TSMC Eyes Texas for Second US Chip Hub, $265B+ Planned

Update, Sept. 30

Three details sharpened since publication. First, markets are unimpressed: TSMC shares drifted 0.4% lower in premarket trading the morning after the report broke (MarketWatch, Sept. 29), suggesting investors are treating this as evaluation, not commitment. Second, Korean coverage added a strategy detail: TSMC is said to be envisioning a "southern semiconductor dual-core corridor" linking Arizona and Texas — Arizona as the core wafer-manufacturing hub, Texas as the node plugged into the region's advanced chip ecosystem (Herald Business, Sept. 29). Third, the Texas customer pull is concrete: Apple, one of the four companies named as pushing for U.S. production, will buy more than 100 million chips from TSMC Arizona this year, and in February announced it would double its Houston manufacturing facility, producing the Mac mini in the United States for the first time (AZCentral via MacTech, Sept. 29). ChosunBiz's Sept. 29 write-up corroborated the six-fab figure and stressed that TSMC has still announced nothing.

TSMC's Next American Bet May Be Bigger Than Its Last

The world's most important chipmaker is quietly scouting its second American home. Taiwan's Economic Daily News reported on September 28 that TSMC is reviewing the Dallas, Texas area as the site for a second advanced U.S. manufacturing complex — a campus that could hold up to six leading-edge wafer fabs and an investment tally that may surpass the $265 billion the company has committed to Arizona. The report, citing semiconductor equipment-industry sources, was quickly corroborated by TrendForce, SemiMedia, ChosunBiz, and MarketWatch.

If it happens, it would be one of the largest single-company industrial investments in American history. But the operative phrase is "if." TSMC has not announced the project, its board has not approved anything, and the supply chain has not been told to prepare. What follows is what the reporting actually says, why Dallas makes strategic sense, and why the politics of the next five weeks may matter more than the engineering.

What the report actually says

According to Economic Daily News — Taiwan's UDN media group — semiconductor equipment suppliers say TSMC is evaluating Dallas and the broader North Texas region for a second U.S. production complex beyond Phoenix. Up to six advanced wafer fabs are under discussion, alongside the infrastructure that would support them. Because the new fabs would likely adopt process nodes more advanced than what TSMC currently runs in Arizona, industry estimates put the price tag above the $265 billion planned for the Arizona cluster.

TrendForce's September 29 write-up added an important texture: rumors of a Texas fab had already been circulating inside the semiconductor supply chain, with multiple unnamed supply-chain companies telling the outlet they had heard similar discussions from other suppliers. Yet TSMC has not notified any of them or asked for preparations — the classic signature of a project still in the evaluation phase. SemiMedia likewise described the plan as being at "an early evaluation stage," noting that final site selection, investment size, and construction schedules remain uncertain.

The drivers named in the reporting are the company's biggest American customers. NVIDIA, Intel, AMD, and Apple have all pushed TSMC for more U.S.-based production, according to Economic Daily News. That makes intuitive sense: those four companies sit at the center of the AI hardware boom, and every one of them is under Washington's pressure to source critical components domestically.

The tariff arithmetic behind a Dallas campus

The clearest lens on this story is trade policy. The Trump administration has renewed threats of tariffs as high as 200 percent on chips made overseas, according to TrendForce's reporting — and crucially, Commerce officials are said to be designing a tariff-offset program that would give preferential treatment to companies investing in U.S. chip production. A credible Texas pledge would put TSMC firmly on the right side of that line.

Consider TSMC's exposure. U.S. customers accounted for 75.64 percent of the company's revenue in the first half of 2026, per the Taiwanese press figures cited by SBS News and repeated across the coverage. Three of every four dollars TSMC earns come from American buyers. When most of your customers are American, a tariff on imported chips is, for practical purposes, a tariff on your own business. Building in the United States is not charity; it is revenue defense.

This dynamic also explains the timing. With the U.S. midterm elections roughly five weeks away, Washington's industrial-policy machinery is running hot — and a megaproject announcement in Texas is the kind of concrete, jobs-and-concrete commitment that resonates in a way abstract trade pledges do not. As one industry source told TechSoda, "it is difficult to say where things stand, especially before the midterm elections." The political calendar is a variable in the boardroom, not just in Washington.

Why Dallas

Dallas–Fort Worth and the surrounding North Texas region are already known inside the industry as the "Silicon Prairie." Texas Instruments continues to expand its 300mm manufacturing footprint there, and the region hosts established clusters of wafer manufacturing, semiconductor materials, equipment and engineering suppliers, optical communications, and defense electronics, with Coherent, Samsung, and Tesla among the companies operating in the area, per TrendForce's roundup.

