Trump Criticizes Prediction Markets After Military Arrest
The integrity issue has been a major concern for critics of prediction markets, particularly in sports event contracts.
However, after a recent military issue, President Donald Trump criticized the prediction market even though it is federally regulated.
Trump critical of federally regulated prediction market platforms
Trump’s criticism of prediction markets followed the arrest of a soldier who allegedly used classified information to profit on Polymarket from a military campaign.
There was a recent White House meeting where a reporter raised the issue. A member of the U.S. military special forces, Army Master Sgt. Gannon Ken Van Dyke, was accused of buying Polymarket contracts on whether Venezuelan President Nicolas Maduro would be captured by Jan. 31, 2026.
Van Dyke aided the plan to capture Maduro and allegedly used classified information when buying Polymarket contracts. The Justice Department stated that Van Dyke spent a little over $33,000 to buy 436,000 contracts, which netted a profit of $404,000, as Maduro and his wife were captured on Jan. 3. Van Dyke bought the contracts between Dec. 30, 2025, and Jan. 2, only a day before Maduro was seized during a U.S. raid.
Before the capture, there were reports of suspicious trading. After profiting, Van Dyke moved the money through a crypto exchange not registered in his name.
Trump’s ties to federally regulated industry
While Trump was critical of prediction markets when asked by the reporter, he was not overly so. He stated, “The whole world, unfortunately, has become somewhat of a casino. You look at what’s going on all over the world, in Europe, and every place they’re doing these betting things. I was never much in favor of it. I don’t like it conceptually, but it is what it is.
"No, I’m not happy with any of that stuff, but they have all these different sites. They have predictive markets. It’s a crazy world.”
However, he stated that he was concerned about insider trading that may be occurring in other military actions, such as the current conflict with Iran.
Trump was a casino owner three decades ago and has ties to the prediction market industry. He owns a majority stake in the social media platform Truth Social, which is planning to expand with a cryptocurrency-based prediction market platform.
Trump’s son, Donald Trump Jr., is a strategic advisor to the two largest prediction market platforms, Kalshi and Polymarket.
The Chairman of the Commodity Futures Trading Commission (CFTC), which regulates the prediction market, is Michael Selig, a Trump nominee. The CFTC has intervened in lawsuits in which states seek to ban prediction markets.
Mounting pressure on issue of vulnerable markets
The prediction market platforms are not only facing pressure from critics about their products overall, but also on specific markets, which are seen as more vulnerable to insider information.
Most of the pressure from critics of vulnerable markets has been for sports event contracts. However, in March, Rahm Emmanual, a potential Democratic candidate for the 2028 presidency, proposed a ban on prediction markets for federal employees and their families across the judicial, legislative, and executive branches.
In dealing with the mounting pressure, Polymarket has worked closely with the sports leagues it is partnered with, including restricting vulnerable markets, such as individual pitch contracts in MLB.
