Beast Industries fired a MrBeast video editor this week following accusations of insider trading by prediction market operator Kalshi. Kalshi, an online platform that allows users to “trade on anything”, announced last month that a user who traded about US$4,000 on streaming markets related to MrBeast videos with “near perfect” success turned out to be an employee of Beast Industries who “likely had access to material non-public information”. Kalshi suspended the editor from its platform for two years, fined him US$20,000, and alerted federal regulators.
