TSMC is considering a multibillion-dollar semiconductor campus in Texas aimed at expanding production of AI chips, according to a report from The Business Times.

The plan, still at an exploratory stage, would extend the world's largest contract chipmaker's manufacturing footprint in the United States beyond its existing commitments in Arizona. TSMC has not confirmed the investment value, the site's exact location, the process nodes it would install, or a construction timeline. No capacity figures in wafers per month have been disclosed.

The reported deliberations come as demand for AI accelerators and high-end packaging outpaces available supply across the industry. TSMC fabricates the overwhelming majority of the world's most advanced logic chips, including silicon for Nvidia, AMD and major cloud providers, and every additional gigafab it plans is scrutinized as a signal of where future capacity — and pricing power — will sit.

Texas is already a growing center of US semiconductor construction. Samsung operates a large fab project in Taylor, near Austin, and Texas Instruments continues to expand its 300mm analog fabs in Sherman and Richardson. A TSMC campus in the state would place advanced foundry capacity alongside an established supplier and workforce base, and would deepen the cluster effect around Austin that state officials have courted for a decade.

For TSMC, the calculus is commercial as much as geopolitical. Building in the US costs more than in Taiwan — the company has said its first Arizona fab carried higher expenses than equivalent facilities at home — but Washington's CHIPS Act subsidies and customer pressure to geographically diversify supply have shifted the arithmetic. Customers designing AI systems want at least part of their advanced silicon fabricated closer to home.

The company's existing US strategy centers on Arizona, where it has committed to multiple fabs in Phoenix at an investment it has previously put above $65 billion. Any Texas campus would represent a second advanced-manufacturing hub in the country, a step that would signal confidence in long-term US demand for leading-edge logic rather than a one-site hedge.

The Business Times report frames the Texas deliberations specifically around AI chips, the segment now driving the industry's capital spending. AI accelerators, high-bandwidth memory support logic and networking silicon consume disproportionate shares of leading-edge capacity, and TSMC has repeatedly said it is racing to add advanced packaging and front-end capacity to meet customer forecasts. Coordinated capacity planning across sites — Taiwan, Arizona, Japan and potentially Texas — is how the foundry manages that squeeze.

Nothing in the report indicates a final decision. Multibillion-dollar fab projects typically pass through years of site evaluation, incentive negotiation and customer commitments before groundbreaking, and TSMC routinely studies locations without proceeding. The company has also shown discipline in pacing construction to actual demand signals rather than building ahead of firm orders, as it did when it adjusted the ramp schedule of its first Arizona fab.

If TSMC proceeds, the decision would mark one of the largest single foreign investments in US semiconductor manufacturing and would intensify competition for construction labor, ultra-pure water, power and skilled process engineers across the Southwest. It would also sharpen the contest with Intel and Samsung for subsidized US advanced capacity at a moment when AI chip demand shows little sign of cooling.
