SK Hynix overtakes Samsung to become South Korea's most valuable company on HBM boom
SK Hynix has overtaken Samsung Electronics by market capitalisation to become South Korea's most valuable listed company. The chipmaker's value has climbed sharply this year as demand for high-bandwidth memory (HBM) has surged. The reshuffle also reweights the chip-heavy structure of the KOSPI index.
SK Hynix has overtaken Samsung Electronics by market capitalisation to become the most valuable listed company on the Korea Exchange. The firm has been a direct beneficiary of the 18-month surge in demand for high-bandwidth memory (HBM) integrated into Nvidia's accelerators.
Samsung Electronics, by contrast, presented a more cautious picture in the latest quarter as smartphone and television-panel businesses softened; on the HBM side, it is still working to claw back market share. Analysts have flagged the possibility of double-digit net-income growth at SK Hynix in 2026.
The reshuffle also reweights the semiconductor exposure of the KOSPI index; passive-fund flows are tilting toward SK Hynix while short-term technical pressure on Samsung may persist. The Korean won drew modest support from the news during the morning session, edging up against the U.S. dollar.
