Will Sports Wagers Be A $361M Cash Cow In Colorado? Gambling Rivals Don’t Agree On It Ben Markus, Colorado Public Radio · February 14, 2019 at 6:48 pm Colorado sports gambling could ring up $361 million in revenue by 2023, according to a market analysis paid for by the owners of the state’s lone horse track in Aurora. Casinos, long an opponent of the track, were quick to question the number — but wouldn’t share their own analysis. This is first public estimate of the potential size of sports betting in Colorado. The analysis assumes a widespread industry, with bets allowed online and on mobile devices, as well as at physical locations like casinos, the horse race track, and off-track betting locations around the Front Range.
