Shares of SanDisk surged more than 27% in a single trading day following comments from Nvidia’s CEO at the CES electronics show, who described AI-specific storage as a “completely unserved market” and highlighted the industry’s insatiable appetite for high-performance memory. This one-day gain capped off a 43% advance over the first three trading sessions of 2026, building on a remarkable 500% rally throughout 2025. Institutional and retail investors alike piled into the stock as momentum in the data-storage segment vastly outpaced the broader AI hardware sector, where many high-profile names have underperformed so far this year.

The rally reflects a severe supply shortage that has driven NAND flash prices sharply higher. Industry research firm Trendforce forecasts contract pricing increases of between 33% and 38% quarter-over-quarter for solid-state drives in the first quarter, a level not seen in the memory market since the pandemic downturn. SanDisk’s gross margin expanded dramatically last year, and the company reported a margin well above 50% in its most recent quarter. With global data storage needs expected to double by 2029, the current supply-constrained environment positions SanDisk to capture outsized profits for at least the next 12 to 18 months.

In its latest quarterly report, SanDisk generated approximately 2.3 billion in revenue, representing year-over-year growth of 23%. Management reiterated plans to maintain disciplined capital expenditure and highlighted ongoing investments in next-generation 3D NAND technologies. Analysts at Bank of America project that AI inferencing deployments will drive continued demand, forecasting that enterprise spending on memory and storage for AI workloads could increase by more than 40% this year. Investors are now watching SanDisk’s upcoming guidance closely, expecting further margin expansion and a confirmation that order backlogs remain at record highs.

While near-term supply constraints underpin SanDisk’s profit outlook, new capacity additions by major memory suppliers could eventually alleviate shortages, leading to downward pressure on pricing and margins. Additionally, any slowdown in AI infrastructure spending or a broader technology market correction could temper the stock’s momentum. Nevertheless, given the multi-year horizon for global data growth and the company’s leading position in high-performance NAND, many market participants view SanDisk as a core play on the ongoing AI-driven data center build-out.
