AI demand continues to heat up while major global memory makers shift capacity toward higher-value products, keeping niche memory supplies tight in the near term. China-based IC design firm GigaDevice Semiconductor Inc. said niche DRAM prices have risen sharply, curbing some consumer-electronics demand and easing supply pressures slightly, but that limited supply will keep prices elevated for some time.

A loophole in US export controls reportedly lets high-bandwidth memory (HBM) made by Samsung Electronics and SK Hynix reach China's AI chip industry. The loophole shows how much Huawei's next-generation processors still depend on foreign memory, while China's domestic suppliers struggle to close the gap.

Apple's Greater China revenue rose 21% year-over-year to a record US$17.5 billion in the fourth quarter of fiscal 2026, ended September, while full-year revenue increased 28%, driven by the launch of the iPhone 18 Pro series. The results underscore the flagship iPhone's continued competitiveness in China, while rising memory prices threaten to pressure profit margins and growth.

DRAM manufacturer Nanya Technology reported consolidated revenue of NT$46.476 billion (US$1.42 billion) in October 2026, up 3.07% from September and 487.73% year-over-year. Driven by continued increases in DRAM prices, monthly revenue reached a record high for the 12th consecutive month. Consolidated revenue for the first 10 months totaled NT$311.761 billion, up 602.15% year-over-year.

Samsung Electronics' and SK Hynix's dependence on sustained AI infrastructure spending is bringing customer financing risk into focus. As demand for high-bandwidth memory and server DRAM lifts their businesses, industry discussion of possible financial support for AI customers raises a further issue: protecting future chip orders could also expose suppliers to customers' investment risks.

SK Hynix's plans for a US$45 billion NAND investment in New York face a regulatory hurdle as Washington holds back approval for American chipmaking equipment needed at the company's Dalian plant in China, putting the proposed US expansion under pressure ahead of a year-end tax incentive deadline.

AI data centers are increasing demand for high-speed optical communications, making optoelectronics supply chains increasingly strategic. Marvell's announced acquisition of Lumentum highlights chipmakers' growing integration of optical technologies. Huawei has pursued its own supply-chain strategy through sustained equity investments by Hubble Technology.

Onsemi is pitching its AI data center business as a play on the entire power path inside an AI rack, and for now it is prioritizing that business and industrial customers over automotive restocking. On its third-quarter 2026 earnings call, the US chipmaker repeated that AI data center revenue should double in 2027 from a higher 2026 base. It also guided automotive revenue down by a high single-digit percentage in the fourth quarter, which management called a supply decision, not a strategic one.

AMD is pursuing a larger role in AI infrastructure by combining its growing server CPU franchise with rack-scale systems, broadening its offering beyond individual processors. The company's earnings call highlighted demand for CPUs that run agents and support accelerators, alongside the first revenue shipments of Helios systems built around its newest AI GPUs.

Dutch chipmaker Nexperia is seeking US$2 billion in damages from its Chinese owner Wingtech and three other defendants, alleging they established a competing supply chain in China that disrupted its business.

AMD expects company-wide revenue to grow more than 80% in 2027, an expansion increasingly dependent on delivering AI systems and server processors at scale. Data centers already generate nearly two-thirds of sales, but management's outlook leaves execution and product mix central to how much demand converts into revenue and profit.
