Dell stock plunges 11%, leading data center sell-off as fears mount about 'enterprise AI timing'

Dell Technologies shares fell 11% on Wednesday, dragging down other data center equipment names amid growing concerns that enterprise spending on artificial intelligence may not support the current infrastructure buildout. The decline extended to peers in the sector, with Hewlett-Packard Enterprise, Oracle, and Super Micro all joining the downward slide.

The selloff followed a client report from Barclays, where analysts downgraded their ratings on Dell, Hewlett-Packard Enterprise, and NetApp. The firm cited "a significant run and on enterprise AI timing" as the primary reasons for the downgrade. Previously viewed as top performers in the market, these companies had seen substantial gains this year. Dell shares were up more than 300%, Hewlett-Packard Enterprise had jumped approximately 160%, and NetApp had doubled its value.

Sentiment toward the AI infrastructure space has shifted recently, driven partly by concerning revenue figures reported by OpenAI. Broader market fears also center on rising interest rates creating a challenging environment for a buildout heavily reliant on debt. Oracle, identified as a heavy borrower, dropped 9% on Wednesday and is now down 33% for the year. Neocloud provider CoreWeave plunged 15%, wiping out its gains for 2026.

Barclays analysts stated they have not observed a "meaningful AI inflection" in enterprise spending for Dell, Hewlett-Packard Enterprise, or NetApp. Consequently, they lowered the rating on each company to the equivalent of a hold from buy. The analysts attributed increased revenue not to AI adoption, but to the global memory shortage. They noted that infrastructure companies have passed the higher price of memory along to customers.

In their report, the Barclays team wrote that there is growing sentiment that enterprise AI adoption is creating a hardware refresh. However, they added that businesses are typically allocating just 5% of their IT budgets to AI. The analysts concluded that strong enterprise revenues are more of a function of memory costs than a move toward enterprise AI at this time.

Further complicating the outlook for hardware vendors, Barclays found that only about a quarter of total enterprise AI spend is directed towards hardware. The analysts warned that normalizing and eventually declining memory prices could weigh on infrastructure-related revenue.

The memory sector itself is notoriously cyclical. Shares in this space declined this week following weekend reports from China's ChangXin Memory Technologies regarding progress on a new chip structure. Micron shares are down 11% for the week, while South Korea's SK Hynix has tumbled 13% in U.S. trading. Western Digital has dropped more than 8%.
