Rep. James Comer launched a formal investigation into Polymarket and Kalshi, two prediction market platforms, over allegations that government employees leveraged classified information for trading profits. The Republican congressman demanded internal records from both platforms' leadership to determine whether federal workers exploited non-public government data for financial gain.
Comer framed the probe as a national security and ethics issue. Government insiders with access to classified intelligence theoretically possess material advantages when predicting election outcomes, policy decisions, or geopolitical events. Prediction markets have exploded in adoption since 2024, with platforms like Polymarket handling billions in volume on contracts tied to U.S. politics and international affairs.
Polymarket operates primarily on the Polygon blockchain and allows users to wager on real-world events with minimal regulatory oversight. Kalshi, built on traditional infrastructure, secured CFTC approval for event contracts but remains tightly restricted. Both platforms attract retail and institutional participants betting on everything from election results to tech CEO succession.
The investigation zeroes in on whether these platforms lack sufficient know-your-customer and anti-money-laundering controls to prevent government employees from participating anonymously. If federal workers used classified briefings to place winning trades, they would violate the Espionage Act alongside insider trading statutes.
Comer's office requested detailed user data, transaction histories, and compliance procedures from both CEOs. The timing matters. Recent election cycles saw massive prediction market volume spikes on platforms like Polymarket, with some trades showing unusual timing correlated to news cycles and policy announcements. The lack of strict identity verification on decentralized platforms creates enforcement gaps.
This probe marks Washington's latest swing at crypto market infrastructure. Unlike previous regulatory focus on fraud and custodial risk, this centers on surveillance and market manipulation by government insiders. Both platforms face pressure to demonstrate robust compliance frameworks or risk stricter congressional action. Kalshi's CFTC approval offers limited protection here. Polymarket operates in grayer legal territory, making it more vulnerable to pushback.
