Micron Stock Hits $1 Trillion Market Value As AI Demand For Memory Chips Rises

Micron Technologies hit a $1 trillion market valuation for the first time on May 26, 2026, as AI-driven demand for memory chips propelled its stock to record highs. The company’s shares surged as much as 19.3% in a single session, later trading 17.4% higher at $881.6, according to Reuters. Brokerage UBS nearly tripled its price target for Micron’s stock from $535 to $1,625, citing long-term agreements and fixed pricing opportunities tied to AI infrastructure growth. The milestone underscores memory chips’ critical role in AI systems, as investors pivot from graphics processors to companies like Micron, which manufactures chips essential for data storage and processing. The company’s 2026 high-bandwidth memory (HBM) supply is already sold out, with next-generation HBM4 products now in production, highlighting strong demand outpacing supply. Micron’s stock has risen over eightfold in the past year, fueled by robust earnings and supply chain constraints granting pricing power. Micron’s ascent positions the U.S. as a key player in the global memory chip market, traditionally dominated by Asian firms like Samsung Electronics, which already surpassed the $1 trillion valuation, and SK Hynix, nearing the same milestone. The company’s growth reflects broader shifts in AI investment, with other tech stocks—including Intel, Qualcomm, Marvell Technology, and Advanced Micro Devices—also reaching new highs amid Big Tech’s aggressive spending on AI infrastructure. The surge follows Micron’s rapid expansion, with its valuation crossing $700 billion just weeks prior, marking it as one of the most valuable tech firms globally. Analysts attribute the rally to Micron’s strategic position in AI-driven markets, where memory chips are becoming increasingly indispensable for data-intensive applications.
