SK hynix Inc. reached a $1 trillion market capitalization for the first time on May 28, 2026.
Shares jumped as much as 14.9% during intraday trading. Global demand for high-bandwidth memory (HBM) chips used in artificial intelligence drove the rally.
The company joins Samsung Electronics and Micron Technology in the trillion-dollar valuation club. This surge narrowed the market value gap between SK hynix and its primary competitor, Samsung.
Analysts attribute the growth to demand for advanced chips linked to NVIDIAβs AI technologies. Persistent supply shortages are expected to keep prices elevated and maintain investor optimism.
