SK Hynix’s HBM Dominance Meets a Reality Check: From ‘Chipflation’ Warnings to Nasdaq Correction

SK Hynix heads into its quarterly earnings on July 24 with a deepening disconnect. The memory maker holds a 58% share of the high-bandwidth memory (HBM) market, its HBM capacity is sold out through next year, and management describes the current environment as a sellers’ market. Yet the stock has tumbled nearly 40% from the post-Nasdaq peak hit earlier this month, caught between a macro-driven pullback and growing anxiety that the artificial-intelligence boom may be overheating.

The July 10 initial public offering of SK Hynix’s American Depositary Receipts on the Nasdaq was a landmark event. The company raised $26.5 billion, with demand outstripping supply sevenfold. But the euphoria faded quickly. By Friday, the Seoul-listed shares had fallen 11.53% in a single session, capping a seven-day losing streak of 15.5%. The ADRs closed at $154.03 on July 17, a 24.6% premium to the domestic stock, but the arbitrage window that opens on July 29 may not offer much relief: only 2.5% of the depositary receipts can be converted initially, with a 25% registered custody framework serving mainly as a backstop.

Chairman Chey Tae-won used a mid-July appearance at the Jeju Forum to warn that the market is heading toward “chaos.” He said memory prices are “abnormally high” and coined the term “chipflation” to describe a price spiral that could invite geopolitical retaliation as governments compete for scarce supply. Demand for AI semiconductors, he noted, could rise 60% to 100% next year, while the broader memory market may grow 50% to 60% — with virtually no new capacity coming online. Customers are already demanding five to six times their previous delivery volumes.

To close the gap, SK Hynix is accelerating its Yongin cluster to February 2027, converting its Cheongju M15X facility for HBM production, and planning roughly 400 trillion won for two new plants in Gwangju. The company is also evaluating a first US production site, complementing the $3.87 billion packaging plant already under construction in Indiana, which is slated for mass production in the second half of 2028. US Commerce Secretary Howard Lutnick has been pressing for more Korean investment stateside. Chey even cited Elon Musk as an example of a new entrant that could jump into chipmaking if prices stay elevated — an argument he used to underline the urgency of expanding supply.

Should investors sell immediately? Or is it worth buying SK Hynix?

Inside the company, a generous bonus formula is stirring debate. Under the current system, 10% of operating profit goes to employee bonuses, and this year’s payout has hit 2,964% of base salary. Chey signaled he is open to revising the structure if it hurts shareholders or suppliers, possibly by shifting part of the payout to stock rather than cash. No decision has been reached — further talks between management and staff are needed.

Meanwhile, the macro backdrop has turned less supportive. On July 16, the Bank of Korea ended a three-year pause and raised its key rate to 2.75%, citing inflation partly driven by the chip boom. Markets are pricing in at least one more hike, which could cool domestic investment and raise the cost of capital for the capital-intensive semiconductor industry. Added to that, 45% of global fund managers surveyed by Bank of America now call an AI bubble the biggest tail risk, and the PHLX Semiconductor Index is already 20.34% below its 2026 high.

The bull case still has plenty of ammunition. SK Hynix is believed to have secured 50% to 70% of Nvidia’s HBM4 orders, positioning it as the main beneficiary of the upcoming Vera Rubin architecture. The stock trades at just 7 times 12-month forward earnings — a steep discount to US rival Micron. Barclays initiated coverage of the ADR with an overweight rating and a $330 price target. Among Korean brokerages, targets range from 1.85 million won (BNK, hold) to 4.2 million won (KB and Mirae Asset). Mirae Asset’s Kim Yeong-geon kept his 4.2 million won target but cut his earnings estimate by 12%, now forecasting second-quarter operating profit of 62.3 trillion won.

SK Hynix at a turning point? This analysis reveals what investors need to know now.

The bear camp counters that memory cycles inevitably peak when massive capacity additions flood the market. Micron and Samsung are also closing in on the trillion-dollar market-cap mark and expanding their own HBM4 production, raising the risk of an oversupply by 2027. The technical picture offers little comfort: the relative strength index sits at 40.5, signalling possible stabilization but no catalyst for a sustained rebound.

The next few days will be pivotal. Alphabet reports on July 23, and any sign that Big Tech is throttling back its AI infrastructure spending would undercut the entire HBM growth thesis. South Korea’s second-quarter GDP figures land the same day, offering a read on the economy’s health as rates rise. SK Hynix’s own numbers on July 24 will be scrutinized for confirmation of the Nvidia order share and updates on the utilization rates of its new expansion projects. If those data points hold, the current 15.86% gap to the 50-day moving average could mark an attractive entry. If not, the sell-off may have further to run.
