Industry Analysis
SK Hynix overtaking Samsung in market cap reflects AI infrastructure's acute demand for HBM memory, creating a technology gap that rewards focused R&D. This shift forces upstream materials (e.g., TSV, CoWoS substrates) and downstream AI server designs to adapt rapidly. Tightening U.S.-ROK export controls raise compliance costs, yet SK’s storage-centric model avoids the cross-sanction risks inherent in Samsung’s diversified foundry and logic chip operations. Samsung will likely divest non-core memory assets and leverage its 3nm GAA process to lock in NVIDIA partnerships. Over the next 18 months, the HBM4 standard rollout will trigger a capacity race; SK Hynix’s lead hinges on securing advanced packaging capacity from Taiwan, China—if bottlenecked, its advantage may erode swiftly.
