Overview
- SK Hynix briefly passed Samsung in intraday trading on Monday, June 22, reaching about 2,082.5 trillion won in market value after a more than 340% year‑to‑date share rally.
- The rally is driven by the company's leadership in high‑bandwidth memory, a vertically stacked DRAM used in AI accelerators that speeds data transfer between processors and memory.
- SK Hynix has filed for a U.S. American Depositary Receipt offering valued at roughly 45.45 trillion won and set a target Nasdaq trading date near July 10 to raise funds for new fabs, packaging and equipment.
- Market risks include sharp price swings since the peak, Samsung's assertion that including its preferred shares keeps it larger, and execution challenges such as yield ramps, large factory builds and supply‑chain reliance on partners like TSMC.
- The rise reshapes Korea's market concentration and investor flows, with potential second‑order effects on domestic ETFs, workers' bonuses and global AI supply chains as SK Hynix expands production at home and in the United States.
