South Korean billionaire's risky bet pays off, as SK Hynix debuts in New York

SK Hynix made its New York debut, marking a milestone for the chipmaker whose decade-long bet on high-bandwidth memory (HBM) chips paid off as it became the world's biggest HBM producer and a critical Nvidia partner. Nvidia CEO Jensen Huang told reporters in Seoul that SK is their largest memory partner and the AI industry could not have developed as it did without SK. The article flags concerns about memory oversupply and cyclicality, noting that SK Hynix and Samsung have pledged hundreds of billions of dollars in new South Korean chip plants to meet surging demand.
