TLDRs
- SanDisk rises as AI data center demand tightens NAND supply conditions
- Analysts lift price targets as storage demand outlook strengthens further
- Sector rally continues with Micron and Western Digital also gaining
- AI infrastructure boom reshapes traditional memory market cycle dynamics
SanDisk Corp (NASDAQ: SNDK) extended its rally on Thursday as investors continued to price in the growing impact of artificial intelligence infrastructure spending on global memory markets.
The stock climbed roughly 10% in afternoon trading, reflecting sustained momentum across semiconductor and storage names tied to AI-driven data center expansion.
Shares recently traded around $1,533 after touching intraday highs above $1,538, marking another strong session in a broader rally that has seen storage firms re-rated as core beneficiaries of AI infrastructure rather than cyclical hardware suppliers.
Flash supply remains constrained
The latest move in SanDisk comes as management reiterated that NAND flash supply conditions remain tight and are likely to persist longer than in previous industry cycles. Executives have pointed to structural demand from hyperscale data centers and enterprise AI deployments as key drivers keeping inventories constrained.
During recent investor engagements, company leadership emphasized that traditional memory cycles, often marked by sharp boom-and-bust swings, are being reshaped by sustained AI buildouts. Customers, particularly large cloud operators, are increasingly focused on securing long-term supply commitments rather than short-term pricing.
Analysts lift price outlook
Wall Street sentiment toward SanDisk has strengthened alongside the stock’s surge. Citi notably raised its price target to $2,025, up from $1,300, while maintaining a bullish stance on the company’s positioning within enterprise storage markets.
Analysts broadly argue that demand for high-performance solid-state drives used in AI training and inference workloads is accelerating faster than expected. Out of 26 analysts tracked in recent market data, a large majority maintain buy ratings, underscoring growing confidence in the durability of the current demand cycle.
The company’s recent earnings performance has further reinforced this outlook, with revenue nearly doubling quarter-over-quarter and profitability surging on higher-value data center sales.
Sector-wide memory rally
SanDisk’s gains were mirrored across the broader memory ecosystem. Western Digital, the company’s former parent, advanced, while Micron Technology also posted gains as investors rotated into semiconductor names exposed to AI infrastructure spending.
The sector-wide move highlights a broader market narrative: memory and storage are becoming increasingly central to AI scalability. As model sizes grow and inference workloads expand, demand for NAND-based solutions is rising not just in hyperscale data centers, but also in edge computing and enterprise systems.
AI reshaping storage cycle
Despite the strong momentum, analysts continue to caution that memory markets remain historically volatile. Previous cycles have seen rapid transitions from shortage to oversupply as manufacturers ramp production in response to high prices.
For now, however, AI-related demand is overwhelming supply-side adjustments. Investors are increasingly treating SanDisk not as a traditional semiconductor cyclical, but as a structural AI infrastructure beneficiary.
Unless there is a slowdown in data center capital expenditure or a rapid capacity expansion from competitors, supply tightness is expected to remain a dominant theme supporting pricing and margins across the sector.
