SK Hynix saw its stock rise by 5.7% on Monday, pushing the company’s total market value to 2,082.5 trillion won (approximately $1.35 trillion) and briefly overtaking Samsung Electronics, which posted a modest 0.4% gain.
Share Surge and Market Capitalization
The overtaking marks the first time Samsung has lost the top spot since the early 2000s, a period during which it dominated the Korean market. Samsung argues that including its preferred shares would lift its full market cap close to 2,252 trillion won, keeping the rivalry extremely tight.
Investors have rewarded SK Hynix with a year‑to‑date stock increase exceeding 340%, a performance driven by its leadership in high‑bandwidth memory (HBM) technology. The price rally reflects confidence that the company’s specialized chips will sustain strong demand across multiple sectors.
Technology Driving Growth
HBM modules stack memory vertically, delivering higher data throughput while consuming less power than conventional DRAM. These chips serve as core components in AI accelerators built by Nvidia and are integrated into Google’s cloud infrastructure, boosting processing speed for machine‑learning workloads.
Because HBM is tightly coupled with AI hardware, manufacturers face high entry barriers, granting SK Hynix pricing power that commodity memory products lack. The firm now controls roughly 61 % of the global HBM market, with Samsung at 17 % and Micron holding the remaining 21 %.
