Best Illinois Sportsbook Promos & Bonuses 2025

Best Illinois Sportsbook Promo Codes

Our carefully selected Illinois sportsbooks have a diverse variety of promotions. Their sign-up bonuses are all about the initial impression of the platform, so they tend to be the best of the bunch. Below find the best Illinois sportsbook promo codes to access the latest deals and kickstart your sports betting journey in the Prairie State.

1. BetMGM Illinois Promo

Best for: In-person benefits

BetMGM truly knows how to treat its bettors well with a great welcome bonus, regular promotions, and a generous loyalty scheme. If you are searching for a sportsbook that excels at offering rewarding promotions, BetMGM stands out as a top choice.

You are eligible for a welcome offer of up to $1,500 in bonus bets by using our promo code WSNSPORTS when you sign up.

To get the offer, you have to make a qualifying minimum deposit of $10 and at least a $5 wager. What really impresses me is that you will receive the bonus if your initial wager loses. Meaning, I get to have a safety net on my first bet. The bonus itself is tied to your wagered stakes to a maximum of $1,500. So if you bet $100, you'll get $100 in bonus bets if your bet loses.

The bonus itself is split into five bonus bet stacks, which will expire after 7 days if you don’t use them. If you win with a bonus bet, you don’t get to keep your initial stakes, only the winnings you made on those bets.

BetMGM keeps the excitement alive with a range of ongoing offers, including parlay boosts, odds boosts, and special prizes. These offers are refreshed frequently according to particular events and seasons. It’s always worth checking the promotions page for the latest deals. Additionally, for each referral, you and a friend can grab $100 in bonus bets after they have played through $100 of their own money.

With every wager that you place, you'll earn BetMGM Rewards Points which, in turn, can be exchanged for betting bonuses or benefits at MGM resorts.

2. FanDuel Illinois Promo

Best for: Mobile app

FanDuel is at the forefront of the betting industry, leading the way in terms of total betting revenue. If you’re looking for a sportsbook that delivers frequent promotions and an unbeatable mobile experience, I have to recommend FanDuel.

Claiming the FanDuel Illinois promo gets you $150 in bonus bets, provided that you make a first bet of at least $5 and that bet wins. It is a worthwhile offer, as the minimal betting amount required is low.

You’ll get your bonus bets within 72 hours after your bet settles and is concluded to be a winning bet. Your bonus bets must be used within seven days.

FanDuel lets you use your bonus bets in whatever increments you want, which is great, but they can’t be combined with another promotion. For instance, if you placed a $20 bonus bet from your $150 welcome bonus, it would just be subtracted from your total to leave you with $130 in bonus bets. As usual, you only get to keep the winnings from a bonus bet.

Following this, you can invite friends with your unique referral link and earn an easy bonus. When your friend makes a bet of $10, you will both stand to gain $50 in bonus bets. Bettors are allowed to refer up to 5 friends every 30 days - that’s up to $250 in bonus bets a month. FanDuel also has several other bonuses, like odds boosts and same game parlays, that are frequently updated.

When you sign up for FanDuel, you are welcomed into the FanDuel Player Club. Your betting activity will accumulate FanDuel Points, unlocking certain rewards like premium customer support, FanDuel merchandise, special promotions, and even a personal account manager.

2. Register your account. Next, you’ll be asked to create an account. You’ll need to input details like your name, date of birth, email, SNN, and address. You might have to submit documentation to verify your identity as well.

3. Claim your welcome bonus. Now, you can claim your welcome offer, making sure that you know if you need to opt-in or use a promo code. Check out the table at the start of the page for the latest sports betting promo codes. Remember, you may need to use the code when you are typing in your details during the registration process.

What Type of Sports Betting Promotions Are There in Illinois?

Sports betting platforms in Illinois feature an array of promotions including welcome bonuses and ongoing offers. By creating a valuable and rewarding betting environment, these promotions are used to draw in new bettors and engage existing users. Let’s take a look at the types of bonuses that you’ll come across:

Terms and Conditions to Look Out For

Our key piece of advice is to always carefully read the terms and conditions before claiming any bonus. Sportsbooks often showcase the appealing parts of their offers at the forefront, leaving the finer details in the T&Cs.

When reading the T&Cs, here are the key aspects to look out for:

• Wagering Requirements: This term refers to the number of times that you have to bet your bonus amount before you can withdraw any winnings. For example, say you have a $20 bonus that is subject to 5x wagering requirements. You’ll have to place bets totaling $100 to withdraw any winnings from the bonus. This rule is used to make sure that bettors don’t just cash out their bonus straight away without placing any bets. Wagering requirements for online casino bonuses are typically much higher than those for sportsbooks, which are often as low as 1x.

• Minimum Deposit: Most bonuses will require you to deposit a little bit of money. For sportsbooks, minimum deposits tend to be $5 or $10, but can be higher to qualify for promotions.

• Qualifying Bet: Similarly, certain sportsbooks will require you to make a specific bet to unlock a bonus. It may need to be a certain size (like at least $20) or at certain odds (like -200 or greater). In some cases, your first bet has to lose to qualify for a bonus, like a second chance bet.

• Minimum Odds: Sometimes, bonuses stipulate that bonus bets have to be placed at specific minimum odds. This stops you from placing highly-probable bets to unlock their bonuses.

• Expiration Date: Every bonus has a date that you’ll need to claim and use it by. Otherwise, the offer will become invalid.

• Maximum Bet/Winnings: Often, there are restrictions on the maximum you can wager with bonus funds and how much you can win from promotions. The details of these limits can be read in the T&Cs.

Can I Claim Welcome Bonuses From More Than One Sportsbook in Illinois?

Absolutely! Bettors in Illinois are welcome to sign up with multiple online sportsbooks and benefit from each of their welcome bonuses. It is actually a smart move to maximize the benefits of these introductory bonuses, since they tend to be the most generous offers out there. Additionally, having multiple accounts helps you to compare the bonuses and odds, check out which platform is suited to you, and potentially increase your winnings.

With that being said, it is important to practice responsible gambling and not overdo it. For many people, it might be challenging to manage multiple accounts, and choosing to join only one sportsbook is a more sensible choice.

How We Rate the Best Illinois Sportsbook Promotions

At WSN, our team uses a hands-on methodology for evaluating promotions on sportsbooks. We go through the process of registering for the sportsbook, making a real money deposit, opting into the available promotions, and going over the T&Cs. This direct approach is rooted in our rating process, which allows us to assess the value and functionality of each bonus as accurately as possible. Our team has been a part of the industry for decades, so have a deep insight on what makes a promotion truly beneficial to bettors.

Here’s what we consider:

1. Accessibility - We look at how simple the process is to acquire the bonus. Do you have to opt-in or use a promo code? Is there certain criteria like minimum deposits or bets?

2. Value - We consider if the bonus is genuinely beneficial to you. Is it a fair offer and worth your time? How does it compare to the offers of competitors?

3. Type of Bonus - Are they free bets, deposit matches, second chance bets, or other kinds of bonus? What are the advantages of each kind and what sort of bettor are they suited for? Additionally, is it for a specific market or type of bet?

4. Playthrough - We assess the wagering requirements attached to the bonus, including how long we think it would take to clear a bonus. We’ll explore this in depth later on the page. 

5. Other terms and conditions - We ensure to delve into the fine print of the T&Cs, and see if there are any other requirements. This includes stuff like expiration dates, market restrictions, and any minimum/maximum limits. By evaluating this, we can highlight any important details that you should be aware of.
