From HBM Leader to Nasdaq Newcomer: How SK hynix’s US Listing Could Reshape Global Memory Chip Valuation Logic

On July 9, 2026, the global memory chip market reached a critical turning point. SK hynix’s initial public offering in the United States was oversubscribed by more than seven times, with an offering size of approximately $24.5 billion, and it is set to officially list on Nasdaq on July 10. On that very day, South Korea’s KOSPI index opened up more than 3%, SK hynix’s stock price rose more than 8% at one point in early trading, Samsung Electronics gained more than 4%, and Japan’s Kioxia surged more than 10%. Earlier, over the previous several trading days, this same group of stocks had just undergone a dramatic pullback, with market value evaporating by more than $260 billion within nine days.

The “Seven Titans of Storage”—SK hynix, Samsung Electronics, Micron Technology, Kioxia, Western Digital, SanDisk, and YMTC—have shown nearly synchronized crash-and-rally moves over the past week. Behind this collective abnormal movement is a deep game between the AI memory supercycle and the repricing logic of the capital markets. And the fuse that ignited this battle is precisely SK hynix’s U.S. listing, which is about to be completed.

A capital operation rewriting IPO history

SK hynix’s U.S. listing is so large in scale and so fast in timing that there is almost no precedent in the history of the semiconductor industry.

According to filings with the U.S. Securities and Exchange Commission, SK hynix plans to issue 17.79 million American Depositary Shares (ADS), with each ADR representing one-tenth of a common share. Based on the company’s South Korea-listed stock’s Wednesday closing price of 2.076 million won per share (about $1,380), the financing size of this U.S. IPO is approximately $24.5 billion. Based on calculations using Bloomberg data, this would make SK hynix the second-largest transaction in the history of foreign companies listing in the U.S., behind only Alibaba’s 2014 record of $25 billion. If ranked by global IPO history, it places third globally after SpaceX’s $85.7 billion and Saudi Aramco’s $25.6 billion.

The enthusiasm at the subscription side is even more astonishing. As Bloomberg cited informed sources, the subscription multiple for SK hynix’s ADR has already exceeded seven times. Subscription demand came from multiple types of institutions, including global long-term funds, technology-sector special funds, sovereign wealth funds, and Asia-themed global investors. Among them, Baillie Gifford, Coatue Management, and Situational Awareness Partners have expressed combined subscription intentions totaling as much as $7 billion.

The underwriting lineup is arguably top-tier—led jointly by Goldman Sachs, JPMorgan Chase, Bank of America, and Citigroup, the four major international investment banks. SK Group Chairman Chey Tae-won will personally travel to New York to attend the Nasdaq bell-ringing ceremony on July 10. After the listing, SK hynix is expected to be included in the Nasdaq 100 Index, attracting continued inflows of passive capital.

The destination of the raised funds is equally clear: all will be invested in the expansion of advanced memory chip production capacity and the procurement of core equipment, including the construction of the first phase of the Yongin semiconductor wafer cluster in South Korea, the expansion of the seventh-generation advanced packaging production line in Cheongju, and bulk purchases of high-end manufacturing equipment such as ASML’s EUV (extreme ultraviolet) lithography machines.

Nine days of $260 billion evaporates and an 8% rebound in one day

However, in sharp contrast to the oversubscription of the IPO, SK hynix’s domestic stock price in South Korea has experienced violent fluctuations over the past two weeks.

On July 7, SK hynix fell from nearly 3 million won per share to 2.1 million won per share within nine trading days, erasing more than $260 billion (equivalent to more than 1.76 trillion yuan). On July 8, SK hynix fell 5.7% in the South Korean market, and compared with the historical closing high set in late June, the cumulative pullback was about 30%. Samsung Electronics also faced similar selling pressure during the same period, with the KOSPI index once falling more than 8% intraday.

The direct triggering factor behind this concentrated sell-off was market concern that investment in AI infrastructure had become overheated. LSEG, the London Stock Exchange Group, showed in forecasts from 30 analysts that the story of Samsung repeatedly setting profit records for three consecutive quarters had been fully priced in, and the reason for capital leaving was “not that the numbers are bad enough.” Whether memory chip prices have already peaked, and whether AI capital expenditure can be sustained—these questions flared up in early July.

But on July 9, the market narrative quickly reversed. In the early Asia trading session, memory chip stocks rose collectively: SK hynix gained more than 8%, and its intraday high reached 2.227 million won; Samsung Electronics rose more than 4%; and Kioxia surged more than 10% at one point. In U.S. Eastern Time on July 8, the U.S. memory sector had already moved first to repair—Micron Technology closed up 1.11%, SanDisk closed up 6.77%, and Western Digital closed up 3.42%.

