In June 2026, the hottest narrative in global capital markets is no longer GPU shipment volumes—it’s the supply-demand gap for memory chips.
On June 12, SanDisk (SNDK) briefly approached the $2,000 mark during intraday trading. Although the stock closed at $1,991.55 on June 16, down 5.52% for the day, its year-to-date gain remains a staggering 738.97%, with a 52-week increase of 4,404.75%. During the same period, Micron Technology (MU) saw its share price rise over 200% for the year, with its market cap crossing the trillion-dollar threshold.
This rally isn’t driven by short-term speculation. Instead, it’s fueled by a structural supply-demand imbalance triggered by the expansion of AI infrastructure. Goldman Sachs has dubbed this the "multi-year AI memory supercycle." Morgan Stanley’s latest report states bluntly: DRAM has become the "primary bottleneck" in AI infrastructure development.
While the market remains focused on compute chip giants like NVIDIA, a deeper industry logic is emerging. In the age of AI inference, the scarcity of "memory capacity" is beginning to surpass that of "compute power."
Supply-Demand Imbalance: The Most Severe Memory Shortage in 15 Years
On the demand side, AI servers require far more memory capacity than traditional architectures. According to Gartner research, a single AI server uses 8 to 10 times more DRAM and over 3 times more NAND flash than a conventional server. The firm predicts global AI server shipments will reach 1.5 million units in 2026, up 180% year over year.
More importantly, the structure of demand is changing. Leading cloud providers like Amazon, Microsoft, and Google have already locked in their entire memory supply for 2027, and are even planning allocations for 2028. Enterprise customers now prioritize securing capacity to ensure compute delivery, rather than adjusting procurement based on price fluctuations. This fundamentally breaks the old cycle of "price hikes lead to capacity expansion, oversupply leads to price drops."
On the supply side, multiple hard constraints are at play. Building memory wafer fabs and advanced HBM packaging capacity takes two to three years, and capital expenditures cut during previous industry downturns can’t be converted into effective capacity in the short term. Morgan Stanley analyst Joseph Moore emphasizes that the key constraint on supply growth isn’t manufacturers’ willingness to invest, but physical limitations—such as insufficient cleanroom capacity and restricted supply of ASML EUV lithography machines.
Industry research indicates that in 2026, the supply-demand gaps for DRAM, NAND flash, and HBM are expected to reach 4.9%, 4.2%, and 5.1%, respectively—the highest levels since 2011. SEMI data shows the HBM market is projected to grow 58% in 2026 to $54.6 billion, accounting for nearly 40% of the DRAM market.
Price trends reflect this tight environment. TrendForce reports that in Q1 2026, contract prices for generic DRAM rose 93% to 98% quarter-on-quarter, while NAND contract prices increased 85% to 90%. Morgan Stanley’s financial models show DRAM prices surged 40% in the March–May quarter, with another 15% increase expected in the June–August quarter.
Omdia has raised its 2026 semiconductor industry revenue forecast to 62.7% growth, mainly driven by strong DRAM and NAND demand amid supply shortages. Global semiconductor revenue in Q1 2026 rose 27% quarter-on-quarter to $319 billion, with memory revenue up over 80% and DRAM and NAND nearly doubling in a single quarter. Memory now accounts for more than 40% of total semiconductor revenue, far above the long-term average of around 20%.
Investment Bank Perspectives: Dual Endorsement from Morgan Stanley and Goldman Sachs
In early June, Morgan Stanley released a major research report, doubling its target price for Micron from $520 to $1,050 and raising SanDisk’s target price from $1,100 to $1,750.
The core conclusion: this round of memory shortage will last at least two to three years, possibly longer. Based on forecasts for continued DRAM price increases, Morgan Stanley raised its SanDisk EPS estimates for 2026 and 2027 by 12% and 24%, respectively.
Despite SanDisk and Micron’s astonishing gains this year, Morgan Stanley believes both still have room to run. The current share prices for both companies imply a forward P/E below 10x for fiscal 2027, suggesting significant upside potential for valuation expansion.
Goldman Sachs maintains a bullish outlook on memory chip stocks, predicting AI-driven shortages will persist through 2028. Goldman expects a 5.0% DRAM supply gap in 2026, widening to 5.9% in 2027.
Why SanDisk Deserves More Attention Than NVIDIA
This argument doesn’t diminish NVIDIA’s industry status; it highlights differences in market pricing efficiency.
As the "pick-and-shovel" provider of AI compute power, NVIDIA’s valuation fully reflects the market’s consensus on AI compute demand. As of June 2026, NVIDIA’s market cap is at an all-time high, and performance expectations are well priced in. In contrast, the memory chip sector’s valuation reset is just beginning.
