Maine Online Sportsbooks

Maine sports betting law allows each of the state’s four federally recognized Indian tribes to apply for online sports betting licenses in partnership with one third-party provider apiece.

In theory, that means there’s room for up to four Maine betting sites. However, Caesars Sportsbook has partnered with three of the state’s four tribal casino operators, while DraftKings has partnered with the other to offer online sports betting in Maine.

Sportsbooks currently available in Maine:

• Caesars Sportsbook
• DraftKings Sportsbook

Maine Sports Betting Bonuses

Maine’s licensed betting sites collectively boast a healthy variety of welcome bonuses for new users and ongoing promos for existing customers.

In addition to welcome bonuses, Maine sports betting apps launch new promotions regularly. Some of the types of Maine sports betting bonuses bettors can expect include:

• Odds boosts: Enhanced payouts when your selected team wins
• Early payouts: Place a bet and get paid immediately if your team gets ahead by a certain number of points, regardless of what happens later
• Parlay insurance: Get a refund if your parlay loses by just one leg
• Random bonus bets: Maine’s sportsbooks also randomly issue bonus bets to existing customers, often to entice them to return after some time of inactivity
• Loyalty programs: Sportsbook loyalty programs can add significant value to customers’ bottom lines by issuing cash, discounted hotel stays, trips to live sporting events, and more

Maine Sports Betting Promotion Regulations

BettingUSA always advises bettors to read every offer’s terms and conditions before claiming it, but regulations adopted by the Maine Gambling Control Unit ensure sportsbooks offer fair, easy-to-understand promotions.

For example, Chapter 64 of Maine’s sports betting regulations requires all betting promotions to meet the following standards:

• Terms and conditions that are accurate, clear, and not misleading
• Prominently display the terms and conditions anywhere the offer is advertised
• Disclose whether bettors must risk their own money when participating in any promotion
• Do not advertise promos as “risk-free bets” if the customer must wager their own money
• Do not restrict customers from withdrawing deposited funds as a condition of participating in any promotion

Maine Sports Betting Locations

The Maine Gambling Control Unit may issue up to ten retail sportsbook licenses to casinos, race tracks, and off-track betting facilities (OTBs).

The current list of Maine sportsbooks includes:

• Caesars Sportsbook at Oddfellahs in Portland
• More to come…

Other locations that may apply for sportsbook licenses include Maine’s two casinos:

• Hollywood Casino Bangor

And four other OTBs:

• Favorites OTB in Waterville
• Favorites OTB in Sanford
• Winners Circle OTB in Lewiston
• Winners OTB in Brunswick

BettingUSA will update this page as additional Maine sportsbooks open.

Maine Daily Fantasy Sports

Maine did not pass DFS regulation until 2017, but that did not stop the major DFS sites from operating throughout the state. In 2017, lawmakers passed a regulatory bill instituting a licensing requirement and consumer protection regulations.

Now, Maine fantasy sports sites must apply for licenses from the Gambling Control Unit and undergo annual audits to ensure compliance with all consumer protection regulations. Fans can read more about DFS in Maine below:

Maine Online Gambling

Legal online casinos are coming soon to Maine. In January 2026, Governor Mills announced her decision to allow LD 1164 become law without her signature. However, it remains uncertain when the first Maine online casinos will launch, as the state must now draft additional regulations, review licensing requests, conduct integrity testing, and issue launch approvals.

In a press release, Janet Mills described the bill as an opportunity to support economic development in tribal communities. To that end, the law grants the exclusive right to operate online casinos to Maine’s four federally recognized tribes: the Penobscot Nation, the Passamaquoddy Tribe, the Houlton Band of Maliseet Indians, and the Mi’kmaq Nation.

It’s uncertain what the Maine online gambling landscape will look like once it’s up and running, but Caesars Entertainment has an existing relationship with three of the state’s tribal casinos, and DraftKings has a relationship with the other. In all likelihood, that means residents will have access to at least two established online casino brands:

• Caesars Palace Online Casino
• DraftKings Casino

It remains to be seen if other online casino operators will secure access to the Maine online gambling market. BetMGM, FanDuel, and Fanatics Betting & Gaming opposed the bill, indicating they’re pessimistic about their odds.

Key points from the law include:

• Minimum age to play: Players must be 21+ to gamble online in Maine.
• One online casino per tribe: Each tribe is eligible for one license and may partner with a single commercial operator (similar to the existing mobile sports betting framework).
• Tax rate: Net revenue from online gaming is taxed at 18%. This is higher than the state’s 10% tax on mobile sports wagering.
• Oversight: The Maine Gambling Control Unit (MGCU) will regulate all online casinos in Maine.
• Responsible gambling: Licensed Maine online casinos must provide voluntary responsible gambling controls (e.g., custom deposit/wagering limits), offer self-exclusion to players who request it, and adhere to strict marketing standards

Tax revenue from online gambling is earmarked for specific public services, including:

• Gambling addiction prevention and treatment
• Substance use disorder supports
• Emergency housing relief
• Support for Maine’s veterans’ homes

Maine Online Poker

Maine included online poker in its 2026 gambling bill, but players should not expect the state’s first real-money poker sites to launch anytime soon.

One major hurdle is liquidity. The Maine online gambling bill did not include authorization for interstate player-sharing, meaning Maine will remain a ring-fenced poker market until lawmakers pass additional legislation that would allow the state to join the Multi-State Internet Gaming Agreement.

As a result, Maine, with a population of around 1.4 million, will remain an economically unviable market for operators like WSOP Online. DraftKings could potentially offer Electric Poker (3-handed hyper-turbo tournaments with random prize pool multipliers) in Maine, but full-fledged online poker remains unlikely in the near term.

Maine Online Lottery

The Maine Lottery does not sell tickets online, but players may use third-party courier services like Jackpocket and Lotto.com as a workaround. These courier services, which hold licenses in other states (Maine does not regulate lottery couriers), purchase official tickets on behalf of customers and notify them of wins.

Maine Gambling Laws

The Maine Gambling Control Board was established in 2004 and serves as a regulatory body over the state’s two land-based casinos.

Maine’s gaming laws inflict significant penalties on those who organize or “advance” gambling but appear to have no measures in place to punish those who merely participate as players. The state defines gambling with the following text:

“A person engages in gambling if he stakes or risks something of value upon the outcome of a contest of chance or a future contingent event not under his control or influence, upon an agreement or understanding that he or someone else will receive something of value in the event of a certain outcome.”

The state considers it a Class D crime if a person profits from an unlawful gambling activity or plays a slot machine under the age of 21. Note that “profiting” does not mean acting as a player; it means earning money by hosting an unauthorized gaming operation.

The punishment for a Class D crime is up to 364 days in jail and up to $2,000 in fines.

Additionally, one can be charged with a Class B crime if hosting an unlawful gaming activity that accepts more than 5 bets totaling more than $500 in a 24 hour period or receives more than $1,000 in a 24-hour period for hosting an unlicensed lottery, mutuel or other gambling scheme.

The punishment for this one is much stiffer at up to 10 years imprisonment and up to $20,000 in fines.

Some interpretations of existing law may expose individual gamblers to prosecution for merely participating as players, but the state has never charged someone for placing wagers online.

Still, it would be best to avoid doing business with illegal online betting sites.
