SK Hynix Nets $26.5 Billion in Historic Nasdaq Debut as AI Memory Demand Fuels Capacity Splurge

The South Korean memory-chip titan SK Hynix has pulled off the largest US initial public offering by a foreign company on record, raising roughly $26.5 billion through a listing of American Depositary Receipts on the Nasdaq. By comparison, only SpaceX has closed a bigger capital round globally in recent years. The scale of demand was staggering: the order book was more than seven times oversubscribed, with over 500 institutional investors submitting bids worth a combined $200 billion.

Priced at $149 per ADR, representing one-tenth of an ordinary Seoul-listed share, the offering commanded a premium of roughly 3% above the stock's prior closing price in South Korea. While the conditional trade kicked off Friday under the ticker SKHYV, regular trading under the symbol SKHY is scheduled to begin on July 13. Chairman Chey Tae-won and CEO Kwak Noh-jung personally rang the opening bell at the Nasdaq, underscoring the company’s ambition to boost its international profile.

Capital Deployment Targets HBM Production

The bulk of the proceeds is earmarked for expanding capacity for High Bandwidth Memory (HBM), the chips that have become the backbone of artificial intelligence infrastructure. SK Hynix, which commands a market-leading 56.4% share of the HBM market, plans to channel the fresh cash into three major projects. The largest chunk — about 31 trillion won — goes to the first phase of the Yongin chipmaking cluster. Another 19 trillion won will fund the P&T7 packaging facility in Cheongju, while 11.9 trillion won is set aside for purchasing advanced EUV lithography scanners. Management has set a target of achieving net cash of 100 trillion won as it executes these investments.

Should investors sell immediately? Or is it worth buying SK Hynix?

The timing appears strategic: the explosive growth of AI data centers has created a voracious appetite for memory chips, and industry watchers warn that supply constraints could persist until 2030 given the multi-year construction timelines for new fabs. For SK Hynix, the Nasdaq venue also opens the door to passive fund flows. Market participants expect the stock to be added to the Philadelphia Semiconductor Index soon, a move that would funnel billions of dollars in passive investment into the ADRs.

Closing the Korea Discount

Despite the record haul, SK Hynix still trades at a valuation discount of 20% to 40% relative to US rival Micron Technology on a price-to-earnings basis. That gap, often referred to as the Korea discount, stems in part from limited access for US institutional investors. Analyst Dave Mazza noted that the Nasdaq listing eliminates that access barrier, while Steve Sosnick of Interactive Brokers predicted the new ticker would attract momentum-driven traders looking for exposure to the AI chip theme.

The stock’s journey in Seoul has been anything but smooth. As of the latest session, shares stood at 2,196,000 won, up 0.46% from the prior close, but still 26.48% below the June record of 2,987,000 won. The year-to-date gain remains a blistering 224.37%, and the 52-week low of 491,500 won from October 2025 leaves the stock trading 346.80% above that trough. Annualized volatility of 114.70% underscores the hair-raising swings that have accompanied the rally.

The first real test for SK Hynix now begins under the glare of US markets. With a market capitalization equivalent to roughly €855.89 billion and the semiconductor industry’s notorious cyclicality hanging overhead, investors will be watching closely to see whether the New York listing can permanently shrink the valuation gap — or whether the stock’s wild ride continues on both sides of the Pacific.