This “sharp drop–sharp rebound” rhythm precisely reflects the market’s pricing game ahead of SK hynix’s ADR listing. On one hand, some capital chose to take profits before the ADS/ADR listing and avoid the risk of cross-market price spreads. On the other hand, other capital viewed the pullback as an opportunity to reposition. Kim Dong-won, head of research at KB Securities, noted that with the ADR listing, global investors’ accessibility will expand, and it is expected that the U.S. ADR and the stock of the Korean parent company will be revalued simultaneously. He also specifically mentioned the precedent of TSMC’s ADR listing in 1997—once the global investor base expands, the ADR can trade at a premium to the parent stock, and persistent conversion-and-arbitrage demand using the price spread will continue.

The HBM battlefield: 58% market share and a triple supercycle

SK hynix’s ability to secure seven-times oversubscription and raise $24.5 billion is not primarily due to capital market mechanics itself, but rather due to its irreplaceability in the AI memory arena.

High Bandwidth Memory (HBM) is the most critical memory component in today’s AI computing infrastructure. In the first quarter of 2026, SK hynix ranked first in the global HBM market with a 58% market share. Samsung Electronics and Micron each accounted for 21%, tying for second. In the overall DRAM market, Samsung held the top spot with a 38% share, SK hynix ranked second with 29%, and Micron ranked third with 22%. In the NAND flash market, Samsung maintained the lead with a 29% share, while SK hynix ranked second with an 18% share.

In a report on July 7, UBS noted that SK hynix is continuously working to sign more revised long-term agreements, focusing on DDR5 and NAND Flash for hyperscale data center customers. The terms of these contracts exceed 5 years, and roughly 60% to 70% of the expected volume and pricing have already been locked in. UBS forecasts that HBM’s share of SK hynix’s DRAM revenue will rise from 15% in 2026 to 58% in 2030. The firm raised SK hynix’s target price from 3 million won to 3.2 million won and maintained a “Buy” rating. JiaoYin International is even more optimistic, raising its target price to 3.5 million won and pushing back its assessment of when the memory shortage will ease by two quarters to at least Q4 2027. KB Securities set a target price at 4.2 million won, expecting the memory chip shortage to persist through the end of 2028.

Nomura Securities predicts that the global memory market size will surge 98% year over year in 2026 to $445 billion, expanding further to $590 billion in 2027. Bank of America expects the global DRAM and NAND market size to reach $876.8 billion in 2026 and exceed $1.2 trillion in 2027. Institutional estimates show that in 2026, the global DRAM supply-demand gap is about 7%, the HBM gap is about 6%, and the NAND gap is about 5%, with the shortage situation continuing to intensify.

But the other side of the supercycle is regulatory risk. On July 6, a class-action lawsuit against Micron, Samsung, and SK hynix was accepted by the U.S. District Court for the Northern District of California, alleging that the three manufacturers have coordinated to compress DRAM supply since 2022 and switched to high-performance memory components such as HBM, resulting in conventional DRAM prices rising by about 700% over four years. These allegations are currently still the plaintiffs’ claims and have not been recognized by the court, but the lawsuit itself has already become a non-negligible variable affecting valuations in the memory sector.

The resonance logic between the crypto market and the storage sector

The sharp fluctuations in the memory chip sector are not completely unrelated to the crypto market’s trend.

On July 9, 2026, according to Gate data, Bitcoin was at $62,178, down 2.0% over the past 24 hours; Ethereum was at $1,740, down 2.0%. The total crypto market cap was about $2.15 trillion, and the Fear and Greed Index fell into the “Extreme Fear” range of 20-23. Over the past 24 hours, liquidations totaled $327 million, with longs accounting for 62%.

The core catalyst behind the crypto market’s pressure is the escalation of geopolitical risk—Trump announced at the Ankara summit that the U.S.-Iran ceasefire “has ended,” the U.S. military has launched multiple rounds of strikes on Iran, and WTI crude oil broke above $75 per barrel. Risk assets faced broad pressure, with BTC rapidly dropping from above $64,000 to the $61,500 area.

The linkage between memory chips and crypto assets is at least reflected in three layers:

First, the growth in demand for AI computing infrastructure directly drives demand for HBM, DRAM, and enterprise-grade NAND. AI data centers require large amounts of high-performance memory, and crypto mining and blockchain infrastructure also rely on chip supply. When memory chip capacity is heavily occupied by HBM at scale, supply in other areas is inevitably squeezed.

Second, the sustained rise in memory chip prices could become a source of inflationary pressure. Binance Research previously pointed out that supply-demand imbalances in storage semiconductors intensified by AI could become a new inflationary pressure, thereby affecting expectations for macro monetary policy and indirectly pressuring risk assets (including cryptocurrencies).

Third, from the perspective of capital flows, the sharp fluctuations in the storage sector may affect the risk appetite of some cross-asset allocation funds. When semiconductor stocks experience a 30% correction in the short term, some investors’ risk-aversion sentiment may spread to crypto assets. Conversely, when storage stocks rebound strongly, the repair of risk appetite may provide some support to the crypto market.