SanDisk stands out for its pure-play memory exposure. Unlike Micron, which covers both DRAM and NAND, SanDisk focuses exclusively on NAND flash—one of the fastest-growing storage categories in AI data centers. Reports indicate SanDisk has secured multi-year NAND supply contracts worth hundreds of billions of dollars. In Q3 FY2026 (ending April 3, 2026), SanDisk’s revenue jumped 97% quarter-on-quarter and 251% year-on-year to $5.95 billion. Crucially, SanDisk has sold out all memory products for 2026 and faces excess demand for 2027.
From a valuation perspective, both Micron and SanDisk trade at less than 10x forward P/E for fiscal 2027, while NVIDIA’s multiples are at industry highs. With the supply-demand gap widening, memory manufacturers may see earnings upgrades that exceed market expectations—this is the rationale behind Morgan Stanley’s 24% upward revision of SanDisk’s 2027 EPS forecast.
Top Institutional Signals: David Tepper Builds a Position in SNDK
When a stock is up over 500% in a year, most investors take profits. Billionaire investor David Tepper chose a different path.
According to Appaloosa Management’s 13F filing, Tepper initiated a new position in SanDisk during Q1 2026, acquiring about 281,250 shares. The market sees this move as a strong endorsement of SNDK’s continued upside potential.
Tepper’s portfolio direction is highly focused. At the end of Q1 2026, Appaloosa Management’s total holdings were valued at about $6.9 billion, with the number of stocks reduced from 38 to 31. The top five holdings accounted for over 48% of the portfolio. Capital is shifting away from traditional consumer, China ADRs, and airline sectors, concentrating on AI infrastructure, power, and memory chips.
Tepper isn’t the only institutional investor bullish on memory. Even after SanDisk and Micron’s remarkable rallies, several Wall Street analysts believe AI-driven memory shortages could last another two to three years, suggesting further upside for memory stocks.
Gate Stock Trading: Capture AI Memory Investment Opportunities with USDT
For investors interested in the AI memory supercycle, efficiently and cost-effectively trading core US stocks like SanDisk and Micron is a practical concern.
On June 1, 2026, Gate officially launched its real stock trading service, becoming one of the first crypto platforms to directly access the US stock market. As of June 17, 2026, Gate’s stock business fully covers both US and Hong Kong core securities markets, supporting over 11,500 stock-related assets. The US segment features more than 10,000 real stocks and ETFs, covering the NYSE, Nasdaq, NYSE Arca, NYSE American, and BATS. The Hong Kong segment launched on June 11, initially covering over 1,500 assets.
Gate stock trading offers three core advantages:
First, trade real stocks directly with USDT. Traditionally, crypto users investing in US stocks face a lengthy process: "sell crypto → withdraw fiat → cross-border transfer → broker account funding," which takes days and incurs multiple fees. Gate streamlines this to "USDT in your account → transfer to stock account → one-click stock purchase." No currency conversion, no cross-border transfers, no extra brokerage accounts needed.
Second, extremely low entry barriers. Gate US stocks support fractional trading starting from just 0.01 shares, allowing users to invest in leading US stocks with as little as $1. This is especially useful for those wanting to test the waters with high-priced stocks like SanDisk—SNDK trades near $2,000, and traditional brokers require whole-share purchases, making entry costly. Fractional trading drastically lowers the participation cost.
Third, asset security and rights protection. Gate connects directly with Alpaca, a compliant broker-dealer with US clearing qualifications. Every stock purchased is backed by real assets independently held in the DTC system. During holding periods, users automatically enjoy full shareholder rights, including cash dividends, splits, and corporate actions. Gate US stocks also support pre-market and after-hours trading, extending trading hours to 16×5 and enabling timely responses to earnings and market events.
Hong Kong and US stocks share the same account system—users simply transfer USDT from their spot account to their stock account to participate directly. One account manages holdings across both markets, eliminating the friction of maintaining multiple broker relationships.
Conclusion
Technical indicators for the memory sector now show overbought signals. SanDisk dropped 5.52% in a single day on June 16, with an intraday swing of 8.88%, indicating heightened volatility at elevated levels. While AI-driven structural demand provides stronger support for memory market strength than ever before, any asset that accumulates such massive gains in a short period faces objectively rising pullback risk.
Investors should monitor several key variables: the outcome of HBM contract renegotiations at the end of 2026, the capital expenditure pace of major cloud providers, and the actual progress of memory chip capacity expansion. Micron plans to repurchase $50 billion in stock across fiscal 2027 and 2028, making the timing of this catalyst worth watching.
The AI memory supercycle is one of the most pivotal industry narratives in the capital markets of 2026. SanDisk’s 700%+ gains this year are not mere speculative hype—they reflect the convergence of supply-demand fundamentals, institutional consensus, and industry trends. For investors looking to participate, Gate’s USDT-based direct US stock trading service could be the efficient bridge connecting crypto assets and traditional financial markets.
