Kalshi says it has suspended and fined three congressional candidates after detecting what it called political insider trading on their own campaigns, marking one of the clearest signs yet that election prediction markets are moving into a more aggressive compliance phase as their political profile rises.
The enforcement action
The platform said the three candidates were flagged under newly released rules designed to stop political candidates from placing trades tied to their own elections. All three received five-year suspensions, while the financial penalties varied depending on the conduct Kalshi described in its disciplinary notices.

Former Democratic primary candidate for Virginia Senate now running as an independent.

$784.20 fineHow each case unfolded
Kalshi said Mark Moran traded in two separate markets connected to his campaign and later declined to resolve the matter through a settlement. Moran publicly defended his conduct, saying on X that he intentionally placed a small trade on himself in part to draw attention to his broader criticism of prediction markets.
Matt Klein and Ezekiel Enriquez, by contrast, were described by Kalshi as cooperative during the investigation. Klein said he wagered $50 after hearing there was a market on his race and framed it as a first-time mistake. Enriquez was said to have traded slightly more than Klein, though still less than $100.
Prediction markets are now colliding with a basic political reality: candidates often know more about their own campaigns than anyone else.
Why it matters
The episode goes beyond three relatively small fines. It highlights the ethical and regulatory tension at the heart of political prediction markets: if campaigns themselves can trade, the line between speculation and privileged information quickly gets blurry. Even small personal wagers can raise broader questions about market integrity.
Kalshi appears to be trying to show that it is capable of policing those conflicts before regulators do it for them. That matters at a moment when election-related markets are attracting heavier scrutiny from lawmakers, campaigns, and competitors, especially as the platforms seek broader legitimacy in U.S. politics and finance.
