S&P 500 · Storage · Nearline HDD leader (48%)
Western Digital
The No.1 in nearline exabytes at 48% (NAND spun off as SanDisk). 2025 cloud revenue $3B (+48%), with cloud 87-89% of revenue. It shipped 199EB of nearline (+37%); its 2026 production is sold out to AI-datacenter customers, with deals to top hyperscalers into 2027-28. Up 280% in 2025, the No.3 in the S&P. A core of the AI storage supercycle.

YTD as of 2026-07-10 · source: Yahoo Finance
WD's thesis is oligopoly leverage on the AI-datacenter storage supercycle. After spinning off NAND as SanDisk, it became a pure nearline-HDD player, and since HDD remains the lowest-cost bulk storage, hyperscaler demand is structural — cloud is 87-89% of sales, nearline shipped 199EB (+37%), 2026 output is sold out, and top customers are contracted into 2027-28 for unusual visibility. The HAMR and glass-substrate (HOYA) transition extends the capacity roadmap. Risks are hyperscaler capex swings and QLC SSD encroaching on bulk. Graph propagation: Microsoft/Meta hyperscaler capex pulls demand directly, while upstream HOYA glass-substrate supply is the ramp bottleneck.
