Following the overturn of PASPA, the act that kept sports betting illegal in the US for decades, the Great Lakes State was quick to jump on board, legalizing online sports betting in 2021. Since its early launch, Michigan bettors have enjoyed access to some of the top sportsbooks available in the country.
On this page, we'll take a closer look at the best sportsbook promo codes currently available in September 2025, and how to make the most of them. Whether you're just beginning your sports betting career or you're simply looking for a new book to add to your lineup, we've got all the info you need.
The Role of Promo Codes in Michigan Sports Betting
Home to some of the biggest names in the online sports betting industry, Michiganders are spoiled for choice. Carefully competing for customers, each sportsbook offers welcome bonuses to new customers, some of which are locked behind promo codes.
Promo codes are a great way to start off betting with a new operator with some extra firepower. The biggest names in the game do not offer promo code deals for first-time sign-ups. This means that when you register and claim a welcome bonus with FanDuel or DraftKings in Michigan, you can rest assured that you're getting the best possible deal currently. Our recommendation is to create accounts with multiple operators in order to ensure that you'll be able to access the top odds for your bets AND be able to claim multiple welcome bonuses!
Getting the Most from Michigan Sportsbooks Without a Promo Code
As mentioned above, the most popular sportsbooks in Michigan don't require a promo code in order to access their welcome bonus when signing up. Oftentimes, the best offer available is already built into the sign-up process.
Although no promo code is required/available for these bonuses, you're still getting a great deal, usually in the amount of a few hundred dollars in bonus bets simply for creating an account and making a qualifying deposit.
Our tip for getting the most out of your new sportsbook account is to always read the terms and conditions after downloading your Michigan sportsbook app, before getting started betting or making a deposit. You wouldn't want to miss out on those bonus bets!
Is There a No-Deposit Promo in Michigan?
Currently, in September 2025, you won't find any no-deposit bonuses available for use at any of the legal sportsbooks in Michigan. No-deposit bonuses are exactly as they sound, a bonus that can be claimed by simply creating a new account with a sportsbook, no need to make a first deposit.
While no-deposit bonuses are largely a myth, Michigan welcome bonuses make up for it with generous bonus offers that are relatively easy to claim. Most require a deposit of at least $5-$10 and that your first bet is either a winner or a loser. These conditions, of course, change from book to book, so you'll definitely want to fully read through the terms and conditions of any offer you're after!
