According to Financial News, Samsung expects demand for its 8nm-and-below processes to exceed capacity, with utilization projected to surpass 100% in 2027; per Yonhap News, the number of 2nm projects secured in 2026 is expected to more than double YoY. According to Yonhap News, Samsung secured additional 2nm projects from major cloud service providers and AI/HPC customers in 3Q26, building on wins in the previous quarter. Per Seoul Economic Daily, Samsung plans to begin mass production of its second-generation 2nm mobile chip, the Exynos 2700, in 4Q26, while ramping up 4nm NPUs for a major customer. Per Central News Agency, Taiwanese ASIC firm Faraday said on October 27 that it had secured a U.S. cloud AI chip project using 2nm gate-all-around (GAA) technology, valued at tens of millions of dollars; Samsung will handle wafer fabrication, with Taiwanese foundry UMC and memory manufacturers also participating. Per Yonhap News, Samsung expects HPC to account for over 50% of its foundry revenue in 2027; as background, TSMC's HPC segment contributed 68% of total revenue in 3Q26. With advanced-node demand outpacing capacity expansion, Samsung is considering investments in new fabs in the U.S. and South Korea; per Green Economic Daily, Samsung plans to continue expanding 8nm, 4nm, and 2nm capacity, and the first Taylor foundry fab in the U.S. remains on schedule, with cleanroom operations underway and equipment installation and wafer runs in progress; per The Guru, the company is reportedly preparing to break ground on its second Taylor fab in November, with mass production targeted for 2030. Samsung expects double-digit foundry revenue growth and further earnings improvement in 4Q26. Per Digital Today citing Kiwoom Securities, the combined operating loss of Samsung's foundry and System LSI businesses is projected to shrink from KRW 6.742 trillion in 2025 to KRW 3.921 trillion in 2026, with quarterly losses estimated to have eased to KRW 777 billion in 3Q26.

According to the source title, UMC's utilization will top 90% in 2H26 as AI demand drives its expansion. The article states that United Microelectronics (UMC) saw operating momentum strengthen in the third quarter of 2026, as demand for artificial intelligence (AI), high-performance computing (HPC), communications, and automotive chips continued to drive the mature and specialty process markets. The source does not provide further capacity change details.
UMC CEO Jason Wang said at the Q3 earnings call that he expects 2027 to 'mark a turning point in our blended ASP trajectory,' with Foundry blended ASP expected to rise about 10% YoY; he also said AI exposure would 'probably see a quarter' of revenue in three years. These are management expectations/forecasts, not achieved results, and the source does not state the cause of the expected ASP turning point.

According to a repost by TrendForce, Samsung may end UMC's exclusive supply of display driver ICs (DDI) for Samsung's Galaxy OLED displays: amid tightening mature-node capacity, Samsung is reportedly eyeing GlobalFoundries as a second DDI supplier, with adoption possible as early as late 2027. The source does not state the cause. This remains a reported rumor with no confirmed contract or production fact.

According to ZDNet citing industry sources, Samsung is considering adding GlobalFoundries as a second foundry partner for display driver ICs (DDIs) used in its OLED Galaxy smartphones, potentially ending UMC's exclusive role in manufacturing the chips; GlobalFoundries-produced DDIs could appear in Galaxy smartphones as early as late 2027, with some lower- and mid-range Galaxy A series models possibly the first to adopt the chips. Samsung is reportedly evaluating GlobalFoundries' 22nm or 28nm nodes, which have compatible manufacturing facilities in Singapore and Germany. The stated cause: mature-node demand has outpaced supply since the second half of 2025, and per ZDNet, Samsung requested expedited DDI production for its Galaxy Z Fold8 after demand exceeded expectations following its July unveiling, but UMC was unable to fulfill the request because its 22nm DDI production capacity had already reached its limit; as a result, Samsung cut its planned Galaxy Z Fold8 component production volume for September by 10%, shifting the deferred volume to October. Per Economic Daily News, institutional investors expect UMC's 12-inch capacity utilization to reach 93% by the end of 2026, supported by rising 22/28nm DDI orders from Samsung System LSI and Novatek and demand for Apple Mac-related chips on 55/65nm nodes; per TrendForce, some capacity-constrained 12-inch mature nodes showed signs of 5–10% price increases between Q2 and Q3 2026, with broader price hikes expected in 2027. These items remain reports/evaluations or expectations, not confirmed actions.

According to a report by Chosun.biz (published 8 October 2026), AMD CEO Lisa Su is visiting South Korea to secure additional supply of HBM memory for AI accelerators, saying 'We are going to talk about our broader partnership' with Samsung executives; Samsung, meanwhile, reportedly 'hopes to turn its memory supply relationship with AMD into foundry' orders for logic chips. The visit comes a little less than seven months after the two companies signed a non-binding memorandum of understanding (MOU) this March, effective for three years and covering four areas: supply of next-generation memory products including HBM4 and advanced DDR5; co-development and optimization of memory solutions for AI and high-performance computing systems; exploration of foundry manufacturing opportunities for future AMD platforms; and co-optimization of advanced packaging and related semiconductor technologies. Samsung has become a principal supplier of HBM4 for AMD's Instinct MI400-series accelerators; expanding collaboration beyond memory supply is considerably more complicated, as it involves considerable efforts to design chips for Samsung Foundry's process technologies and risks associated with a product ramp at a new contract chipmaker — AMD's most recent Annual Report states that transitioning production of some products to new manufacturers may cause delayed product introductions, lower yields or poorer performance. AMD has already started shipments of its Instinct MI455 accelerators with 432GB of HBM4 onboard as well as rack-scale Helios AI systems to interested parties; Su said 'Samsung Electronics and SK hynix are key supply-chain partners for AMD,' that 'AI demand is extremely high' so AMD is planning its long-term supply chain with partners, and that 'It is important to plan three to five years ahead with our partners.' The article concludes that AMD is negotiating for more memory supply and whether it will take the risk of adopting Samsung Foundry beyond niche programmable chips 'only time will tell.'

TSMC reportedly cut 28nm monthly wafer starts by over 25% since early 2026, dropping from 200,000 to 150,000 units, as Fab 15A converts to a 4nm base. This capacity reduction aims to improve capital efficiency and steer customers to 12nm, creating spillover demand for UMC and Vanguard. The move signals a strategic shift away from legacy nodes, likely tightening supply and driving up prices for mature node wafers.

Major mature-node foundries (UMC, VIS, Powerchip, Nexchip) are reportedly planning price hikes of up to 10% as early as April. However, high inventory overhang and intense competition from Chinese suppliers continue to pressure pricing power and make broad-based increases unlikely. Watch: Mixed signals between planned price increases and persistent oversupply/competition create uncertain price trajectory.
