Sandisk’s shares have surged 568% in 2026, following a 4,300% rally since its February 2025 spin-off from Western Digital, making it the Nasdaq-100’s top performer this year. The company’s stock began trading at roughly $35 per share and has since outpaced broader market gains amid a supply-demand imbalance in the artificial intelligence (AI) memory sector.
The rally reflects surging demand from hyperscalers including Microsoft, Amazon, Alphabet, Meta Platforms, and Oracle, which have allocated over $700 billion in capital expenditures for 2026. SemiAnalysis estimates that 30% of this spending is directed toward memory solutions, with Sandisk positioned to benefit through its NAND flash and enterprise solid-state drive (SSD) offerings. The company’s data center segment reported trailing sales of $5.2 billion, a 437% increase over the prior year, as its products are optimized for inference workloads and data storage.
Long-term supply agreements further underpin Sandisk’s growth trajectory. The company has secured eight contracts with data center and edge customers, covering half of its fiscal 2027 bit supply and two-thirds of fiscal 2028. These agreements, with a weighted-average duration of four years, guarantee a minimum of $93.9 billion in contracted revenue at floor pricing, providing unprecedented visibility in an industry historically characterized by short-term contracts and volatile pricing.
Sandisk has also prioritized capital returns, executing $4.5 billion in share repurchases during the fourth quarter and authorizing an additional $15.5 billion buyback program. A joint venture with Japanese memory specialist Kioxia has enabled the company to minimize capital expenditures as a percentage of sales, allowing greater focus on refining existing chip architectures rather than expanding manufacturing capacity.
The combination of AI-driven demand, long-term supply visibility, and strategic financial management has driven Sandisk’s rapid ascent, leaving investors to assess whether the rally has peaked or if further gains remain.
