Briefly
- Sandisk shares have surged 3,314% prior to now yr, from $32.11 to over $1,096, powered by a worldwide NAND flash scarcity and accelerating AI infrastructure spending.
- Per Sandisk’s earnings launch, Q3 FY2026 income hit $5.95 billion—up 251% yr over yr—with gross margins increasing from 22.5% to 78.4% in a single yr.
- NAND flash costs rose 60% in Q1 2026 and are projected to leap one other 70–75% in Q2, with provide anticipated to stay tight by way of 2028.
You understand a inventory is having a second when it begins outperforming Bitcoin on a year-over-year foundation.
Sandisk, which trades publicly as SNDK, has surged from $32.11 to over $1,096 prior to now yr—a achieve of three,314%. That is not a typo. The corporate that put a USB stick in your laptop computer bag is now one of the spectacular momentum tales in semiconductor historical past.
The inventory is up almost 500% in 2026 alone.

So what occurred? Three issues broke in Sandisk’s favor at virtually precisely the identical time, and collectively, they turned a storage firm into an AI infrastructure play.
The spinoff no one totally priced in
Sandisk spent almost a decade buried inside Western Digital. Western Digital accomplished its $19 billion acquisition of Sandisk in Could 2016, aiming to construct a storage titan straddling each exhausting disk drives and NAND flash reminiscence drives. As an alternative, the 2 companies fought one another for capital for years. Activist traders, led by Elliott Administration, finally had sufficient. The board agreed.
On February 24, 2025, Sandisk accomplished its tax-free spinoff from Western Digital and relisted on Nasdaq beneath its personal ticker. Western Digital shareholders obtained one share of SNDK for each three shares of Western Digital held. The spinoff freed Sandisk to function as a pure-play NAND flash firm—no exhausting disk drag, no conglomerate low cost.
The timing was virtually absurdly good. Sandisk went public simply because the NAND business was clawing out of one in all its worst down-cycles in historical past—a interval when oversupply crashed NAND costs by as a lot as 60% and pushed each main producer into loss territory. The one means from there was up.
AI is hungry, and NAND is the meals
Coaching and operating AI fashions does not simply want compute. It wants storage. Plenty of it. And the AI infrastructure buildout—which Nvidia CEO Jensen Huang has referred to as “the biggest infrastructure buildout in human historical past,” is consuming NAND flash at a tempo the market by no means anticipated.
On-device AI in smartphones and PCs requires ever-larger native storage. As units get extra succesful, the outcomes they produce additionally are inclined to occupy extra reminiscence: extra megapixels, bigger AI fashions, AI generations with extra decision, excessive constancy songs, 4k and even 8k decision films, and so forth.
Market analysis agency TrendForce expects the 128GB Android configuration to fade by the top of 2026 as handsets want extra room for native AI processing. The demand shock hit from each course without delay.
In the meantime, the availability aspect did not sustain. NAND costs rose 60% in Q1 2026, with projections of ending 2026 with a 234% improve per Gartner’s estimations cited by Motley Idiot. Provide is predicted to stay constrained by way of 2028.
AI is inflicting a chip scarcity on a scale corresponding to what Bitcoin miners did just a few years in the past—possible much more so.
Sandisk, as one in all solely a handful of firms working large-scale NAND operations—together with its three way partnership with Kioxia in Japan—is sitting instantly within the path of that pricing wave. Per Sandisk’s SEC submitting, gross margins expanded from 22.5% to 78.4% in a single yr. That form of growth in a commodity {hardware} enterprise is virtually extraordinary.
The numbers usually are not regular
Sandisk’s fiscal Q3 2026 outcomes, per the corporate’s earnings launch on April 30, had been the form of report that reshapes analyst fashions. Income got here in at $5.95 billion, “up 97% sequentially and above the steerage vary,” as Sandisk explains. Datacenter income hit $1.47 billion, up 645% yr over yr. Non-GAAP EPS got here in at $23.41, towards a consensus estimate of $14.66, per Investing.com.
CEO David Goeckeler referred to as the outcomes “a elementary inflection level for Sandisk.”
This fall steerage landed at $7.75–$8.25 billion in income with non-GAAP gross margin of 79–81%, per the identical launch. That is extra income in a single quarter than most semiconductor firms see in a complete yr.
And all the pieces appears to be working in favor of Sandisk.
The corporate retired $650 million in long-term debt final quarter, leaving it with zero long-term debt, and licensed a share buyback program, per 24/7 Wall St. It then joined the Nasdaq-100 on April, changing Atlassian, forcing passive index funds to soak up shares into their holdings on prime of an already parabolic chart.
It’s additionally closing huge multi-year provide agreements with companions that the corporate qualifies as “higher-value prospects.”
In earnings-call language, meaning hyperscalers. So, if Nvidia is the de facto computing supplier of the AI house, Sandisk needs to turn into its de facto storage supplier. The duty will not be as simple—Nvidia’s CUDA know-how provides it a bonus that locks builders in its ecosystem—however can be not unattainable to attain.
The danger price contemplating
The Sandisk rally, although, could also be overheating. The value-to-earnings ratio sits at 41x trailing earnings, properly above Sandisk’s five-year median of 15.74x. Some merchants could also be rotating positive aspects out of SNDK into different names, a possible momentum-exhaustion sign. The NAND cycle has been catastrophically incorrect in each instructions earlier than, and it might activate a provide ramp or a slowdown in AI capital expenditure.
For its half, Google has pledged as much as $185 billion in AI infrastructure spending in 2026 alone. Meta instantly cited rising reminiscence pricing as the first driver of its elevated capital-expenditure steerage, whereas Microsoft attributed roughly $25 billion of its $190 billion 2026 capex to rising element prices, per CNBC. The hyperscalers aren’t slowing down.
Sandisk, backed by its long-running Kioxia three way partnership, 5 multiyear buyer provide agreements carrying greater than $11 billion of economic ensures, and a BiCS8 3D NAND structure with a roadmap geared toward AI-inference reminiscence bottlenecks, is among the cleanest NAND/flash pure-plays on the reminiscence aspect of the AI commerce.
Its This fall income steerage of $7.75 billion to $8.25 billion implies an annualized run price above $30 billion—outstanding for a corporation that re-entered public buying and selling a yr in the past at round ten bucks per share.
