision is what TSMC calls a “gigafab cluster,” a sprawling complex that would include multiple advanced fabrication plants, packaging facilities, and a dedicated R&D center.
Construction on the second fab is set for completion with tool installation planned for later in 2026. High-volume manufacturing at that facility is targeted for late 2027.
The total US investment commitment has ballooned to $165 billion, which TSMC says makes it the largest foreign direct investment in US history. The projected indirect economic benefit exceeds $200 billion.
Why AI is driving the land grab
Wei pointed to strong, multi-year demand fueled by AI technologies embedded in smartphones and computing systems as the primary driver behind the company’s growth trajectory.
