Micron and SK hynix valuation surge puts AI memory thesis under pressure

DigiTimes reported that Micron and SK hynix have reached trillion-dollar valuations after a major repricing of the memory sector. The item ties that shift to the debate around AI-driven memory demand, HBM's role as a bandwidth foundation for artificial intelligence, Chinese rivals adding capacity, and geopolitical competition around control of advanced memory supply. For RamTrend, the core signal is that investors are treating memory less like a purely cyclical commodity and more like a strategic AI infrastructure layer. That supports the pricing narrative for HBM and premium DRAM while supply remains constrained. The risk is that expanding Chinese capacity and any AI-demand reset could challenge the structural-growth view.
