Sandisk Corp. has emerged as one of the most explosive stocks in the early days of 2026, with a rally that has captured Wall Street’s attention and reshaped expectations for the memory and storage sector. Shares of the company surged as much as 25% on Tuesday, marking their best intraday performance since February and pushing the stock to a fresh record high. The move followed comments from Nvidia Chief Executive Officer Jensen Huang at the CES technology conference, where he underscored the critical — and largely untapped — role of storage in the artificial intelligence boom.
Sandisk’s gains extend far beyond a single trading session. The stock has climbed more than 40% in the first three trading days of the new year and has skyrocketed roughly 1,050% since bottoming out in April 2025. On Tuesday alone, it stood as the best-performing stock in the S&P 500, outpacing peers across the memory and storage ecosystem. Western Digital and Seagate Technology also posted double-digit percentage gains, reflecting renewed enthusiasm for companies tied to data storage infrastructure.
At the heart of the rally are Huang’s remarks about what he described as a massive, underserved market. Speaking at CES, the Nvidia CEO said storage represents “a completely unserved market today,” adding that it could become the largest storage market in the world as it evolves to hold the working memory of artificial intelligence systems. His comments reinforced a growing narrative that AI’s next phase will not be limited to compute power alone, but will increasingly depend on fast, scalable, and affordable memory and storage solutions.
Industry fundamentals appear to support that thesis. According to Bloomberg Intelligence analyst Jake Silverman, tight supply conditions and rising memory prices are already benefiting digital storage companies. The surge in demand is being driven by both AI training and inferencing, which require enormous volumes of data to be stored, accessed, and processed efficiently. Huang’s CES commentary, Silverman noted, suggests that demand for NAND storage will remain strong across Nvidia-powered systems.
Pricing trends add further fuel to the bullish outlook. Memory prices have been climbing steadily, and reports from Korea Economic Daily indicate that Samsung Electronics and SK Hynix are seeking to raise server DRAM prices by as much as 60% to 70% in the first quarter compared with the prior quarter. Such increases signal a supply-demand imbalance that could continue to lift margins across the sector.
Wall Street analysts are increasingly framing Sandisk and its peers as central players in the next leg of the AI investment cycle. Bank of America analysts, led by Wamsi Mohan, recently described memory and storage companies as “key beneficiaries” of the push toward AI inferencing and edge computing in 2026. As organizations retain more data for training, analytics, and regulatory compliance, demand for storage is expected to surge. Mohan highlighted expanding use cases across drones, surveillance systems, vehicles, and sports technology as areas of rapid growth.
While the AI narrative has so far been dominated by capital spending on chips and data centers, analysts argue that the focus is beginning to shift. Looking ahead to 2026 and beyond, AI inferencing — and the storage required to support it — may dominate the next wave of hardware investment. For Sandisk, that shift has already translated into a historic rally, and investors are betting the momentum is far from over.
