TSMC is reportedly evaluating an expansion of its manufacturing footprint in Texas, in addition to the company's previously announced plan to invest $265 billion in Arizona.

The report, surfaced by TechPowerUp, indicates that the world's largest contract chipmaker is considering additional US fabrication capacity in the Lone Star State. If the evaluation results in a committed project, it would mark a second major US manufacturing hub for the Taiwanese foundry beyond its flagship Arizona operations.

The $265 billion figure attached to the Arizona plan already represents one of the largest single-site semiconductor investments ever announced by any manufacturer. A potential Texas addition would extend that US build-out further, though the report characterizes the Texas effort as being at an evaluation stage rather than a confirmed commitment.

For TSMC's customers — which include the largest designers of advanced logic in the United States — additional domestic capacity options in a second state would broaden the geographic distribution of leading-edge manufacturing on American soil. It would also add redundancy to a supply chain that, until the Arizona project, concentrated TSMC's most advanced production in Taiwan.

The distinction between an evaluation and a commitment matters here. Semiconductor fabrication projects carry multi-year timelines, and site decisions typically hinge on incentives, utility availability, workforce pipelines, and customer demand commitments before capital expenditure schedules firm up. The report does not state that TSMC has finalized any Texas site, capacity targets, process technology, or investment amount.

What the report does establish is that TSMC's US expansion thinking now extends beyond Arizona. The company's Arizona plan, at $265 billion, already covers multiple fabrication facilities, and the addition of a Texas evaluation suggests the foundry sees room for more US capacity than its current announced program encompasses.

Texas hosts an existing semiconductor manufacturing ecosystem, and the state has long competed for large-scale fabrication investments against other US states offering incentive packages. Any TSMC project in the state would join that industrial base, though the report provides no specifics on locations under review.

For the broader market, the signal is straightforward: leading-edge wafer capacity in the United States continues to scale up, and TSMC is keeping its options open for where the next increment of that capacity lands. Customers weighing long-term sourcing strategies, suppliers to fabrication plants, and state economic development agencies all have a stake in how this evaluation resolves.

The reported evaluation also comes amid sustained political and commercial pressure to expand domestic semiconductor manufacturing in the United States. TSMC has been the single most significant corporate actor in that expansion to date, and a second-state project would deepen its role.

At this stage, the specifics remain unconfirmed. TSMC has not, per the report, announced investment figures, timelines, capacity, or process nodes for any Texas facility. The $265 billion Arizona plan stands as the committed baseline; the Texas effort exists, for now, as an option under study.

We will follow this story as additional details emerge from TSMC or from reporting on the evaluation's progress.
