SK Hynix Nasdaq debut raises $26.5B; HBM vendor signals AI memory scarcity through 2030

SK Hynix, the world's leading high-bandwidth memory manufacturer, completed its American depositary receipt (ADR) listing on Nasdaq July 10–14, 2026, raising $26.5 billion at $149 per share—the largest ever U.S. IPO by a foreign company and second-largest share sale in U.S. history after SpaceX's $86 billion offering. The offering was oversubscribed 7x, reflecting intense institutional demand for exposure to AI-driven memory shortages. Shares rose 12.8% on debut (SKHYV, then SKHY), though volatility persisted as the stock gave back some gains mid-week.

SK Hynix controls roughly 58–60% of the global high-bandwidth memory (HBM) market and supplies Nvidia as a lead customer. The Seoul-listed stock had already risen nearly 359% through June 2026 on the back of record Q1 2026 revenue of ₩52.6 trillion (up ~200% YoY) and operating margins exceeding 70%. The company signaled through management that multi-year customer demand already exceeds planned supply, and that DRAM and HBM supply constraints are expected to persist until 2030. Proceeds will fund new fabs in Yongin and advanced packaging capacity in Cheongju, South Korea.

For AI infrastructure investors and operators, SK Hynix's debut underscores the memory supply crisis: the company is betting that it remains structurally short of supply for years, not quarters. Analysts have raised price targets citing the durability of the AI supercycle, though consensus targets remain modest, signaling disagreement on how long the cycle lasts. The listing removes a major barrier to U.S. investor participation and re-rates memory from a cyclical commodity toward AI infrastructure—a signal that the scarcity narrative is taking hold.
