SK hynix is the best positioned of the three memory makers because most of its revenue comes from HBM, which is not a commodity. Surging DRAM prices cannibalize Samsung's electronics arm, and Micron relies on commodity DRAM, where supply could catch demand by 2028. HBM4E, with hybrid bonding and custom base dies on advanced nodes, will rival leading logic chips in complexity, giving HBM makers pricing power. Per UBS, HBM goes from 15% of SK hynix's DRAM sales in 2026 to 58% by 2030. x.com
