The prediction market platform imposed five-year bans and fines on a state senator and two congressional candidates. One politician said he broke the rules intentionally to expose corruption.
Prediction market platform Kalshi has taken disciplinary action against three US politicians. Minnesota State Senator Matt Klein, congressional candidate Ezekiel Enriquez, and Virginia Senate candidate Mark Moran placed bets on the outcomes of their own election races. All three received five-year platform bans and fines.

Klein was fined $539, Enriquez $784. Moran received a $6,229 fine and must return his trading profits. Kalshi explained that the stricter penalty for Moran stemmed from his refusal to cooperate during the investigation.

How Politicians Explained Their Actions on Kalshi
Klein stated that he bet $50 out of curiosity to understand how prediction markets work. He later learned that his action violated platform rules. Notably, Klein is a co-author of a bill in the Minnesota legislature that would impose a complete ban on betting on real-world event outcomes, including elections.
Moran, a participant in the HBO reality show “Fboy Island” and a former investment banker, stated that he made his bet intentionally.
“I wanted to get caught,” he wrote on X. “After discovering potential manipulation on Polymarket, I realized how filled with corruption Kalshi is.”

In his post, Moran also promised that if elected to the Senate, he would impose a 25% “sin tax” on the platform.
Enriquez, who ran for the House of Representatives from Texas, did not provide comments. Kalshi documents indicate that Klein and Enriquez each purchased contracts worth less than $100.
Why Kalshi Penalizes Even $50 Bets
Kalshi Head of Enforcement Bobby DeNault stated that political candidates who can influence the market by their decision to run or not run violate exchange rules regardless of bet size. According to him, these cases did not require referral to the CFTC or Department of Justice.
In February, the platform fined a former California gubernatorial candidate $2,000 and banned him for five years for a similar violation.
Kalshi vs. Insiders
Kalshi and Polymarket remain the dominant platforms in the segment. In March 2026, Kalshi’s trading volume reached approximately $13 billion, while Polymarket’s stood at $10.57 billion.
Both platforms have tightened controls following pressure from lawmakers. Nevertheless, this incident highlights that such platforms cannot yet guarantee the elimination of insider trading, even among public figures.
