Western Digital shares surged 282% in 2025, making it the second-best performer in the S&P 500 after completing the spin-off of its flash memory business into the newly independent SanDisk. The separation, executed in the first quarter, allowed investors to value Western Digital’s core hard-disk drive (HDD) operations and legacy storage business on their own merits. At the same time, heightened demand for data storage capacity from artificial intelligence infrastructure build-outs drove severe supply shortages across both HDDs and solid-state drives, lifting Western Digital to multi-year highs. The company’s market capitalization climbed past $XX billion, supported by robust order backlogs and limited channel inventory.

As Western Digital approaches its all-time high levels, analysts highlight a mix of positive momentum and potential headwinds. The ongoing AI spending spree continues to underpin HDD pricing, but industry forecasts warn that supply shortages may ease later in 2026 as new production lines come online. Consensus estimates call for mid-teens revenue growth in fiscal 2026, driven by both enterprise and cloud data center segments. Among 20 analysts covering the stock, the median price target implies approximately 15% upside, reflecting confidence in Western Digital’s leadership in high-capacity HDDs and its expanding reseller network. Investors are advised to monitor channel inventory levels and NAND flash pricing trends to gauge whether current valuations remain justified.
