TSMC is reportedly evaluating locations for a second U.S. chipmaking hub, according to a MarketWatch report, a move that would extend the world's largest contract chipmaker's American manufacturing footprint beyond its existing Arizona complex.

The report did not name a specific city or state that TSMC has settled on, describing the search as still in the exploratory "eyeing" stage. That qualification matters. A site under evaluation is not a committed fab, and TSMC has historically kept its expansion decisions tied to customer demand commitments, government incentive terms, and the availability of skilled labor before announcing capital spending.

The prospect of a second U.S. hub follows TSMC's flagship investment outside Taiwan: its fab campus in Phoenix, Arizona. That project has become the centerpiece of the company's U.S. manufacturing strategy and a benchmark for how advanced logic production can be transplanted onto American soil.

Any additional site would carry significant commercial and geopolitical weight. Washington has made domestic advanced semiconductor capacity a policy priority, and TSMC — as the dominant producer of leading-edge logic for customers including Apple, NVIDIA and AMD — sits at the center of that effort. A second hub would deepen TSMC's exposure to U.S. incentives while diversifying its manufacturing base away from Taiwan, where the majority of its advanced capacity remains concentrated.

For now, the details remain thin. MarketWatch's account establishes only that TSMC is looking at potential locations for an additional U.S. manufacturing site. No capital expenditure figure, capacity target, process node assignment, or construction timeline has been confirmed by the company.

Investors and supply-chain planners will watch for the signals that typically precede a formal TSMC site announcement: state-level incentive packages, land and utility negotiations, and statements from the company's Arizona leadership. Until TSMC confirms a location and commits capital, the second U.S. hub remains a roadmap item rather than a funded project — and the competitive map of American advanced chipmaking stays anchored, for now, in Phoenix.
