The Democrats' sweeping victory in the November 2026 US midterm elections, securing control of both chambers of Congress, has prompted South Korean industries to reassess the implications for investment, trade, and technology policy. With South Korea and Taiwan both heavily dependent on semiconductors, AI, and electronics, Washington's policy direction carries significant consequences for their technology sectors.

China's National Integrated Circuit Industry Investment Fund Phase III (Big Fund III) is shifting its focus from targeted semiconductor investments to large-scale manufacturing and industry consolidation, with a CNY900 million (approx. US$134 million) capital injection into Silan Microelectronics' 12-inch analog chip project highlighting its latest priorities.

Samsung Display (SDC) is facing a shortage of automotive OLED panels supplied to Chinese EV maker Li Auto, prompting Li Auto to temporarily ship some new Mega vehicles with LCD panels. Strong vehicle sales have driven demand for high-specification displays beyond expectations, potentially giving SDC's automotive OLED business fresh momentum.

AI data centers are accelerating demand for high-speed optical communications, extending competition in the optical transceiver market beyond chips and module manufacturing to critical upstream materials. Indium phosphide (InP), a key substrate for high-speed optical lasers and optoelectronic devices, is increasingly sought after as 800G and 1.6T transceivers gain traction. With capacity expansion requiring time and product qualification presenting technical hurdles, securing InP wafer supplies has become a strategic priority for optical communications companies.

South Korean AI software developer Moreh says AMD Instinct MI355X GPUs running its inference software delivered more than twice the throughput of Nvidia B200 GPUs in company tests, as South Korea moves ahead with plans to build AI infrastructure combining AMD processors with locally developed chips.

South Korean cloud services provider Naver Cloud now runs AMD EPYC processors in about 35,000 servers and plans to deploy 144-core fifth-generation EPYC chips in its public cloud services in the second half of 2026. The company turned to AMD after high prices for Intel's higher-core-count processors slowed its server expansion.

Global memory supply constraints are creating opportunities for Chinese DRAM maker CXMT to expand its market share. As major international manufacturers prioritise high-bandwidth memory (HBM) and advanced DRAM, the tightening supply of mainstream DRAM is allowing CXMT to capitalise on domestic demand and capacity expansion.

Mitsui Chemicals is planning to acquire semiconductor materials maker JSR from state-backed Japan Investment (JIC) in a deal potentially worth more than JPY1.3 trillion (US$8.2 billion), which would rank as the largest acquisition in Japan's chemicals sector, according to reports by Nikkei Asia and Reuters on November 4, 2026.

China's efforts to build a complete domestic chip-design software stack are gathering pace through acquisitions and strategic investments. Empyrean Technology's latest transactions target gaps in verification, placement and routing, and logic optimisation, strengthening its challenge to established electronic design automation (EDA) suppliers.

South Korea's Supreme Court has upheld a KRW18.664 billion (approx. US$13.9 million) fine against Broadcom for pressuring Samsung Electronics into a long-term smartphone component purchasing agreement by disrupting supplies, bringing the US chipmaker's legal challenge to an end.

South Korean company UTI, the second supplier of ultra-thin glass (UTG) cover glass for Apple’s first foldable smartphone, the iPhone Duo, has begun shipments to Samsung Display (SDC), but mass production is running about one quarter behind schedule.

LG Energy Solution expects revenue to keep rising in the fourth quarter while profit dips. On its November 3 earnings call, it told analysts that its North American energy storage system (ESS) business is improving its profitability more slowly than the market expected. Executives also said tighter sourcing rules in the US and Europe are shaping how the battery maker buys materials, chooses customers, and plans its balance sheet.

Chinese commercial launch provider CAS Space launched its Kinetica-2 rocket at 8:15:25am on 3 November from the Dongfeng Commercial Aerospace Innovation Experimental Zone, placing 18 Spacesail Constellation satellites into their designated orbit. It was the rocket's first deployment mission for the low-Earth-orbit network, also known as G60 Starlink.

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.
