The massive upcoming US listing of South Korean memory chip giant SK hynix Inc. is generating intense investor demand, receiving over seven times the subscription for its American Depositary Receipts (ADRs) and further fueling the "silicon-based inflation" narrative, according to media reports citing informed sources.

Insiders indicate the offering of 177.9 million ADRs has attracted significant interest from institutional investors, including global long-only funds, technology-focused hedge funds, major sovereign wealth funds, and top Wall Street investment firms specializing in Asian markets.

Based on SK hynix's closing share price of 2.076 million won ($1,380) on the Seoul exchange on Wednesday, the US offering is expected to raise approximately $24.5 billion, according to the latest institutional calculations. This is lower than the initially planned $29.4 billion.

It is important to note that the total number of ADRs being issued remains unchanged. The downward revision in fundraising is purely due to share price movement and does not signal any reduction in the company's financing appetite.

At this scale, the offering would rank among the largest US ADR debuts by a foreign company, second only to the roughly $25 billion debut by Chinese e-commerce leader Alibaba, based on compiled data.

SK hynix is actively seeking to raise substantial funds through a US listing to expand its memory chip production capacity, capitalizing on robust global investor demand for shares of the high-flying and supply-constrained memory chip giants.

The influx of capital into SK hynix's US listing plan, coupled with the exceptionally strong results and outlook recently reported by US memory chip leader Micron, underscores that the memory chip super-cycle is far from over.

The combination of SK hynix's planned $29.4 billion US fundraising and Micron's stellar "earnings plus guidance" significantly reinforces a firm market optimism: the so-called "memory super-cycle" is not only ongoing but has evolved from a traditional PC/smartphone cycle into a structurally scarce super-cycle driven by AI data centers.

While Micron validates the genuine strength of demand, SK hynix validates the intense capital enthusiasm, highlighting global investors' continued willingness to pay a high premium for "memory chip supply bottlenecks."

Insiders note that discussions are ongoing and details of the US listing may change. A spokesperson for SK hynix declined to comment.

The ADR offering comes as shares of SK hynix in South Korea and competitors like Micron in the US have fallen sharply in recent days, partly due to a cooling of the fervent sentiment around AI infrastructure bets amid extremely crowded and highly leveraged bullish positions in the Korean market.

SK hynix shares fell 5.7% in South Korea on Wednesday and are now down 30% from the record closing high in late June, though they remain roughly triple their price at the start of the year.

The Wall Street investment banks leading the ADR offering were expected to stop accepting orders at 4 p.m. local time on Wednesday. The offering is led by Bank of America, Citigroup, Goldman Sachs, and JPMorgan, with nine other institutions also participating.

SK hynix has secured strong subscription interest from top global investment firms including Baillie Gifford, Coatue Management, and Situational Awareness Partners, for up to $7 billion worth of the ADRs being offered.

The company and its long-time rival Samsung Electronics are preparing to increase investments in their home country under a government-led initiative worth up to $880 billion, focusing on AI data center construction and memory chip capacity expansion.

These ADRs are scheduled to begin pre-market trading on the Nasdaq Global Select Market on Friday under the symbol "SKHYV." When regular trading begins on July 13, the ticker will change to "SKHY."

Key Drivers of the Capital Influx

SK hynix is the core supplier of High-Bandwidth Memory systems to AI chip leaders like Nvidia. This US listing plan marks a milestone in the company's remarkable ascent.

After becoming the preferred HBM supplier for Nvidia, the dominant force in AI chips, SK hynix has become the world's largest supplier by market share in HBM systems. This has allowed it to surpass its long-time South Korean rival Samsung Electronics in market capitalization and overall DRAM share at times.

Massive AI compute clusters, whether from Google's TPUs or Nvidia's GPUs, rely on fully integrated HBM memory systems. Additionally, tech giants accelerating the construction or expansion of AI data centers must purchase server-grade DDR5 memory and enterprise-class high-performance SSDs/HDDs on a large scale.

Samsung Electronics, SK hynix, and Micron are positioned at the core of these three critical memory areas: HBM, server-grade high-performance DRAM, and high-end data center SSDs, making them direct beneficiaries of the AI infrastructure wave.

