$SKHY SK Hynix achieved the largest-ever foreign US listing by raising $26.5 billion through its Nasdaq ADR debut



The South Korean chipmaker SK Hynix is a dominant supplier of high-bandwidth memory (HBM) chips to Nvidia and powers AI servers. It holds a leading ~56% share of the HBM market. The company briefly hit $1 trillion valuation earlier in 2026, overtook Samsung in market value at times, and currently sits around $990B–$1.2T depending on the trading session and ADR/KRW share dynamics.

Proceeds are funding new fabrication capacity in Korea as South Korea pours over $500 billion into expanding its chip industry to meet surging AI demand.

South Korea’s stock market has been one of the top performers in 2026, up significantly year-to-date, fueled heavily by SK Hynix, Samsung, and the broader AI/memory boom.

This listing highlights continued global investor appetite for AI infrastructure plays even in a mixed broader market environment.
SKHY-8.93%
SK Hynix-10.99%
NVDA0.33%

Snatching the No. 1 spot in market value from Samsung, Hynix’s comeback this time has been nothing short of impressive—it's got Nvidia’s back and is holding on tight.
