Sandisk (NASDAQ: SNDK) stock has rocketed 2,800% higher over the past year as demand for the company's memory processors has spiked, with tech companies snatching up swaths of memory for artificial intelligence data centers.
Analysts differ greatly on their price targets for the stock, with some setting it as low as $1,300 and others as high as $3,000 -- with the average about $2,220. But they overwhelmingly agree on one thing: Sandisk stock is a buy.

Here's why analysts disagree on Sandisk's price target, yet still believe this memory stock is a smart long-term bet.
One of the main reasons analysts differ on their Sandisk price targets is that it's difficult to know how long the current NAND memory shortage will last.
The rise in demand for memory has led tech companies to buy up as much memory as possible, resulting in a shortage. This shortage has, in turn, pushed up gross profit across many memory companies, causing earnings to skyrocket.
But not everyone is convinced this is a long-term trend. Morningstar Chief Market Strategist David Sekera said recently: "I still think it's more of a commodity-oriented product. At some point, supply is going to catch up, and when that happens, look out below."
Sandisk's gross margin was nearly 85% in Q4 of fiscal 2026 (ended July 3) -- up from just 26.4% in the year-ago quarter -- and its non-GAAP earnings spiked to $39.25 per share, up from just $0.29 in the year-ago quarter.
Some of the more bullish analysts believe the memory shortage will last several more years, potentially driving earnings higher for longer.
For example, J.P. Morgan analyst Harlan Sur said Sandisk's latest quarterly results, "suggest a viable path toward stronger earnings power, dampened cyclicality, and more durable fundamentals."
It's not surprising that analysts have different views on how long the memory crunch will be and what it means for Sandisk.
Technology companies are spending an unprecedented amount of money on artificial intelligence data centers -- at least $750 billion in capital expenditures this year alone -- and there appears to be no end in sight for the spending. Alphabet just raised its capex spending target to up to $205 billion for this year and said it'll probably spend more in 2027.
It's also unclear how much data center capacity will be needed for advanced AI models and other AI services. Nearly every tech company is adding artificial intelligence features to their software, which requires computing power that didn't exist just a few years ago.
A handful of analysts lowered their price targets after Sandisk's management issued first-quarter revenue guidance of about $10.5 billion, at the midpoint, below the consensus average of $10.8 billion.
What's clear, though, is that Sandisk is benefiting from this unprecedented AI boom, and that analysts overwhelmingly -- 13 of 16 analysts -- rate Sandisk stock as a buy.
And in general, most estimates anticipate that memory demand will remain elevated for several more years. Management at Micron Technology, a memory company, said recently, "We expect tight conditions to persist beyond calendar 2027 as a result of AI-driven demand across all segments coupled with structural supply constraints."
And leadership at memory manufacturer SK Hynix said earlier this year that the memory shortage will persist through 2030.
Sandisk stock has a trailing price-to-earnings ratio of about 42, compared to the tech sector P/E ratio of 34, so investors are paying for a bit of a premium right now, but not by much.
With Sandisk stock down about 47% from its all-time high, and with memory demand likely to remain elevated thanks to AI, now could be a good time to buy the stock.

Four leading AI models discuss this article
"Current 42x P/E on unsustainable 85% gross margins sets up for a sharp de-rating once supply catches up, regardless of AI tailwinds."
The 2,800% run in SNDK (actually Western Digital, ticker WDC) is classic AI-memory froth. A 42x trailing P/E on 85% gross margins that were 26% a year ago screams mean-reversion risk. The article correctly flags the wide $1,300–$3,050 target dispersion but buries that guidance already missed consensus and that NAND remains a cyclical commodity. Micron and SK Hynix commentary on 2027–2030 tightness is self-serving; history shows every prior shortage ended in brutal oversupply. Alphabet’s $205B capex helps, yet gross-margin compression is already baked into forward models.
If AI training clusters keep doubling every 9–12 months and structural supply stays constrained through 2030 as SK Hynix claims, SNDK could sustain 60%+ margins far longer than bears expect, easily justifying the high-end $3,000 targets.
"The current 85% gross margin is a peak-cycle anomaly that invites competitive capacity expansion, making the stock's current valuation highly vulnerable to mean reversion."
The 2,800% run in SNDK is a classic symptom of a super-cycle in commodity memory, but the 85% gross margin is the real red flag, not a badge of honor. In the semiconductor industry, such extreme profitability inevitably triggers massive capital expenditure from competitors, leading to a supply glut. While AI demand is structural, the market is pricing in perpetual scarcity. A forward P/E of 42 is dangerous for a cyclical hardware player; if revenue guidance misses again, the multiple contraction will be brutal. Investors are confusing a cyclical peak for a permanent shift in the company's competitive moat.
