Prediction Market Insiders Arrested in Israel
Several Polymarket insiders were arrested in Israel on Thursday. They included army reservists who used classified information to place trades on Polymarket.
The suspicious trades included an anonymous user betting that Israel would strike Iran on the day it did in June 2025. The Shin Bet confirmed that they had evidence to indict the suspects with “serious security offenses,” “bribery,” and “obstruction of justice.”
Even though the case took place in Israel, it concerns the same issues the CFTC faces on the prediction markets it regulates in the United States.
The CFTC considers whether an inside trader has breached a previous duty, like an exchange employee placing trades at the expense of customers or the company itself. The CFTC’s first insider trading case was against an exchange employee who placed 12 gasoline trades ahead of his employer, profiting at his employer’s expense.
While insider trading cases have traditionally focused on exchanges or their employees misappropriating information, prediction markets have created new insiders. Bad Bunny’s backup dancers would likely be in breach of a previous duty if they disclosed his first song during the Super Bowl. So would a State Department official trading on Venezuela’s collapse ahead of military action against the country.
Whether the CFTC has the bandwidth to police those violations remains an open question.
Selig confident in CFTC’s capacity
On Monday, Barrons reported that the final CFTC enforcement attorney resigned from the agency’s flagship Chicago office. It heightened concerns about the CFTC’s limited capacity to regulate prediction markets that grew rapidly throughout 2025.
CFTC Chairman Michael Selig defended his agency on Bloomberg’s Odd Lots podcast. Selig argued that not only was the agency hiring, but many functions could also be done with AI and other electronic tools. He did not specify what specifically was being done with new technologies in lieu of enforcement lawyers.
Selig’s interview dropped during a fresh wave of skepticism about prediction market protections against insider trading.
Kalshi CEO Grilled over insider trading
Kalshi’s CEO Tarek Mansour appeared on CNBC on Tuesday to discuss prediction markets in the wake of the Super Bowl. The hosts spent much of Mansour’s appearance asking him about insider trading.
Mansour announced new insider trading detection and enforcement tools the previous week. He also listed newhires who would help police Kalshi’s markets.
However, the rapid growth of prediction markets and the confidentiality of CFTC investigations has rattled even large traders. Top 100 Kalshi trader Gaeten Dugas briefly stopped trading in a Spotify market because of an alleged insider.
The CFTC and prediction market exchanges will have to find new ways to maintain trust in the wake of odd price movements as they continue to reach into new spaces.
