Sandisk Stock Is up Nearly 500% in 2026. Q3 Results Show Its Data Center Business Is Still Growing.

Sandisk Corporation (SNDK) is a memory player built for the data-hungry world, designing NAND flash storage that powers everything from consumer devices to hyperscale data centers. But in 2026, it is not just supplying storage. Rather, it is embedded within the artificial intelligence (AI) boom itself. As data-heavy AI workloads scale rapidly, demand for faster, efficient storage is surging, placing the company firmly at the core of this shift.

That positioning has translated into blistering growth. From cloud infrastructure to edge computing, its high-performance storage is seeing strong adoption. The data center segment is leading the charge as AI and cloud spending ramps up, while a richer enterprise customer mix and better pricing continue to strengthen revenue and overall business momentum. Plus, a shift toward long-term supply agreements – Sandisk’s so-called new business models – is bringing more predictability to revenues and margins, quietly strengthening the foundation beneath the growth story.
