Key Takeaways: TSMC committed an additional $100 billion to its Arizona operations, bringing total US investment to $265 billion. The company reported Q2 net income of $21.9 billion, up 77.4 percent year over year, and raised its 2026 capex to as much as $64 billion. About 30 percent of TSMC's global 2nm and below capacity will be in Arizona once all 10 fabs are complete.
Taiwan Semiconductor Manufacturing Co. raised its total US investment to $265 billion with a new $100 billion commitment to Arizona, betting the AI infrastructure build-out will sustain demand for its most advanced chips through the end of the decade.
The additional spending, announced July 16 during TSMC's second-quarter earnings call, will add four fabrication plants using 2-nanometer and below technologies to the eight facilities already planned or under construction in north Phoenix. The expansion brings TSMC's Arizona campus to 10 fabs, two advanced-packaging facilities, and a research and development center.
"This investment will help to further foster the development of the US semiconductor ecosystem, strengthen the supply chain, and support an increasing number of high-tech, high-paying jobs in the United States," Chairman and Chief Executive Officer C.C. Wei said.
TSMC reported second-quarter revenue of $40.2 billion, up 33.7 percent from a year earlier, and net income of $21.9 billion, a 77.4 percent jump. The company raised its 2026 capital expenditure budget to between $60 billion and $64 billion, up from a prior range of $52 billion to $56 billion, and now expects full-year revenue growth slightly above 40 percent.
The investment signals that the world's largest contract chipmaker sees no let-up in demand from customers such as Apple, Nvidia, AMD, Broadcom and Qualcomm. High-performance computing — the category that includes AI accelerators and data center processors — accounted for 66 percent of TSMC's second-quarter revenue, while smartphones contributed 22 percent. Wei described AI-related demand as "extremely robust" and said he expects strong demand through 2029 and 2030.
Arizona campus becomes a global manufacturing anchor
TSMC's first Arizona fab began high-volume production using N4 technology in the fourth quarter of 2024, with yields matching those of the company's Taiwan facilities. The second fab, using N3 technology, is scheduled to begin volume production in the second half of 2027. Construction of the third fab, planned for N2 and A16 technologies, started in April 2025, with production targeted before the end of the decade.
Once all announced fabs are complete, about 30 percent of TSMC's worldwide capacity for 2-nanometer and more advanced technologies will be located in Arizona. The company's 2-nanometer process, which packs more transistors per square millimeter to improve performance per watt, contributed 3 percent of wafer revenue in the second quarter as early production ramps. The 3-nanometer node generated 30 percent and 5-nanometer accounted for 33 percent.
The expansion is rippling beyond TSMC's campus. Amkor Technology is investing $7 billion in a 750,000-square-foot packaging plant along Loop 303 in Peoria, expected to create 3,000 jobs with an average salary of $90,000 annually. The city of Peoria has taken the lead on planning 6,700 acres of state trust land — dubbed the Peoria Innovation Core — to attract suppliers and manufacturers along the semiconductor supply chain.
What the investment means for investors
TSMC's $60 billion to $64 billion capital expenditure plan for 2026 signals management's conviction that the AI chip cycle has years of runway. The company's gross margin reached 67.7 percent in the second quarter, up 1.5 percentage points from the first quarter, though Wei cautioned that the rapid ramp of 2-nanometer production would reduce gross margin by about 3 to 4 percentage points in the second half of the year.
For the third quarter, TSMC guided revenue between $44.6 billion and $45.8 billion, with gross margin between 65 percent and 67 percent. The company's shares have gained more than 55 percent year to date, giving it a market capitalization of roughly $2 trillion. The stock has pulled back in recent weeks amid broader semiconductor sector weakness, but the scale of this capex commitment suggests management sees the current dip as a buying opportunity for capacity.
The $265 billion Arizona build-out also carries implications for TSMC's competitors and customers. Intel, which has struggled to establish its foundry business, faces a rival with a committed US manufacturing footprint and a proven technology roadmap. Nvidia, Apple and AMD gain supply chain redundancy outside Taiwan, reducing geopolitical concentration risk. The US Commerce Department said the project "will create tens of thousands of American jobs and bring advanced semiconductor manufacturing back to America."
