Best Maine Sportsbook Promos (2026)

List of Maine Sportsbook Promo Codes – September 2026

Maine officially legalized sports betting on July 31, 2022, when Governor Janet Mills signed LD 585 into law. This piece of legislation allowed each of Maine's four Native American tribes to launch online and retail sportsbooks in the Pine Tree State.

The Maliseet, Micmac, and Penobscot tribes partnered with Caesars Sportsbook; meanwhile, the Passamaquoddy Tribe chose to team up with DraftKings Sportsbook.

This created what many are calling a "DraftKings and Caesars duopoly" on Maine sports betting, and these two popular U.S. sportsbooks went live in the state on November 3, 2023.

Take a look at the table below to find a full list of Maine sportsbook promo codes and sign-up bonuses in July 2026:

Types of Maine Sportsbook Welcome Offers & Promotions

So, what are the different kinds of welcome offers and sign-up bonuses provided by Maine betting apps? Here are some of the most common types you'll come across:

Second Chance Bets

Second-chance bets, also commonly known as a first-bet reset, offer a safety net for your initial wager. If your first bet loses, you'll receive a refund in the form of bonus bets or site credit, usually up to a certain amount. This allows you to start betting with a bit of extra security.

Bet & Get Promotions

"Bet & Get" promotions reward you with bonus bets or bet credits when you place a qualifying wager. For example, you might receive $200 in bonus bets after placing any wager of $5 or more. It's a straightforward way to boost your account balance at some of Maine's most popular sportsbooks.

No Deposit Bonuses

No deposit bonuses give you a small amount of bonus funds simply for signing up, without requiring an initial deposit. This allows you to explore the sportsbook and place bets without any financial commitment.

Unfortunately, no-deposit bonuses are rarely offered by sports betting apps in Maine or other U.S. states. These promotions are much more common in online casinos and (in our experience) are much less frequent among sports gambling sites.

Special Offers for Maine Sports Teams

Lastly, some ME sportsbooks will provide special offers (e.g., odds boosts) for betting markets involving sports teams that are popular among Maine residents.

Even though Maine doesn’t have major professional sports teams and betting on in-state colleges like the University of Maine Black Bears isn’t allowed due to state regulations, sportsbooks often feature promotions for nearby teams.

For example, you might find enhanced odds on games involving Boston teams like the Red Sox, Celtics, or Bruins. These regional favorites can be a big draw, so keep an eye out for these special offers to get extra value on your bets and enjoy the action even more.

Tips for Claiming & Using Maine Sports Betting Bonuses

Before we wrap things up, here are some tips to help you make the most of your Maine sportsbook promo codes and sign-up bonuses:

• Read the Terms and Conditions: Always check the fine print for each promotion. Understanding the terms, such as minimum deposit amounts, wagering requirements, and eligible markets, ensures you know exactly what’s needed to qualify for and make the most of your bonus.
• Check for Promo Codes: Some bonuses require specific promo codes to be entered during registration or deposit. Make sure to use the correct code to activate the offer and avoid missing out on any potential rewards.
• Understand Wagering Requirements: Many Maine sportsbook promos come with wagering requirements that dictate how many times you need to bet the bonus amount before you can withdraw any winnings. Familiarize yourself with these requirements to avoid any surprises.
• Monitor Expiration Dates: Bonuses often come with expiration dates or time limits. Keep track of these deadlines to ensure you use your bonus funds or bonus bets before they expire.
• Be Selective with Your Bets: Use your bonus funds wisely by placing bets on markets where you have the most knowledge or confidence. This strategy can help you meet wagering requirements more effectively and maximize your potential winnings.
• Stay Within Your Budget: Even though bonuses can provide extra value, always bet responsibly and stick to your budget. Bonuses are meant to enhance your betting experience, not lead to overspending.

By following these tips, you can take full advantage of the sports betting bonuses available in Maine and put yourself in a position for long-term success!
