Western Digital shares jumped 52% in a month as hyperscalers boosted orders for HDD storage amid AI infrastructure expansion.
Western Digital (NASDAQ:WDC) closed at $653.53 on June 15, 2026, capping a 52.38% one-month gain and a 1,085.81% surge over the past year. The company’s market capitalization reached $225.26 billion as it benefited from AI-driven demand for data storage solutions.
After spinning off SanDisk in late 2025, Western Digital refocused on enterprise storage, with cloud revenue accounting for 90% of total sales in Q1 2026. Revenue and margins exceeded expectations, driving shares to record highs before a March geopolitical selloff.
Management highlighted multiyear commitments from hyperscalers, reinforcing Western Digital’s role in the AI storage buildout. The stock’s rally reflects strong execution and sector tailwinds.
