Prediction Markets in Maine

Status: available. Last verified October 2, 2026.

Prediction markets such as Kalshi and Polymarket US are regulated federally by the Commodity Futures Trading Commission. We found no cease-and-desist letter, lawsuit or court ruling involving prediction markets in Maine as of October 2, 2026, and the Gambling Control Unit has not published a position on them.

Courts elsewhere are split. On September 25, 2026, the Sixth Circuit ruled for Ohio and Tennessee in KalshiEX LLC v. Schuler, and the Ninth Circuit ruled for Nevada, while the Third Circuit sided with Kalshi in New Jersey. The Supreme Court may settle the question. Sixth Circuit opinion

Prediction markets matter for matched betting because they do not limit winning traders. Check each app for current availability in Maine before you deposit.

Online Casinos in Maine

Online casinos are legal in Maine but not yet live. LD 1164 became law without the governor's signature on January 11, 2026. It gives the four Wabanaki tribes the only right to offer online casino games. Maine Legislature bill record

The Maine Gambling Control Unit is still writing the rules. Its third notice of rulemaking was published on September 30, 2026, with comments due by October 30, 2026. No online casino had launched as of October 2, 2026. Gambling Control Unit rulemaking page

In January 2026, Churchill Downs, which owns Oxford Casino, sued the Gambling Control Unit in federal court to challenge the tribal-only licenses. Legal Sports Report

Sweepstakes casinos are banned in Maine. LD 2007, signed on April 6, 2026, prohibits operating or promoting online sweepstakes games. Maine Legislature bill record

Maine Sports Betting Law and Timeline

  • May 2, 2022: Governor Janet Mills signed LD 585, which legalized sports betting in Maine and gave the state's tribes control of mobile sports betting. Maine Legislature bill record
  • November 3, 2023: Online sports betting launched with Caesars Sportsbook and DraftKings, regulated by the Maine Gambling Control Unit. Current licence holders are listed on the Unit's sports wagering page. Legal Sports Report
  • January 11, 2026: LD 1164, which legalized tribal online casinos, became law without the governor's signature. Maine Legislature bill record
  • April 6, 2026: Governor Mills signed LD 2007, which bans online sweepstakes games and makes operating or promoting them a Class D crime. Maine Legislature bill record, law text
  • July 29, 2026: The Gambling Control Unit warned that only licensed operators may offer online gambling in Maine and that unlicensed sites, often based outside Maine or overseas, have no oversight. Gambling Control Unit advisory

Offshore and unlicensed betting

Maine law requires a license for any sports wagering activity in the state, and the Gambling Control Unit can impose civil penalties of up to $25,000 per violation of the sports wagering chapter. 8 M.R.S. §1201, 8 M.R.S. §1205. The criminal code makes it a Class D crime to advance or profit from unlawful gambling, and a Class B crime to run a bookmaking operation that takes more than 5 bets totaling more than $500 in 24 hours. It is not a defense that the gambling takes place outside Maine. 17-A M.R.S. §954, 17-A M.R.S. §953, 17-A M.R.S. §957

These offences target operators. The code defines advancing and profiting from gambling so that a person acting only as a player is excluded, and no section makes placing a bet with an offshore site a crime for the bettor. 17-A M.R.S. §952. Since April 2026, operating or promoting an online sweepstakes game is also banned, with civil fines of $10,000 to $100,000. LD 2007 law text. The Gambling Control Unit has warned the public about unlicensed offshore sites but has not named any offshore sportsbook. July 29, 2026 advisory
