President Trump's repeated public endorsements of Dell Technologies have added more than $13 billion to founder Michael Dell's net worth across three trading days — and drawn accusations that the president is violating federal ethics rules.
President Trump urged Americans to "go out and buy a Dell computer" from the Oval Office on July 6, sending shares up 4.4% — the third time this year his public praise of the company coincided with a same-day stock gain.
"The baseline rule is, even if the president is not trading, there should never be an endorsement of a particular company," Richard Painter, who served as chief White House ethics lawyer under President George W. Bush, told Fortune. "That's an endorsement."
Dell shares rose as much as 9% on July 6 before closing at $394.32, adding roughly $4.6 billion to Michael Dell's paper wealth that day alone. Combined with similar surges on Feb. 19 and May 8, the three endorsement days have boosted the Dell founder's net worth by an estimated $13.2 billion, according to Fortune calculations based on closing stock moves. Dell's current net worth stands at $217 billion, making him the world's fifth-richest person, per the Bloomberg Billionaires Index.
The endorsements raise a question that cuts to the core of presidential ethics: whether a sitting president can legally promote a company whose founder has pledged $6.25 billion to the president's namesake investment program for children, and in whose stock the president holds between $5 million and $10 million.
The pattern in question
Trump's financial disclosure, released last week, documented 24 separate Dell Technologies transactions across five accounts — 16 purchases and eight sales dating from late January through mid-November 2025. The buy side of those trades reached as high as $770,000 in value, while sales topped out at roughly $225,000. In the first quarter of 2026, Trump purchased an additional $5.1 million worth of Dell stock, according to his filings.
On Feb. 19, Trump told a crowd in Rome, Georgia, to buy Dell. Shares rose. On May 8, he named Michael and Susan Dell directly at a White House Mother's Day luncheon, crediting their pledge to Trump Accounts. Shares rose again. On July 6, he rang the opening bell from the Oval Office surrounded by Cabinet officials and CEOs, with the Dells standing feet away.
"Go out and buy a Dell computer," Trump said. "We're going to get him that money back one way or the other."
The AI server story vs. the Trump effect
Patrick Moorhead, chief analyst at Moor Insights & Strategy, argued Dell's stock surge has little to do with presidential endorsements. "Once they got attached to the AI trade, and they started selling a ton to the big neoclouds, that's how this whole thing started," he told Fortune, describing a "two-horse race" between Dell and Supermicro for the largest AI server accounts.
Dell's biggest single-day move this year came after earnings: shares jumped 32.8% on May 29, the day after the company reported record quarterly revenue of $43.8 billion, up 88% from a year earlier. AI server revenue reached $16.1 billion in the quarter, with the company raising its full-year expectation to roughly $60 billion. On May 27, the Department of Defense awarded Dell a five-year contract worth up to $9.7 billion to consolidate Microsoft software licensing.
Moorhead said Trump's endorsements likely moved only retail investors, not institutional ones that already invest in Dell because of its fundamentals. "There's a meme that says: 'I just should have listened to Trump,'" he said.
What federal ethics rules say
Painter pointed to federal standards of conduct for executive branch employees that have barred officials from endorsing private companies "for decades" in both Republican and Democratic administrations. He said Trump's endorsement could move the market because investors assume the president knows when Dell is about to land a federal contract.
"Maybe Donald Trump's about to give them a big government contract or he knows that someone's going to give them a big DoD contract, and there must be something going on that I don't know that he does know about this company and its relationship with the federal government," Painter said, describing investors' likely reasoning.
The White House told Fortune that Trump "was rightfully praising the Dells among many other wealthy individuals and corporations" for donating to the Trump Accounts program and described the Dells as "patriots who are generously contributing billions of dollars of their fortune to the Trump Accounts of millions of kids from working-class families." Dell did not respond to a request for comment.
Michael Dell's cultivation of presidential access is not new. He served on the President's Council of Advisors on Science and Technology under George W. Bush and joined a small group of tech CEOs at the White House under Barack Obama. In January 2017, days into Trump's first term, Dell joined the Manufacturing Jobs Initiative and stayed on the council even as other executives broke away after Trump appeared to defend white nationalists in Charlottesville.
The last time a sitting president faced similar questions about endorsing a specific company was during the Trump administration's first term, when his promotion of certain pharmaceutical companies during the Covid-19 pandemic drew criticism from ethics watchdogs. The difference this time: Trump now holds a personal financial stake in the company he is promoting, and the company's founder has committed billions to a program bearing the president's name.
