Wyoming legalized mobile sports betting in April 2021 under HB 133 (opens in a new tab), making it one of the early adopters in the Mountain West. The Wyoming Gaming Commission regulates a small but established licensed market — DraftKings, FanDuel, Caesars and BetMGM all hold WY mobile licenses, generating roughly $200M in annual handle. The state's licensed sportsbook market is small relative to its population because Wyoming itself is small (population ~580K). The Wyoming AG and Gaming Commission have not moved against CFTC-regulated prediction markets, and Wyoming's broader regulatory tradition favors light-touch federal-deference approaches.

For Wyoming residents, this means nearly every major CFTC-regulated platform is available statewide, including Kalshi, Polymarket US, Robinhood, OG.com, Fanatics Markets, Sleeper, Novig, Chalkboard and Rebet. Only DraftKings Predictions and FanDuel Predicts are voluntarily geofenced (because their parent companies hold WY mobile sportsbook licenses to protect).

Why Wyoming Is Quietly Permissive

Three reasons:

  1. Federalist legal tradition. Wyoming has historically deferred to federal regulators on novel interstate-commerce questions. CFTC oversight of event contracts is treated as definitive.
  2. Small licensed market = low political pressure. With only ~$200M annual sportsbook handle, the revenue at risk from CFTC competition is modest. There is no organized industry lobbying the AG to act.
  3. No tribal gaming dynamic affecting prediction markets. Wyoming has the Wind River Reservation (opens in a new tab) with the Eastern Shoshone and Northern Arapaho, but neither tribe has joined any prediction-market litigation.

What Wyoming Residents Can Trade Right Now

Wyoming-specific market depth is strongest on Denver Broncos (the closest major NFL franchise), Wyoming Cowboys (NCAA) and federal Senate / gubernatorial markets.

  • Government ID + SSN for KYC verification.
  • US bank account or debit card.

Tax Treatment for WY Residents

What could change the status

Dates we are watching: Nevada's responses to the Robinhood and Crypto.com Supreme Court petitions are now due November 13 and 16, 2026 (both extended in October), and Kalshi's response to New Jersey's petition is due November 9, 2026 (deadlines can be extended); the earliest the Supreme Court could act on the petitions is a conference in December 2026 or January 2027 (our estimate, not a scheduled date). We re-check this page when any of these happen and log the change above.
