Micron's AI Memory Thesis Strengthens on Two Fronts: A $168B HBM Market and a 256GB DDR5 Milestone, Yet Shares Take a Breather

Micron ships faster DDR5 modules, BofA raises target to $950, and DRAM supply tightness through 2026 fuels margin surge.

The storyline around Micron Technology has become unusually bifurcated: operational momentum is firing on all cylinders, yet the stock suffered its sharpest single-day pullback in months on Friday. The memory chipmaker is riding twin waves of product innovation and long-term market revaluation, but the 8.11% drop to €624 in German trading suggests that even the most bullish narratives need occasional cooling.

On the product side, Micron has started shipping samples of a 256GB DDR5 registered memory module to key partners in the server ecosystem. Built on the company’s 1-gamma process platform, the module achieves data rates of up to 9,200 megatransfers per second—more than 40% faster than current production modules. It also slashes power consumption by over 40% when replacing a two-module configuration. For hyperscale data centres running energy-intensive AI workloads, that combination of bandwidth, capacity, and efficiency is precisely what the market demands.

At the same time, Bank of America delivered a dramatic repricing of the entire AI memory opportunity. Analyst Vivek Arya lifted his price target on Micron from $500 to $950, driven by a revised estimate for the addressable AI data-centre systems market—now $1.7 trillion by 2030, up from $1.4 trillion. Crucially, high-bandwidth memory (HBM) is no longer viewed as a cyclical commodity but as a structural bottleneck in AI infrastructure. BofA projects the HBM market alone will reach $168 billion by the end of the decade, with memory content per AI accelerator climbing from 187GB to 464GB.

That long-term thesis stands in stark contrast to the stock’s recent price action. Friday’s sell-off leaves Micron shares roughly 9% below their all-time high, though the bigger picture remains staggering: the equity is still up 62.54% on a monthly basis and has more than doubled this year with a 131.97% year-to-date gain. The relative strength index sits at 77.0, firmly in overbought territory, suggesting the correction is as much a technical reset as a fundamental reassessment.

Underpinning the entire story is a supply dynamic that defies the memory industry’s historical boom-bust cycles. Micron expects DRAM and NAND to remain tight through at least 2026, with meaningful new capacity additions unlikely before 2028. Expansion at its Idaho and Singapore fabs, and at the Tongluo site in Taiwan, will add volume only gradually—Tongluo's incremental output is not expected until late 2027. This structural scarcity is already feeding through to pricing: DRAM contract prices are forecast to rise 58% to 63% in the current quarter, and Gartner expects a full-year surge of 125%. Those price increases explain why margin guidance has jumped so dramatically.

For the fiscal third quarter ending in June, Micron management has set a revenue target of $33.5 billion—a 260% leap from the prior year—and a gross margin of roughly 81%. Adjusted earnings per share are pegged at $19.15, though another source places the forecast at $18.90, reflecting the narrow range of expectations around such elevated numbers. Full-year analyst consensus stands at $57.71 EPS, climbing to nearly $98 the following year. Those projections, however, depend on sustained pricing power and unbroken demand from cloud hyperscalers.

One note of caution came from insider trading activity. Director Steven Gomo sold 2,000 shares on May 16 at around $787, contributing to a $54 million total of insider sales over recent months. While not necessarily a bearish signal, it adds to the debate about whether the current price fully reflects the risks embedded in a fast-changing memory cycle.

The near-term catalyst queue is dense. Nvidia’s earnings on May 20 will provide the next sentiment check for HBM demand, followed by the Computex trade show in early June. Micron itself is expected to report its quarterly results around June 24. Until then, the AI tailwind remains intact, but after a rally of this magnitude, even small doubts about pricing, margins, or delivery timelines can trigger outsized moves. The gap between Micron’s operational strength and its stock’s recent stumble is a reminder that in overheated markets, the best stories can still pause for breath.
