Micron MU stock price increased 260% year-over-year; can the surge in AI server DRAM demand continue?

As of June 18, 2026, according to Gate stock market data, Micron Technology (MU) closed at $1,043.19, up 2.20% for the day, with an after-hours increase of 4.8%, temporarily reporting $1,092. Just two days ago, on June 16, the stock hit a record high of $1,110.44 intraday. The current after-hours price is only about 1.7% below this all-time peak.

Since the beginning of this year, Micron's stock price has increased approximately 260%. On June 17, Deutsche Bank significantly raised its target price for Micron from $1,000 to $1,500, maintaining a "Buy" rating. Based on the June 17 closing price of $1,043.19, this target implies about 30% potential upside; using the June 16 closing price of $1,020.76 as a baseline, the upside could be approximately 47%.

The core driver behind this rally is the memory supply shortage triggered by the rapid proliferation of AI applications. Deutsche Bank analyst Melissa Weathers pointed out that the tight supply of DRAM "may persist until 2028 or even longer."

Micron's stock surges 260% and nears all-time high, is the momentum driven by cyclical or structural factors?

Understanding the nature of Micron's recent surge is essential for assessing its sustainability. The traditional memory chip industry is known for its strong cyclicality—supply-demand mismatches cause sharp price swings, with stock prices fluctuating accordingly. However, the logic driving this rally differs fundamentally from past cycles.

From Q1 2025 to Q2 2026, contract prices for DRAM increased by over 300%, and NAND Flash contract prices rose by more than 250%. For example, the spot price of DDR5 16G chips soared from about $5.50 in May 2025 to over $40 in May 2026, a 12-month record-breaking increase. According to Gartner, in 2026, DRAM prices rose by 125%, and NAND prices by 234%.

The magnitude of these price increases surpasses any previous cycle. During the 2017-2018 storage price cycle, DRAM per-bit prices increased by about 90%. In this cycle, some analysts estimate that DRAM per-bit prices could increase by 275% to 300% from 2025 to 2027.

Behind these extraordinary gains is a fundamental shift in demand structure. In traditional cycles, storage demand is driven by PC and smartphone upgrade cycles—volatile, consumer electronics-driven demand. In contrast, the current demand surge is primarily driven by infrastructure buildouts for AI data centers—a long-term project requiring trillions of dollars in capital expenditure over several years.

How AI data centers are reshaping the fundamentals of storage demand

AI servers demand vastly more storage than traditional servers. Traditional servers typically have 128GB to 256GB of DRAM, whereas AI-optimized servers now feature 512GB to 1TB or more. The demand for HBM (High Bandwidth Memory) per AI server is 8 to 10 times that of traditional servers. In 2026, global AI server shipments are expected to surpass 3 million units, driving the HBM market to over $20 billion.

HBM is a core component of AI computing hardware. In 2026, the growth in HBM demand is mainly driven by capacity upgrades in AI ASICs, with each AI chip's HBM capacity increasing sharply from 96GB/192GB to 216GB/288GB. With NVIDIA's new Rubin Ultra platform, GPU configurations will further increase HBM capacity to 384GB per unit. TrendForce estimates that HBM wafer shipments will account for about 30% of total DRAM wafer shipments by 2027, up from 18% in 2025.

AI-driven demand for storage extends beyond HBM. Deutsche Bank analysts note that the next supply tightness will be driven by increased demand for traditional DRAM and low-power DRAM, as the development of AI inference accelerators makes workloads more memory-intensive. Micron expects that by the end of 2026, the bit demand for data center DRAM and NAND will exceed 50% of the total industry market.

This indicates that storage demand growth is spreading from niche segments like HBM to the entire DRAM and NAND markets.

Why will the supply-demand gap persist until 2028: supply-side constraints

Deutsche Bank believes that the industry imbalance will continue into late 2026, 2027, and even 2028, and may worsen further. This outlook is not based on optimistic demand assumptions but on multiple hard constraints on supply.

From a capacity expansion timeline perspective, semiconductor fabs take time to build and ramp up. The industry’s key new lines, such as Micron’s ID1 plant, are expected to start production no earlier than mid-2027, with a 12- to 18-month ramp-up period needed to reach full capacity and stable supply, meaning full-scale supply won't be achieved until 2028.

Goldman Sachs provides quantitative forecasts: from 2026 to 2028, the global DRAM supply-demand gap is projected at 5.0%, 5.9%, and 3.9%, respectively; NAND flash shortages are expected to be 4.4% and 4.6% in 2026 and 2027, narrowing slightly to 3.0% in 2028; HBM shortages are the most acute, with gaps of 5.4%, 6.0%, and 4.3%. 2027 is likely to be the peak year for supply-demand imbalance in the storage industry.

It’s important to note that even if new capacity expansion plans are announced and accelerated within the past 180 days, the tight supply situation is expected to persist. This indicates that constraints are not only due to insufficient capacity but also due to the rigid timing of capacity releases.

Meanwhile, major cloud providers like Microsoft, Google, Meta, and Alibaba Cloud are signing long-term supply contracts of 3 to 5 years to secure capacity and lock in prices through prepayments. This large-scale locking of supply reduces spot market liquidity, further tightening supply for end markets.

