“We can’t have insider trading in these markets.” Prediction market backers have been quick to tout the Van Dyke charges as evidence that the industry and regulators are properly — and forcefully — policing the markets. Dusty Johnson of South Dakota, a Republican on the House Agriculture Committee, said he wants members to “try to come together to all agree on the facts, understand the legal basis for these products and to chart together a course for where we want to go.” CFTC Chair Michael Selig, who has been a major booster of the prediction markets, said in a statement after the Van Dyke charges that he has “been crystal clear that anyone who engages in fraud, manipulation, or insider trading in any of our markets will face the full force of the law.” And the companies themselves have already rolled out various measures intended to thwart insider trading on their platforms. Polymarket, the person added, is currently working to fully roll out its CFTC-regulated exchange and that “the last thing in the world the company wants is to do something that’s going to prevent it from being able to operate fully in the U.S.” Earlier this week, Kalshi, which is regulated by the CFTC, issued five-year bans against three congressional candidates who had traded on their own elections against the exchange’s rules.
