Early on in his second term in office, Donald Trump eased his way into a Tesla and delivered a delighted review to the car’s manufacturer, his biggest billionaire benefactor, Elon Musk.

“Everything is computer!” Trump exclaimed.

This year, the president has brought that philosophy to his investment portfolio. Trump revealed in a series of filings this month that he made nearly 4,000 trades between January and March. That’s 44 per day on average and almost three times more than all of 2025 combined. Total trading volume was between $200 million and $700 million.

Unlike his recent Oval Office predecessors—including himself—Trump isn’t just buying and selling bonds, broad-based index funds and money markets. Scores of individual publicly traded companies are getting the presidential seal of approval or disapproval, making the commander-in-chief something like a one-man market signal.

Every time one of those companies is added to or subtracted from his portfolio, the questions multiply. Does it do business with the government? Does it need regulatory consideration? Does it want export approvals, tax favors, federal contracts, antitrust restraint, White House praise or a seat at the table?

Forbes analyzed the president’s largest stock trades, roughly 240 that were larger than $250,000. The pattern that emerged is clear: All of his 10 best buys were tech company stocks, boosted by the unregulated AI boom Trump has made a centerpiece of his economic policy.

Everything is, indeed, computer.

Trump’s best apparent bet was Dell. The President bought between $1 million and $5 million of Dell shares on February 10; the company’s stock, buoyed by AI data center deals, is up 142% since then. That means that if he bought $3 million of shares, the middle of his declared range, they’d be worth about $7.3 million today.

And Trump did not stop there. He bought the company’s shares three more times, all smaller amounts, in March, then gave the company an unusually convenient bit of presidential pumping on May 8. “Go out and buy a Dell,” he declared from the White House after an event with CEO Michael Dell. The stock closed 11.5% higher that day and is up 31% since.

That’s not the only plumbing-of-the-AI-economy company Trump has........
