Micron and Sandisk Rally on Strong Memory Demand
Shares of Micron and Sandisk climbed after a Melius Research report said memory demand could remain high through the end of the decade. Melius analyst Ben Reitzes upgraded Micron to a buy and forecasted roughly 41% upside over the next 12 months. The rally is being driven by AI-related demand for High Bandwidth Memory (HBM), which uses DRAM stacked alongside advanced GPUs from Nvidia and AMD, creating a general-purpose DRAM shortage and rapidly rising memory prices. Micron, Samsung and SK Hynix have prioritized DRAM supply for HBM, and buyers (hyperscalers and chip designers such as Broadcom) are signing longer-term contracts. Market data cited in the piece shows strong quarter-over-quarter DRAM growth, and Gartner warned higher memory costs will raise PC prices. Micron is pursuing major NAND and fab expansions, including a $24 billion Singapore NAND build and new U.S. fabs in New York and Idaho.
Sustained memory demand and supply shifts affect AI data-center capacity, component pricing, long-term supply contracts and large capital investments by major memory producers—impacting technology infrastructure and downstream hardware costs.

Micron Soars 62% Amid Memory Shortage and AI Demand
Micron Technology has rallied strongly—tripling in 2025 and rising about 62% year-to-date in 2026—driven by heavy demand for memory used in Nvidia AI GPUs and resulting shortages. The company’s market capitalization climbed to roughly $520 billion, surpassing Oracle. Micron will report fiscal second-quarter results after the close Wednesday, with analysts (LSEG) expecting about 148% year-over-year revenue growth. Nvidia’s GTC commentary projecting roughly $1 trillion in orders for Blackwell and Vera Rubin systems through 2027, and comments from industry analysts and vendors, underscore sustained demand for high-bandwidth memory (HBM4e) and rising DRAM prices. Supply constraints have pushed blended DRAM pricing sharply higher and prompted cloud providers and hardware customers to increase capex forecasts.
Micron Stock Surges on Memory Chip Rally
Micron Technology's shares jumped sharply in early May 2026 as a global memory-chip shortage and rising demand tied to the AI buildout pushed semiconductor stocks higher. Micron rose more than 15% on Friday, gained nearly 38% for the week and has climbed about 84% over the past month, lifting its market capitalization above $840 billion, per LSEG. The rally reflects broader strength across chipmakers including AMD, Intel, Samsung and SK Hynix, and is driven by hyperscaler capital expenditures boosting demand for DRAM, NAND, CPUs and storage. Analysts and research firms cited widening prices and margins for memory makers and increased retail investor interest in Micron as contributors to the move.
Memory Makers Eye AI‑Driven 'Supercycle'
Analysts say memory chip demand is morphing into a multi‑year "supercycle" driven by accelerating AI adoption, boosting pricing power and profit forecasts for memory suppliers. Traders pushed shares sharply higher over the past week—Micron surged nearly 38% while the Roundhill Memory ETF rose over 30%—as constrained DRAM and NAND supplies tightened. Samsung Electronics moved up construction of a new Pyeongtaek mega‑fab (P5 Fab 2) by six months to begin in July, and SK Hynix is reportedly receiving investment interest from large tech firms to expand production. Forecasts warn memory prices could climb substantially in 2026, increasing upstream margins for manufacturers while squeezing downstream hyperscaler and device‑maker costs.
