Western Digital WDC shares surged 7% on Monday as investors increased bets on companies positioned to benefit from the accelerating AI-driven memory and storage boom.
The rally in Western Digital comes amid growing optimism around demand for high-capacity data center storage, with investors viewing the company as a key beneficiary of expanding AI infrastructure spending.
Strength across the broader semiconductor and AI ecosystem also supported sentiment.
Investor enthusiasm has been fueled by Western Digital’s strong fiscal third-quarter earnings report and a 20% dividend hike, developments that reinforced confidence in the company’s growth trajectory.
Reports of increased institutional buying have added momentum to the move, as large investors position for continued upside tied to rising AI-related storage demand.
According to TipRanks data, 14 out of 16 analysts currently maintain a buy rating on Western Digital shares.
AI infrastructure demand boosts storage sector
The latest rally reflects broader investor enthusiasm surrounding the AI-memory supercycle, which has been driving demand for storage and memory solutions across the technology sector.
Western Digital has been witnessing strong execution as cloud providers and hyperscalers expand infrastructure to support artificial intelligence workloads.
The company has benefited from increased adoption of high-capacity hard disk drives (HDDs), particularly in the data center market.
As AI and cloud adoption accelerate, companies are requiring larger storage capacities to manage rapidly growing data volumes generated by training models and inference systems.
Western Digital has focused on delivering high-capacity storage products designed to meet those requirements at scale.
Western Digital reported fiscal third-quarter adjusted earnings of $2.72 per share, compared with $1.36 per share in the same period last year, surpassing Wall Street expectations of $2.39 per share.
Revenue rose 45% year-over-year to $3.34 billion, ahead of analysts’ consensus estimate of $3.25 billion.
The results also exceeded the company’s own guidance issued in late January, when Western Digital projected earnings in the range of $2.15 to $2.45 per share and revenue between $3.1 billion and $3.3 billion.
The rally in storage-related stocks has coincided with broader gains in semiconductor companies linked to artificial intelligence infrastructure spending.
Micron and Sandisk also benefit from AI boom
Micron Technology has also emerged as a major beneficiary of AI-related demand trends.
The company has seen strong demand for its high-bandwidth memory (HBM) products, which are increasingly used in AI servers and advanced computing systems.
The growth of AI servers is reshaping the DRAM market because these systems require substantially more memory than traditional servers.
This trend has increased demand for high-capacity DIMMs and low-power server DRAM products.
Micron is expected to deliver revenue and earnings growth of more than 100% each for the current year ending August 2026.
Analysts have also slightly raised earnings estimates for the company over the past week.
Sandisk has similarly gained attention as investors look for exposure to advanced storage technologies tied to AI computing.
The company has benefited from increasing NAND flash storage demand, driven by AI training workloads and inference applications that generate massive amounts of data.
Edge devices supporting on-device AI features are also contributing to rising storage requirements.
Sandisk’s BiCS8 quad-level cell storage product is progressing through qualification with two major hyperscalers.
The company’s extended joint venture agreement with Kioxia Corporation through December 2034 has further strengthened investor confidence in its long-term positioning.
SanDisk’s shares were up 0.2% today, gaining 42% in May so far.
Micron stock surged 6% in the session, rallying 53% in the month.
