Rick Ross and Nelly are expanding their respective empires into horse racing. They're now among a list of high-profile team owners of the National Thoroughbred League (NTL).

Ross and Nelly have long been avid sports fans, and their venture into the NTL is both on brand and unique. The NTL is being billed as a “first-of-its-kind” horse racing league – while horse racing has traditionally been a solo sport, the NTL has city-based teams. It'll also be one of the “first truly co-ed sports leagues.”

It'll debut over Labor Day weekend in Nashville and per a press release, the “weekend-long festival-like atmosphere” will be “akin to Formula I.” The debut will feature a concert and whiskey and bourbon lawn party in collaboration with Pappy Van Winkle.

Per Rolling Stone, "the six original teams will represent New York, Los Angeles, New Jersey, Seattle, Nashville, and Philadelphia. Each “Cup” will consist of a three-race series, run consecutively, and include horses from each of the six teams entered in every race. Accrued points will determine the overall winner, and the champion team at the end of the season will take home a $1 million grand prize."
