TSMC said it will spend another $100 billion to expand U.S. manufacturing capacity.
Why it matters: The new pledge deepens a major semiconductor buildout tied to AI hardware, supply-chain resilience and U.S.-China tech competition. It also raises the stakes for Arizona, where TSMC is already building and running fabs.
- TSMC said July 16, 2026, that the new $100 billion pledge lifts planned U.S. investment to $265 billion.
- The company had already raised its U.S. plan by $100 billion on March 4, 2025, to $165 billion.
- TSMC's 2026 shareholder materials say its first Arizona fab was in high-volume production in Q4 2024.
- The second Arizona fab is expected to start high-volume manufacturing in the second half of 2027, while construction of a third fab began in 2025.
TSMC is making another giant bet on U.S. manufacturing. On July 16, 2026, the chipmaker said it will spend another $100 billion to expand capacity in the United States, bringing its planned U.S. investment to $265 billion, according to AP.
The latest pledge builds on an earlier expansion announced March 4, 2025, when TSMC said it would add $100 billion to its U.S. plan, lifting the total to $165 billion and adding three fabs, two advanced packaging facilities and an R&D center, per the company's announcement here.
TSMC's 2026 annual-shareholder materials show the Arizona project is already partly online. The company's first fab began high-volume production in Q4 2024, the second is expected to begin high-volume manufacturing in the second half of 2027, and construction of a third fab started in 2025, according to its filing.
The move also fits a broader policy backdrop. In January 2026, the U.S. Commerce Department said Taiwanese semiconductor and technology enterprises would make new direct investments totaling at least $250 billion in the United States under an agreement on trade and investment with Taiwan, according to the department.
TSMC's latest annual report shows why the company's scale matters: it posted US$122.42 billion in consolidated revenue and US$55.21 billion in net income in 2025, according to the report.
By the numbers
- $265 billion - TSMC's planned U.S. investment after the latest pledge
- $165 billion - TSMC's prior U.S. plan after its March 2025 expansion
- US$122.42 billion - TSMC's 2025 consolidated revenue
Yes, but: The dossier does not verify how TSMC will allocate the new $100 billion across fabs, packaging or R&D.
What's next: TSMC says its second Arizona fab is expected to begin high-volume manufacturing in the second half of 2027.
