Maine iGaming Law Takes Effect July 29, Making the State the Eighth to Legalize Online Casinos
Maine's online casino law goes into effect on July 29, setting the stage for the state to become the eighth in the nation to allow real-money iGaming, with a launch expected as early as 2027.
Maine is moving forward with online casino legalization after Governor Janet Mills allowed a landmark iGaming bill to become law in January, and the legislation officially takes effect on July 29. The move positions Maine as the eighth state in the country to authorize real-money online casino gaming, joining Connecticut, Delaware, Michigan, New Jersey, Pennsylvania, Rhode Island, and West Virginia. An actual launch, however, is still months away as regulators prepare rules and begin licensing operators.
The law, known as LD 1164, grants each of Maine’s four federally recognized Wabanaki Nations tribes the exclusive right to partner with one commercial online casino operator. That structure gives up to four platforms a path into the state, with DraftKings and Caesars — who already operate licensed mobile sportsbooks in Maine — considered strong candidates given their existing tribal partnerships. BetMGM, FanDuel, and Golden Nugget Casino are also among the platforms likely to pursue licenses.
A Tribal-Led Effort Years in the Making
The road to iGaming legalization in Maine was shaped almost entirely by the political and economic circumstances of the Wabanaki Nations — the Penobscot Nation, Passamaquoddy Tribe, Mi’kmaq Nation, and Houlton Band of Maliseet Indians. Combined, the four tribes have approximately 10,000 members, and their advocates have argued for years that federal and state policy failures denied them the same economic rights enjoyed by tribal nations elsewhere in the country.
The tribes pushed for online casino legislation after finding early success with a 2022 sports betting bill that gave them exclusive control of mobile wagering in the state. The sports betting law passed and was signed by Mills, with DraftKings and Caesars Sportsbook launching in November of that year. Online casino gaming follows a similar model, with each tribe partnering with a third-party operator and sharing revenue under the law’s terms.
The iGaming bill’s path was not without obstacles. Mills initially opposed the legislation, a significant hurdle given her previous positions on gambling expansion. Her decision to allow it to become law without her signature in January shocked much of the state’s political establishment and cleared the way for a regulatory process that was previously considered uncertain.
What Operators and Players Can Expect
The law sets an 18% tax rate on online casino revenue, a figure officials project could generate around $100 million annually once the market matures. The Maine Gambling Control Unit will oversee the industry and is expected to begin the formal rule-making process once the law takes effect on July 29. Milt Champion, the unit’s executive director, has said the rule-making process could be relatively quick, setting up potential operator launches as early as the beginning of 2027.
The law does not permit online casinos to go live before the rule-making process is complete and licenses are issued. That means Maine players will continue to wait for a regulated iGaming option even after July 29, though the framework will now be in place and the regulatory clock officially running.
DraftKings occupies a particularly advantageous position given its existing partnership with the Passamaquoddy Tribe for sports betting operations. Its familiarity with Maine’s regulatory environment and established player base in the state give it a natural head start. The DraftKings Promo Code is already available to Maine sports bettors, and a casino expansion would extend that footprint considerably. Caesars, which operates the second sportsbook in the state, is similarly positioned through its tribal agreement.
Maine’s move is being watched closely by states like Massachusetts, where iGaming legalization has repeatedly stalled. Advocates expect Maine’s launch to provide a useful case study for neighboring states still debating whether to permit online casino gaming. The Caesars Sportsbook Promo Code remains available for Maine sports bettors in the meantime, with the casino component of Caesars’ offering set to follow the state’s regulatory timeline. Players interested in sweepstakes gaming before legal iGaming arrives can access options like the HelloMillions Promo Code as a social casino alternative available in all 50 states.
With the law now set to take effect and a clear regulatory structure in place, Maine’s iGaming market is moving from possibility to inevitability — though the patience of would-be players will be tested before the first online casino goes live in the Pine Tree State.
