SanDisk Corp. shares have delivered one of the most spectacular runs in recent memory, surging past $979 after climbing more than 1,200% since its 2025 spinoff from Western Digital, yet investors now face a classic Wall Street dilemma: is the memory chip maker still a compelling buy at these elevated levels, or has the AI-driven rally priced in too much optimism for 2026 and beyond?
The stock, trading under NASDAQ: **SNDK**, closed at **$979.07** on April 22, up **$75.58** or **8.37%** in a single session amid heavy volume exceeding 15 million shares. That move pushed the company's market capitalization near $145 billion and extended year-to-date gains well beyond 275% in 2026 alone. The rally has been fueled by unrelenting demand for high-capacity NAND flash memory used in AI data centers, where hyperscalers are building massive "data lakes" that require vastly more storage than traditional computing workloads.