Can earnings support valuation: key earnings report points

Micron plans to release its Q3 FY2026 results on June 24, 2026. Deutsche Bank expects that tailwinds in the memory market will boost Micron’s revenue for this quarter to $35.1 billion, above the previous estimate of $33.5 billion. Goldman Sachs is even more optimistic, forecasting revenue of $37.6 billion, gross margin of 83.4%, and EPS of $22.07, compared to market consensus of $34.4 billion, 81.9%, and $19.74.

Previous earnings reports have already shown strong growth momentum. In Q2 FY2026, Micron’s revenue surged to $23.86 billion, nearly tripling from $8.05 billion a year earlier and beating the expected $20.07 billion; adjusted EPS was $12.20, well above the forecast of $9.31. Non-GAAP gross margin was 74.9%, far exceeding the sub-30% levels typical of past storage downcycles.

Breaking down by business, DRAM revenue reached $18.8 billion, up 207% year-over-year, accounting for 79% of total revenue; NAND revenue was $5 billion, up 169%. Data centers have become Micron’s core source of revenue and profit.

Citigroup analysts estimate that the average selling price of DRAM will increase by 200% in 2026, with spot prices up 52% since early January and trading at a premium of 21% over current contract prices. This price spread suggests further upward potential for contract prices.

Wall Street divergence and consensus: 30% upside or overvaluation?

Despite Deutsche Bank’s significant upward revision attracting market attention, Wall Street’s views on Micron are not unanimous.

According to LSEG data, out of 47 analysts covering Micron, 44 rate it as “Buy” or “Strong Buy,” with target prices up to $1,625. UBS last month raised its target from $535 to $1,625, and TD Cowen also increased its target to $1,500. TD Cowen analyst Krish Sankar stated that the revised target is based on his forecast of $150 per share in calendar 2027 earnings. Morgan Stanley recently raised its target from $520 to $1,050. Aletheia Capital set a target of $1,600.

However, cautious voices remain. Some analysts note that Micron’s median target price is $949, implying about 8% downside from current levels. Market participants point out that the recent surge in memory stocks has already priced in AI shortages, price increases, and profit margins, and whether the rally can continue depends on sustained AI capex and whether supply tightness persists into next year.

This divergence essentially reflects differing perceptions of Micron’s valuation framework. Historically, the market has viewed Micron as a cyclical storage stock, valuing it based on peak historical price-to-book ratios. The optimistic camp argues that under AI-driven structural demand, valuation should shift to a growth-oriented tech model based on expected earnings.

Micron’s current static P/E ratio is about 48, but the forward P/E for 2026 has been significantly compressed. Whether this valuation is justified depends on whether the market perceives it as a “cyclical stock” at the cycle peak or a “growth stock” with earnings growth expected to justify higher valuations.

Capacity race and long-term trends: boundaries of the memory supercycle

The memory chip industry is experiencing a capacity expansion race. Micron’s capital expenditure for FY2026 has been increased to over $25 billion. However, the release of new capacity is constrained by the inherent time rigidity of semiconductor manufacturing.

On the demand side, AI infrastructure investments continue to grow. Morgan Stanley estimates that by 2028, AI construction will require an additional $1.5 trillion in external funding. These capital expenditures will translate into ongoing procurement of memory chips. Deutsche Bank analysts explicitly state that the supply-demand imbalance will persist into late 2026, 2027, and possibly 2028, and may worsen.

TD Cowen offers a more critical structural perspective: the role of memory in AI is structural rather than cyclical. Even considering specification adjustments, the DRAM content per unit of power consumption continues to increase, implying that AI infrastructure buildout will drive persistent growth in memory intensity, unlike traditional server cycles that tend toward mean reversion.

However, the supercycle also faces boundary conditions. Samsung and SK Hynix are accelerating to catch up with Micron’s HBM leadership. If Samsung’s HBM4 yields improve to match Micron’s by year-end, Micron’s pricing advantage will diminish. Additionally, consumer electronics end markets are already feeling cost pressures, with some brands beginning to cut orders, which could suppress the second-half growth in consumer DRAM prices.

The ongoing rise in storage prices is beginning to have a negative feedback effect on downstream demand—an unavoidable pattern in cyclical industries. Whether the supercycle can continue depends ultimately on whether AI data center procurement can sustain demand growth sufficient to offset the contraction in consumer electronics.

Summary

Micron’s 260% rally this year and its intraday breakthrough above $1,110 reflect the concentrated impact of the AI infrastructure wave on storage chips. Deutsche Bank’s target price upgrade to $1,500 hinges on the view that AI-driven storage demand is a sustained structural trend rather than a short-term spike; meanwhile, supply-side capacity expansion is limited by semiconductor manufacturing time rigidities, with imbalances expected to persist until at least 2028.

As of after-hours June 18, Micron’s stock price has approached its all-time high. Whether the potential 30% to 47% upside can materialize depends on multiple factors: whether the June 24 earnings report can validate Deutsche Bank and Goldman Sachs’ optimistic forecasts, whether HBM capacity expansion proceeds as planned, and whether declining consumer electronics demand will weigh on overall storage prices. The narrative of a storage supercycle is established, but the cycle’s evolution is never a straight line.
