Memory Revaluation Under HBM Structural Imbalance: Estimating Memory Weight from Micron’s Fierce Volatility to Signal an AI Storage Cycle Shift

In the first week of June 2026, the global semiconductor sector experienced a dramatic yet orderly revaluation of value. This time, market focus centered on the memory industry chain — a critical link bridging the foundational infrastructure of AI computing power. From Wall Street to Seoul, from AI data centers to smartphone manufacturing lines, the structural imbalance of HBM (High Bandwidth Memory) acted as a main thread, connecting Micron (MU)’s V-shaped volatility, the synchronized sell-offs of South Korea’s two giants, and the deep shifts occurring across the entire storage cycle.

On June 4th, Broadcom announced its Q2 earnings report. Earnings per share of $2.44, revenue of $22.2 billion, both surpassing market expectations. However, the capital market does not only look at the past but prices the future. Broadcom forecasted AI chip revenue for Q3 at $16 billion, below the widely expected $17.2 billion; full-year AI chip revenue guidance was $56 billion, also short of the $57.6 billion expected. This gap quickly propagated through the entire AI supply chain, causing the Philadelphia Semiconductor Index to fall by 5.45%. As the most direct downstream segment of the AI computing power supply chain, the memory chip sector bore the brunt of this sell-off.

Focusing on the core contradiction of HBM’s structural imbalance, starting from Micron’s movements, dissecting the divergence logic on both supply and demand sides, analyzing whether the synchronized decline of SK Hynix and Samsung signals a turning point in the cycle, and exploring how Gate’s latest stock trading features provide investors with a new channel to participate in this storage cycle transition.

HBM Structural Imbalance: A Market Where Supply and Demand Curves No Longer Intersect

In classical economics, supply and demand curves meet at an equilibrium price. But in the 2026 HBM market, the two curves are becoming nearly parallel.

Supply Side: The Capacity Ceiling of HBM3e Is Technology-Determined

As of Q1 2026, the three major manufacturers — SK Hynix, Samsung Electronics, and Micron — have essentially exhausted their HBM capacity. This is not a temporary demand surge but is dictated by the structural characteristics of HBM manufacturing processes.

According to EE Times, the wafer area consumed by HBM3e is about three times that of standard DDR5. The reason lies in HBM’s use of larger chip sizes and vertical stacking packaging, with yield losses during stacking further amplifying the demand for wafer capacity. Under the short-term constraints of equipment supply and factory construction, every wafer allocated to HBM means one less for LPDDR5X or standard DDR5. EE Times cites IDC analysts, describing this as a zero-sum game.

All three manufacturers are accelerating the conversion or expansion of NAND line space into TSV capacity to support high-end HBM production, but the pace of expansion cannot keep up with the deployment of AI infrastructure. Micron expects its gross margin in Q2 2026 to reach 68% — a profit margin that reflects the strong pricing power of HBM and explains why capacity resources continue to tilt toward AI-grade products.

Demand Side: Consumer Electronics Like Smartphones Are Being “Pushed Out”

The other side of the tight supply structure is a sharp decline in demand from consumer electronics. Industry research firm Counterpoint Research predicts global smartphone shipments in 2026 may decline by about 14%.

But this decline is not simply due to weak demand; it is a direct consequence of capacity being squeezed out of the HBM market. As wafer capacity is prioritized for HBM and AI-grade DRAM, smartphone manufacturers face supply bottlenecks for LPDDR5X and other mobile memories. TechCrunch notes that the core dilemma for smartphone makers in 2026 is: the pace of SoC performance improvements has outstripped storage bandwidth growth, with flagship models demanding more LPDDR5X and even LPDDR6, but yields for these advanced processes are still ramping up, making it difficult to meet market needs.

Smartphone brands face a dilemma of raising prices or reducing shipments. Some brands pass increased memory costs onto consumers, which in turn suppresses end-user upgrade demand, creating a negative feedback loop of shrinking demand. Memory contract prices on mobile devices doubled in 2025 and continued rising in the first half of 2026, further squeezing profit margins for mid- and low-end models.

This divergence between supply and demand encapsulates the core of “structural imbalance” — not a shortage of total volume, but a misallocation of resources.

From MU’s Volatility to Market Pricing Divergence

The current adjustment was triggered on June 4th. In the Nasdaq market, Micron Technology (MU) dropped 7.74% in a single day, closing at $996. Although the closing price remained near the $1,000 mark, it sharply retreated from the all-time high of $1,089.29 set on June 3rd.

June 5th was a day of concentrated sell-offs. MU’s intraday low was $864.01, a decline of over 20% from the previous day’s high. The closing price was $864.01, down 13.25%, with trading volume surging to 76.7 million shares, about twice the daily average. According to Dow Jones Market Data, MU’s market cap evaporated by approximately $94.24 billion in a single day.

The decline further spread to Asian markets in subsequent days. On June 8th, the KOSPI index in Korea plunged by 8.8% in the morning, triggering a 20-minute trading halt. By close, Samsung Electronics fell 10.18%, closing at 295,500 KRW; SK Hynix fell 7.68%, closing at 1.91M KRW. Based on June 5th’s close, SK Hynix and Samsung had fallen 9.92% and 6.40%, respectively. During that day, Samsung’s intraday low was 327,500 KRW, and SK Hynix’s was 270k KRW — both breaching key psychological levels.

