The rally came after Nvidia CEO Jensen Huang spoke at CES 2026 on Monday. Huang described the data storage market as “completely unserved” and predicted it could become the largest storage market in the world.
The comments triggered a sector-wide rally across data storage stocks. Western Digital shares rose 16.8%, while Micron climbed 10%. Seagate Technology Holdings gained nearly 14%.
Morgan Stanley projects NAND flash memory prices will rise 30% to 35% in the first quarter of 2026. NAND flash serves as a key component for long-term data storage and forms the core of SanDisk’s product portfolio.
Earlier this week, Korea Economic Daily reported Samsung Electronics and SK Hynix were seeking 60% to 70% price increases for server DRAM in Q1 compared to Q4 2024. The tight supply and surging demand stem from AI training and inferencing needs.
Bank of America analysts led by Wamsi Mohan identified SanDisk and other memory companies as “key beneficiaries” of the push for AI inferencing and edge computing in 2026. The firm expects organizations to retain more data for training, analytics, and compliance purposes.
Storage demand is “skyrocketing in tandem” with growing use in drones, surveillance, vehicles, and sports technology, Mohan wrote in a January 4 note.
SanDisk became independent in February 2025 after Western Digital spun off its flash storage business. The stock surged more than 500% in 2025, making it one of the top performers in the S&P 500.
SanDisk shares are already up over 40% year to date after just three trading sessions. The stock has soared more than 1,080% since hitting a low on April 22, 2025.
Wall Street analysts maintain a Strong Buy rating on SNDK stock. Eleven analysts rate it as a Buy, while three have Hold ratings. The recent rally has pushed SanDisk above its average price target of $259.83, implying roughly 26% downside from current levels.
