How SK Hynix's bet on a niche memory chip made it more valuable than Samsung - Yahoo Finance

SK Hynix's strategic bet on high-bandwidth memory (HBM) chips, initially dismissed as a niche market, ultimately led to its market capitalization surpassing that of Samsung Electronics. In 2012, SK Gr... Read original →

SK Hynix’s HBM dominance stems from correctly anticipating AI’s memory bandwidth bottleneck. This bet triggered a cascade: TSMC’s CoWoS capacity surged, while AMD and Intel accelerated HBM integration into their AI accelerators. Geopolitically, U.S. export controls now cover HBM3E, forcing SK Hynix to reconfigure its Nanjing fab for compliance—raising costs. Samsung is rushing HBM4 to counter SK’s near-exclusive Nvidia supply, but lags in yield; Micron leverages Microsoft’s custom Azure chips as a hedge. Over the next 12–24 months, HBM will migrate from training to inference workloads, spurring new form factors like LPCAMM. Without converting its lead into ecosystem control or standards influence, SK Hynix’s market cap edge may prove transient.