The unparalleled preliminary Q2 results recently disclosed by Samsung Electronics serve as the most direct profit sample of this memory chip super-cycle. Operating profit for April to June is estimated to have surged approximately 19-fold year-over-year to 89.4 trillion won (about $58.4 billion), setting a new quarterly record and representing a 56% increase from the previous quarter's strong base.

Revenue for the period is expected to reach 171 trillion won, exceeding market estimates of 169.2 trillion won and representing a year-over-year increase of about 129%. The company plans to release full financial results on July 30.

Samsung's quarterly operating profit has exceeded Nvidia's last quarterly operating profit of $53.5 billion, making it the company with the highest quarterly operating profit globally.

Statistics and forecasts compiled by TrendForce reveal the structural strength of the memory chip price surge driven by the AI infrastructure boom. They project significant sequential price increases for both DRAM and NAND Flash through 2026, with suppliers continuing to shift capacity towards AI server-related compute clusters and enterprise SSD demand for data center construction.

The grand investment narrative of "seeking silicon-based inflation, weakening carbon-based" this year essentially represents capital shifting from traditional "carbon-based assets" reliant on population, resources, and linear economic growth—such as manufacturing, autos, consumption, real estate, and energy—towards high-end manufacturing chains centered on silicon wafers related to AI computing infrastructure.

This is not merely a chase for tech stocks; it is a global repricing of the "core carrier of future growth." Entities controlling AI computing infrastructure resources for training and inference command higher valuation premiums, as capital allocation weight shifts from old-economy assets dependent on population, oil & gas, real estate, and consumption cycles towards infrastructure assets capable of supporting AI training/inference and the expansion of automated physical AI productivity.

The core logic behind the global embrace of "silicon-based inflation" lies in the fact that the scarcest resources in the AI era are not traditional labor, real estate, or general production/manufacturing capacity, but rather "silicon-based means of production" like GPUs/ASICs, HBM/DRAM/NAND memory chips, data center CPU components, high-performance Ethernet infrastructure, advanced packaging capacity, cutting-edge semiconductor manufacturing equipment like EUV, data center power chains, and data center optical interconnects/communications.

UBS Bets on SK hynix ADR Premium: A Potential Arbitrage Window

The US ADR offering follows a staggering approximately 850% surge in SK hynix's share price on the Seoul market over the past 12 months, which propelled its market capitalization above $1 trillion, briefly surpassing that of Samsung Electronics.

As SK hynix's ADRs prepare to trade publicly in the US, UBS stated in a report on Tuesday that investors should buy the planned US ADRs and actively sell the company's shares traded on the South Korean stock market, as the newly issued securities may trade at a premium.

UBS's sales and trading department noted in a client report that compared to the Korean stock market, SK hynix US ADRs might be more attractive to institutional investors like hedge funds because holding these securities would be more efficient and cost-effective.

Furthermore, even as memory chip leaders and the AI semiconductor sector have recently entered a significant downward correction, Wall Street giants remain bullish on the long-term trajectory of the "memory super-cycle" and AI-related semiconductor stocks amid the unprecedented AI infrastructure boom.

On Wall Street, analysts are collectively optimistic about further significant gains for the three major memory chip manufacturers—SK hynix, Samsung Electronics, and Micron. The core logic is that under the backdrop of the fervent global AI data center construction boom, demand for HBM, high-capacity DRAM, and enterprise NAND memory chips continues to explode, driven by relentless AI computing infrastructure needs.

The UBS report stated, "Investors will focus on the potential foreign investment quota space that may become available as SK hynix transitions future lines from local Korean listing to US secondary ADR listing." It added that without this quota flexibility, inefficient and insufficient investment channels could lead the US trading line to trade at a significant and sustained premium.

When ADRs are not fully fungible, US-listed ADRs often trade at a premium compared to their locally listed shares abroad. Compiled data shows that the US ADRs of "chip foundry king" TSMC have recently traded at an average premium of up to 16% compared to its shares traded in Taiwan.
