MrBeast’s production company, Beast Industries, fired a video editor after prediction-market operator Kalshi accused the worker of insider trading, according to Associated Press. The company said the editor’s alleged trading activity violated its policies and that it would investigate independently. The case comes as prediction markets—online platforms that let users wager on outcomes—face ongoing debate over whether and how insider trading risk should be addressed.

In its account of the episode, Kalshi said last month that a user who traded about $4,000 on streaming markets related to MrBeast videos posted “near-perfect” results, according to AP. Kalshi later identified the trader as an employee of Beast Industries and said the worker “likely had access to material non-public information.” Kalshi suspended the editor from its platform for two years, fined him $20,000 and alerted federal regulators.

Beast Industries’ response, as described by AP, was immediate and punitive. A spokesperson for the roughly 500-person company said Beast Industries has “no tolerance for this behavior” and has initiated an independent investigation. Jeff Housenbold, Beast Industries’ president and CEO, told CNBC that he had taken action several months earlier to bar trading by MrBeast employees and contestants for Beast Games, MrBeast’s Amazon Prime reality-competition show.

Kalshi’s allegations also placed the incident in the broader policy debate surrounding prediction markets. The AP report said YouTube’s biggest channel, known for stunt-based challenges that have included large cash giveaways, is now at the center of questions about whether prediction markets function like gambling and how they are regulated. Kalshi is one of several platforms that allow wagers on the probable outcome of events, ranging from sports entertainment to geopolitical developments.

Federal regulation, AP reported, currently falls under the Commodity Futures Trading Commission rather than state gambling authorities. Critics have said prediction markets and regulators need to do more to prevent insider trading. Housenbold argued that prediction markets are especially vulnerable when people have access to information that is not public.

“The practice certainly looks like gambling,” Housenbold said in remarks to CNBC’s “Squawk Box,” according to AP. He also said the government must determine whether that is the case. Housenbold said that people can trade on private knowledge, adding, “You could be a third-party cameraman on set and know what the first song in the rehearsal is for a singer. You can be the person reviewing a script and knowing what the end result is,” before describing how “there’s so much information out there and it’s asymmetric and people are taking advantage of that.”
