SK Hynix joins Samsung and Micron in crossing $1 trillion market capitalization as AI-driven demand boosts semiconductor sector

South Korean memory chipmaker SK Hynix reached $1 trillion in market capitalization. Samsung and Micron also recently crossed the threshold, with Micron reaching it just yesterday.

An exchange-traded fund of AI chipmakers increased 87% in value in the seven weeks since it launched, reflecting sector-wide momentum.

Some analysts predict a structural upswing in memory chip stocks, a major shift for an industry historically marked by volatility in both demand and stock price. However, skepticism remains among some market participants.
