Prediction Markets
in Idaho
Idaho has a restricted status because Manifold Markets has proactively blocked real-money Sweepcash features for Idaho residents under its terms of service. Kalshi, Polymarket QCEX, PredictIt, and Robinhood all remain available: Idaho residents can still trade on the four most important platforms. Idaho has no legal sports betting and a 5.8% top income tax rate. The Manifold restriction reflects Idaho's conservative gambling laws, not a state enforcement action.
Which platforms work in Idaho?
Kalshi available in Idaho. CFTC federal jurisdiction, no state enforcement action.
Polymarket QCEX available in Idaho. No enforcement action taken.
Manifold Markets restricts real-money Sweepcash features in Idaho per its terms of service. Play-money Mana is still available.

Robinhood prediction market contracts available in Idaho.
The Manifold restriction explained: Manifold proactively restricted its Sweepcash (real-money prize) feature in Idaho, Delaware, Michigan, and Washington based on its own legal assessment of gambling laws in those states. This is a platform-level decision, not a state enforcement action: Manifold was never ordered to restrict Idaho residents.
