NEW YORK, May 26, 2026, 04:13 (EDT)
- Western Digital was quoted at $492.70 in early premarket trading, up 1.74%, after closing Friday at $484.28.
- U.S. markets were closed Monday for Memorial Day; regular Nasdaq trading resumes at 9:30 a.m. Eastern.
- The stock remains tied to investor confidence in artificial intelligence data-center storage demand.
Western Digital shares rose in early premarket trading Tuesday, giving the AI storage trade a fresh test after a long U.S. market weekend. Google Finance showed WDC at $492.70, up 1.74%, after the stock closed Friday at $484.28; Western Digital’s own LSEG-sourced stock lookup put Friday volume at about 4.48 million shares.
The timing matters. Nasdaq listed U.S. markets as closed Monday for Memorial Day, with normal stock-market hours running from 9:30 a.m. to 4 p.m. Eastern and premarket trading from 4 a.m. to 9:30 a.m. Eastern, a thinner session where prices can swing more sharply because fewer shares change hands.
For investors, Western Digital is no longer just a maker of hard-disk drives, or HDDs, the spinning-disk storage used for large amounts of lower-cost data. It has become one way to trade the storage side of the artificial intelligence buildout: the servers may run the models, but the data still has to sit somewhere.
The stock’s last full trading week was uneven. Western Digital fell to a Monday close of $458.68, recovered to $486.46 on Thursday and slipped to $484.28 on Friday, still leaving buyers close to the highs of the recent move rather than back at the week’s lows.
The main support is earnings, not a single premarket print. In its fiscal third quarter, Western Digital reported revenue of $3.34 billion, up 45% from a year earlier, GAAP gross margin of 50.2% and free cash flow of $978 million. For the fiscal fourth quarter, it forecast revenue of $3.65 billion, plus or minus $100 million, and non-GAAP earnings of $3.25 a share, plus or minus 15 cents. Non-GAAP means company-adjusted profit figures that strip out some accounting items; useful, but not the same as official GAAP results.
Chief Executive Irving Tan gave investors the cleanest version of the bull case: “Virtually every AI workload” creates data that is stored persistently and cost-efficiently on HDDs, he said. Chief Financial Officer Kris Sennesael said the business “continues to strengthen,” and pointed to rising momentum across end markets. SEC
Western Digital’s May customer survey pushed the same point. The company said 87% of respondents prioritized capacity expansion and total cost of ownership, meaning the full cost of buying and running infrastructure. Ahmed Shihab, Western Digital’s chief product officer, said AI is “a data systems challenge, not just a compute challenge.” Western Digital Corporation
Competition is still tight and narrow. Seagate remains Western Digital’s closest public HDD peer, while Sandisk, the former Western Digital Flash business, is now separate and no longer consolidated in WDC results. TipRanks reported earlier that Wedbush analyst Matt Bryson raised targets on both Western Digital and Seagate, citing a widening HDD supply-demand gap, while BofA’s Wamsi Mohan also lifted targets and pointed to tight supply as manufacturers held back on capacity expansion.
The broader index backdrop has helped the trade. UBS Global Wealth Management lifted its 2026 year-end S&P 500 target to 7,900 from 7,500, citing resilient consumer spending and demand for data-center infrastructure; Reuters reported that UBS saw much of the earnings-estimate boost coming from semiconductor demand, especially memory-chip pricing, and data-center investment.
Western Digital’s next public checkpoints come quickly. Its investor calendar lists a Bank of America Global Technology Conference appearance on June 2 and an Evercore Global TMT Conference appearance on June 3, giving management another chance to address pricing, supply and order visibility.
But the setup can still bend the other way. Extended-hours strength may fade once regular volume returns, and Western Digital itself lists demand volatility, tariffs and trade restrictions, dependence on a limited number of suppliers, competitive pricing, supply-chain delays, customer concentration risks and international conflicts among factors that could cause results to differ from its outlook.
That leaves Tuesday’s open as the cleaner read. The question is not whether one early quote holds, but whether buyers defend the stock when regular Nasdaq liquidity returns and investors move from holiday-thinned trading back into the full tape.
