Prediction market platform Kalshi has suspended and fined three congressional candidates—Mark Moran of Virginia, Matt Klein of Minnesota, and Ezekiel Enriquez of Texas—for engaging in what it calls ‘political insider trading’ by betting on their own campaigns ahead of the 2026 midterm primaries.
The enforcement action, announced on Wednesday, marks the most aggressive move yet by a prediction site against political figures, spotlighting growing unease over the integrity of election-related betting. Kalshi’s internal probe revealed that Moran traded in two markets tied to his candidacy, first betting on himself as a potential runner and later after announcing his bid for Virginia’s U.S. Senate seat as a Democratic primary contender before switching to an independent run. He was fined $6,229.30 and banned from the platform for five years.
Klein, running in Minnesota’s 2nd Congressional District Democratic primary, placed a smaller bet on his own election outcome, resulting in a $539.85 fine and a five-year suspension. Enriquez, a Republican primary candidate for Texas’s 21st Congressional District, wagered a slightly larger amount, cooperated with the investigation, and agreed to a $784.20 fine alongside a matching suspension period.
Moran, unapologetic in his response, took to social media to criticize Kalshi. “I traded $100 on myself, knowing this would happen and the attention it would create to highlight how this company is destroying young men,” he stated, vowing to impose a 25% ‘vice tax’ on such platforms if elected to the Senate to help reduce national debt.
The suspensions come amid broader scrutiny of prediction markets, which have ballooned in popularity with platforms like Kalshi and rival Polymarket handling billions in weekly trading volume. Lawmakers from both parties have voiced alarm over potential insider trading risks, especially following high-profile trades tied to sensitive geopolitical events. Bipartisan bills introduced this year aim to bar CFTC-regulated firms from offering election contracts, with Rep. Blake Moore of Utah warning that under-regulated markets expose the U.S. to public safety and national security threats.
Legal ambiguities persist around such trading. While federal laws target breaches of confidentiality, candidates betting on their own races often fall into a gray area, as they owe no duty to keep their own campaign plans secret. Meanwhile, about 40 states contend that prediction platforms resemble gambling and should face state gaming laws, with Arizona recently filing criminal charges against Kalshi for allegedly operating an unlicensed casino—a case temporarily halted by a federal judge.
Kalshi’s head of enforcement, Robert DeNault, emphasized the platform’s stance. “Regardless of the size of a trade, political candidates who can influence a market based on whether they stay in or out of a race violate our rules,” he said.
This isn’t the first enforcement action by Kalshi in 2026. In February, it suspended an employee of YouTube star MrBeast and a minor California gubernatorial candidate for similar self-betting violations. The fines from Wednesday’s actions are expected to be donated to a nonprofit focused on financial market education, consistent with prior penalties totaling over $7,500 across the three candidates.
