Taiwan Semiconductor Manufacturing Co. (TSMC) plans to invest an additional $100 billion to expand its manufacturing campus in Arizona, which increases its total projected U.S. investment to $265 billion. This decision is largely driven by a surge in demand for AI technology, evident from TSMC’s record quarterly earnings, which caused the company to adjust its capital spending outlook upward.
The upcoming expansion will introduce multiple cutting-edge semiconductor fabrication plants and advanced packaging facilities, further solidifying Arizona’s position as a key hub for AI chip manufacturing. TSMC’s Chairman and CEO, C.C. Wei, stated that there has been a consistent and positive outlook from their customers, predominantly cloud service providers, reinforcing TSMC’s confidence in the long-term AI trend.
For data center operators, TSMC’s robust earnings indicate that the demand for AI is translating into construction activities within semiconductor manufacturing. The company’s increase in capital spending and its expanded investment in Arizona signal that the supply chain for semiconductors is still gearing up for the next wave of AI infrastructure development.
In terms of finances, TSMC has raised its capital spending forecast for 2026 to between $60 billion and $64 billion, an increase from the previous $52 billion to $56 billion range. They also project a revenue growth of slightly over 40% in U.S. dollars for the year.
Senior analyst William Li from Counterpoint Research noted that TSMC’s increased spending and growth forecast suggest that the expansion cycle for AI is ongoing and driven by lasting demand for advanced manufacturing capabilities.
During the second quarter, high-performance computing (HPC), which incorporates AI accelerators, CPUs, and networking technology, accounted for 66% of TSMC’s revenue. This marks an increase from 61% in the earlier quarter and 60% from the previous year. Overall, TSMC reported a record revenue of NT$1.27 trillion ($40.2 billion), which is a 36% increase year on year, with a net income rise of 77.4% and a gross margin of 67.7%. In contrast, smartphone revenue fell to 22%, highlighting the increasing role AI plays in TSMC’s business model.
Wei emphasized the evolution of AI infrastructure, noting that the rise of agentic AI is revitalizing the demand for CPUs in AI data centers, thus increasing the need for silicon beyond just AI accelerators. He pointed out that TSMC produces chips for various processors, including x86, Arm, and RISC-V, signifying that this trend is advantageous for TSMC regardless of the specific technology employed.
Customer demand continues to focus on TSMC’s advanced manufacturing processes. In its first commercial quarter, TSMC’s 2-nanometer fabrication technology contributed 3% to wafer revenue, while the 3-nanometer and 5-nanometer processes accounted for 30% and 33%, respectively. Furthermore, technologies at 7 nanometers and below represented 77% of TSMC’s total wafer revenue.
Looking ahead, TSMC anticipates that third-quarter demand will again be influenced predominantly by its advanced manufacturing capabilities, particularly the accelerated ramp-up of the 2-nanometer process. The Chief Financial Officer, Wendell Huang, assured that 70% to 80% of this year’s capital budget would be allocated for cutting-edge technologies, with an additional 10% to 20% to support advanced packaging, testing, and other related manufacturing aspects, while emphasizing that no bottlenecks to their expansion plans are expected.
