Core Summary
In June 2026, SK Hynix (000660.KS) surpassed Samsung Electronics (005930.KS) to become South Korea’s most valuable company. This achievement stems from the company’s 14-year continuous layout in the high-bandwidth memory (HBM) track, and its HBM business has been highly recognized by the market against the backdrop of the global explosion of AI computing power demand.
Editor’s Comments: This breakthrough broke Samsung’s long-standing leading position in South Korea’s enterprise market value list, confirming the commercial value of laying out core AI hardware tracks in advance. As a key memory component for AI servers, HBM demand is growing rapidly with the landing of AI large models, and SK Hynix’s success also provides a referential transformation path for other semiconductor enterprises. This incident also reflects that the global AI industry’s dependence on high-end memory chips is continuing to increase.
Why It Matters
First, this is a major change in South Korea’s semiconductor industry pattern. Samsung has long been the most valuable enterprise in South Korea, and its being surpassed by SK Hynix reflects the differentiation between the two enterprises in the AI hardware track. Second, the strategic value of the HBM track has been verified by the market, and SK Hynix’s success proves the return of long-term hard-core technology layout. Third, this incident highlights the strong demand of the AI industry for high-end semiconductor components, providing a reference signal for the development direction of the global AI hardware industry chain.
