SK Hynix Stock Soars as AI Memory Demand Outlook Fuels Chip Rally

SK Hynix shares surged nearly 13% in Seoul on Wednesday, leading a broad rally in South Korean semiconductor stocks as easing U.S. inflation and renewed optimism over artificial intelligence (AI) memory demand boosted investor confidence.

Samsung Electronics climbed almost 8%, while chip equipment maker Hanmi Semiconductor jumped about 25% in early trading. The gains followed a strong overnight performance on Wall Street, where the S&P 500 and Nasdaq advanced after softer-than-expected U.S. inflation data and solid earnings from major banks improved market sentiment despite ongoing Middle East tensions.

The rebound comes after weeks of volatility in semiconductor stocks, driven by concerns that memory chip earnings growth could slow as price increases moderate in the second half of 2026. Investors have also questioned whether reduced capital spending by major U.S. cloud providers, increased financing needs, and aggressive capacity expansion plans by memory manufacturers could eventually ease the supply shortages that have supported the sector.

Despite these concerns, analysts remain bullish on the long-term outlook for AI-driven memory demand. Meritz Securities analyst Kim Sunwoo said DRAM suppliers are currently meeting only 75% to 80% of market demand, with shortages expected to worsen in the second half of 2026. He projects fulfillment rates could fall into the 60% range in 2027, while suppliers may still satisfy only around 70% of demand even after excluding speculative orders.

Kim believes tighter supply will continue lifting memory chip prices and earnings, creating favorable conditions for further gains in SK Hynix shares.

HSBC also maintained a positive outlook, citing improving profitability in AI services that should sustain strong cloud infrastructure spending. The brokerage expects the industry's shift toward three- to five-year supply agreements to improve earnings visibility and reduce volatility over the next several years.

Barclays reinforced the bullish sentiment by initiating coverage of SK Hynix's newly listed U.S. ADRs with an "Overweight" rating and a $330 price target after the ADRs surged nearly 28% on Nasdaq.

Goldman Sachs added that recent weakness in South Korean chip stocks was largely driven by ETF-related selling rather than deteriorating industry fundamentals. Meanwhile, SK Hynix CEO Kwak Noh-jung recently warned that the global memory market could face its most severe supply shortage in 2027, with demand expected to exceed production capacity well into the next decade.
