Micron Technology Inc. (MU) shares climbed in premarket trading Tuesday, extending a rally that has propelled the memory-chip maker into the upper echelons of U.S. companies by market capitalization. The stock last traded at $576.45, valuing the company at approximately $658.3 billion.
AI Demand Reshapes Memory Market
The surge reflects a fundamental shift in Wall Street's perception of Micron. No longer viewed solely as a cyclical play on PC and smartphone memory, the company has vaulted from outside the top 100 U.S. companies by market cap to the brink of the top 15, crossing the $600 billion threshold for the first time last Friday. "As recently as a year ago, memory was considered one of the lower-value parts of the compute market," noted Gil Luria of D.A. Davidson.
Artificial intelligence data centers are driving this transformation, turning high-bandwidth memory (HBM) into a critical bottleneck rather than an afterthought. HBM stacks memory chips to shuttle vast amounts of data at high speeds with lower power consumption—essential for AI processors. In December, Micron announced it would exit the Crucial consumer memory business by February 2026, focusing entirely on advanced memory for AI data centers, a segment where Samsung Electronics and SK Hynix also compete.
Record Financial Results
Micron delivered financial results that justify its recent valuation surge. For fiscal second quarter, revenue hit $23.86 billion, a sharp jump from $8.05 billion a year earlier, with GAAP net income reaching $13.79 billion. The company guided third-quarter revenue to $33.5 billion, plus or minus $750 million. CEO Sanjay Mehrotra described memory as "a strategic asset" in the AI era.
Pricing Power and Risks
The rally remains heavily dependent on pricing, which cuts both ways. In its latest quarterly filing, Micron reported DRAM sales jumped 74% quarter-over-quarter, primarily due to average selling prices climbing in the mid-60% range. NAND sales surged 82%, driven by price increases in the high-70% percentage range. However, the filing also flagged potential volatility in memory prices and warned that new supply, if demand falters, could compress margins going forward.
Strategic Moves to Stabilize Demand
To mitigate cyclical risks, Micron is taking steps to lock in demand. During the March earnings call, Mehrotra disclosed the company's first-ever five-year strategic customer agreement, designed to improve supply-demand transparency for both Micron and its clients. He emphasized that AI has "fundamentally recast memory" as a strategic asset.
The broader market context is supportive. On Monday, Zacks highlighted Micron alongside Alphabet and SanDisk, pointing to AI-fueled gains across memory, storage, and cloud stocks. Alphabet's first-quarter earnings call underscored the trend: capital spending reached $35.7 billion, much of it directed toward technical infrastructure for AI.
Capital Expenditure Plans
Micron is ramping up its own spending to keep pace with surging demand. The company indicated that capital expenditures for fiscal 2026 should exceed $25 billion, primarily allocated to plants and equipment. An even larger increase is expected in fiscal 2027 as it shifts more investment toward HBM and DRAM. Construction-related outlays alone are projected to climb by more than $10 billion from the prior year in 2027.
Outlook and Risks
The key question is whether the memory shortage will persist long enough to support Micron's elevated valuation. As one of the most direct U.S. plays on AI-driven memory demand, the stock carries significant risk: if new supply floods the market, competitors ramp up, or data-center growth decelerates, the narrative could shift rapidly.
