Best Sportsbook Referral Bonuses in May 2025

Gambling Problem? Call 1-800-GAMBLER

The name is self-explanatory. A sportsbook referral bonus is a promotion rewarded for inviting friends to a betting site. With each program I've used at an online betting site, I've received a unique referral code or link to send to my friends. My referrals then had to register for an account using the link or code and meet some conditions. 

To qualify for these sportsbook promos, you may need to fulfill certain requirements such as making an initial deposit and placing a bet. Once these conditions are met, the operator grants a bonus to your account, usually ranging from $20 to $100.

Every sportsbook's refer-a-friend bonus includes usage rules, such as the type of bets you have to place to qualify for the bonus. Some even have a wagering requirement you have to meet before withdrawing any winnings. 

I've spent plenty of time wagering with these sports betting apps and using the various promos to give you a conclusive answer on who boasts the best sportsbook referral bonuses. If you know people looking to get into sports betting, you can quickly boost your bankroll.

I've found the process of inviting friends to online sportsbooks to be straightforward. Here's how you can start referring interested parties and claiming the best sportsbook referral bonuses:

1. Open your chosen sportsbook's promotions tab or bonus page and opt-in to the referral program
2. Copy the unique referral link (some sites offer referral codes as well as referral links)
3. Send the referral link or code to your friend(s) via email or text
4. Have your friend sign up for an account using the link
5. Ensure your friend meets the requirements attached to the bonus

You will receive a notification once the invitee signs up using your link or referral code. Each referral bonus I've claimed from the best sportsbooks has arrived without any issue. Let's dive into the best ones.

The best sportsbook referral bonus arguably comes from FanDuel — $75 in bonus bets. You'll receive your reward once your friend settles a $5+ bet.

What is the FanDuel referral bonus value?

The FanDuel sportsbook referral bonus is worth $75 per person. Each friend you refer will score you that amount, assuming they follow the necessary steps after signing up.

Giving the sportsbook an edge in the FanDuel vs DraftKings debate, you can refer up to five friends every 30 days — as opposed to DraftKings' limit of five total. You can receive $375 every month if you refer the maximum number of people each period.

How to claim the FanDuel referral bonus

To claim the FanDuel referral bonus, follow the steps below:

1. Open the FanDuel promotions page.
2. Head to the refer-a-friend section.
3. Click the 'Invite friends' tab to generate the referral link.
4. Share the link with a friend and ask them to sign up for an account.
5. Wait for your referee to fund their account with at least $5 and place a $5+ wager.
6. Once the bet settles (must be within 30 days of registration), you and your friend will each receive $75 in bonus bets.
7. You can refer up to five friends per 30 days.
8. The bonus funds expire after seven days.

You can garner a $100 referral bonus from BetMGM when you get a friend to join the historic sportsbook. Do this 20 times in one month — the maximum number of referrals you're allowed to make — and you'll have an impressive $2,000 in bonus funds bolstering your bankroll.

What is the BetMGM referral bonus value?

The BetMGM referral bonus doles out $100 to you and each of your invited friends, but there are some stipulations attached. Namely, your friend must use your referral link within 30 days and wager through the bonus amount once at odds of -200 or longer. 

When you receive the $100 bonus, you must also meet a 1x playthrough requirement at odds of -200 or greater to unlock it. 

It's worth noting that if your referee opts to claim the $100 bonus, it will count as their sportsbook welcome offer. That means they won't be eligible for another new-user bonus.

Keep in mind that both you and your referral must also be from the same eligible state. For example, if you send them a link from the BetMGM Ohio app, they'll need to join through that same app to qualify for the promotion.

Referral programs are widespread across various industries, and it's crucial to consider several factors when evaluating these promotions.

Personally, I always start by confirming the bonus size. While some sites offer $100 per referral, others may only provide $20. Additionally, it's important to note that while most refer-a-friend offers grant site credit to both you and your friend, some may only extend it to the referrer.

Verifying the type or form of referral promotion is important, too, whether it be bonus bets or another variation of funds being added to your account. Bonus bets are great because they often have few restrictions, apart from the fact that using them as your stake means you don't get that amount back as part of your winnings.

Other terms and conditions referral bonuses may have include:

• Minimum deposit amounts
• Wagering restrictions (minimum odds of stake)
• Expiry periods
• Maximum referral limits

Of course, you'll also want to refer someone to a sportsbook with markets that person will enjoy.

On the subject of steering, auto racing fans can check out our top NASCAR betting sites and F1 betting sites.

Even though sportsbook referral bonus offers are beneficial and popular, they have limitations. For example, as a referrer, receiving a bonus depends entirely on the referee.

Referees can also determine whether or not you'll get the greatest possible value, as highlighted in the DraftKings referral bonus section above. Sometimes, you can simply get more value by taking the sign-up offer, which you may not be eligible for if you collect a referral promo. 

It's worth pointing out that you shouldn't see the rewards from these refer-a-friend bonuses as free bets. A free bet suggests you or your referred friend won't have to spend money. That's not the case with any referral bonuses I've encountered. 

With legal sports betting available in most U.S. states, the number of sportsbooks with referral bonuses is rising. Here's where you can find legal sportsbooks with refer-a-friend offers:

Responsible gaming is instrumental in creating a tailored sports betting experience that is safe and fun. Ensuring you're aware of the possible pitfalls associated with gambling and taking the appropriate steps to avoid them is vital.
