- Mark Moran placed bets on his own Senate race across two Kalshi markets in 2025.
- Kalshi’s action signals prediction markets are serious about self-regulation now.
- Two other candidates who cooperated settled for fines under $800 by comparison.
Mark Moran was still weighing a U.S. Senate run when he began placing bets on whether he would enter the race. By the time Kalshi’s surveillance systems caught up with him, he had traded across two separate markets tied to his own candidacy, admitted the trades were improper, then refused to engage further with investigators.
The prediction market exchange fined him $6,229 on Tuesday and banned him from the platform for five years.
A Paper Trail Spanning Two Markets
Kalshi’s disciplinary filing shows Moran placed ten orders in November 2025 on a market tracking potential candidates for public office in 2026. Two months later, on January 21, he announced his candidacy for Virginia’s Democratic Senate primary. Six days after that, he placed two further trades directly on his own nomination odds, then promoted the market on his social media accounts.
Under Kalshi’s CFTC-approved exchange rules, any trader with direct or indirect influence over an event’s outcome is prohibited from trading on markets tied to that event. Moran, as a candidate, qualified as a direct decision maker under that definition on both counts.
Cooperation Divided the Outcomes
Kalshi compliance staff reached Moran by phone the day after flagging the activity. He acknowledged the trades violated platform rules. He then stopped responding entirely.
Two other candidates named in separate enforcement notices published the same day fared better. A Minnesota congressional primary candidate and a Texas Republican primary contender both cooperated immediately, settled their cases, and walked away with fines of $539 and $784 respectively, each receiving the same five-year suspension but avoiding the harsher disciplinary process Moran faced.

Why It Matters For Kalshi
The fines are small. The implications are not. Kalshi probability figures are increasingly cited by newsrooms, campaigns, and analysts tracking political risk, making the integrity of those markets a question that reaches well beyond the platform itself.
A candidate trading on their own race does not simply break a rule. It introduces self-interested noise into data that outside observers treat as signal.
By pursuing public enforcement, naming individuals, and escalating penalties for non-cooperation, Kalshi is staking a claim to something prediction markets have not always been credited with: genuine regulatory seriousness.
“No matter how small the size of the trade, any trade that is found to have violated our exchange rules will be punished,” Kalshi said.
