Prediction market bans three candidates for betting on own races

Kalshi barred three political candidates from its prediction market for five years after finding that each had wagered on contests tied to their own campaigns, a move that puts a sharper edge on the fast-growing fight over election betting. The company said the cases amounted to “political insider trading,” a label that underscores how campaign incentives and financial self-interest can collide when candidates are allowed to trade on their own odds.

The candidates were Mark Moran, a former Democratic Virginia Senate candidate now running as an independent; Minnesota state Sen. Matt Klein, a Democrat running in the primary for Minnesota’s 2nd Congressional District; and Ezekiel Enriquez, a Republican who ran in the primary for Texas’s 21st Congressional District. Kalshi said Moran was fined $6,229.30, Klein $539.85 and Enriquez $784.20.

Moran’s case was the most openly defiant. He said on X that he knowingly bet about $100 on himself because he wanted to get caught and draw attention to Kalshi. He also told NOTUS that he wanted to test the company’s enforcement and believed elections could be bought off prediction markets. Kalshi said Moran traded in two markets related to his campaign, including one on people who would run for office in 2026 and another after he publicly entered the Virginia Senate race.

Klein took a different approach. He admitted placing a $50 bet on himself and apologized, saying the episode showed the need for clearer rules and regulations for prediction markets. Enriquez agreed to the fine and the five-year suspension without the public defiance that marked Moran’s response.

Kalshi’s enforcement chief, Bobby DeNault, said the company had recently released safeguards designed to block political candidates from trading on their own elections. The company’s action fits into a broader campaign by Kalshi and rival Polymarket to stop insiders from using election markets for personal gain, as both platforms face pressure to show they can police abuse before it spreads further.

That pressure is already building in Washington, where Congress and the Commodity Futures Trading Commission are watching prediction markets more closely as companies open more investigations. One Reuters-linked report said Kalshi had opened nearly 200 insider-trading cases earlier in 2026. The sanctions against Moran, Klein and Enriquez suggest the industry is moving from novelty to enforcement, but also that the basic rules around political gambling are still trying to catch up with the market itself.
