Samsung Electronics, Micron Technology, and SK Hynix have each surpassed $1 trillion in market capitalization in May 2026, propelled by insatiable demand for the high-bandwidth memory chips that power artificial intelligence systems. Together, the trio now commands a combined valuation approaching $3 trillion.
Three trillion-dollar milestones in rapid succession
Samsung was the first to cross the threshold earlier in May, becoming only the second Asian company to reach a trillion-dollar market cap after TSMC.
Micron Technology followed on May 26, briefly touching the $1 trillion mark after its share price surged more than 18%. The catalyst was a price target upgrade from UBS analysts.
SK Hynix completed the trifecta the very next day, May 27, with shares climbing between 9% and 15% in a single trading session.
