Micron Technology (MU) shares continued their rally on Tuesday, trading above the $1,000 mark for the first time, as the memory-chip maker's market capitalization approached $1.18 trillion. The milestone underscores Micron's emergence as a key player in the artificial intelligence boom, with demand for high-bandwidth memory (HBM) driving the stock's ascent.
Shares last changed hands at $1,035.50, extending a surge that has made Micron one of the top AI plays on Wall Street. The stock's rise comes as analysts from Raymond James, D.A. Davidson, and UBS raised their price targets, citing robust demand for HBM, tight supply conditions, and a sold-out inventory for 2026.
Analyst Upgrades and Price Targets
Raymond James analyst Melissa Fairbanks lifted her price target on Micron to $1,100 from $530, maintaining an Outperform rating ahead of the company's fiscal third-quarter earnings report scheduled for June 24. The upgrade reflects expectations of sustained long-term demand, constrained supply, and favorable pricing dynamics.
D.A. Davidson's Gil Luria took an even more bullish stance, raising his target to $1,500 from $1,000. Luria noted that HBM's growing role in data center architectures and longer-term customer contracts are shifting memory away from its traditional commodity status. UBS set its target at $1,625 last week, the highest among 46 brokerages tracking Micron, according to LSEG data cited by Reuters.
AI-Driven Demand for High-Bandwidth Memory
The surge in Micron's stock reflects a broader trend where AI demand is expanding beyond Nvidia's chips into memory components. High-bandwidth memory, which stacks memory chips to accelerate data transfer between AI processors, is becoming a critical bottleneck in AI system performance. DRAM, the main memory in PCs and servers, is also benefiting from the AI boom.
"Micron sits at the center of it," Art Hogan, chief market strategist at B. Riley Wealth, told Reuters. The company's position was further highlighted at the Computex trade show in Taipei, where Micron announced plans to showcase new memory and storage solutions for AI data centers and edge devices. Sumit Sadana, Micron's chief business officer, noted that AI context lengths have increased 30-fold year over year, emphasizing that "system performance is now driven by memory bandwidth and memory capacity."
Market Share and Supply Dynamics
Micron, along with SK Hynix and Samsung Electronics, dominates the HBM market. SK Hynix held a 58% global market share in the first quarter, while Samsung and Micron each accounted for 21%, according to Counterpoint Research data reported by Reuters. Micron's supply remains a key focus, with the company stating that all of its 2026 HBM inventory is already sold out. Reuters also reported that Micron's HBM4 line is now in production, with volume shipments of its HBM4 36GB 12-high modules beginning in the first quarter of calendar 2026, targeting Nvidia's Vera Rubin platform.
SK Group Chairman Chey Tae-won announced on Tuesday that SK Hynix plans to "double the whole capacity over the next five years." Samsung has started shipping HBM4E samples and displayed a mock-up of a future HBM5 chip, indicating intense competition in the space.
Risks and Outlook
Despite the bullish sentiment, risks remain. A bearish note from Seeking Alpha on May 31 warned that capital spending across the sector and new mega-fab buildouts from top DRAM manufacturers could begin to alleviate shortages and pressure prices by 2028 or 2029. Chey also cautioned that "excessive price increases" might harm the broader AI ecosystem.
For now, Micron is trading as a bottleneck play, with investors focused on the fiscal third-quarter earnings report due June 24. The market will be looking for evidence that tight supply and AI server demand can support rising profit estimates, even as the stock continues to climb.
