SK Hynix and Micron reach $1 trillion in market capitalisation for the first time as investors drive shares higher amid a sustained memory-chip upcycle. On Wednesday, SK Hynix stock rises sharply in South Korea—reports cite gains of around 11% to 13%—pushing its 12-month increase to more than 1,000% and making it the third Asian company to surpass a $1 trillion market value. Bloomberg reports that market participants and companies view the current memory-chip surge as potentially lasting longer than prior cycles, citing a “groundswell of opinion” that conditions could differ from historical patterns. The reporting characterises the momentum as part of a broader memory-chip frenzy that lifts both SK Hynix and Micron into the $1 trillion “club.” While past semiconductor cycles have often ended after rapid expansion, the coverage indicates investor expectations for continued strength in demand and pricing. The articles present the milestone as linked to prevailing sentiment around the memory sector’s near-term outlook, rather than any single company-specific event.
