Kalshi bans three US candidates for betting on their own races

Prediction-market operator Kalshi announced it has fined and suspended three U.S. congressional candidates after internal reviews found they placed wagers on the outcomes of races in which they were directly involved. The company said the actions form part of new safeguards designed to prevent political insider trading on its platform.

Kalshi’s disciplinary filings named Matt Klein, a Minnesota state senator running for Congress, Mark Moran, an independent Senate candidate in Virginia, and Ezekiel Enriquez, who ran in a Texas Republican primary. According to the company, Klein and Enriquez placed relatively small bets (Klein’s was about $50), while Moran acknowledged a $100 wager and declined a settlement that would have required a public statement, drawing a larger fine. All three received five-year suspensions.

The enforcement action arrives amid heightened scrutiny of prediction markets after several high-profile, large-dollar trades earlier this year drew attention to potential market abuse and the platforms’ influence on public discourse. Regulators and state authorities have increasingly questioned whether event-based exchanges should face gambling-style restrictions or be regulated as commodity exchanges, a debate that has intensified since 2024.

Beyond the platform-level penalties, the episode has prompted state-level responses and legislative attention. Some states have moved to restrict government employees or officials from participating in event betting, and executives at Kalshi have publicly signaled that federal enforcement and oversight—principally by the Commodity Futures Trading Commission—will be central to policing bad actors on such platforms. The interplay between state bans and federal jurisdiction remains a live legal and policy issue.

Market analysts and policy observers say the Kalshi enforcement could accelerate tighter platform compliance, more rigorous customer screening, and new statutory proposals targeting insider trading on prediction markets. For operators, the near-term priority will likely be demonstrable monitoring and transparency to assuage regulators and participants; for lawmakers, the event strengthens the case for clearer rules that balance legitimate hedging and research uses against corruption and market manipulation risks.
