Western Digital expands buyback by $4 billion as AI drives chip demand

Data storage maker Western Digital said its board has approved an additional $4 billion for share repurchases, citing strong demand for memory chips used in artificial intelligence servers. The announcement pushed shares up about 5% in premarket trading, extending a rally that has already lifted the stock sharply over the past year.

The company said the new authorization adds to an existing buyback program, under which roughly $484 million remained available as of earlier this week. Western Digital shares have surged on expectations that AI-driven data center investment will continue to boost demand for storage products, including hard drives and flash memory.

A global shortage of memory chips has intensified competition for supply, particularly from AI developers and consumer electronics makers. Limited manufacturing capacity and longer lead times have driven prices higher, benefiting suppliers positioned to serve the fast-growing AI server market.

Western Digital recently forecast fiscal third-quarter revenue and profit above Wall Street expectations, pointing to strong sales of storage solutions for AI workloads. Management said the buyback expansion reflects confidence in cash generation and long-term demand trends tied to artificial intelligence infrastructure.

Western Digital and Seagate Surge as AI Infrastructure Demand Fuels Record Gains

Shares of data storage leaders Western Digital and Seagate have skyrocketed this year, outpacing the broader market as global demand for AI-driven infrastructure fuels unprecedented growth in hard drive sales. Both companies’ stocks have surged over 200% in 2025, reaching record highs amid a worldwide scramble to expand data storage capacity for artificial intelligence applications.

Western Digital shares rose more than 11% on Friday after the company forecast second-quarter earnings above Wall Street estimates. Analysts at J.P. Morgan noted that Western Digital has secured purchase orders from five of its largest customers through 2026, signaling strong confidence in sustained AI-related demand.

Seagate, a close rival, also projected revenue and profit above expectations earlier this week, pushing its stock up more than 22%. Both companies are now among the top three performers in the S&P 500 this year, trailing only Robinhood.

Smaller competitor Sandisk, spun off from Western Digital in February, has seen its shares soar fivefold since its debut and was up another 3.6% on Friday ahead of its upcoming earnings report.

The S&P 1500 tech hardware, storage, and peripherals sector—which includes all three companies—has climbed more than 12% this year, hitting an all-time high. As major tech firms like Alphabet, Microsoft, Meta, and Amazon ramp up capital spending on chips and data centers, analysts expect global AI infrastructure investments to reach up to $4 trillion by 2030.
