Major Operator

BetMGM Sportsbook in South Dakota


BetMGM is the dominant retail sportsbook operator in South Dakota, partnering with two of the five Deadwood commercial casinos. Its on-property mobile app is the only mobile betting option in the state today — but it is geo-fenced and stops working the moment you step off Tin Lizzie or Cadillac Jack's property.

Mobile App in South Dakota

BetMGM offers a full-featured mobile app, but in South Dakota it is restricted by geofencing to only function while you are physically inside one of its two partner casinos. Statewide mobile betting is not legal in SD.

Notes

BetMGM's footprint reflects MGM Resorts' nationwide push to land retail partnerships in restricted-market states. Whether SJR 504 passes in November 2026 will determine if BetMGM can offer true statewide mobile betting in SD.
