A stock overtaking Bitcoin in year-over-year performance signifies a noteworthy moment. SanDisk (SNDK) has skyrocketed from $32.11 to over $1,096 within the last year, marking a staggering 3,314% increase. Once known for its USB drives, it’s now a standout story in semiconductor history with a nearly 500% rise in 2026 alone.
Three key factors aligned simultaneously, transforming SanDisk into an AI infrastructure giant. After almost a decade under Western Digital post their $19 billion acquisition in May 2016, SanDisk emerged as its own entity on February 24, 2025, through a tax-free spinoff and re-listed on Nasdaq. This separation allowed it to focus solely on NAND flash technology without the burdens of hard disk drives.
This strategic move coincided with the industry recovering from an oversupply downturn that saw NAND prices plummet by up to 60%. AI development demands vast storage capabilities, a need amplified by Nvidia’s CEO Jensen Huang who termed this as “the largest infrastructure buildout in human history.” With AI integration into everyday devices requiring more memory for advanced features such as higher-resolution outputs and larger models, demand surged unexpectedly.
Market research from TrendForce predicts the disappearance of 128GB Android configurations by late 2026 due to increased local processing needs. Concurrently, NAND prices soared by 60% in Q1 2026, with expectations of a 234% hike through 2026 per Gartner’s projections cited by Motley Fool. The supply constraints are anticipated to persist until at least 2028.
SanDisk is uniquely positioned within this pricing surge alongside its Kioxia joint venture in Japan. Its SEC filing noted gross margin growth from 22.5% to 78.4% within a year, an extraordinary feat for a commodity business. Fiscal Q3 2026 results were groundbreaking: $5.95 billion in revenue with a 97% sequential increase, datacenter revenue of $1.47 billion (up 645%), and non-GAAP EPS at $23.41 against a consensus estimate of $14.66.
CEO David Goeckeler described these outcomes as “a fundamental inflection point for SanDisk.” The Q4 forecast anticipates $7.75–$8.25 billion in revenue, with gross margins between 79-81%. This performance has led to the retirement of $650 million in long-term debt and a share buyback program. Additionally, the company’s Nasdaq-100 inclusion on April further bolstered its market position.
SanDisk is also securing substantial multi-year agreements with key partners, positioning itself as a potential mainstay in AI storage against Nvidia’s computing dominance. Despite these successes, the stock’s P/E ratio at 41x trailing earnings suggests possible overvaluation compared to its five-year median of 15.74x. Market dynamics could shift rapidly due to supply changes or altered AI investment trends.
Tech giants like Google, Meta, and Microsoft have committed billions towards AI infrastructure, indicating sustained demand. SanDisk’s robust pipeline, including a partnership with Kioxia and agreements exceeding $11 billion in guarantees, alongside its BiCS8 3D NAND architecture, positions it strongly within the AI storage sector. Its Q4 guidance hints at an annualized revenue potential surpassing $30 billion, underscoring a remarkable transformation from a modest public relaunch to a leading market player.
