In the quiet aftermath of its separation from Western Digital, Sandisk has become an unlikely emblem of the AI infrastructure era — a company whose mundane-sounding product, flash storage, has been pulled into the gravitational field of a technological transformation it did not initiate but now cannot escape. Its shares have risen thirtyfold in roughly a year, yet analysts argue the market has not yet reckoned with what nearly $94 billion in committed contracts actually means for a business once defined by cyclical volatility.

Sandisk's AI-Driven Rally May Be Just Beginning Despite 3,110% Surge
Nearly $94 billion in locked-in revenue, priced like a downcycle
Mark
So Sandisk has gone up 3,000 percent in a year. At what point does a stock just get too expensive to chase?
Mimi
That's the instinct, but the valuation math here is actually inverted. The stock is up dramatically, but it's trading at a forward P/E of 7. Nvidia was never that cheap during its early AI phase.
Luke
Hold on. Forward P/E of 7 assumes earnings estimates that are already baked in. Are those estimates based on the $91 billion in contracts, or are they more conservative?
Mimi
The contracts are real. Eight major customers, five-year terms, locked-in volumes. That's not speculative.
Mark
But memory is cyclical. Doesn't that risk still exist?
Mimi
It does, but these contracts have floors and ceilings. They convert what used to be a cyclical business into something with predictable revenue. It's like Nvidia locking in GPU orders years in advance.
Luke
The comparison to Nvidia is useful, but Nvidia was selling the thing everyone needed most. Is storage the constraint in AI infrastructure, or is it still chips?
Mimi
It's both now. You can't run inference at scale without fast storage for model weights and cache. The hyperscalers realized this after they'd already bought all the GPUs.
Mark
So Sandisk is benefiting from a second wave of capex?
Mimi
Exactly. First wave was GPUs. Second wave is everything downstream—storage, networking, power. Sandisk is in the middle of that.
Luke
The data center business grew 437 percent. That's real. But is that growth sustainable, or is it a catch-up from being undersupplied?
Mimi
Some of it is catch-up. But the contracts run four to five years. If they're signing now, they're expecting sustained demand.
Mark
What could go wrong?
Luke
AI capex could slow. A recession could hit. Or the hyperscalers could build their own storage solutions. Those are real risks, and the market isn't pricing them in because the stock is so cheap.
Le Pouls
- Sandisk's data center revenue exploded 437% year-over-year to $5.2 billion, a growth rate that mirrors Nvidia's earliest and most explosive phase of AI-driven expansion.
- The company's $91.1 billion in long-term customer contracts — some running five years or more — has structurally transformed what was once a boom-and-bust memory business into a stream of predictable, committed demand.
- Despite a 3,110% surge in share price since its February 2025 spinoff, Sandisk trades at a forward P/E near 7, a fraction of what Nvidia commanded during a comparable growth phase, creating a striking valuation gap.
- The tension in the market is palpable: a stock that has already risen thirtyfold is simultaneously being priced as though a downcycle is the most likely outcome, even as hyperscalers continue locking in multi-year storage commitments.
- The trajectory now depends on whether the market re-rates Sandisk's multiple to reflect its contracted revenue base — a moment that, if it arrives, could define the next chapter of the AI infrastructure trade.
In the quiet aftermath of its separation from Western Digital, Sandisk has become an unlikely emblem of the AI infrastructure era — a company whose mundane-sounding product, flash storage, has been pulled into the gravitational field of a technological transformation it did not initiate but now cannot escape. Its shares have risen thirtyfold in roughly a year, yet analysts argue the market has not yet reckoned with what nearly $94 billion in committed contracts actually means for a business once defined by cyclical volatility. The deeper question is not whether Sandisk has risen too far, but whether the world has yet understood what it has become.
Sandisk's rise over the past year has been so steep that the ascent itself has become the central narrative. Spun off from Western Digital in February 2025, the company has seen its shares climb roughly thirtyfold, gaining more than 500 percent in 2026 alone — even after retreating about a third from a June peak. The question now is whether that move has run its course, or whether a single figure — $93.9 billion — suggests otherwise.
When Sandisk became independent, it returned to its roots: manufacturing NAND flash storage and solid-state drives for data centers, consumer edge devices, and branded storage products. The transformation came not from its structure but from what its customers began demanding. Training and running large language models requires vast, high-speed storage for data lakes, model weights, and inference caches. AI hyperscalers, having secured their GPU supply, began spending aggressively on storage — triggering what analysts are calling a memory supercycle.
The fiscal year ended July 3 captured this shift in full. Sandisk posted $20.2 billion in revenue, up 175 percent year-over-year, swinging from a prior-year loss to $73.76 in GAAP earnings per share. The data center segment led the charge, jumping 437 percent to $5.2 billion — nearly doubling quarter-over-quarter and rising more than twelvefold from a year prior. Edge devices grew 195 percent to $12.2 billion, lifted by AI-enabled phones and computers. Consumer storage, the smallest segment, rose a modest 29 percent.
