Prediction Market Platform Kalshi Suspends and Fines Three Congressional Candidates Over Political Insider Trading

The prediction market platform Kalshi announced on Wednesday that it had imposed disciplinary measures against three candidates running for Congress—representing Minnesota, Texas, and Virginia—for engaging in what the company characterized as "political insider trading" by wagering on their own electoral campaigns.

All three candidates received five-year suspensions from the platform. Kalshi stated in an official announcement that the enforcement actions were made possible by "newly implemented safeguards designed to prevent political candidates from trading on their own elections."

The Three Sanctioned Candidates

The disciplinary notices targeted Mark Moran of Virginia, who initially pursued the Democratic primary nomination for U.S. Senate before switching to an independent candidacy; Matt Klein, a Minnesota state senator competing in the Democratic primary for the state's 2nd Congressional District; and Ezekiel Enriquez of Texas, who participated in the Republican primary race for Texas's 21st Congressional District.

Mark Moran's Case

Kalshi documented that Moran engaged in trading across two separate markets connected to his campaign activities. The platform explained that he first placed a wager on himself in a market predicting potential candidates for public office in 2026. Subsequently, after publicly announcing his candidacy for Virginia's Democratic Senate primary, he traded again on his own campaign prospects.

When initially approached by Kalshi investigators, Moran confirmed his candidate status and acknowledged violating platform regulations. However, he later ceased engagement with the company's compliance team. According to Kalshi, "Moran repeatedly refused to resolve this matter via settlement." The company issued Moran a fine of $6,229.30 alongside his suspension.

Moran responded via social media, stating that he had wagered $100 on himself, anticipating the violation and the resulting controversy. He claimed the action was intended to highlight concerns about the company's practices. Moran wrote that as a senator, he would pursue aggressive regulatory action against Kalshi, proposing a 25 percent tax on the company to address the national debt. He also criticized the platform's credibility and regulatory oversight.

Matt Klein and Ezekiel Enriquez

Both Klein and Enriquez demonstrated full cooperation throughout Kalshi's investigation process. Klein admitted to trading a modest sum on his own primary election outcome. He acknowledged the rule violation, agreed to pay a fine of $539.85, and accepted his suspension.

Klein disclosed that in October of the previous year, acquaintances informed him about a prediction market offering wagers on his primary race. Unfamiliar with such platforms, he created an account and wagered $50 of his personal funds on his own victory. Kalshi notified him of the violation in March 2026. Klein characterized the incident as a mistake and issued an apology, adding that the experience underscores the necessity for more transparent regulatory frameworks governing prediction markets.

Enriquez traded a marginally larger amount than Klein—though still less than $100—on his own election. He fully complied with investigators, settled the violation by paying a fine of $784.20, and accepted his suspension from the platform.
