Korean Chip Stocks Plunge as AI Doubts and Fierce Competition Tank Memory Giants

Korean Chip Stocks Plunge as AI Doubts and Fierce Competition Tank Memory Giants​

South Korea's semiconductor sector saw a sharp correction on Tuesday, with major players like Samsung Electronics and SK Hynix experiencing significant declines amid mounting worries over the long-term viability of the AI-driven chip boom.

The broader market sentiment took a severe hit after reports intensified concerns regarding financing risks for AI infrastructure spending and rising competition from Chinese technology firms. The benchmark KOSPI was trading down around 8% as of 0120 GMT.

SK Hynix Sinks Below IPO Price Amid Investor Caution​

SK Hynix's U.S.-listed shares continued to slip, closing at $143.02, which is below the $149 initial public offering price. The downturn highlights the volatility faced by companies heavily tied to the current AI spending cycle.

Analyst insights suggest that this selloff reflects a confluence of concerns spanning financing and market competition. One key factor gaining attention is the rapid advancement in Chinese technology.

China's Rise Fuels Competition Fears in Global Memory Market​

Renewed worries emerged after reports surfaced that Chinese companies are developing domestic deep ultraviolet (DUV) lithography equipment. This development has amplified fears regarding intensified capacity expansion by Chinese memory makers, challenging global dominance.

Han Ji-young, an analyst at Kiwoom Securities, noted that while details concerning the involved companies and timelines remain undisclosed, this news significantly cooled investor sentiment in a sector already grappling with nervousness.

AI Infrastructure Financing Risks Weigh on Semiconductor Sentiment​

Investor caution is also mounting ahead of crucial earnings reports expected later this week. Han Ji-young pointed out that even strong performances, such as Samsung Electronics' recent results and Alphabet’s stock movement, failed to halt the sharp declines in semiconductor shares.

Further complicating investor sentiment was a report concerning Nvidia. The Wall Street Journal reported that Nvidia might offer a roughly $250 billion financial backstop for an OpenAI data-centre project. This news saw Nvidia shares drop nearly 5%, as investors began questioning the extent of the AI chip leader financing its own customers.

Low-Cost AI Models and Chinese Chip Stocks Intensify Market Scrutiny​

The growing popularity of low-cost, open-source AI models like Kimi K3 is also casting shadows over future demand projections. This trend raises questions about whether upcoming AI workloads might be less computationally intensive than previously assumed, potentially reducing the necessity for advanced AI chips and HBM (High-Bandwidth Memory).

The market scrutiny was heightened by the strong stock-market debut of Chinese memory-chip maker CXMT. The listing fueled pre-existing concerns regarding intensifying competition within the global memory industry.

Geopolitical Factors Underscore Technology Rivalry​

These market pressures occur against a backdrop of geopolitical tension. Apple’s reported lobbying efforts to allow the use of Chinese-made chips in some products, as noted by reports, further unsettled investors who are already concerned about China's accelerating technological capabilities.
