Micron (MU) Stock Rockets 6.8% in Premarket as Analysts Bet Big on AI Memory Boom

Key Takeaways

• Micron Technology jumped approximately 6.8% in premarket trading Tuesday amid growing optimism around AI memory chip demand.
• Morgan Stanley analyst Joseph Moore identified the recent downturn as an attractive entry point, forecasting Q3 memory prices to increase roughly 25% versus Q2.
• KeyBanc boosted its price target to $1,750, while Bank of America placed Micron on its top-conviction US-1 roster.
• SK Hynix shares also gained ground, with leadership characterizing AI memory pricing as “abnormally high.”
• The chipmaker reports complete sellouts of HBM capacity through both 2026 and 2027.

Shares of Micron Technology experienced a sharp premarket rally on Tuesday, July 21, climbing about 6.8% as a series of optimistic Wall Street assessments and robust AI infrastructure spending forecasts reignited investor enthusiasm for memory semiconductor stocks.

The momentum stemmed from a research note issued by Morgan Stanley’s Joseph Moore, who characterized the recent decline in memory chip equities as a strategic buying window. Moore forecasted that third-quarter memory pricing would climb roughly 25% compared to second-quarter levels, citing ongoing supply constraints in the data center memory segment.

KeyBanc reinforced its bullish stance, maintaining an Overweight rating while elevating its price objective to $1,750. Bank of America delivered an even stronger endorsement by including Micron on its exclusive US-1 high-conviction roster. Consensus among 50 Wall Street analysts points to an average target of $1,548.86, accompanied by a predominantly Buy rating.

UBS contributed additional perspective, estimating total memory demand could expand 50% to 60% in the coming year, with AI-related demand potentially surging 60% to 100%. The investment bank also noted that Micron could execute share repurchases exceeding 40% of outstanding stock by 2028, following the expiration of buyback restrictions in December 2026.

SK Hynix participated in the rally as well, with American depositary receipts advancing 7.2% premarket while Korean shares finished the session up 4.1%. Company leadership’s characterization of AI memory pricing as “abnormally high” was interpreted by markets as evidence of sustained pricing strength throughout the industry.

Supply Constraints Driving the Narrative

High Bandwidth Memory, essential for powering AI training workloads and inference operations, continues facing significant supply limitations. Micron has confirmed its HBM manufacturing capacity is completely reserved through 2026 and 2027, positioning the company with substantial pricing authority in customer negotiations.

Market timing also appears favorable. Technology sector earnings reports commence Wednesday with Alphabet’s results, and market participants anticipate substantial AI infrastructure investment announcements from leading cloud providers — expenditures that directly convert into memory chip procurement.

UBS equity chief Ulrike Hoffmann-Burchardi projected that AI agents will represent over 90% of artificial intelligence activity by decade’s end, substantially amplifying computational requirements. The firm characterized the recent semiconductor stock correction as an attractive accumulation opportunity.

A Potential Headwind on the Horizon

However, not all indicators point upward. Reports emerged Monday suggesting Google is engineering a novel chip design that would integrate AI model components directly into hardware, potentially diminishing requirements for high-bandwidth memory and data movement. The chip reportedly targets a 2028 launch timeframe.

J.P. Morgan analyst Mixo Das countered demand skepticism, stating: “Memory demand has been questioned recently with reported technological and process breakthroughs reducing memory demand — but we are yet to see this in reality.”

Micron’s 52-week peak registers at $1,255. Premarket trading showed shares at $915.66, representing a $50.20 gain.
