$SKHYNIX ‌

The High-Bandwidth Memory (HBM) industry is experiencing one of the biggest contradictions in semiconductor history. Demand has reached record levels, yet one of the sector's strongest companies is seeing its stock collapse.

SK Hynix has already sold out its entire HBM production capacity for 2026. CEO Kwak Noh-jung told Reuters on July 10 that 2027 is expected to experience the worst memory shortage the industry has ever seen, with demand projected to remain ahead of supply well beyond 2030.

Despite this exceptionally strong outlook, SK Hynix's American Depositary Receipts closed at $143.02 on July 28, falling below the $149 IPO price established only 19 days earlier during the company's record $26.5 billion U.S. listing. This dramatic disconnect reflects a broader reassessment of semiconductor valuations rather than weakening demand.

DEMAND CONTINUES TO BREAK RECORDS

The HBM market continues expanding at an extraordinary pace.

Industry projections from Futurum Equities estimate the global HBM market will grow from approximately $65 billion in 2026 to $120 billion in 2027, eventually approaching $290 billion by 2030.

Nvidia's product roadmap illustrates why memory demand continues accelerating. Memory capacity has increased from 80 GB of HBM2E on the A100 platform to an expected 1,024 GB of HBM4E on Rubin Ultra. Every new GPU generation requires larger HBM stacks, greater bandwidth, and increasingly sophisticated packaging technologies.

SK Hynix remains one of the biggest beneficiaries, supplying Nvidia's most advanced AI chips. After gaining nearly 900% over the previous 24 months, the company briefly surpassed a $1 trillion market valuation while controlling roughly 69% of the HBM market during early 2025.

WHY SUPPLY CANNOT KEEP UP

Expanding HBM production is far more complex than increasing wafer output.

Manufacturing requires additional cleanroom capacity, advanced EUV lithography systems, cutting-edge packaging facilities, and highly specialized engineering talent. Every part of the production chain must expand simultaneously.

To address future demand, SK Hynix is enlarging operations in Icheon and Cheongju, while constructing a major semiconductor complex in Yongin. The company is also participating in South Korea's national strategy to double memory production capacity over five years through approximately 400 trillion won ($266 billion) in investment.

Funds raised through the IPO are dedicated primarily to HBM capacity expansion and additional EUV equipment. Even with these investments, management expects production capacity to remain below demand for several years.

Further highlighting supply constraints, Nvidia and SK Hynix announced a $500 billion preferential supply agreement during July 25–27 covering HBM3E and next-generation HBM4 products. The agreement effectively reserves future HBM4 production and reshapes long-term AI supply chain dynamics.

WHY THE STOCK IS DECLINING

Strong demand alone is no longer enough to support semiconductor valuations.

The first challenge involves HBM pricing. Although demand remains exceptionally strong, long-term supply agreements limit pricing flexibility. Korea Investment & Securities reduced its Q2 earnings forecast by 8% on July 13, explaining that fixed-price HBM contracts restrict average selling price growth even while conventional DRAM and NAND prices surged 30% and 50% quarter over quarter.

Goldman Sachs also downgraded SK Hynix to Neutral, projecting double-digit HBM average selling price declines during 2026 as industry production expands toward 485,000 wafers per month, with expected supply growth of 48% exceeding projected demand growth of 38%.

Meanwhile, Nvidia's transition from B300 to Rubin introduces only a modest increase in HBM content per GPU, reducing expectations for future demand acceleration.

AI INVESTMENT IS UNDER THE MICROSCOPE

Investor attention has shifted beyond semiconductor demand toward the sustainability of AI infrastructure spending itself.

Nvidia shares dropped below $200 on July 28 after reports suggested the company could provide $250 billion in financing guarantees supporting OpenAI's data center expansion. Investors questioned whether AI infrastructure growth is increasingly dependent on financial engineering rather than organic demand.

Additional announcements added to market concerns. Nvidia partnered with SK Telecom to develop a 2-gigawatt Korean data center, while Samsung signed a $200 billion memorandum of understanding with Broadcom covering HBM and foundry cooperation.

Combined, nearly $950 billion in AI-related agreements involving Korean companies prompted investors to reassess long-term funding sustainability across the entire AI ecosystem.

CHINA ADDS NEW COMPETITION

Competitive pressure intensified following the successful IPO of Chinese memory producer CXMT.

Its market debut revived fears of future DRAM oversupply after reports suggested Apple had urged the Trump administration to permit selected Chinese-made chips within certain products.

The reaction across South Korea was severe.

The KOSPI dropped as much as 9.19% to 6,134 points, triggering both circuit breakers and sidecar mechanisms.

SK Hynix declined 14.37% in Seoul to 1,555,000 won, while Samsung fell 9.5%.

Bloomberg also noted that SK Hynix's ADR falling below its IPO price resembled other high-profile listings, including SpaceX, that also traded below their offering prices shortly after listing.

FUNDAMENTALS REMAIN STRONG

Operational performance continues to impress despite market weakness.

Analysts project Q2 revenue of approximately 80.9 trillion won alongside operating profit near 60.4 trillion won, representing year-over-year increases of 264% and 556%, respectively.

Expected operating margins between 74.6% and 77% remain among the strongest within the global semiconductor industry.

However, investors are increasingly focused on future competition.

HBM4 mass production begins during Q3 2026 with pricing estimated 45–55% above HBM3E. At the same time, Samsung and Micron are entering the HBM4 market, reducing SK Hynix's pricing dominance.

Its market share has already declined from approximately 69% to around 56–58% by Q2 2026 as the market transitions from near-monopoly conditions toward a more balanced competitive environment.

THE NEXT MAJOR TEST

July 29 represents one of the most important dates for semiconductor investors.

SK Hynix will publish its first earnings report since the Nasdaq listing, while Microsoft, Meta, and the Federal Reserve all announce major updates the same day. Apple and Amazon will complete Big Tech earnings later in the week.

Markets will closely examine operating margins, HBM4 production schedules, and long-term pricing agreements.

Positive guidance could stabilize investor confidence, while further evidence of pricing pressure may extend the current correction.

MARKET IMPLICATIONS

The semiconductor industry is entering a new valuation phase where rapid demand growth alone no longer guarantees higher stock prices.

Investors now require proof that AI infrastructure spending generates durable profitability throughout the supply chain.

Recent examples reinforce this shift. Intel delivered 15% revenue growth, yet its shares still declined 7.9% after a $140 billion AI capital expenditure plan raised concerns over future cash flow.

Although SK Hynix continues producing operating margins exceeding 70%, its shares have still fallen roughly 33% from the June 25 peak within only three weeks.

CRYPTO CONNECTION

Technology and digital asset markets remain increasingly interconnected.

Bitcoin traded near $63,199 on July 28, declining 2.9% over 24 hours as semiconductor weakness spread across broader risk assets.

Projects linked to AI infrastructure, including FET, AKT, and RENDER, rely on the same investment cycle currently facing increased investor scrutiny.

Should semiconductor valuations continue resetting, AI-related crypto sectors could experience meaningful secondary effects.

FINAL OBSERVATION

The HBM industry demonstrates how extraordinary demand can coexist with declining equity valuations.

Production remains sold out. Supply shortages are expected to continue for years. Yet investors are shifting their focus toward pricing power, competition, financing quality, and long-term profitability rather than demand alone.

The coming weeks driven by SK Hynix earnings, major technology company results, and Federal Reserve decisions will determine whether the recent correction represents a temporary adjustment or the beginning of a broader revaluation across the global AI infrastructure ecosystem.
