Taiwan Semiconductor Manufacturing Co. is weighing a new chipmaking campus in Texas that would sit **beyond** its already enormous Arizona expansion, according to people familiar with the matter cited by Bloomberg and Reuters — a tip that remains **early, anonymous-sourced, and unconfirmed by the company**.
Bloomberg reported on Oct. 1 that TSMC is looking at further overseas facilities to meet AI hardware demand and that a Texas project, if approved, would involve **multiple fabs** and **tens of billions** of dollars in new investment on top of the **$265 billion** TSMC has committed at its Phoenix-area site. One person told Bloomberg each plant would cost **at least $20 billion**; the same report cautioned that the plans are at an **early stage** and are not public. Reuters, a day earlier, said **two sources** described TSMC as **evaluating** a potential Texas investment **in addition to** Arizona, and that the plans **have not been finalized**.
TSMC has not verified either account. In a text message to Bloomberg, the company said: **“We have no comment on market rumors.”** Reuters separately reported that TSMC **declined to comment**. That non-response is the clearest on-record company stance available for the Texas tip as of Friday, Oct. 2, 2026.
What is confirmed is Arizona, not Texas. TSMC’s own Arizona site and July 2026 company and U.S. government announcements document a U.S. manufacturing roadmap centered on Phoenix. The company says investment there has grown from an early $12 billion framing to a planned **$265 billion**, described as the largest foreign direct investment in a U.S. greenfield project. Current Arizona plans underway include **six** logic wafer fabs, **two** advanced packaging facilities, and an **R&D center**, with July 2026 intent to add more fabs for **2-nanometer-and-below** technologies and packaging for U.S. customers. The first fab reached high-volume **N4** production in **Q4 2024**. Separately, the U.S. Commerce Department’s November 2024 CHIPS award provided up to **$6.6 billion** in direct funding (plus proposed loans) for an earlier three-fab / >$65 billion phase. Those facts establish the “beyond Arizona” baseline. They do **not** prove a Texas campus.
Bloomberg credited Taiwan’s **Economic Daily News** with first reporting that TSMC was considering Texas earlier the same week. English-language write-ups of that Economic Daily / UDN reporting — including Taiwan News and TrendForce on Sep. 29 — say unnamed industry sources pointed to **Dallas / North Texas** as a leading candidate, floated a scale of as many as **six** advanced wafer fabs, and said total investment **could exceed** the Arizona **$265 billion** figure because newer nodes are costlier. Those outlets also report that suppliers said they had **heard** discussion but had **not** been asked by TSMC to prepare, and that the **board had not approved** a final decision. Treat Dallas, six fabs, and “>$265B” as **UDN-chain, unnamed-source color**, not company guidance.
Bloomberg’s anonymous sourcing said a Texas decision could depend on Congress extending an advanced-manufacturing tax credit tied to the CHIPS framework and previously raised to **35%**, with the credit set to expire at the end of 2026. Senators Mike Crapo and Ron Wyden have said they are committed to an extension, Bloomberg noted, while a viable path this year was still unclear. That is legislative context attached to anonymous sourcing — not a signed Texas incentive package.
Texas already has a semiconductor base — without a TSMC fab campus on the books. Bloomberg and local/state coverage describe an existing Lone Star chip footprint: Samsung’s Texas manufacturing complex, Texas Instruments expansions (including Sherman), and other announced projects. A July 20 Texas Tribune survey of the state’s chip boom — TI, Samsung Taylor, Nvidia/Wistron plans, Elon Musk’s proposed “Terafab” — does **not** report a TSMC Texas fab campus. TSMC’s March 2025 U.S. investment press release does list a **design service center in Austin**, Texas, alongside a Camas, Washington fab and a San Jose design center. That is real Texas presence. It is **not** a wafer fab campus and should not be blurred into the tip.
Bloomberg also reported — separately from Texas — that TSMC has held conversations with Singaporean officials seeking semiconductor investment. The Singapore Economic Development Board declined to comment. Include only as attributed multi-site exploration, not as a substitute for Texas confirmation.
If a Texas multi-fab campus were eventually approved at the scale anonymous sources describe, it would be one of the largest additional U.S. foundry bets of the AI buildout and would extend TSMC’s American footprint past Arizona into a state that already markets itself as a semiconductor exporter. **None of that has been announced.** As of Oct. 2, the public record is: Tier-1 wires citing unnamed people; Taiwan media naming Dallas and very large dollar ranges; TSMC dismissing the chatter as market rumors; and a fully documented Arizona/CHIPS roadmap that the Texas tip is described as sitting **beyond**. The story is newsworthy as an early capacity-and-geography signal. It is thin on confirmation — and should be labeled that way.
