Breaking: SK Hynix Posts Sixth Straight Record Profit of 83.3 Trillion Won - 조선일보

Six consecutive record quarters is not an earnings story—it is a structural declaration. SK Hynix has converted DRAM from a cyclical commodity into the binding constraint on AI compute. With over 60% HBM share, NVIDIA's accelerator roadmap is anchored to one supplier's yield curve. That is technology-sovereignty dependency, not a supply relationship. Upstream, the HBM4 2026 production node is forcing capex reallocation across TSV and hybrid-bonding tooling; ASML and Lam Research order books will restructure around 16-to-20-layer stacking. Downstream, storage's share of AI capex is migrating from roughly 15% toward 25%+, turning the 'memory wall' from an academic paper into a procurement variable. On risk, US export controls bifurcate the global HBM market into compliant and gray pools. SK Hynix's mainland China revenue faces rising compliance costs. Deeper still: a Korean firm now holds the memory chokepoint of AI infrastructure, reshaping geopolitical leverage in ways Washington has not fully priced. Competitively, Samsung's repeated HBM3E qualification delays expose advanced-packaging yield gaps. Micron trails by at least two customer-validation cycles. NVIDIA's multi-sourcing is a bargaining lever, not a genuine substitute. Over the next 18 months, the HBM4 layer-count race will set the energy-efficiency ceiling for next-gen AI silicon. The 'super-cycle' narrative is being replaced by a structural premium. This is not a cycle. It is a paradigm shift.
