SK Hynix’s Record $26.5 Billion Nasdaq Debut: The Largest ADR Listing in History

SK Hynix, the South Korean memory-chip giant and a key Nvidia supplier, made history on July 10, 2026, by completing the largest American Depositary Receipt (ADR) listing ever on the Nasdaq. The company raised approximately $26.5 billion, pricing 177.9 million ADRs at $149 each—a deal that surpassed Alibaba’s $25 billion U.S. debut in 2014 and ranks as the second-largest IPO of any kind in U.S. history . But the record-setting offering landed against a backdrop of declining AI-sector sentiment, with its Korea-listed shares having dropped nearly 30% from all-time highs in the preceding month . That tension—between intense institutional demand and mounting analyst caution—made the listing a closely watched test of whether the AI semiconductor boom had reached its peak .

Ticker and listing structure

SK Hynix ADRs began trading on the Nasdaq Global Select Market on Friday, July 10, 2026, under the ticker symbol SKHY . Initially, the stock traded on a when-issued basis under the ticker SKHYV before converting to the permanent SKHY symbol . Each ADR represents one-tenth of one common share of SK Hynix (10 ADRs equal 1 common share listed on the Korea Exchange) . The company’s ordinary shares continue to trade on the Korea Exchange under ticker 000660.KS .

Offering size and pricing

The final public offering price was set at $149 per ADR, which was approximately 2.9% above the converted value of its Korean-listed shares based on the prior day's closing price in Seoul . The company issued 177.9 million ADRs, raising roughly $26.5 billion .

Initial targets had been as high as $29.4 billion to $29.65 billion when SK Hynix filed its registration statement in late June 2026 . Early indicative prices had been around $166 per ADR . The final $26.5 billion total, while below the top of the range, still set a new record for a foreign issuer’s U.S. listing, exceeding the $25 billion Alibaba raised in its 2014 New York IPO .

Market reception and oversubscription

Institutional demand was exceptionally strong. The offering was more than seven times oversubscribed, with Reuters reporting that the deal was heavily oversubscribed ahead of pricing . Bloomberg also noted that demand had already exceeded the number of ADRs available before the final price was set .

However, the listing came at a delicate moment for AI-related stocks. SK Hynix’s Korea-listed shares had surged roughly 770% over the prior 12 months and had more than tripled in 2026 alone, but then fell by nearly 30% from their June record highs in the month leading up to the Nasdaq debut . The company’s stock experienced a steep single-day drop of almost 15% in late June, followed by a rebound, reflecting the volatile mood around AI memory stocks .

The earliest available price data shows a July 9 close of $158.14 for the ADR on certain data services, though this is a preliminary figure and does not represent a full trading day’s close on the Nasdaq . No official first-day closing price from Nasdaq was available in the sources at the time of writing.

Why SK Hynix listed on the Nasdaq: Use of proceeds

SK Hynix’s stated reason for the dual listing was to tap deeper U.S. capital markets to fund growth in its most critical product line: high-bandwidth memory (HBM) chips, which are essential for Nvidia’s AI accelerators . The proceeds will be directed toward HBM capacity expansion and R&D . The company also aims to close the valuation gap with U.S. peers such as Micron Technology, which trade at higher multiples than Korean-listed memory stocks, and to reduce its reliance on the Korea Exchange for future capital needs .

Analyst cautions about AI-driven enthusiasm

The record-setting listing was widely framed as a “stress test” for the sustainability of the AI semiconductor super cycle . Several analysts and commentators warned that investor expectations had become dangerously high.

• Zachary Hill, head of portfolio management at Horizon Investments, said the listing would test whether AI momentum could sustain its highs, adding: “We are in a correction phase following the explosive rise of AI infrastructure, semiconductor, and memory companies. Expectations have become so inflated that it’s practically impossible to surpass them” .
• Jim Cramer cautioned that the huge IPO pipeline—and SK Hynix’s $28 billion deal in particular—could overwhelm the market, saying “we have to be careful” and noting that “a bull market can also be killed by excess supply” .
• Morningstar and Fortune characterized the debut as a key indicator of whether AI stock euphoria had peaked, pointing out that SK Hynix shares had surged nearly 2,000% over three years . A Fortune headline captured the stakes: the listing “could signal if the market can still boom—or is headed for a bust” .
• Analysts also flagged risks of memory industry supply gluts and volatility, given the sector’s well-known boom-and-bust cycles .

Key uncertainty

No single authoritative source has yet published a final official first-day closing price for SKHY as of the end of July 10 U.S. trading. The $158.14 figure from Investing.com Canada is the strongest available data point but should be treated as preliminary pending an official Nasdaq close report .
