What's Happening
SK Hynix surged 11% to breach $1 trillion market cap, while Micron jumped 18% to hit the same milestone for the first time. Both memory-chip makers are riding explosive demand for AI infrastructure, with institutional capital flooding into semiconductor equities as data centers race to expand GPU and accelerator capacity.
Market Impact
The dual breakthroughs signal a structural revaluation of memory-chip suppliers as AI workloads require massive DRAM and NAND flash scaling. SK Hynix and Micron now command valuations previously reserved for foundries and fabless design houses, reshuffling sector leadership and attracting flows that had concentrated in NVIDIA and TSMC.
Broader Implications
South Korea's chip sector is reasserting dominance in a critical AI-era bottleneck. The rally validates supply-chain diversification away from Taiwan and validates memory as a secular growth vector, not a cyclical commodity.
