Prediction Markets
in Maine
Maine is fully open for prediction markets: all major platforms available, no enforcement actions, and mobile sports betting launched in November 2023. Maine's 7.15% top income tax rate is moderate for New England: lower than Vermont (8.75%) and Massachusetts (5% flat, but Polymarket blocked there). With all platforms accessible, Maine is one of the cleaner options in northern New England for prediction market trading.
