SanDisk shares surge on soaring AI memory demand and strong NAND pricing.

SanDisk’s first-quarter outlook calls for midpoint revenue of $10.55 billion and non-GAAP diluted earnings of $45 per share, though annualizing that forecast may overstate sustainable earnings if NAND pricing peaks.
Nvidia’s planned $12.9 billion acquisition of Hugging Face involves an open-source AI platform with more than 18 million registered users, 3 million AI models and over 200,000 enterprise customers; Nvidia CEO Jensen Huang said more than half of Nvidia’s revenue is driven largely by open models.
The rally showed signs of short-term technical exhaustion: one-hour RSI reached 74.34 and 15-minute RSI reached 80.97, while a break below the daily pivot at 1,654.57 was identified as an early warning that momentum could be fading.
SanDisk and manufacturing partner Kioxia are pursuing multibillion-dollar investments to expand next-generation fabrication capacity in Japan, as investors focus on storage bottlenecks in AI data centers and the company’s longer-term margin and backlog targets.
Some technology customers have reportedly secured memory capacity through contracts extending to 2031, giving SanDisk greater visibility into future AI-storage demand even as its results remain exposed to NAND pricing and concentration among large customers.
SanDisk shares jumped 11.9% to $1,740 on Friday as investors bet on AI-driven storage demand and strong memory pricing. Yahoo Finance reported the surge was fueled by the company's addition to the S&P 100 index, blockbuster first-quarter results showing 51% sequential revenue growth to $8.965 billion, and expectations that NAND chip shortages will persist.
The rally reflects broader confidence in SanDisk's ability to capitalize on data centers hungry for storage. Recent long-term contracts with major tech customers extend through 2031, signaling strong future demand. Yet analysts warn the stock's momentum shows technical exhaustion — one-hour trading indicators hit 74.34 RSI — and remains vulnerable to NAND price swings.
SanDisk's first-quarter results crushed expectations. Revenue jumped 51% sequentially to $8.965 billion, while gross margin hit 84.6% — nearly double typical semiconductor levels. The company projects Q2 revenue of $10.55 billion midpoint and non-GAAP earnings of $45 per share, signaling sustained momentum ahead.
Tech giants are locking in memory capacity years in advance. Some customers have secured NAND contracts extending to 2031, giving SanDisk rare visibility into future AI demand. Yahoo Finance highlighted that hedge fund ownership of SanDisk more than doubled ahead of its S&P 100 inclusion, reflecting confidence in the storage supercycle.
Nvidia's planned $12.9 billion acquisition of Hugging Face — an open-source AI platform with 18 million users and 3 million models — underscores the scale of AI infrastructure expansion. CEO Jensen Huang noted that over half of Nvidia's revenue now flows from open-source AI models, creating insatiable demand for storage capacity.
SanDisk's promotion to the S&P 100 index triggers automatic buying by passive funds. The company also expanded its stock buyback authorization to $14 billion, signaling management confidence and supporting the stock price. Together, these moves pushed hedge fund ownership higher and broadened retail participation in the rally.
The stock's gains rest on shaky ground. NAND memory prices could collapse if supply recovers faster than expected, crushing margins and earnings. SanDisk also depends on a handful of mega-cap customers for the bulk of its revenue, creating concentration risk that analysts say could unwind quickly.
