South Korean memory chipmaker SK Hynix is set to make history with its Nasdaq debut on Friday, July 10, after demand for its American Depositary Receipts exceeded available shares by more than seven times, according to reports. The $28-29 billion offering, potentially the largest ADR deal ever, underscores the intense appetite among U.S. institutional investors for direct exposure to the world’s second-largest manufacturer of High Bandwidth Memory chips, a critical component in artificial intelligence infrastructure.
SK Hynix shares surged 5.3% in Korean trading on Thursday to close at 2,186,000 won as news of the oversubscription spread through Asian markets. The rally extends a remarkable run that has seen the stock more than double since the first report of the company’s U.S. listing plans in late March. The strong demand for the ADR offering prompted underwriters to close the bookbuilding process early on Wednesday, July 8, U.S. time, two days ahead of the originally scheduled close, after orders covered the available allocation multiple times over.
The offering’s impact extended beyond equity markets, with dollar-selling linked to the share sale pushing the Korean won to a one-month high in the forwards market. Final pricing is scheduled for Thursday, July 9, with the ADRs expected to trade under the ticker SKHY on a when-issued basis before transitioning to regular trading. Each ADR will represent one-tenth of an ordinary share listed on the Korea Stock Exchange.
The Listing
SK Hynix plans to raise between 45.45 trillion won and $29.4 billion through the U.S. listing, making it one of the largest global equity offerings on record and surpassing Alibaba’s landmark 2014 ADR debut. The company intends to deploy the proceeds toward production facility purchases and capacity expansion for AI-related memory products, particularly advanced HBM and DRAM technologies that power the data centres underpinning generative AI applications.
The decision to list on Nasdaq rather than the New York Stock Exchange reflects a strategic choice to align with the tech-heavy, AI-focused investor base concentrated on that exchange. SK Hynix supplies HBM chips to most major AI accelerator manufacturers and has positioned itself as a pure-play beneficiary of the artificial intelligence infrastructure buildout. The company’s HBM business has grown rapidly as hyperscalers and cloud providers race to deploy next-generation AI training and inference systems.

The oversubscription level, more than seven times the available shares, signals that institutional demand has far outstripped supply, a dynamic that typically provides near-term price support following a listing as under-allocated investors turn to the open market. The book includes a mix of long-only funds, hedge funds, and specialist technology investors seeking exposure to the AI memory market without the broader cyclical exposure inherent in diversified semiconductor manufacturers.
GraniteShares has already filed for leveraged long and short exchange-traded funds tied to SK Hynix’s U.S. listing, with tickers SKUU and SKDD expected to launch on Monday, July 13, 2026, he first trading day after SKHY’s anticipated debut. The creation of targeted leveraged products before regular trading begins indicates expectations of high liquidity and sustained retail interest in the name.
Is There a ‘Korea Discount’?
The U.S. listing represents a deliberate effort by SK Hynix to narrow what analysts have long termed the “Korea discount”, the valuation gap between Korean-listed technology companies and their U.S. peers. By establishing a direct U.S. listing, the company aims to be valued alongside American semiconductor manufacturers such as Micron Technology rather than solely within Korea’s market structure, which has historically assigned lower multiples to memory chipmakers due to cyclical concerns and lower liquidity.
The timing of the offering, coming just weeks after SpaceX’s blockbuster flotation, has fuelled discussion about a broader AI-related capital-raising boom. SK Hynix’s ADR sale could “rewrite” the ADR trade, representing the second-largest share sale on record after SpaceX and the largest ADR-specific offering in history. The sequential mega-deals underscore sustained institutional appetite for AI infrastructure assets despite recent technology sector volatility and ongoing geopolitical tensions.
SK Hynix’s HBM leadership has been a key selling point for the offering. The company has secured long-term supply agreements with leading AI chip designers and has invested heavily in next-generation HBM4 technology to maintain its competitive edge against Samsung Electronics and Micron. The capital raised through the U.S. listing will enable SK Hynix to lock in multi-year capacity expansions at a time when lead times for advanced memory production equipment have extended significantly.
We will find out soon enough if there was really any truth to a Korea discount baked in. That is of course once the initial excitement of the SKHY listing tapers down.
What To Watch
The successful pricing and strong oversubscription of SK Hynix’s U.S. listing validate the company’s strategic positioning as a core AI infrastructure provider and suggest that institutional investors view HBM exposure as a multi-year growth opportunity rather than a short-term thematic trade. The listing should broaden the company’s investor base to include specialist AI, semiconductor, and growth funds that may have mandates or benchmarks tied to U.S. exchanges, potentially creating ongoing passive inflows beyond the initial deal.
Index and ETF inclusion represents another medium-term catalyst. A large free float and U.S. listing increase the odds of inclusion in major U.S. and global technology and semiconductor indices, which would generate additional systematic demand.
The company’s valuation trajectory in the first weeks of trading will provide important signals about whether U.S. markets are willing to assign a premium multiple to SK Hynix relative to its Korean listing and how it compares to American memory peers.
What is not in doubt it that irrespective of listing location, SK Hynix stock has been one of the huge stories of the past year, adding 677% on the period, despite sitting 25% down from recent highs. Buckle up, another memory superstar stock is coming to America.
