Industry Analysis
SK Hynix’s $28.2B Nasdaq listing is a geopolitical maneuver, not just capital raising. Full allocation to HBM4/HBM4E capacity and EUV tools will intensify demand for CoWoS packaging, TSVs, and molded underfill—forcing TSMC to accelerate 3nm CoWoS ramp. Despite no explicit U.S. restrictions, SK’s reliance on American investors heightens supply chain vulnerability amid U.S.-China tech decoupling. Micron is countering with HBM4 samples and EUV layer optimization via ASML, while Taiwan, China-based players remain bottlenecked by export controls on next-gen EUV scanners. Over the next 18 months, HBM will become the critical AI performance limiter; SK’s deep integration with NVIDIA’s Rubin platform secures pricing dominance and positions it to shape heterogeneous integration standards.
