Prediction market operator Kalshi said it has taken disciplinary action against two users for insider trading violations, marking the first cases it has publicly identified as part of a broader enforcement effort that has included hundreds of investigations over the past year. The company said the cases involve an editor for YouTube streamer MrBeast and a former California governor candidate, and it has reported both matters to the US Commodity Futures Trading Commission.
Investigations And First Disciplinary Cases
Kalshi said it opened 200 investigations into potential violations of its trading rules over the past year, with more than a dozen becoming what it described as active cases. The company said it suspended the two users accused of violating its rules. Bobby DeNault, who leads Kalshi’s enforcement efforts, said in a post on Wednesday that no financial exchange is immune from bad actors, including stock exchanges, banks, and prediction markets, and said the company is committed to deterring and finding manipulators and those who cheat.
Prediction markets in the United States have grown in popularity, with platforms such as Kalshi and Polymarket allowing users to place wagers on outcomes ranging from sports to politics. The growth has brought increased concern about trades based on inside information. The industry’s leading companies drew hundreds of millions of dollars in wagers on the outcome of the 2024 US presidential election. The sector faced scrutiny from regulators under the Biden administration and has received a warmer reception during the presidency of Donald Trump. Donald Trump Jr, the president’s son, serves in advisory roles at Kalshi and Polymarket.
Case Involving MrBeast Editor
Kalshi disclosed a fine of more than $20,000 and a two year suspension for Artem Kaptur, who the company said placed bets based on material, non public information obtained through his work as a video editor for the YouTube streamer MrBeast. Kalshi said its surveillance systems flagged Kaptur’s trading wins as near perfect and statistically anomalous, and said users on the platform had also alerted the company to the abnormal activity.
A spokesperson for Beast Industries, the entertainment company founded by MrBeast, said the company has no tolerance for the behavior, whether by contestants or employees. The spokesperson said the company has a policy against employees using proprietary information and has started an independent investigation into the incident. The spokesperson said the company welcomes Kalshi and others in the space taking the issue seriously, and added that the effort depends on companies being willing to communicate their findings.
Case Involving California Candidate
In a separate filing, Kalshi said Kyle Langford, who ran for California governor last year, placed bets on his own candidacy. The company said those trades, which Langford promoted in a social media post, violated rules that prohibit political candidates from betting on their own elections. Kalshi said it fined Langford more than $2,000 and suspended him from the platform for five years. The company said that as a candidate in a race, a person can follow and use the market forecast but should not trade on it. Langford did not immediately respond to a request for comment.
Regulatory Context And Recent Incidents
Kalshi said it reported both cases to the US Commodity Futures Trading Commission. Insider trading is illegal in the stock market, while prediction markets operate under fewer regulations. In another recent incident cited within the industry, a gambler made nearly half a million dollars on the capture of Venezuela’s president shortly before it was officially announced, which raised questions about whether someone profited from inside knowledge of the US operation.
