TSMC Boosts Phoenix Manufacturing Investment by $100B
This brings the total investment to a record $265 billion, with far-reaching impacts on the local economy.
Chip giant Taiwan Semiconductor Manufacturing Co.’s announcement yesterday that it is boosting its investment in Greater Phoenix by an additional $100 billion for a total of $265 billion was hailed as a gamechanger for the semiconductor and advanced manufacturing industries in Arizona and the U.S.
The project is the largest economic development and foreign investment deal in U.S. history.
TSMC Chairman and CEO C.C. Wei said during the company’s quarterly earnings call that the new investment will likely result in four additional advanced semiconductor manufacturing fabs being built at the roughly 1,100-acre campus in Phoenix’s Northwest Valley.

That would bring the total investment at the site to 10 semiconductor manufacturing fabs, two advanced packaging facilities and an R&D center. He said construction of the four new fabs would depend on market conditions but noted that global demand for artificial intelligence infrastructure is fueling the growing demand for chips.
Wei said in prepared remarks the additional $100 billion investment will support strong multi-year demand from its leading U.S. customers. TSMC manufactures chips designed by Nvidia, Apple and other companies. He said it should also foster further development of the U.S. semiconductor ecosystem, strengthen the supply chain and support significant job creation in the U.S.
In reaction to the announcement, U.S. Commerce Secretary Howard Lutnick said the additional investment will create tens of thousands of American jobs and bring advanced semiconductor manufacturing back to the U.S.
TSMC’s growth expands region’s industrial base
Ian Wolfe, senior research analyst at Transwestern, told Commercial Property Executive that the additional investment by TSMC represents another significant milestone in Phoenix’s evolution as a global semiconductor manufacturing hub. He said the long-term impact extends beyond TSMC’s campus, reinforcing Arizona’s ability to attract suppliers, equipment manufacturers and other high-value industrial users seeking to locate within an established semiconductor ecosystem.
“The continued expansion of chip manufacturing, particularly as AI demand grows, should provide durable support for industrial real estate fundamentals by generating new investment, high-paying jobs and incremental demand throughout the advanced manufacturing supply chain,” Wolfe said.
Nik Vallens, senior director and industrial broker at Cushman & Wakefield in Phoenix, agreed, calling the continued investment from TSMC “another strong validation of Arizona as a strategic location for advanced manufacturing.”
Vallens said the real estate impact extends well beyond the fabs themselves.
“We’ve seen a significant uptick in domestic and overseas suppliers and manufacturers targeting Phoenix facilities to support TSMC, Intel and similar projects,” Vallens told CPE. “As reshoring accelerates, Greater Phoenix is well positioned to capture a meaningful share of that long-term industrial growth.”
Growth in the region is already underway. Several months ago, Mack Real Estate Group and McCourt Partners broke ground on Halo Vista, a 2,300-acre, $7 billion master-planned development adjacent to TSMC’s campus. The project calls for 30 million square feet of industrial, manufacturing, office, retail, residential and educational uses.
Amkor Technology, a semiconductor packaging and testing company, is building a $7 billion advanced manufacturing campus about 20 miles away in Peoria, Ariz. The project is slated for completion in 2027.
Tracking TSMC Arizona’s growth
The company made its first investment in Arizona in 2020 to develop a $12 billion manufacturing plant. Two years later, TSMC grew its commitment to $62 billion with plans to build a second fab. In April 2024, the company announced a $65 billion investment under the CHIPS and Science Act to add a third fab. The company also received a $6.6 billion federal grant.
Last year, Wei met with President Donald Trump at the White House to add $100 billion to the TSMC Arizona investment for a total of $165 billion. At that time, it was the largest foreign direct investment in U.S. history—until this week’s announcement.
The first fab has been completed and is operating. Construction of the second fab is complete, with equipment installation happening this year with chip production targeted to begin in late 2027. The company broke ground on the third fab last year.
