SK Hynix’s market capitalization reached $1.12 trillion on May 27, 2026, closing up 9.3% after an intraday surge of nearly 15%. Micron shares jumped 19-20% after UBS raised its price target. Year-to-date, Micron has risen more than 240%, SK Hynix over 215%, and Samsung between 149% and 165%. The KOSPI index hit record levels as investors piled into AI infrastructure plays.
All major tech firms are racing to build AI infrastructure, fueling massive demand for high-bandwidth memory. Analysts expect the memory chip supply gap to persist through 2028.
SK Hynix plans to raise about $29.4 billion via a Nasdaq ADR listing to expand AI semiconductor fabrication. The move drove an 11% stock jump and opens the door for US institutional investors.
The supply-demand imbalance grants these chipmakers significant pricing power. Equipment suppliers and packaging companies also stand to benefit. However, valuations have stretched-a 240% year-to-date gain prices in flawless execution. Geopolitical tensions over semiconductor exports to China remain a risk. Investors are watching whether the projected supply gap closes earlier than expected as capital spending surges.
