Memory chip giants reach trillion-dollar valuations as AI demand accelerates

Micron Technology and SK Hynix have reached market capitalizations of $1 trillion, joining Samsung, which hit the milestone earlier in May, according to the research summary.

The surge reflects intense global demand for memory chips used in artificial intelligence infrastructure. As AI systems expand, the hardware needed to support them has become a central focus for investors and the semiconductor industry.

The milestone marks a notable shift in market recognition for memory-chip makers, whose products are increasingly tied to the build-out of AI-enabling computing capacity. The gains point to rapid investment and expansion across the semiconductor supply chain as demand for AI infrastructure continues to rise.
