Sports betting is not legal in Wyoming and that ruling is unlikely to change in the near future. Multiple bills were proposed in early 2020, but those were shot down by the House and that could mean Wyoming's first chance of legalized sports wagering may have to wait until 2022, at the earliest.
The support for sports betting and gambling in general isn't overwhelming and that's mainly why there are just three casinos and two racetracks throughout Wyoming.
Daily Fantasy Sports have not been addressed in legislation, so they are permitted, and that should remain the case as there have been no efforts to overturn them. Horse racing betting is also legal.
