TSMC has sent teams to assess a potential Texas expansion and confirmed talks regarding Terafab. TSMC CEO C.C. Wei stressed that "the fab must be run by TSMC," while Elon Musk says his companies will build and operate Terafab, leaving a disagreement over who would run the fab. The expansion assessment remains a potential plan, and neither the outcome of the talks nor the final operator is settled. The source does not state the cause.

Reported on October 15, 2026: TSMC CEO C.C. Wei highlighted the company's ability to mass-produce 5x reticle-size packaging with strong yields, a feat he says rivals have yet to match, and signaled TSMC could step in if rival providers, including Intel's EMIB, struggle to meet customer demand. TSMC is doubling down on advanced packaging despite its own CoWoS capacity constraints, with 9x solutions under development and 14x on the horizon. According to an Anue report in August, TSMC Vice President of Advanced Packaging Technology and Service Jun He said the company's 5.5x reticle-size CoWoS technology has already entered high-volume production, with yields exceeding 98% for multiple AI customers and reaching as high as 99% for some; advancing one generation per year, TSMC expects to scale up to 14x reticle-size packaging by 2029, according to Anue. Wei also reportedly expects the next-generation A14 (1.4nm-class) process to become larger than N2 on stronger customer engagement, slated for risk production in 2027 and high-volume manufacturing in 2028. Intel is reportedly accelerating its 14A roadmap: CEO Lip-Bu Tan is reportedly targeting risk production as early as 1Q27, while Intel's official timeline remains more conservative, with internal 14A products planned for 2H27 and high-volume manufacturing in 2028. According to a July TechPowerUp report citing KeyBanc, Intel reportedly plans to manufacture 80–90% of its upcoming Nova Lake compute tiles internally, reversing an earlier dual-source strategy under which TSMC's N2 process was expected to handle 60–70% and Intel's 18A the rest. Wei stressed that the foundry treats all customers equally, whether IDMs or fabless designers, while factoring their internal manufacturing capacity into its own capacity planning.
Topco Scientific (TSC) is evaluating a new base in Boise, Idaho, and plans to strengthen its local technology, engineering, and supply chain capabilities to pursue memory and advanced-process opportunities. The company already operates service bases in Phoenix, Arizona, and Dallas, Texas. The source links this plan to the US entering a fresh wave of chip manufacturing expansion and Micron ramping up advanced memory investment. The event remains at the evaluation/planning stage and is not a confirmed implementation outcome.
TSMC is considering expanding its U.S. manufacturing footprint into Texas, with growing demand from American customers prompting the company to evaluate additional capacity beyond Arizona. On the October 15, 2026 third-quarter 2026 earnings call, Chairman and CEO C.C. Wei said TSMC has already sent teams to Texas to assess conditions for a potential expansion; he noted TSMC has a large U.S. customer base with clients urging the company to expand in the country, and highlighted support from the U.S. government as a factor in considering further investment, with Texas now among the locations under evaluation. On Terafab, Wei confirmed the company is in discussions over the project but said the outcome remains uncertain, and emphasized that any fab involving TSMC would have to be operated by the company itself. This follows a different position from Elon Musk on October 7: according to Reuters, Musk said his companies would build and operate Terafab, suggesting TSMC could potentially sublease part of the facility but would not take an operational role, leaving the potential partnership structure uncertain. Separately, according to Reuters citing Bloomberg, Intel CEO Lip-Bu Tan said Intel would remain involved in the Terafab project. TSMC also expects gross margin dilution from overseas fabs to be closer to 2 percentage points in 2026, widening to 3-4 percentage points over the next few years as more overseas fabs ramp up; it has nearly 20 fabs worldwide, including 13 in Taiwan and approximately five to six overseas facilities under construction. To support sustained demand for its N3 node, volume production at its new Tainan Science Park fab remains on track to begin in the first half of 2027, and it has decided to add another fab in Tainan with volume production scheduled for the first half of 2028; its second Arizona fab has completed construction with equipment installation underway and volume production expected in the third quarter of 2027, slightly ahead of schedule; and TSMC plans to begin 3nm volume production at its second fab in Japan in 2028.
King Yuan Electronics (KYEC) has signed a prepayment agreement with Nvidia to support its wholly owned US subsidiary, AeternZ, in building local testing capacity, giving Nvidia early access to AI chip testing capacity in the US. The move further clarifies KYEC's plans to invest in the US, with Fort Worth, Texas, reportedly emerging as the likely site of its operations in the country. The event remains at the agreement/plan stage and the capacity is not yet built.