If AI infrastructure spending is truly non-discretionary and supply is constrained by physical lithography limits rather than just capital, the 'commodity' label may no longer apply, justifying a permanent valuation re-rating.
"Sandisk's 85% gross margin is a cyclical peak masquerading as a new normal, and the stock is priced for supply constraints that are already being engineered away."
The article conflates analyst disagreement with fundamental uncertainty, but the real issue is margin sustainability. Sandisk's gross margin jumped from 26.4% to 85% in one year — that's not a durable competitive advantage, it's a pricing power windfall from scarcity. The article cites SK Hynix predicting shortage through 2030, but supply-side capacity additions are already ramping (Samsung, TSMC, Intel all expanding). A 42x trailing P/E on cyclical memory hardware assumes this cycle lasts years; history suggests memory cycles compress faster than expected. The 47% drawdown from highs is presented as a buying opportunity, but could signal institutional recognition that margins are peaking.
If AI capex truly sustains at $750B+ annually and data center buildouts require 3-5 years of heavy memory procurement, Sandisk's current earnings power could persist longer than historical cycles — making the premium valuation defensible and the drawdown a genuine entry point.
"Even with AI-driven demand, NAND memory cycles are volatile; an earlier-than-expected supply ramp or a demand cooldown could erode Sandisk's margins and trigger a sharper multiple compression than this article assumes."
The article leans into a seemingly perpetual AI-driven NAND upcycle to justify a buy, but it soft-pedals the memory cycle risk and sustainability questions around 85% gross margins. NAND pricing, supply additions by rivals, and capex-driven demand shifts can flip quickly; a supply ramp or softer AI demand could compress margins and invite multiple re-rating. The implied ‘several more years’ of tight memory is plausible yet unproven, and the stock’s 42x trailing P/E looks rich for a commodity-like product with pronounced cyclicality. The piece glosses potential negatives, which are exactly the risks investors should stress-test against a bullish thesis.
The strongest counter: memory cycles are volatile; even with AI demand, supply responses and price erosion could come faster than expected, crushing margins and triggering a sharp re-rate.
"Enterprise mix shift may make current margins more durable than historical memory cycles suggest."
All four of you treat the 85% gross margin as a temporary windfall, yet none flagged that Western Digital’s enterprise SSD mix has permanently shifted from consumer NAND. If data-center attach rates stay above 65% of revenue, this isn’t classic cyclicality; it’s a structural re-rating. The real unmentioned risk is whether enterprise customers will accept 40-50% price hikes in the next downturn.
"Extreme margins in commodity hardware are inherently unsustainable because they trigger aggressive competitive supply responses that force price normalization."
Grok, your 'structural re-rating' thesis ignores the physical reality of NAND fabrication. Even if enterprise SSDs dominate the mix, the underlying technology remains subject to Moore's Law and aggressive yield improvements. If Western Digital maintains 85% margins, they are essentially inviting a price war from Samsung and SK Hynix, who have deeper balance sheets to endure margin compression. Enterprise customers won't tolerate 50% price hikes when cheaper, high-density alternatives inevitably hit the market.
"Contract lock-in and demand velocity matter more than theoretical price-war capacity for determining margin persistence."
Gemini's price-war logic assumes symmetrical competitive response, but misses a critical asymmetry: if AI capex truly stays $750B+ annually and hyperscalers lock in multi-year contracts at current prices, Western Digital captures margin lock-in that Samsung and SK Hynix can't undercut without destroying their own datacenter revenue. The question isn't whether cheaper NAND *eventually* exists—it's whether demand velocity outpaces supply additions for 3-5 years. That timeline determines whether enterprise customers face price hikes or abundance.
"Capex-driven moats in NAND aren’t durable; capacity ramps and demand shifts can erode margins and trigger faster re-rating."
Claude’s moat thesis hinges on AI capex lock-in, but I doubt it’s durable. Multi-year contracts can be renegotiated as aux capacity pours in or demand slows; suppliers aren’t immune to margin compression. Even with enterprise SSD mix, NAND pricing power remains contingent on raw supply/demand balance and yield improvements. If 2026–2030 capacity additions outpace AI-driven demand, the so-called moat could erode faster than anticipated, pressuring those 85% margins.
The panelists generally agree that Western Digital's (WDC) 2,800% run is unsustainable due to its high P/E ratio, cyclical nature, and potential margin compression. They caution against assuming perpetual scarcity and AI-driven demand will sustain the current high gross margins.
