A fresh comparison of the semiconductor supply chain's two heavyweights concludes that Taiwan Semiconductor Manufacturing's widening foundry lead and $100 billion Arizona build-out make it the stronger artificial intelligence play, even as ASML's lithography monopoly keeps printing record orders.
The numbers behind the lead
TSMC's share of the global foundry market reached 73 percent in the most recent quarter, up from 69 percent at the end of 2024, while its 3-nanometer and 5-nanometer nodes generated more than 60 percent of revenue. Second-quarter sales climbed 33.7 percent year on year to $40.2 billion, and the net profit margin held at 55.6 percent. Over the past five years net income has risen 251 percent and revenue 165 percent, outpacing the Nasdaq Composite by a wide margin.
ASML's machine count tells its own story
ASML shipped 86 new lithography systems and five used units in the second quarter, up from 67 new and 12 used machines a year earlier. Revenue rose 11 percent to €9.32 billion, or $10.69 billion, and net income increased 5.8 percent to €2.91 billion, with gross margins at 54 percent. Five-year gains in both revenue and net income exceed 90 percent, also beating the broader tech index.
The Arizona factor
TSMC's newly announced $100 billion expansion in Arizona is slated to support advanced packaging and the company's 2-nanometer process, which recorded its first revenue in the latest quarter. Chief executive Christophe Fouquet at ASML said AI-related investments are driving demand for advanced logic and memory chips and giving the Dutch firm visibility into longer-term capacity commitments.
Why the comparison leans toward the foundry
The analysis argues that TSMC's increasing leadership in manufacturing, its technology roadmap, and the scale of its U.S. footprint give it an edge, though it acknowledges there is no bad choice between the two monopolists.
