Amid escalating technological competition between global powers, Asian AI hardware stocks faced intense selling pressure. These equities sold off sharply on Tuesday, July 28, 2026, following reports that China has achieved domestic production of Deep Ultraviolet (DUV) lithography machines. According to reports, this breakthrough poses a direct threat to the competitive moat and market share of established global hardware providers in the semiconductor supply chain.
This decline reflects growing investor concerns over the erosion of the competitive advantage held by traditional chipmakers in the face of rapid Chinese technological advancement. Per market data, major industry players were impacted, including ASML and Samsung (SMSN.L). Analysts suggest that China's success in domestic equipment manufacturing could compress margins for companies that have historically dominated this critical segment of AI infrastructure.