Yet, the market’s reversal was equally swift. On June 8th, MU closed at $949.28, rebounding 9.87% in a single day, recovering much of its losses. On June 9th and 10th, MU continued its recovery, stabilizing in the $950–980 range. As of June 15, 2026, MU closed at $973.40, still about 10.6% below its June 3rd high, but this V-shaped movement alone indicates a divergence in market valuation logic for the stock.

Samsung and SK Hynix also showed intraday movements on June 12th, with KOSPI rebounding over 8%, then narrowing to within 8% and 4%, respectively. By June 15th, Samsung closed at 319,000 KRW, SK Hynix at 19.6B KRW, recovering from their lows but still below pre-crash levels.

The core driver of this pattern is market interpretation of the HBM structural imbalance. Bears see collapsing smartphone demand and Broadcom’s guidance below expectations as signs of an AI hardware bubble burst; bulls believe that the fundamentals of HBM capacity tightness remain unchanged, and the stock price decline is an overreaction driven by sentiment.

AI Storage Cycle Transition: From HBM3e to HBM4 Generational Shift

2026 marks a critical window for the HBM generation transition. Technologically, HBM3e remains the main consumption driver throughout the year, while HBM4 begins contributing revenue. NVIDIA’s new Rubin platform’s increased requirements for HBM4 specifications have delayed validation progress across the three major manufacturers. Samsung, leveraging its advanced process technology and chip performance, is expected to lead in certification; SK Hynix, with its existing collaborations, is also expected to maintain a significant share; Micron’s progress is comparatively slower.

TrendForce notes that, based on the expansion pace of TSV capacity at the three manufacturers’ Taiwan and Korea fabs, HBM4 capacity deployment will accelerate in the second half of 2026. However, HBM3e’s dominant consumption volume will not change throughout the year. This means 2026 will be a transitional year with coexistence of two generations, where the technological pace of different manufacturers will directly influence their market share and valuation.

For investors, the storage cycle transition is not simply “boom” or “bust,” but internal structural differentiation. AI data centers’ procurement commitments for HBM are locked in via long-term agreements, making this demand highly certain. In contrast, consumer electronics memory demand faces greater uncertainty. Morgan Stanley analyst Shawn Kim points out that the current chip cycle is still in an accelerating upward phase, with earnings revisions continuing upward, and the cycle’s persistence may surpass market expectations.

Gate’s Stock Trading Launch: Participating in MU and Samsung with USDT

During this period of intense volatility in the memory sector, Gate officially launched its stock trading feature in June 2026, providing users with a new channel to access US stock and Hong Kong stock markets. Gate Stocks supports direct trading of stocks and ETFs using USDT, covering major US markets like NYSE and NASDAQ, as well as over 1,000 Hong Kong stocks on the HKEX main board and GEM.

For investors interested in the memory industry chain, Gate Stocks offers direct access to trade Micron (MU), Samsung Electronics (SSNLF), and ETFs tracking the Korean market. The platform also introduced perpetual contracts in the stock section, settled in USDT, along with leveraged ETF tokens covering key tech and semiconductor sectors.

The core differentiators of Gate’s stock trading include:

Unified account system for cross-asset allocation.
Users do not need to open separate brokerage accounts; with Gate’s spot account and unified fund management, they can manage both crypto assets and traditional stock portfolios on a single dashboard.

USDT settlement eliminates FX friction.
Traditional US and Hong Kong stock trading requires currency conversion, which is inefficient and incurs costs. Gate allows direct USDT trading, with dividends and corporate actions paid out in USDT at par, lowering entry barriers.

Fragmented investment lowers participation costs.
The platform supports minimum trading units of 0.01 shares, roughly equivalent to $10 USDT, enabling retail users to participate in blue-chip stocks with smaller capital.

After updating to Gate App version 8.23.5 or above, users can access “TradFi—Stocks” to start trading. The platform’s VIP tier system offers lower trading fees, as low as 0.023%, for qualified users.

Conclusion

The early June 2026 memory sector adjustment is attributed by the market to “liquidity clearing after AI trading congestion.” Data shows signs of net outflows: as of June 5th, foreign investors net sold about 27 trillion KRW (~$196 billion) of Korean stocks over the past six trading days, with SK Hynix alone net selling about $12 billion.

However, the deeper logic behind this adjustment is not merely capital withdrawal. The structural imbalance of HBM — capacity locked into AI-grade products on the supply side, squeezed out of consumer electronics demand — is a medium- to long-term contradiction. As long as AI data center procurement agreements remain firm and HBM3e wafer consumption coefficients stay unchanged, this imbalance will not easily resolve. In the short term, geopolitical risks, macro rate adjustments, and liquidity effects from mega-IPOs like SpaceX will continue to induce volatility in the memory sector.

But for medium- to long-term investors, the 2026 storage cycle transition is not simply a sign of decline but a shift from the old cycle dominated by general DRAM to a new cycle led by HBM and AI-specific storage. In this process, MU, Samsung, and SK Hynix’s stock movements will increasingly depend on their position within the HBM technology roadmap rather than traditional memory cycle health. The new Gate stock trading features enable investors to seamlessly participate in the pricing discovery of these AI core assets using USDT within the same platform, balancing crypto market flexibility.

Every dramatic market adjustment is a redefinition of valuation logic. Understanding the structural imbalance of HBM is key to understanding the AI storage cycle transition.
