Micron and SanDisk have ranked among 2026's best-performing chip stocks, powered by AI data-center demand for high-bandwidth memory and enterprise flash storage — though both have retreated from all-time highs reached in June.
As of early August 2026, SanDisk was up roughly 574% year-to-date, according to Forbes — among the strongest gains in the S&P 500 this year. Other tallies put the 2026 advance closer to 490%, reflecting the stock's volatility. SanDisk has traded independently only since February 24, 2025, when it was spun out of Western Digital at a debut price near $52. It reached a 52-week intraday high around $2,354 on June 22 before falling more than 30%.
Micron closed at $877.57 on August 7, 2026, down from a record close of $1,213.37 on June 25. Over the trailing 12 months the stock is up about 609%. Shares sold off in July as investors reassessed valuations across AI-hardware names.
The gains reflect an unusually tight memory market. AI servers consume large volumes of high-bandwidth DRAM, Micron's specialty, and enterprise NAND flash SSDs, where SanDisk competes; supply discipline has sustained some of the strongest pricing in years.
Both stocks remain well off their summer peaks, and figures move daily; percentage gains cited are year-to-date as of the dates noted.
