Kalshi Adds Disclosure Rules for High-Risk Prediction Markets

Kalshi has rolled out new safeguards for certain prediction markets after concerns about insider trading and manipulation. Under the new rules, traders must disclose their employers before trading in high-risk markets that have been flagged for those issues.

The change matters because prediction markets rely on trust that prices reflect broad market views rather than privileged access or undisclosed conflicts. Requiring employer disclosure gives Kalshi another way to identify potential conflicts when a trader is participating in a market tied to sensitive information.

The policy targets markets considered higher risk, rather than applying the same process to every trade. That distinction suggests Kalshi is focusing additional scrutiny where insider knowledge or manipulation concerns are more likely to arise.

For companies, traders, and observers of the broader prediction market sector, the update highlights a growing governance challenge: how to keep event-based markets open while limiting the influence of participants who may have non-public information.

The safeguards also arrive as prediction markets continue to attract attention from users interested in trading on real-world outcomes. Kalshi’s response shows that market operators are under pressure to strengthen controls as these platforms become more visible.
