Micron and SanDisk Lead 2026 Memory Chip Surge
Micron Technology and SanDisk Inc. have seen massive stock growth driven by AI infrastructure demand, though analysts disagree on the sector's long-term cyclicality.
Memory chip manufacturers Micron Technology and SanDisk Inc. have emerged as top-performing stocks in 2026. SanDisk led the S&P 500 with growth exceeding 600%, while Micron increased by approximately 270%. This surge is driven by the build-out of artificial intelligence infrastructure, creating sustained demand for NAND memory used in data center solid-state drives, as well as DRAM and high-bandwidth memory for AI accelerator chips and GPUs.
Micron has informed investors that market tightness is not expected to ease until after 2027, allowing the company to maintain elevated profit margins as global production struggles to keep pace with demand. Benjamin Reitzes, head of technology research at Melius, suggests that Micron and Advanced Micro Devices (AMD) are positioned to reach $2 trillion market capitalizations, citing computational efficiency gains and the necessity of CPUs in agentic AI architectures.
However, investor Michael Burry warns that the memory sector is headed for a down cycle over the next two years. He argues that pricing power and profit margins will erode as production catches up and Chinese memory capacity increases. Micron is scheduled to report earnings this Wednesday, with FactSet estimates projecting sales of $51.33 billion and earnings of $31.72 per share.
