Reno-based Monarch Casinos & Resorts agreed to pay a $400,000 fine to Colorado gaming regulators after executives from the company’s Black Hawk casino discovered and self-reported that three of its sportsbook employees were placing proxy bets on behalf of customers.

Proxy wagering, in which a person other than the account holder places a sports bet for a customer, is illegal in Colorado and most other states. Proxy wagering is legal in Nevada as long as the sports betting account holder registers with an approved proxy service.

According to a stipulated settlement filed with the Colorado Limited Gaming Control Commission, Monarch representatives agreed with the findings of an investigation that found 79 proxy wagers totaling almost $61,000 were placed for 11 different customers from January 2021 to June 2022.
