Kalshi paid the editor of MrBeast for doing insider trading on markets related to the YouTube star

Editor of YouTube’s most popular creators, MrBeasthas been criticized by Kalshi’s market predictions insider trading on stage.

After investigation, Kalshi he said “found reasonable cause” to believe that this editor, Artem Kaptur, used public information about MrBeast’s videos to inform his betting on things related to MrBeast’s YouTube channel.

Prediction markets like Kalshi and Polymarket competition allow users to bet on various future events, such as who will win a political election, how many songs a certain singer will sell in a week, or the next season of a popular movie will be announced.

Kalshi did not disclose the amount of bets Kaptur placed on MrBeast, but some markets on the platform allow users to bet. the words that the creator will say on the upcoming video – confidential information that the video editor may touch. Kalshi users can also trade when MrBeast will get married, or his company, Beast Industries, announce an IPO.

A spokesperson for Beast Industries told TechCrunch that the company does not tolerate this behavior, and that it extends to the company’s employees, as well as contestants on MrBeast’s Amazon Prime show “Beast Games.” Competitors are also informed that their confidential information prevents them from participating in the prediction markets.

“In this regard, we have already launched an independent investigation as part of our overall efforts to ensure that our workplace is reliable and trustworthy with our global audience,” the spokesperson told TechCrunch. “We welcome Kalshi – and we hope others in the community – are also taking this issue seriously, but it only works if they are willing to share their findings, so we are hopeful that they will be open in the future.”

Kalshi claims that Kaptur sold about $4,000 in YouTube ad sales in August and September 2025. He made a profit of $5,397.58, which led Kalshi to pay him the amount, plus a penalty of $15,000. Kalshi also banned Kaptur for two years. The company said in a statement blog post that it will pay a fee to the consumer education organization.

Kalshi also pays the fine Kyle Langforda candidate for political office in California, who sold $200 in cash for his bid, then posted it on TV.

Markets on platforms like Kalshi and Polymarket are so large that it is difficult to ensure that users who are trading with them do not use private information for profit, which is against the law. When it comes to securities like stocks, similar behavior is punished until 20 years in federal prison.

The possibility of these markets being disrupted has raised concerns among US lawmakers.

Last month, another Polymarket user was suspicious bet $32,000 that Venezuelan President Nicolás Maduro will be removed from power at the end of January – a few hours later, the US military captured Maduro, and gave the operator $ 400,000.

In response, Representative Ritchie Torres (D-NY) proposed laws which would make it illegal for government employees to trade in the prediction markets regarding government policies, government actions, or political outcomes.

Kalshi CEO Tarek Mansour he said in a Linkedin post last month that he supported the bill, as Kalshi already followed the rules that would follow. He added that insider trading cases do not occur on US platforms (both Kalshi and Polymarket are based in the US).

“This American bill only applies to regulated, American companies and not to unregulated, non-American companies, which is where the alleged issues are,” Mansour said. “Prediction markets, like any industry, are not monotonous: there are important differences.”
