Horse-racing fans will be able to bet on May 1’s Kentucky Derby, thanks to a unanimous vote of the Nevada Gaming Commission Thursday.

Following an hourlong hearing, commissioners agreed to amend an existing regulation to allow the state’s more than 120 sports-betting locations to use a nationally televised broadcast to determine the results of the race instead of licensed disseminators.

Las Vegas Dissemination Inc. and Nevada Disseminator Services Inc. have been unable to negotiate a contract with Churchill Downs, the Louisville, Kentucky-based horse-racing track that conducts the Kentucky Derby, horse-racing’s most famous event and the first leg of the Triple Crown of horse racing, to provide race results.