Analyst Jukan at Critini noted that strong HBM demand helps support memory chip prices, and sustained stability in chip prices may benefit some altcoins. While this correlation is not one-to-one, there is indeed a transmission chain at the macro level.

Three observation dimensions after the listing

After SK hynix officially lists on Nasdaq on July 10, the market will enter a new round of the game. The following dimensions are worth ongoing attention:

Cross-market price spreads and arbitrage mechanisms. The spread between the ADR and the Korean parent company’s stock will directly determine where arbitrage capital flows. If the ADR trades at a premium, it may attract capital moving from the Korean market to the ADR; conversely, it may trigger reverse arbitrage. Such cross-market capital flows will, in the short term, amplify volatility in SK hynix’s stock price.

Quarterly trends in memory chip prices. UBS forecasts that the average selling price of DRAM will rise 43% quarter over quarter in Q2 2026, 21% in Q3, and 13% in Q4. Whether these forecasts can be realized will directly determine profit expectations for the memory sector. The real test will be the Q2 2026 earnings season—if hyperscale cloud vendors maintain or raise their capital expenditure guidance, it will be a positive signal for memory stocks.

Litigation progress and regulatory direction. Although the class-action lawsuit against the three major memory manufacturers is still at an early stage, its direction could affect the market’s valuation logic for the entire industry. If the lawsuit pushes regulators to intervene in DRAM pricing mechanisms, it could have far-reaching effects on the competitive landscape.

The collective abnormal movement of the Seven Titans of Storage is, in essence, a projection of the AI memory supercycle onto the capital markets. SK hynix’s U.S. listing is both a confirmation of this cycle and the starting point for a new round of pricing games. Seven-times oversubscription and a fundraising size of $24.5 billion prove global capital’s long-term confidence in the AI memory track; meanwhile, the $260 billion market value evaporation over nine days reminds the market that supercycles are never short on volatility.

For investors in the crypto industry, the trend in the memory chip sector provides an important window to observe how global technology assets are priced and how risk appetite evolves. When the HBM leader moves from South Korea to Nasdaq, and when memory chips are redefined from “commodities” into “AI infrastructure,” this capital migration across the Pacific is rewriting not only the valuation of one company, but also the pricing logic of the entire technology supply chain.

FAQ

Q: What is the exact fundraising size of SK hynix’s U.S. listing?

According to Bloomberg data, based on SK hynix’s July 8 South Korea closing price of 2.076 million won per share, the financing size of this U.S. IPO is approximately $24.5 billion. This figure is only behind Alibaba’s $25 billion in 2014, making it the second-largest transaction in the history of foreign companies listing in the U.S. Previously, market rumors put the scale at $29 billion, but it has been adjusted downward recently due to the overall pullback in South Korea’s semiconductor sector.

Q: What impact will SK hynix’s ADR listing have on the stock price of its Korean parent company?

Kim Dong-won, head of research at KB Securities, stated that with the ADR listing, global investors’ accessibility will expand, and the U.S. ADR and the Korean parent company’s stock prices are expected to be revalued in sync. Citing the precedent of TSMC’s ADR listing in 1997, based on the expansion of the global investor base, the ADR may form a premium over the parent company’s stock, and conversion-and-arbitrage demand using the price spread will continue.

Q: Has the memory chip supercycle already peaked?

Many institutions believe the supercycle has not yet peaked. UBS predicts there is further upside potential in the contract pricing for DDR and NAND Flash in the second half of 2026. JiaoYin International has pushed back the timeframe for the memory shortage to ease to at least Q4 2027. KB Securities expects the shortage to persist through the end of 2028. However, the market does have concerns about overheated AI infrastructure investment, which is the direct reason for the recent stock price pullback.

Q: What is the connection between the memory chip sector and the cryptocurrency market?

The connection is mainly reflected in three aspects: rising demand for AI computing infrastructure drives memory chip demand, indirectly affecting the chip supply pattern; rising memory chip prices could become a source of inflationary pressure, influencing expectations for macro policy; and sharp fluctuations in the memory sector could affect the risk appetite of cross-asset investors, which then feeds into the crypto market. However, this linkage is indirect and not one-to-one.

Q: What fields will the fundraising from SK hynix be invested in?

The raised funds will be fully allocated to expanding advanced memory chip production capacity and purchasing core equipment. This mainly includes the construction of the first phase of the Yongin semiconductor wafer cluster in South Korea, the expansion of the seventh-generation advanced packaging production line in Cheongju, and the bulk procurement of high-end manufacturing equipment such as ASML’s EUV extreme ultraviolet lithography machines. The core direction is to expand currently highly constrained HBM production capacity.
