Micron's Capacity Crunch Defines the Next Phase of the AI Memory Race

Micron's HBM4 memory for AI is sold out for years due to production limits, granting huge pricing power. But a US listing by rival SK Hynix may challenge its valuation premium.

Micron Technology finds itself in an enviable yet challenging position: its next-generation HBM4 memory chips are sold out through the end of 2026. This shortage isn't driven by a lack of orders but by a fundamental inability to produce more. Industry data indicates the company can currently fulfill only 50 to 66 percent of demand from its largest customers, a direct result of insufficient cleanroom space. This structural scarcity is the central narrative for the semiconductor giant's stock.

The sold-out status for chips destined for AI infrastructure like NVIDIA’s Vera Rubin architecture grants Micron extraordinary pricing power. It has led to record gross margins even as consumer demand in smartphone and PC segments softens. This strength is being locked in through multi-year supply agreements with hyperscalers, which include price floors and prepayments, according to analysts at KeyBanc. For the current third fiscal quarter, Micron has guided for revenue of $33.5 billion with gross margins around 81 percent.

A Valuation Crossroads Approaches

The investment case, however, faces a pivotal shift. For years, Micron was the sole US-listed pure-play providing direct exposure to the DRAM market. That monopoly is ending with SK Hynix’s application to list American Depositary Receipts on US exchanges. Market observers anticipate this will increase competition for capital and could erase part of the valuation premium Micron has historically enjoyed. Some analysts see this as a necessary market evolution, while others, like those at BTIG, interpret the launch of a new DRAM ETF as a contrarian sell signal suggesting the memory trade may be entering a late stage.

Wall Street’s ratings reflect this dichotomy. Mizuho recently raised its price target to $545 from $530, reaffirming an Outperform rating following a record second fiscal quarter with revenue of nearly $24 billion. KeyBanc maintains a $600 target, while Needham & Company lifted its target to $500. In contrast, Erste Group downgraded the stock to Hold, citing heavy capital expenditures pressuring free cash flow despite a robust revenue forecast of $109 billion for fiscal 2026.

Expansion Plans and Trader Sentiment

The path forward hinges squarely on Micron’s ability to expand its manufacturing footprint. The company’s planned greenfield projects in Idaho and New York represent the only realistic solution to the chronic supply shortage. Without significant new cleanroom space, its growth remains structurally capped regardless of soaring AI demand.

Traders in the options market are positioning for near-term movement. Last Friday, roughly 60 percent of the approximately 733,000 contracts traded were bullish calls. Total open interest stands at nearly 2.9 million contracts, about 110 percent of the 30-day average, indicating heightened expectations for volatility.

The stock, trading near €387 in Frankfurt, sits roughly four percent below its 52-week high. It has still surged over 44 percent year-to-date, with a Relative Strength Index around 37 suggesting recent selling pressure has pushed it into technically oversold territory. Recent insider sales by EVP Sumit Sadana and Chief People Officer April Arnzen, executed under pre-arranged 10b5-1 plans, are not viewed as a change in business outlook but as routine portfolio management.

The coming quarters will test whether Micron’s pricing discipline in the DRAM and NAND markets can hold and if its massive capacity investments can finally bridge the gap between overwhelming demand and constrained supply.
