Donald Trump has made any number of bad bets over the years: Casinos, airlines, hotels and an ill-fated “university” all famously make the list. Thanks to recent disclosures, we now know that his stock portfolio also includes its own cabinet of curiosities.

On February 2, for example, Trump put between $1 million and $5 million into shares of Kura Sushi USA, a conveyor belt sushi chain with 91 U.S. locations across 23 states. That’s a seven figure bet on raw fish from a man whose most reliable culinary conviction has long been that dinner should be fried and served through a drive-thru window with a side of Diet Coke.

Trump may want to stick to what he knows. Kura’s stock is down 18% since then, making KRUS one of Donald Trump’s worst stock purchases of 2026. (A spokesperson for Kura said that the company doesn’t comment on individual investors.)

Last week, Forbes examined 240 of the president’s biggest trades, revealed in a series of filings that showed more than 4,000 transactions in the first three months of the year—44 per day on average and almost three times more than all of 2025 combined. And unlike previous presidents, who largely stuck to conflict-avoidant investments, Trump is deep in the equities markets buying and selling scores of corporate shares. His biggest wins were all tech companies that have made a killing on the AI boom he has thrown the weight of the federal government behind promoting.

But AI giveth and AI taketh away: Some of the worst-performing stocks in the president’s portfolio have been hammered by AI anxiety. Take software makers Workday and Adobe. Trump bought between $1 million and $5 million of each of them on February 10. Both companies are facing concerns that their primary products—HR software and design tools, respectively—might be displaced by generative AI newcomers. Adobe is down 10% and Workday is down almost double that, meaning that if the president bought the middle of their ranges, $3 million, he’d have lost about $900,000 total between the two.

Not every company on this list is down due to Silicon Valley’s latest inventions. The biggest loss—Fidelity National Information........
