SK Hynix, the South Korean memory chipmaker, just crossed a $1 trillion market capitalization.
The milestone, reached around May 26-27, makes SK Hynix the second South Korean company to hit the trillion-dollar mark, following Samsung Electronics earlier this month. Micron Technology joined the party around the same time. Three memory chipmakers crossing $1 trillion in the same month isn’t a coincidence. It’s a verdict on where the tech industry’s money is flowing.
The numbers behind the surge
SK Hynix’s stock has risen over 200% year-to-date in 2026. That comes on top of a 274% increase in 2025.
The company’s market valuation briefly peaked at approximately 1,624 trillion won, or around $1.08 trillion.
