The ADRs opened well above their offering price of $149 each, climbing as much as 15 percent to trade above $170 during the first session. That surge pushed SK Hynix’s total market capitalization above $1.25 trillion. The stock is currently listed under the ticker SKHYV and is set to switch to its permanent ticker, SKHY, this week. Executives including SK Group chairman Chey Tae-won and SK Hynix chief executive Kwak Noh-jung rang the opening bell at the Nasdaq MarketSite in New York to mark the occasion.
The listing caps a remarkable run for a company that had, until now, traded almost exclusively in Seoul. SK Hynix shares have risen sharply this year as demand for high bandwidth memory, the specialized chip technology that feeds AI data centers, has outpaced supply. The company holds roughly 60 percent of the global HBM market and is closely tied to Nvidia’s supply chain through a joint development relationship. Its first quarter net profit jumped nearly 400 percent from a year earlier, with an operating margin above 70 percent, according to company results reported earlier this year.
Before this week, Micron Technology was the only pure memory chip stock available to U.S. investors. SK Hynix’s arrival gives American and European fund managers a second direct way to bet on the AI hardware buildout, and analysts say it should help close what traders have long called the “Korea discount,” the tendency of Korean-listed shares to trade below the valuations given to comparable U.S. companies. In a regulatory filing, SK Hynix said it expects the ADR listing to expand its investor base and allow its value to be assessed more fairly by global markets.
The company plans to use most of the proceeds for capacity expansion tied directly to AI memory production. That includes construction of the first phase of the Yongin Semiconductor Cluster, a new wafer fabrication site, along with the Cheongju plant used for advanced chip packaging, and new extreme ultraviolet lithography equipment purchased from the Dutch supplier ASML. Those machines are among the most expensive pieces of equipment in chipmaking, with individual units costing well into nine figures.
Demand for the offering was heavy. Bankers said the deal was oversubscribed more than seven times over, with commitments from major asset managers including Baillie Gifford and Coatue Management. Combined interest from anchor investors alone reportedly approached $7 billion. Because the shares sold represent a small slice of SK Hynix’s overall market value, less than 3 percent by some estimates, the limited float likely contributed to the sharp first day price jump.
The offering ranks as the second largest stock sale in U.S. history, behind only SpaceX’s roughly $75 billion capital raise a month earlier. It arrives at a moment when investors are still trying to work out how much of the AI infrastructure spending boom is durable and how much carries risk. That tension showed up elsewhere in markets this week too. S&P Global Ratings downgraded Oracle’s credit rating in the spring, citing heavy capital spending commitments and exposure to OpenAI as a major customer, a reminder that not every company tied to the AI buildout is viewed the same way by credit markets.
Investment managers who track the sector have pointed to a broader supply and demand imbalance behind the rally. Tim Garratt of Baillie Gifford told CNBC that SK Hynix remains well positioned because AI computing needs have outrun global memory capacity, leaving the company sitting at the center of a persistent supply pinch point. Nasdaq president Nelson Griggs made a similar point at an industry summit earlier in the week, noting that with only a handful of major competitors in advanced memory, tremendous product demand tends to translate directly into tremendous demand for the stock itself.
For SK Hynix, the next test comes quickly. The company is scheduled to report second quarter earnings on July 29, just under three weeks after its Nasdaq debut. Investors will be watching whether the ADR price holds its premium over the dollar value of the Korea-listed shares, a signal of whether U.S. listing genuinely unlocked new demand, and whether the earnings report confirms that the HBM shortage driving the stock’s rally still has room to run. Counterpoint Research director MS Hwang has described SK Hynix as the top player in HBM on both product quality and manufacturing cost, a position the company will now need to defend in full view of Wall Street.
