Kalshi CEO Tarek Mansour Warns Insider Trading on Prediction Markets Face DOJ Action

"If you commit insider trading on Kalshi, that can—and will at some point—be a federal crime," Mansour said. "I actually do expect the DOJ to prosecute some of these cases."

The emergence of bad actors such as insider traders is inevitable on prediction markets, according to Tarek Mansour, the co-founder and CEO of Kalshi. But the executive isn’t worried about such behavior sullying his business. “There’s always going to be bad actors. The goal is to just squash them,” Mansour said during an onstage interview at Semafor World Economy in Washington, D.C. yesterday (April 15). He believes cases will be weeded out by Kalshi’s internal investigations and, eventually, by federal prosecutors.
