πΎ SanDisk at $851: AI Storage's New Pricing Era or Peak Supercycle?
Most people still think of SanDisk as the little USB drive in their desk drawer.
The market has a very different view now.
SNDK soared 9.05% to $851.57 on April 10, touching an intraday high of $855 to set a fresh all-time record. That extends one of the most extraordinary runs in semiconductor history. From a post-spinoff panic low of $27.89 on April 7, 2025, the stock has returned 30x in exactly twelve months. A $10,000 position at last year's low is worth $305,500 today.
MU followed, climbing 3.63% to $421.51 for a third consecutive session with a cumulative 14% gain.
The storage bull run is accelerating. Here is everything behind it, and the critical question: how much further can it go?
π The New SanDisk You Need to Understand
This is not the thumb drive company anymore.
SanDisk separated from Western Digital in February 2025 and relisted as a pure-play NAND flash and enterprise SSD business. CEO David Goeckeler, who built WD into a storage powerhouse, moved with it, a strong signal of where he saw the opportunity. Since then the company has executed a near-complete identity transformation.
The business now sits at the intersection of two powerful forces: a structural global NAND flash shortage and an insatiable AI data centre buildout.
Three products driving the thesis:
The 256TB Enterprise SSD launched in early 2026 is currently the world's highest-capacity enterprise drive, replacing entire racks of hard drives in data centres. It is fully allocated well into 2026, giving SanDisk direct pricing power.
High Bandwidth Flash, or HBF, co-developed with SK Hynix, is the wildcard. It targets 8 to 16 times the capacity of HBM at comparable bandwidth. If it ships on schedule in H2 2026, it opens a product category that sits between bulk NAND and premium HBM memory. Every training and inference server shipping after 2027 could require it. The AI accelerator market has not priced this in yet.
BiCS8 3D NAND, the latest architecture from SanDisk and joint venture partner Kioxia, extends their manufacturing leadership. A first 500-layer announcement is expected by late 2026.
π The Numbers Behind the Rally
SanDisk's fiscal Q2 2026 results reset expectations for the entire year. Revenue hit $3.03 billion, up 61% year on year and 31% sequentially. Data centre revenue specifically jumped 76% year on year to $440 million. Gross margins expanded to 50.9%, up from the low-20s just a year ago. Net income hit $803 million for the quarter, a 617% sequential increase. The company projects data centre exabyte growth in the high-60% range for 2026.
The NAND shortage story is structural, not cyclical. AI workloads including checkpoint storage for trillion-parameter training runs, KV-cache overflow for long-context inference, and retrieval-augmented generation pipelines collided with a NAND bit-supply base that was under-invested for two years. 2026 NAND bit demand growth is running at 20 to 22%, against bit supply growth of just 15 to 17%. The shortage is widening even as capex ramps. CFO Luis Visoso has stated that customer demand is expected to exceed supply well beyond calendar year 2026.
Margin trajectory is just as important. Gross margins reached 30.1% for full year 2025 and are projected to hit 65 to 67% in Q3 2026 as the product mix shifts decisively toward high-margin enterprise SSDs.
π― What Analysts Are Saying
Bernstein raised its target to $1,250 from $1,000 on April 8, naming SNDK its top short-term pick. Analyst Mark Newman's base case applies 11x to an average EPS estimate of $114 across fiscal 2026 to 2029. For fiscal 2027 alone, he models $144 per share. In a bull scenario where NAND prices rise 75% in each of the next two quarters, he models $224 in fiscal 2027 EPS with a blue-sky valuation above $3,000.
Cantor Fitzgerald raised to $1,000 from $800, maintaining Overweight. Morgan Stanley added SNDK as a top pick for H2 2026.
Overall Wall Street sentiment: 11 Buy ratings, 3 Holds, zero Sells. Average consensus target sits at $771, which is now below the stock price following the record run. Bernstein's $1,250 target represents 47% upside from current levels.
π Bull Case vs π» Bear Case
The Bull Case
The NAND shortage is widening into 2027. SanDisk is the only pure-play NAND producer among the top five globally, giving it the cleanest earnings leverage to rising prices. Gross margins at 65 to 67% in Q3 would be exceptional for a hardware company. HBF represents an entirely new product category that the buy side has not fully modelled yet. Q3 earnings on April 30 could reset analyst targets higher again. Bernstein's base case of $1,250 is not unreasonable if NAND pricing holds.
The Bear Case
Memory cycles turn fast. SanDisk's trailing 12-month EPS still shows a $7.49 per share loss from the earlier part of the cycle. Competitors including Samsung, Micron, SK Hynix, and Kioxia are all ramping capacity aggressively. If supply catches up to demand faster than expected in 2027, pricing reverses hard. The stock carries a beta of 2.85, meaning it will amplify any macro risk-off move. Earlier this year the stock pulled back 19% in a single week when Google unveiled TurboQuant, a memory compression algorithm that spooked NAND investors. Any similar headline risk is amplified at this valuation.
Google's TurboQuant reaction showed exactly how sensitive SNDK is to any narrative that threatens AI storage demand. The company also has meaningful exposure to Kioxia JV operations, which could be disrupted by tightening China export controls on advanced NAND.
ποΈ The Trade Setup
The next critical data point is April 30 earnings. Bernstein's base estimate is $14.18 EPS for fiscal Q3, slightly above the $13.99 consensus and the guidance midpoint of $12 to $14. A beat and guidance raise on April 30 would likely push the stock toward $900 to $950 and trigger another round of analyst target upgrades.
If NAND pricing commentary softens or hyperscaler qualification timelines slip, expect a sharp pullback given the stock's 2.85 beta.
For MU, the read-through is clear. NAND pricing tailwinds benefit the entire memory complex. MU's 14% cumulative gain over three sessions is the market pricing in the same structural demand story at a lower pure-play premium. MU reports in June.
The storage bull run is not a meme. It is demand-driven, margin-confirmed, and institutionally owned. But at $851 with a 30x twelve-month gain already in the bag, the easy money is gone. What remains is a bet on whether the NAND supercycle deepens further or whether supply catches up faster than Bernstein's models suggest.
April 30 decides the next leg.
