On Monday SK Hynix briefly surpassed Samsung Electronics after its shares jumped
5.7% and its market value reached KRW 2,082.5 trillion (about $1.35 trillion);
Samsung rose 0.4% to KRW 2,081.3 trillion. Samsung had held the top spot since
2000. The move reflects a surge in memory-chip demand from US tech giants
building AI data centers, tighter supply and rising prices; both Korean
chipmakers reported record profits. Year-to-date SK Hynix has gained more than
340%, versus roughly 200% for Samsung.
