Which storage and memory companies are best positioned in the AI wave

1. SanDisk (flash and enterprise SSDs)

Recently spun off from Western Digital and now a stand-alone flash memory company.

It has become one of the top-performing S&P 500 stocks in 2026 on strong AI demand and tight supply dynamics for NAND flash memory. Citi analysts have raised earnings forecasts and price targets on robust fundamentals tied to data centre and AI infrastructure build-outs. 

2. Memory and advanced DRAM/HBM suppliers (Micron, Samsung, SK Hynix)

These firms produce high-bandwidth memory (HBM) and DRAM needed for AI accelerators and large models.

Micron in particular has been highlighted by analysts for potential significant earnings growth driven by AI memory demand and tight supply. 

While Samsung and SK Hynix are not publicly listed in the US, they are key global leaders in memory technologies that support AI workloads.

3. Seagate Technology

Beneficiary of massive scalable storage demand as AI training and inference workloads require vast volumes of cold and nearline storage.

Analysts have seen strong forecasts for data centre storage revenue and some upgrades from brokers. 

4. Western Digital

Focused on enterprise and data centre HDDs, benefiting from large scale storage deployments.

Recently received a neutral analyst outlook that highlighted solid demand but also noted valuation and balance-sheet considerations, implying both upside potential and risk. 

5. Emerging peers and niche suppliers

Smaller flash controllers and component firms such as Phison and niche memory suppliers can participate indirectly via OEM relationships for SSDs and NVMe products. This could add incremental exposure to the AI storage demand trend, though with higher risk and more cyclicality.

Will the storage sector see another round of gains?

Bullish structural thesis

AI data centre build-outs continue to expand exponentially, increasing demand for both flash memory (fast tier) and mass storage (capacity tier). 

Tight global NAND and memory supply has underpinned pricing power and earnings growth for key players. 

The sector has shed some of its traditional cyclical label as investors price in long-term structural demand rather than short-term inventory cycles. 

Risks and caution points

Memory and storage stocks have run extremely hard, in some cases outperforming broader markets by significant margins. This raises the possibility of valuation compression if growth expectations temper. 

Forecast pullbacks or increased volatility around earnings remain possible, especially for companies with less diversified product lines or weaker balance sheets. 

Broader macro factors such as slowing capex cycles, inventory corrections or broader market rotations can affect performance even in structurally positive sectors.

Sector outlook

While near-term pullbacks or consolidations are plausible, the structural demand drivers of AI infrastructure (data centres, cloud expansion, generative AI workflows) suggest the storage and memory sector could sustain further gains over a multi-quarter horizon, particularly for companies with differentiated technology, strong pricing power and diversified end markets.

Summary

Better positioned companies in the AI wave

SanDisk for flash/NAND and enterprise SSD growth

Micron, Samsung, SK Hynix for memory technologies (HBM/DRAM)

Seagate Technology for mass storage demand

Western Digital for enterprise HDD capacity

Market outlook

Structural growth from AI data centre build-outs remains supportive of additional gains, but valuation risk and earnings volatility warrant careful stock-specific analysis and realistic expectations. Portfolio diversification and risk management should remain priorities.