For TSMC, that matters enormously. A fab is not a standalone building; it is the apex of a supply chain that includes specialty gases, photoresists, precision tools, and thousands of trained technicians. Texas offers a state government that courts heavy industry aggressively, relatively cheap land and power, and an existing labor pool that has been fabricating chips for decades. Austin and Houston have also been mentioned in earlier speculation, according to TechSoda, but the current reporting centers on Dallas.

There is also a strategic logic in going multi-state. Arizona has given TSMC a working template for U.S. construction — including hard lessons about labor practices, permitting, and cost overruns. A second campus in a second state diversifies construction risk, talent pipelines, and political relationships, while keeping the company close to different customer and logistics corridors.

What TSMC is already building in Arizona

To appreciate the scale of what "bigger than Arizona" would mean, it helps to inventory Arizona. TSMC's American ambitions have scaled at a pace that makes most corporate expansion plans look quaint: the company announced a $12 billion investment in Phoenix in 2020, and by July 2026 that figure had ballooned to $265 billion, according to CryptoBriefing's reporting.

The planned Arizona complex now includes six wafer fabs, two advanced-packaging facilities, and a dedicated research and development center, per TrendForce. Production is already real: Fab 1 has been running volume production of 4-nanometer chips since late 2024, Fab 2 is on track for 3-nanometer production by late 2027, and 2-nanometer technology is slated for subsequent phases. TSMC's stated target is for Arizona to eventually hold roughly 30 percent of its global 2-nanometer-and-smaller capacity.

Industry analysis suggests a Texas campus would need to be bigger because it would start from a more advanced node. Advanced fabs cost more per wafer of capacity — more extreme-ultraviolet lithography tools, more complex process steps, more supporting infrastructure. A Dallas complex at sub-2-nanometer nodes could credibly exceed $265 billion over a full build-out even with the same fab count.

The caveats, stated plainly

None of the following has happened: TSMC has not officially announced a Texas project. Its board has not decided anything. No supplier has been asked to prepare equipment, facilities, or construction timelines. Economic Daily News itself noted that TSMC had not responded to a request for comment as of press time on September 28.

This is the standard lifecycle of a TSMC expansion rumor. The company evaluates sites constantly — in Japan, Germany, Arizona, and now apparently Texas — and only a fraction of evaluations become announcements. Equipment-industry sources are genuinely informed, because suppliers hear about procurement timelines early; but they also have an incentive to read every feasibility study as a pipeline. Treat this as a serious evaluation, not a decision.

There is also real execution risk. TSMC's Arizona construction has been a learning experience in cost discipline and workforce development. A Texas build would inherit those lessons but also the same structural challenges: higher U.S. construction costs, a tight pipeline of skilled fab labor, and the sheer operational complexity of running leading-edge processes oceans away from Hsinchu's engineering base.

TSMC Texas fab FAQ: is the Dallas campus confirmed?

Is the Dallas campus confirmed? No. The report comes from Taiwan's Economic Daily News (UDN), citing equipment-industry sources. TSMC has announced nothing, and its board has made no decision.

Where in Texas would it be? The Dallas area, according to the report — the North Texas region the industry calls the "Silicon Prairie."

How many fabs, and how much would it cost? Up to six advanced fabs, with investment that could exceed the $265 billion Arizona complex.

What would the Texas site actually build? Advanced fabs plugged into North Texas's chip ecosystem. Korean coverage describes the concept as a "southern semiconductor dual-core corridor" — Arizona as the core wafer-manufacturing hub, Texas as the advanced node.

What's the biggest obstacle? Tariffs — Trump's 200% threats and the offset program that a second U.S. hub would help unlock — and market skepticism: TSM drifted 0.4% lower in premarket trading after the report (MarketWatch, Sept. 29).

What to watch next

Three milestones would signal that this is moving from evaluation to commitment. First, a formal announcement or board-level disclosure — TSMC's public statements are the only ones that count. Second, supplier notifications: when equipment vendors start allocating tools and construction partners start hiring in North Texas, the project is real. Third, the federal tariff design: if Commerce finalizes a tariff-offset program tied to U.S. production commitments, expect a wave of formal pledges from not just TSMC but its peers.

For context on how aggressively Washington is pushing memory and logic manufacturing onto U.S. soil, the parallel SK Hynix–Intel US memory talks show the same forces at work: customer pressure, tariff exposure, and a White House determined to see fabs rise on American ground. Logic and memory are converging on the same map.

Whether Dallas becomes the second node in TSMC's American network will be decided in boardrooms in Hsinchu and negotiating rooms in Washington — but the direction of travel is no longer in doubt. The world's most advanced chips will increasingly be made in the United States, and the only questions left are how many fabs, how soon, and at what price.
