Sandisk has emerged as the standout performer in the S&P 500 this year, with its shares climbing roughly 90% year to date and hitting an intraday record high on Tuesday. Today’s near 10% gain was the largest in the index, even as broader U.S. markets pulled back due to trade tensions and geopolitical concerns. This rally places Sandisk well ahead of other leading technology names and underscores investor enthusiasm for companies supplying critical hardware to the burgeoning artificial intelligence sector.

Analysts at Citi published a report on Monday boosting Sandisk’s 2026 earnings-per-share estimate from $13.96 to $17.78 and raising their price target from $280 to $490. The firm cited “solid hyperscaler demand supporting higher pricing” for NAND flash memory, driven in part by customer interest in Nvidia’s new AI computing platform. Citi maintained its Buy rating on Sandisk, noting that supply constraints in the NAND market should persist through next year while AI workloads continue to expand storage requirements.

Since spinning off from Western Digital in February 2025, Sandisk stock has surged approximately 1,050%, turning a $100 investment into about $1,150 by mid-January 2026. The company’s latest quarterly results highlight a 26% sequential increase in data-center revenue to $269 million, its fastest-growing segment. With a current market capitalization near $61 billion and gross margins above 29%, Sandisk is leveraging flash-memory shortages to secure higher pricing and capitalize on the AI-driven demand surge.
