You know a stock is having a moment when it starts outperforming Bitcoin on a year-over-year basis.
Sandisk, which trades publicly as SNDK, has surged from $32.11 to over $1,096 in the past year—a gain of 3,314%. That's not a typo. The company that put a USB stick in your laptop bag is now one of the most impressive momentum stories in semiconductor history.
The stock is up nearly 500% in 2026 alone.
So what happened? Three things broke in Sandisk's favor at almost exactly the same time, and together, they turned a storage company into an AI infrastructure play.
The spinoff nobody fully priced in AI is hungry, and NAND is the foodOn-device AI in smartphones and PCs requires ever-larger local storage. As devices get more capable, the results they produce also tend to occupy more memory: more megapixels, larger AI models, AI generations with more resolution, high fidelity songs, 4k and even 8k resolution movies, and so on.
Market research firm TrendForce expects the 128GB Android configuration to vanish by the end of 2026 as handsets need more room for local AI processing. The demand shock hit from every direction at once.
AI is causing a chip shortage on a scale comparable to what Bitcoin miners did a few years ago—likely even more so.
The numbers are not normalCEO David Goeckeler called the results "a fundamental inflection point for Sandisk.”
Q4 guidance landed at $7.75–$8.25 billion in revenue with non-GAAP gross margin of 79–81%, per the same release. That's more revenue in a single quarter than most semiconductor companies see in an entire year.
And everything seems to be working in favor of Sandisk.
It’s also closing big multi-year supply agreements with partners that the company qualifies as “higher-value customers.”
In earnings-call language, that means hyperscalers. So, if Nvidia is the de facto computing provider of the AI space, Sandisk wants to become its de facto storage provider. The task is not as easy—Nvidia’s CUDA technology gives it an advantage that locks developers in its ecosystem—but is also not impossible to achieve.
The risk worth consideringSandisk, backed by its long-running Kioxia joint venture, five multiyear customer supply agreements carrying more than $11 billion of financial guarantees, and a BiCS8 3D NAND architecture with a roadmap aimed at AI-inference memory bottlenecks, is one of the cleanest NAND/flash pure-plays on the memory side of the AI trade.
Its Q4 revenue guidance of $7.75 billion to $8.25 billion implies an annualized run rate above $30 billion—remarkable for a company that re-entered public trading a year ago at around ten bucks per share.
