The legal position in Maine
Maine legalised online sports betting in 2023 with a model that reserves online licences for the state’s federally recognised tribes — one of the few states to do it that way. On prediction markets, Maine has been quiet: we are not aware of any state enforcement action against the CFTC-regulated platforms as of mid-2026, and they advertise availability.
The federal basis for all of this is the same everywhere: CFTC-designated exchanges treat event contracts as derivatives, not bets — see our US legality overview for how that argument works and where it is being tested.
Which platforms operate in Maine
Kalshi, its brokerage-routed products and Polymarket generally serve Maine. The tribal-run sportsbook market is small, so for many categories — politics, economics, weather — the exchanges are the only game in town anyway.
We are not aware of a specific state block as of June 2026, but this landscape changes quickly and this page is general information, not legal advice. The platform’s own eligibility check at sign-up is always the authoritative source for your address.
Sources: public reporting on the 2026 federal-versus-state prediction-market litigation. Availability and legal status change frequently; verify the current position with the platform and, for legal questions, a qualified professional. Nothing here is legal advice.

Frequently asked questions
Are prediction markets legal in Maine?
They operate under federal CFTC regulation and we are not aware of a Maine state action against them as of mid-2026. Maine's own online betting is tribal-run and sports-only, so the exchanges cover far more ground.
What makes Maine's betting market unusual?
Online sports-betting licences are reserved for Maine's tribes — a model few states use. Prediction markets sit outside that system entirely, under federal derivatives regulation.
