Kalshi Fines Former Gubernatorial Candidate, MrBeast Employee on Prediction Wagers
The prediction-market platform is cracking down on potential instances where users may have traded on inside information or manipulated markets

A former California gubernatorial candidate and a video editor to YouTube streamer MrBeast were fined by Kalshi for violating its rules for making prediction-market wagers on its platform.

Their fines were the first disciplinary actions to be disclosed publicly by Kalshi, the company said.

Kyle Langford, who ran for governor in California, was fined $2,246.36, including the amount related to his trades and penalties of $2,000, and banned on the platform for five years after posting a video on X seemingly showing him betting on his victory, according to a notice posted on Kalshi’s website.

Kalshi prohibits candidates of political race from making bets in markets related to their own elections, as well as those employed by political-action committees.

“As a candidate, Langford qualified as a direct decision maker for this contract and had direct influence on the outcome of the underlying event,” Kalshi said in the notice.

Kalshi also invoked disciplinary action against Artem Kaptur, who traded around $4,000 on markets tied to MrBeast’s videos while working for the YouTube star. Kalshi said it fined the user $20,397.58, including his profits and penalties of $15,000, and enacted a 2-year account suspension.

Kalshi was notified of the trades by its surveillance systems and users who noticed Kaptur’s “near-perfect trading success on markets with low odds, which were statistically anomalous”

“In both cases, our team collected evidence, applied Kalshi’s disciplinary process fairly, and concluded there was sufficient evidence that a trading violation occurred,” Bobby DeNault, head of enforcement, wrote in a post on Kalshi’s website.

A representative for MrBeast didn’t immediately respond to a request for comment.

“Tensions between the U.S.A. and Iran are at an all-time high and the media has chosen to cover a $200 campaign gimmick (aka betting on I, myself) from last year,” Langford said in a statement. “Is this really the state of our political discourse?”

The proliferation of prediction markets has raised concerns about users making trades using inside information and manipulating markets to score windfalls.

The prediction market platform said it reported both cases to the Commodity Futures Trading Commission. The fines were imposed by Kalshi, depending on the size of the trades and which rules they violated, which said it would donate them to a nonprofit organization. Neither trader withdrew their profits from their accounts.

Kalshi and Polymarket, a rival prediction-markets platform, let users bet on everything from election victories to the outcome of sporting events to how many inches of snow New York City will receive this week.

As prediction markets explode in popularity, Kalshi said that it has opened 200 investigations over the past year on potential cases of insider trading on its platform and that more than a dozen so far have been found to be possibly in violation of Kalshi’s rules.

“No financial exchange is immune from bad actors,” wrote DeNault. “We’re committed to deterring and finding the bad actors, manipulators, and those who willingly cheat.”
