The story of legal sports betting in Colorado

The journey to legal sports betting in CO started back in 2019, when Proposition DD was passed. This measure meant that sports betting became legal and taxable in the state, and the race was on to set up the necessary regulation.

Unlike some other legal betting states, Colorado chose to take a careful approach, with legal online sports betting only officially launching on May 1st, 2020. While that meant a longer wait for ardent sports fans, it also allowed the state to put some of the best legal frameworks in place, which makes the Centennial State’s legal betting sites some of the safest in the country.

DraftKings, BetRivers, FanDuel, and BETMGM were the first of Colorado’s legal sports betting sites to launch, going live the very first day sports betting was legalised on the 1st of May, 2020. 

Since then, other massive players like BetWay and PointsBet have joined the growing list of reputable Colorado legal sports betting sites, with even more set to follow.

Tops tips for playing safely on Colorado legal sports betting sites

  1. Be aware of phishing sites. Legal sports betting is a multimillion-dollar industry – and that makes it very attractive to scammers. Fake sites can look extremely convincing. To make sure you land on a legit site, either bookmark their homepage, or follow a link from a trusted partner like Betting America.  
  2. If it sounds too good to be true… it probably isn’t. Always read the fine print and make sure you understand the rules before parting with your money. 
  3. Make sure your browser and antivirus software are up to date. You can pick up viruses, malware, and keyloggers all over the internet, which put you at risk of having your credit card details stolen. 
  4. Check new sites for reviews, certification with the relevant gambling authority, and player safety protocols. (Alternatively, stick with the sites which we list here and have verified for you!) 
  5. Only ever wager what you can afford to lose. There are no guarantees, and even the very best sports players and teams have bad days. Don’t put yourself in financial hardship over something which is meant to be fun. Remember that judgment-free help is available
