NEW YORK, July 28, 2026, 13:59 EDT
- Dell traded 10.1% lower at $383.72 during the open U.S. session.
- Super Micro Computer NASDAQ:SMCI fell 5.2% to $28.27.
- An Evercore estimate implies three customers could represent 25% of Dell’s total annual revenue.
Dell Technologies shares fell 10.1% in afternoon trading on Tuesday. Investors weighed a broad chip selloff and fresh questions about customer concentration. U.S. regular trading remained open.
The slide followed a 2.4% decline on Monday. The S&P 500 had gained 0.02% that day. Dell’s cumulative two-session loss reached about 12.3% by Tuesday afternoon.
Amit Daryanani of Evercore NYSE:EVR estimates three customers could generate $42 billion of Dell’s fiscal 2027 AI-server revenue. That would equal 70% of the company’s $60 billion target.
Those customers are CoreWeave NASDAQ:CRWV, SpaceX’s NASDAQ:SPCX SpaceXAI unit and IREN NASDAQ:IREN.
The $42 billion estimate equals 25.1% of Dell’s $167 billion group-revenue midpoint. That ratio is a calculation, not company guidance. It puts customer mix beside growth as a key valuation test.
The concern arrived after a remarkable run. Dell had gained 242% during 2026 through Sunday, according to Motley Fool.
Broader pressure added force. The Philadelphia semiconductor index was down 3.5% at midday. The S&P 500 gained 0.36%, while the Nasdaq was nearly unchanged.
“Investors are becoming less willing to reward higher AI spending on its own,” Edward Jones analyst Brian Therien said. They now want evidence of returns. Reuters
The comparison pairs afternoon prices with the latest company disclosures. Super Micro’s figures remain unaudited preliminary estimates.
| Measure | Dell | Super Micro |
|---|---|---|
| Afternoon share move | $383.72, down 10.1% | $28.27, down 5.2% |
| AI demand marker | $60 billion FY27 revenue forecast | More than $60 billion of Q4 orders, preliminary |
| Main disclosure issue | Evercore estimate: 70% from three customers | Preliminary Q4 revenue near low end of $11 billion–$12.5 billion range |
| Market value | $251.8 billion | $19.6 billion |
Dell’s underlying operating data still shows exceptional demand. First-quarter AI-server revenue reached $16.1 billion, up 757%. AI orders totaled $24.4 billion, while operating cash flow reached $4.1 billion.
Chief Operating Officer Jeff Clarke said the AI opportunity “shows no signs of slowing.” Dell expects AI-server revenue to rise 144% this fiscal year. SEC
Yet the three-customer estimate exceeds Dell’s entire AI-server business last year. The company’s growth guidance implies fiscal 2026 revenue near $24.6 billion. Three projected customers would equal about 1.7 times that amount.
Daryanani retained a bullish rating and a $500 price target. He called Dell “one of the biggest” equipment-maker beneficiaries of AI infrastructure spending. TipRanks
Super Micro’s July 21 update presented a different mix. Preliminary fourth-quarter revenue was expected near the low end of its range. Preliminary gross margin was estimated at 15% to 17%, well above earlier guidance.
The company reported more than $60 billion of new quarterly orders. However, it warned that some may not represent firm commitments. Orders can also face cancellations or delays.
A regulatory overhang added pressure. Taiwan prosecutors detained a suspect during an investigation into alleged restricted server exports to China. Local media identified the suspect as an Nvidia NASDAQ:NVDA employee, but Nvidia did not confirm that employment.
Risks remain substantial. Dell’s estimated concentration increases exposure to customer funding and deployment schedules. Super Micro’s preliminary figures may change, while its export-control review could affect forecasts.
The next test comes from major technology buyers reporting later this week. Their results will show whether heavy AI spending is producing returns. Super Micro reports final fourth-quarter results on August 11.
