Prediction market platform Kalshi suspended the account of Artem Kaptur for two years. An investigation confirmed the employee utilized non-public data, placing winning bets on events surrounding the MrBeast YouTube channel.
During August through September 2025, Kaptur executed trades worth $4,000 within the YouTube streaming section. The trader generated a total net profit of $5,397, which the platform immediately confiscated in full.
Kalshi hit the user with an additional $15,000 fine. The platform's management will direct the recovered funds toward a specialized consumer protection non-profit.
