MrBeast Video Editor Fired From Beast Industries Following Kalshi Insider Trading Probe

Beast Industries, the firm behind YouTube star MrBeast’s growing media and consumer goods empire, has fired a video editor for insider trading following an internal investigation.

Employees were recently informed about the former video editor’s termination via an email, which further underscored the company’s strict stance against abusive behavior on prediction markets among staff, a source familiar with the matter told Decrypt.

The individual, Artem Kaptur, was suspended last week after Kalshi unveiled an enforcement action against him. The prediction market platform determined that he likely used knowledge about the content of MrBeast’s videos with “near-perfect trading success on markets with low odds,” which was flagged by Kalshi’s surveillance systems.

When Kalshi said that it had fined Kaptur $20,000 for $4,000 worth of improper wagers, it was among the firm’s first disclosures regarding efforts to police activity in a space that’s drawn increased scrutiny from U.S. lawmakers amid suspicious trading activity in recent months. That includes topics on Polymarket like Venezuelan President Nicolás Maduro’s ouster in January.

Although lawmakers’ concerns have largely focused on the potential abuse of classified military intelligence and ethical issues associated with topics like war and death, Kaptur’s termination shows how quickly companies can react when it comes to addressing bad actors. 

After Kalshi unveiled the enforcement action against Kaptur, a Beast Industries spokesperson told Decrypt that the company’s restrictions regarding insider trading on prediction markets extend to contestants participating in the firm’s reality competition series, Beast Games.

“We have a longstanding policy in place against employees using proprietary company information which safeguards the highest standards and ethics throughout our organization,” they said. “Beast Industries has no tolerance for this behavior.”

MrBeast, also known as James Stephen Donaldson, has more than 500 million followers across social media. Before acquiring a banking app for teens called Step in February, his firm received a $200 million investment in January from leading Ethereum treasury firm, BitMine Immersion Technologies.

Klashi continues to facilitate wagers on MrBeast’s videos, which tend to focus on what he’ll say next. The same goes for Polymarket, which hosted three markets associated with the YouTube creator on Wednesday that had generated at least $100,000 in trading volume each.
