Sandisk Shares Gain 800% Since Spinoff as AI Drives NAND Demand

SNDKSNDK

Sandisk stock soared 800% since its February 2025 spinoff, registering a 559% gain in 2025 and a 59% rise year-to-date in 2026. TrendForce forecasts SSD contract prices will climb at least 40% quarter over quarter in Q1 2026 on tight supply and surging AI-driven data center demand.

1. AI Inference Driving Unprecedented NAND Demand

SanDisk’s position in the AI infrastructure supply chain has been turbocharged by the exponential growth of inference workloads. Data center operators are expanding model context windows from 2,048 to 32,000 tokens, a 15× increase that multiplies memory requirements per inference instance. Industry forecasts now project NAND flash demand from AI use cases to grow at a 25% compound annual rate over the next three years, compared with just 8% for traditional storage applications. This structural shift has fueled a three-fold increase in enterprise SSD billings at SanDisk since early 2025, validating the firm’s strategy to prioritize data-center optimized flash products over commodity consumer drives.

2. BiCS8 Node Ramp Unlocks Next-Gen Scalability

The recent ramp of SanDisk’s proprietary BiCS8 232-layer process marks a critical inflection point. Internal benchmarks show BiCS8-based SSDs delivering 45% higher write endurance and 30% faster random read I/O than the prior generation. By collaborating with SK Hynix on co-development of high-bandwidth flash modules, SanDisk expects production capacity for enterprise products using BiCS8 to double by the end of 2026. As data centers iterate on higher compute-to-storage ratios, these enhancements translate directly into lower total cost of ownership, giving SanDisk a competitive edge over peer flash suppliers that remain on 176- or 192-layer nodes.

3. Financial Momentum and Outlook

Since its spin-off in February 2025, SanDisk has outpaced all memory peers with a cumulative revenue increase of 65% and a gross margin expansion of 550 basis points. In Q3 2025, enterprise flash sales accounted for 62% of total revenues, up from 38% a year earlier. Management guided Q4 revenues to grow by 18% sequentially, driven by ramping data-center deployments and an expected 40% quarter-over-quarter increase in module shipments to cloud hyperscalers. With capital expenditures focused on topping up 300,000 wafer starts per month by mid-2026, investors should anticipate sustained double-digit top-line growth through at least fiscal 2027.
