Shares of Dell Technologies plummeted 11% on Wednesday, dragging down other data center equipment makers as fears mounted that enterprise spending on artificial intelligence will not justify the current AI buildout. Hewlett-Packard Enterprise, Oracle and Super Micro also declined. Oracle dropped 9% and is now down 33% for the year, while neocloud provider CoreWeave plunged 15%, wiping out its gains for 2026.
In a report to clients on Wednesday, analysts at Barclays downgraded their ratings on Dell, HPE and NetApp to the equivalent of a hold from buy, “after a significant run and on enterprise AI timing.” The downgrade comes after a remarkable year for the sector: Dell has surged more than 300% in 2026, HPE has climbed about 160% and NetApp has doubled.
Barclays said they have not seen a “meaningful AI inflection” in enterprise spending for these companies. Instead, they attributed recent revenue growth to a global memory shortage, noting that infrastructure companies have passed higher memory costs on to customers. “There is growing sentiment about enterprise AI adoption creating a hardware refresh,” the analysts wrote, adding that businesses are typically allocating just 5% of their IT budgets to AI. “We believe the strong enterprise revenues are more of a function of memory costs than a move to enterprise AI at this time.”
The Barclays analysts also found that only about a quarter of total enterprise AI spending goes toward hardware. They warned that normalizing, and eventually declining, memory prices could weigh on infrastructure-related revenue.
The sell-off reflects a broader shift in sentiment toward the AI infrastructure space, partly driven by concerning revenue figures from OpenAI and fears that rising interest rates will make it harder to service the debt financing much of the buildout.
