Polymarket has ended its collaboration with former US Congressman George Santos following a federal investigation into potential insider trading activities. The Department of Justice is probing whether Santos placed a bet on his presence at the State of the Union address on February 24. Prior to the event, Santos publicly affirmed his attendance. However, he later cited travel issues for his absence, triggering suspicions about a wager to the contrary. And kalshi, a competing platform, reported Santos engaged in self-betting, which led to his account being frozen and the case being escalated to federal authorities.

Federal Scrutiny on Prediction Markets
The ongoing investigation into Santos underscores the heightened scrutiny prediction markets are facing, particularly regarding insider trading concerns. Kalshi detected irregular trading patterns involving Santos, leading them to alert the authorities. While Santos has neither confirmed nor denied holding a Kalshi account, his past legal troubles only intensify the interest in this matter. Previously sentenced for felony wire and check fraud, he was granted clemency by President Trump after serving a few months in 2025.
Illinois Introduces Tax on Prediction Markets
In a notable regulatory development, Illinois has followed Kentucky in imposing taxes on prediction market operators. This move is part of a broader fiscal strategy to generate $65 million in revenue under Governor JB Pritzker’s new budget. However, the specifics of the tax percentage remain undisclosed, drawing criticism from both the American Gaming Association and market advocates. The latter argue that such taxes could lead to double taxation, paralleling capital gains taxes on financial trading. This issue reveals a brewing conflict with more than two dozen states contemplating similar regulations.
Kalshi’s Role in Sports Promotions
Kalshi’s influence stretches into the sports promotion arena. A New York City bar, The Jeffery, hedged a Knicks victory promotion using this platform. And the promotional gimmick promised patrons free food and drinks if the Knicks won their first NBA Finals game in 27 years. With a successful wager, The Jeffery sought to mitigate promotional costs. However, the bar has yet to determine whether financial equilibrium was achieved after the event. Kalshi’s Nicolas Hull described these systems as new risk management tools, opening new avenues for small businesses to navigate unpredictable market dynamics.
Upcoming Regulations and Market Reactions
What comes next could shape the future of prediction markets in the U.S. The federal investigation into Santos might set a precedent for how such cases are handled, potentially leading to stricter regulations. Meanwhile, Illinois’s tax measures could face legal challenges, complicating implementation. Both scenarios highlight the ongoing volatility in this nascent industry. A critical vote on these developments is expected during Illinois’s legislative sessions later this year.
