SanDisk shares have surged more than 3,000% [1] over the past 12 months, triggering widespread speculation that the company may initiate a stock split.
This growth reflects a critical shift in the hardware market as artificial intelligence requires massive amounts of high-performance data storage. The surge places SanDisk at the center of the AI infrastructure boom, where the ability to store and retrieve vast datasets is a primary bottleneck for scaling large language models.
Traded on the NASDAQ exchange in the U.S., the company has seen its valuation climb rapidly from a July 2026 price of approximately $40 per share [2]. While some reports indicate the one-year gain exceeds 3,000% [1], other data suggests a surge of more than 2,000% [3] during the same period.
More recent data shows the momentum has continued into this year. SanDisk shares rose 574% year-to-date as of the July 22 close [4]. This trajectory is largely attributed to strong pricing in the sector and an intensified demand for NAND flash storage, the technology used in solid-state drives that power AI data centers [1], [3].
Investors are now watching for a stock split, a common corporate action used to lower the price of individual shares to make them more accessible to retail traders. A split does not change the company's fundamental value but often follows the kind of exponential growth SanDisk has experienced over the last year.
As a subsidiary of Western Digital Corp., SanDisk's performance is closely tied to the broader semiconductor cycle. The current demand for high-performance storage suggests that the AI-driven appetite for hardware is not limited to processing chips but extends deeply into the storage layer of the tech stack.

The dramatic rise in SanDisk's valuation signals that the market is pricing in a long-term structural shift in data storage. As AI applications move from training to inference, the requirement for high-speed, high-capacity NAND flash becomes a mandatory utility rather than a luxury, potentially decoupling storage stocks from traditional consumer electronics cycles.
