SanDisk stock hit a new 52-week high of $2,191.69 on June 18, 2026, as a tightening NAND flash shortage and surging artificial intelligence data center demand lifted the memory storage maker to record valuations. The stock briefly touched an intraday peak of $2,189.68 on June 16, capping a staggering multi-month rally that has made SanDisk the standout beneficiary of the AI infrastructure build-out.
The NAND shortage is intensifying across the industry. According to the Astute Group, NAND flash prices have more than doubled within months as rapid capacity shifts redirect production toward AI-focused memory products. The International Data Corporation projects 2026 NAND supply growth at just 17 percent year-over-year, well below historical norms, while analysts at Unibetter estimate the shortage will likely persist until 2027 or 2028 as new fabrication capacity gradually comes online.
SanDisk is benefiting from both sides of the supply squeeze. AI hyperscalers and data center operators are locking in long-term contracts for NAND storage at sharply higher prices to secure supply in a constrained market. The company reported Q3 fiscal 2026 revenue of $5.95 billion, reflecting a 97 percent sequential increase, driven by overwhelming AI demand for enterprise storage solutions. Seeking Alpha noted that SanDisk posted record margins in the same quarter, a direct result of NAND price increases and the company’s ability to pass those gains through to customers.
Analysts attribute the shortage to a fundamental structural shift. According to CNBC, NAND is experiencing a similar surge in demand as AI servers require increasing amounts of data storage for model training and inference. The Phison CEO warned in February that the acute shortage of DRAM and NAND flash memory could force many consumer electronics companies to shut down or exit product lines by the end of 2026, underscoring the severity of the supply crunch.
SanDisk’s stock has surged over 4,100 percent in the past year since its February 2025 spinoff from Western Digital, making it one of the most extreme rallies in market history. The company’s position as an independent NAND supplier to AI infrastructure has proved far more valuable than investors initially priced in. With the shortage expected to extend well into 2027, the supply-demand imbalance that has fueled SanDisk’s stock price appears likely to persist.
