$26.5B SK Hynix Nasdaq share sale surges 14% on first day

For Wall Street, SK Hynix's historic $26.5 billion capital raise is a masterclass in timing. By tapping the Nasdaq at the crest of an AI investment wave—even as semiconductor stocks correct—the South Korean chipmaker secured a huge war chest and validated the enormous premiums U.S. investors are willing to pay for pure-play AI memory exposure. This offering not only shattered Korean equity markets' scale barriers but also signals that the AI-fueled liquidity party hasn't ended yet.

SK Hynix, the world’s top supplier of high-bandwidth memory (HBM) chips essential for AI computing, pulled off the second-largest U.S. share sale in history on July 10, 2026, raising $26.5 billion through a Nasdaq listing of American Depositary Receipts (ADRs). The shares surged 14% from the $149 offer price to open at $170, signaling robust appetite for AI-linked semiconductor assets even as a broader correction in chip stocks unfolds. With the offering oversubscribed more than seven times, the debut underscores the power of the AI narrative—and the premium U.S. investors are willing to pay for pure-play exposure to the memory technology powering everything from Nvidia GPUs to cloud data centers.

The shares surged 14% from the $149 offer price to open at $170, signaling robust appetite for AI-linked semiconductor assets even as a broader correction in chip stocks unfolds.

The timing is significant. Just two weeks before the ADR launch, SK Hynix’s domestic shares peaked at a record high, capping a meteoric run that saw the stock gain roughly 630% over the previous year. Yet the stock subsequently fell about 25% from that peak, reflecting a sector-wide pullback as investors questioned stretched valuations and the sustainability of AI hardware spending. The Nasdaq debut, therefore, acts as a critical test of sentiment: can the AI memory theme command fresh capital even after a steep decline? The 14% first-day pop and the oversubscribed order book suggest that at least for now, institutional and retail investors believe the rally has more room to run, viewing the recent weakness as a breathing spell rather than a cyclical peak.

At the core of the enthusiasm is SK Hynix’s dominant position in HBM, a specialized DRAM architecture that stacks memory dies vertically to deliver exceptionally high bandwidth while consuming less power—a critical requirement for training and running large language models and other AI workloads. The company supplies the vast majority of HBM3E chips used in Nvidia’s H100 and forthcoming Blackwell processors, as well as AMD’s Instinct GPUs. As cloud providers and enterprises race to build AI infrastructure, the world’s hunger for HBM has intensified, with SK Hynix and rival Samsung scrambling to add capacity. The $26.5 billion in proceeds, according to the company, will directly fund new manufacturing facilities, allowing it to expand output and maintain its lead against competitors.

From a capital markets perspective, the scale of the offering is staggering. At $26.5 billion, it trails only SpaceX’s record-breaking IPO from the previous month, putting the spotlight on the Nasdaq exchange’s ability to attract marquee international issuers. By choosing a U.S. listing rather than a secondary offering solely in Seoul, SK Hynix gains direct access to the world’s deepest pool of institutional investors, who have shown a willingness to pay higher multiples for AI-related names compared to Asian markets. The ADRs were priced at a 2.7% premium to the average share price in Seoul over the prior three trading days, effectively setting a floor for U.S. valuations above the home-market price—a structure that worked in the company’s favor on day one.

Sentiment experts were divided on the message. Thomas Hayes, chairman of Great Hill Capital, cautioned that “global semiconductors is the most crowded trade in the world right now,” suggesting that SK Hynix and its bankers are capitalizing on rich valuations while the window remains open. On the other hand, Dan Coatsworth, head of markets at AJ Bell, interpreted the strong demand as a sign that “the memory chip rally might have just taken a breath rather than peaked.” Both views contain an element of truth: the offering certainly is opportunistic, but the fact that it was more than seven times oversubscribed indicates genuine underlying demand rather than mere artificial pump.
