SK Hynix $26.5B Nasdaq debut, largest foreign IPO; stock up 13% day-one
SK Hynix raised $26.5 billion in its U.S. Nasdaq debut on July 10, 2026, the largest first-time share sale ever by a foreign company, surpassing Alibaba's $25 billion IPO in 2014. The South Korean memory chipmaker sold 177.9 million American Depositary Receipts (ADRs) at $149 each, with shares opening at $170 and closing Friday at $168.01, a 12.8–13% gain, fueled by seven-times oversubscribed demand. The listing ranks second-largest in U.S. history after SpaceX's $85.7 billion Nasdaq debut in June 2026.
SK Hynix plans to deploy the proceeds into manufacturing capacity expansion, funding its 1.1 trillion won (roughly $733 billion) mid-to-long-term investment roadmap designed to meet explosive AI-driven demand for high-bandwidth memory (HBM) and DRAM. The company holds approximately 57–60% of the global HBM market critical to AI accelerators, with Q1 2026 revenue up 198% year-over-year and net profit margins exceeding 70%. Micron is simultaneously committing $250 billion through 2035 to U.S. domestic fabs, and Samsung/SK Hynix jointly pledged $518 billion for South Korean capacity as regional fabs race to close supply gaps.
For infrastructure teams, SK Hynix's Nasdaq listing signals that HBM supply tightness will persist into 2028 as new fabs take 2–3 years to ramp. The company has sold out its entire 2026 memory supply, granting it rare pricing power in a notoriously cyclical industry. However, analysts warn of potential boom-bust risk: the massive multi-billion-dollar fabs now under construction may overshoot demand if AI capex cools or efficiency gains reduce per-model memory requirements. Architects should plan long-term capacity agreements now if they cannot tolerate memory supply volatility.
