South Korea's KOSPI index fell 10.84% on 28 July, its worst day in five months, driven by a global chipmaker selloff that hammered SK Hynix and Samsung Electronics—which together represent over half the index's weight. Chinese competitor ChangXin Memory Technologies' market debut and reports of state-backed Chinese DUV lithography production deepened concerns about Korean chip makers' competitive position.
This Wire brief sits within Fusion42's coverage of Semiconductors, and 6 sources have reported it between 28 Jul 2026 and 9 Aug 2026.
◆ ◆ The Wire takeaway
Korean chip makers just lost 30% of their market cap in four weeks, and China's new DRAM player is now public and funded to scale. If you sell anything into Samsung or SK Hynix's supply chain—materials, tools, services—your customer's capex plans are about to compress sharply.
