SK Hynix breaks Alibaba's US listing record — but HBM customers will wait until 2028 for the capacity it funds

SK Hynix’s $26.5B Nasdaq offering is less a financial milestone than a geopolitical maneuver to secure advanced packaging and DRAM capacity amid tightening U.S. export controls. The capital will accelerate HBM4 and CoWoS-like integration, directly pressuring Micron’s AI memory roadmap and forcing TSMC to rebalance its 3D stacking capacity. However, restrictions on equipment exports to its Xi’an fab could erode over 10% of capital efficiency through compliance overhead. Samsung, unwilling to cede further HBM market share, is likely to fast-track GAA-based DRAM prototyping as a countermeasure. With HBM supply not scaling meaningfully until 2028, AI chipmakers will intensify investments in heterogeneous integration and near-memory computing—making the true long-tail impact not about bits shipped, but about reshaping the architectural dependency of the entire AI hardware stack.