The growth arc echoes Nvidia's early AI breakout, when its data center revenue rose 217 percent in fiscal 2024 before compounding further. Sandisk's absolute numbers are smaller — hyperscalers prioritized GPUs first — but the percentage trajectory is strikingly similar, suggesting the company may be in an earlier phase of a comparable cycle.
What sets Sandisk apart is the architecture of its customer relationships. It has signed long-term agreements with eight major data center and edge customers, locking in committed storage volumes with fixed and variable pricing over terms averaging more than four years. Remaining performance obligations stood at $59.8 billion at quarter-end, climbing to $91.1 billion after two additional agreements were signed. These contracts do for Sandisk what chip architecture launches did for Nvidia — they convert cyclical exposure into years of visible, committed revenue.
And yet the market has not priced this in. Sandisk trades at roughly 20 times trailing earnings and a forward multiple near 7 — far below the 30 to 50-plus forward P/E Nvidia sustained during its own breakout years. A company compounding data center revenue at Nvidia-like rates, with nearly $94 billion in minimum contracted demand, is being valued as though a downturn is the base case. That gap between what the contracts imply and what the multiple reflects may be the most important signal the stock is sending right now.
Sandisk's stock price has climbed so steeply over the past year that the climb itself has become the story. The company, spun off from Western Digital in February 2025, has seen its shares rise roughly thirtyfold. In 2026 alone, they've gained more than 500 percent, even after sliding about a third from their June peak. The question investors are asking now is whether this move has exhausted itself, or whether there's still room to run. The answer may hinge on a single figure: $93.9 billion.
When Sandisk became independent, it returned to its core business—making NAND flash storage and solid-state drives for three markets: data centers, consumer edge devices like phones and PCs, and branded consumer storage products. On paper, this sounds unremarkable. The real shift came not from the company's structure but from what its customers started doing with the storage it makes. Training and deploying large language models requires far more than just GPUs. These systems need high-speed storage for data lakes, model weights, and cache as inference deployments scale. AI hyperscalers began expanding their capital spending downstream, beyond chips, creating what analysts describe as a supercycle in memory.
The numbers tell the story with precision. For the fiscal year ended July 3, Sandisk generated $20.2 billion in revenue, up 175 percent year over year. The company posted $73.76 in GAAP earnings per share after reporting a loss the prior year. But the real signal lies in where that revenue came from. The data center business jumped 437 percent to $5.2 billion. In the fourth quarter alone, data center revenue nearly doubled from the prior quarter and was up more than twelvefold from a year ago. Edge devices—the second-largest segment—grew 195 percent to $12.2 billion, driven by AI-enabled phones and computers consuming more flash storage. Consumer storage, the smallest segment, grew a modest 29 percent to $2.9 billion.
This growth trajectory mirrors something investors have seen before. During Nvidia's fiscal 2024, the company's data center revenue rose 217 percent to $47.5 billion. The following year, it grew 142 percent to about $115 billion. Sandisk's data center business is smaller in absolute dollars, which makes sense—hyperscalers prioritized GPU procurement first. But the percentage gains are already in the same neighborhood as Nvidia's early breakout. That comparison matters because it suggests Sandisk may be in an earlier phase of a similar cycle.
What distinguishes Sandisk's position is the structure of its customer commitments. The company has signed New Business Model agreements with eight data center and edge customers. These contracts lock in committed volumes of storage and mix fixed and variable pricing with floors and ceilings. They run as long as five years, with a weighted average term exceeding four years. At the end of the fourth quarter, Sandisk had $59.8 billion in remaining performance obligations. After accounting for two agreements signed after quarter-end, that figure climbed to $91.1 billion. These contracts do for Sandisk what new chip architecture announcements used to do for Nvidia—they convert historically cyclical price swings into years of visible, committed demand. The hyperscalers lined up for Nvidia's Hopper and Blackwell architectures. Sandisk's customers have lined up for storage, and the commitment is locked in.
Yet the stock market has not priced this in. Sandisk trades at a price-to-earnings ratio around 20, with a forward multiple hovering near 7. Nvidia, during its early AI breakout in fiscal 2024 and 2025, never traded this cheaply on a forward basis. Its forward P/E initially spiked to around 30 but eventually sustained above 50 as the company captured the bulk of the initial AI infrastructure build-out. A company whose data center business is compounding at Nvidia-like rates and that has nearly $94 billion in minimum contracted revenue is being priced as if a downcycle is the base case. That disconnect is the tell. Sandisk's stock price has had a spectacular year, but its valuation multiple has not yet had its moment. If the revenue mix continues shifting toward data centers, expansion in Sandisk's multiples should follow.
