Western Digital (WDC) Stock Rallies As Micron’s $100 Billion AI Deals Lift Storage Demand - Yahoo Finance

The recent announcement of a $100 billion AI memory deal by Micron Technology has triggered a surge in demand for semiconductor storage, driving up stock prices for companies like Western Digital (WDC... Read original →

Micron’s $100B AI memory commitment signals a structural shift: the AI race is no longer just about compute but storage density and data pipeline throughput. While Micron leads in HBM, Western Digital benefits from the persistent demand for high-capacity CMR/UAMR HDDs and QLC NAND in AI data lakes—enabling a heterogeneous storage stack. Geopolitically, U.S. export controls compel supply chain diversification; WDC’s Malaysia/Thailand fabs mitigate China exposure but lag Samsung in advanced packaging integration. Competitively, SK Hynix may fast-track HBM4, while Kioxia could push co-developed BiCS6 solutions with WDC to win cloud contracts. Over the next 18 months, 'disaggregated storage' architectures will boost storage vendors’ pricing power—but WDC’s premium valuation hinges on fixing cash flow quality, not just riding AI hype.
