Kalshi revealed two insider trading cases on Wednesday, confirming that both cases have been reported to the United States Commodity Futures Trading Commission. The announcement came after public pressure to make the platform transparent about how they address illegal trading activities.
The company reported that they opened 200 investigations into suspicious activities over the last year. Over a dozen of these investigations were escalated into actual cases.
The announcement was intended to demonstrate the platform’s approach to preventing misconduct. The platform uses a strict surveillance system to track any trades that could be linked to material non-public information.
The platform also noted that there was a need for transparency due to an increase in usage of prediction markets. A full internal review is conducted before any investigation is enforced.
Political Candidate Banned After Self-Related Market Wager
The first case of insider trading involved a politician in the United States. He made a bet of $200 that he was going to run for Governor of California in May 2025. He then went ahead to share this information with the public through social media.
The politician’s announcement was then picked up by Kalshi’s Surveillance Department. The politician’s account was frozen immediately after the discovery.
Kalshi explained how this policy was applicable to political candidates. The candidates are allowed to use the platform. They can even use market forecasts during an election.
However, they cannot participate in a market where they are a participant. The platform banned the candidate for five years. They also imposed a fine, which was ten times the initial trade size of the candidate.
The second case involved a trader who was involved in YouTube streaming markets. This trader was identified as Artem Kaptur. He was allegedly involved in video editing, focusing on Mr. Beast content. Kalshi stated that Kaptur’s trades were successful almost every time.
However, they noted that most of these trades were done in markets where the chances were low. Kalshi stated that Kaptur’s trades were successful almost every time.
