The prediction market platform Kalshi fined three political candidates and suspended them from its site after the company said they had bet on their own races.

Kalshi spokesperson Elisabeth Diana confirmed to NOTUS that the three candidates involved were Mark Moran, a candidate for U.S. Senate in Virginia, Matt Klein, a congressional candidate in Minnesota, and former Texas congressional candidate Ezekiel Enriquez.

“Just like in traditional financial markets, bad actors will try to cheat,” Bobby DeNault, the head of enforcement and legal counsel at Kalshi, wrote in a press release Wednesday announcing the action. “Regulated exchanges must constantly evolve and adapt their systems to address insider threats. These three cases are an example of how developing proactive engineering solutions can help identify illicit trading activity.”

All of the candidates were fined various amounts after Kalshi contacted them regarding their trades. Moran, who received the highest fine of $6,229.30, “initially acknowledged being a candidate and violating the rules, but later stopped all communication with our team,” DeNault wrote in the release.

Klein and Enriquez, who were fined $784.20 and $539.85, respectively, both acknowledged their violations and accepted five-year suspensions.

In a statement posted on X, Klein apologized for his wager, calling it a mistake. He said that he had been “curious” about how the prediction market site worked and bet $50 dollars that he would win his primary.

“My experience, like many other Minnesotans, points to the need for clearer rules and regulations for these types of markets,” Klein wrote.

Moran, a former Democratic candidate for Senate who is now running as an independent in a longshot bid to oust incumbent Sen. Mark Warner, told NOTUS that he placed the Kalshi bid in order to generate attention both for his campaign and to test the effectiveness of the company’s enforcement.

“Elections can be entirely bought off prediction markets,” he told NOTUS in an interview, adding that if he is elected, he’d like to strengthen regulation of the nascent industry.

When he met with the Kalshi compliance team in February, Moran said he realized that the team wanted to make its “own press narrative of it.” So he decided to tell his own side of the story.

“This is a great day for me. I mean, my girlfriend’s pissed at me, yelling at me about it, but I’m like, ‘I’ve been waiting for this to happen,’” Moran, who starred on the reality TV show “FBoy Island” and worked as an investment banker, said. “No one was going to report on my ideas before.”

Kalshi said the three candidates had all violated a rule designed to prevent political insider trading. The prediction market site has been the source of scrutiny in recent weeks, as lawmakers decide whether or not to regulate the burgeoning billion-dollar market. Kalshi is valued at $22 billion, according to Bloomberg.

Lawmakers have also been considering ways to prevent insider trading on the platform and its competitor, Polymarket. Kalshi is currently regulated by the Commodity Futures Trading Commission. Michael Selig, who was nominated by Trump in October to lead the agency, withdrew a proposed rule in February aimed at regulating prediction markets.
