SouthernWorldwide.com – House lawmakers have initiated an investigation into the prediction market platforms Kalshi and Polymarket, citing concerns over alleged insider trading activities by their users.
The House Oversight Committee announced the probe on Friday. Chairman James Comer of Kentucky has dispatched letters to the CEOs of both Kalshi and Polymarket, Tarek Mansour and Shayne Coplan, respectively. These letters request internal documentation to assess the measures the companies are taking to combat insider trading.
Specifically, Representative Comer is seeking details on how Kalshi and Polymarket investigate potential insider trading incidents. He also wants to understand their identity verification processes for both domestic and international account holders.
Kalshi and Polymarket are platforms that enable users to speculate on the outcomes of future events. These events can range from elections and sports results to geopolitical developments. While these platforms have seen a surge in popularity, they have also attracted the attention of lawmakers.

This scrutiny intensified after a series of bets with suspiciously precise timing raised alarms about potential insider trading. The committee’s investigation is looking into trading activity on these platforms that was linked to the Iran war and the capture of former Venezuelan leader Nicolás Maduro.
A report by data analytics firm Bubblemaps, as highlighted by “60 Minutes,” indicated that nine Polymarket accounts profited significantly by accurately predicting key dates related to the conflict. These accounts collectively earned $2.4 million.
In April, federal prosecutors brought charges against a U.S. special forces soldier. The soldier was accused of using confidential government information to place a bet on Maduro’s removal from office. This particular trade reportedly yielded over $400,000.
The soldier, identified as Gannon Ken Van Dyke, 38, faces charges including unlawful use of confidential government information for personal gain, theft of nonpublic government information, commodities fraud, wire fraud, and making an unlawful monetary transaction. He has pleaded not guilty to these charges.
In response to the allegations, a Polymarket spokesperson stated on Friday that the company “maintains a comprehensive market integrity framework.”
Kalshi also emphasized its commitment to preventing insider trading. Elisabeth Diana, a spokesperson for Kalshi, informed CBS News that the company has implemented “comprehensive” safeguards to address this issue.
In recent months, both platforms have reportedly strengthened their rules. These changes are aimed at preventing users from trading on non-public or confidential information.
In April, Kalshi took action against three congressional candidates. The platform fined them and suspended their accounts for five years. This decision followed an internal investigation that found they had gambled on the outcomes of their own elections. Prediction market platforms like Kalshi now explicitly prohibit members of Congress from creating accounts.
Polymarket introduced a new rule in March that further restricts trading activities. This rule prohibits traders from betting on an event if they hold a position of authority or influence that could potentially affect the outcome of that event.
