South Korea's KOSPI index fell over 8%, triggering circuit breakers, after Chinese semiconductor maker ChangXin Memory Technologies (CXMT) listed on Shanghai Stock Exchange and reports emerged that Chinese firms have begun producing deep ultraviolet lithography equipment. Samsung Electronics and SK Hynix fell 11-12%, signalling investor concerns about Chinese competition in memory chips.
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
China has moved from buying lithography tools to making them; if you sell into Samsung or SK Hynix's supply chain, your customer's cost curve just inverted and so did your negotiating position. The Korean memory duopoly's pricing power is under structural threat for the first time.
