Sportsbook referral bonuses are easy to claim when you follow our step-by-step guide:

1. Register 

Your first step is to create an account at the sportsbook you're using for the referral. Click any of the links on our page to get started.

2. Find and share your unique referral link

Once you create your sportsbook account, you can find your unique referral link by going to the promos page or the referral program page. From here, share your referral link to any interested friends or family members.

3. Read the terms and conditions

Both you and the friend you're referring must be up to speed on the terms and conditions of the referral offer. There are often instructions that both people need to follow to claim their referral bonus correctly.

4. Get and use your bonus

Once you meet all of the expected wagering requirements of the referral offer, both you and your friend will receive the referral bonus. It's now time to go and use your bonus bets on a wager.

Referral bonuses require you to complete some steps. Finding your unique referral link or code, understanding the wagering requirements, and knowing how long before bonuses expire are all key pieces of information.

How to find and share your referral link

To find and share your referral link, follow these steps:

1. Log in to your account.
2. Locate the referral section.
3. Copy your unique link or code.
4. Share with your friends.
5. Ensure they meet the deposit and wagering requirements.
6. Track your referrals, if the sportsbook allows.

Requirements for the referred user

As the referee, you must complete some requirements to claim a referral bonus from a friend or family member. Specifically, you must meet the wagering requirements by depositing and wagering a minimum amount, which differs from sportsbook to sportsbook.

Timing and expiry of bonuses

Most referral bonuses expire 30 days after the referral sets up their sportsbook account. The sportsbook operators have this in place because it encourages timely action, manages their operating costs and liabilities, and maintains fairness and integrity.

When you successfully refer someone to a sportsbook, both of you will often receive their reward, usually in bonus bets, within 48 hours of completing all the requirements. With licensed betting sites, you don't have to wait long to get your rewards.

Anyone who is a new or existing user at a sportsbook is eligible for a referral bonus. We outline some of the eligibility requirements for both the referrer and the referee below.

As the referrer, you must:

• Have an existing, active, and verified betting site account.
• Have made a deposit or placed bets within a reasonable timeframe (usually the last 60 days).
• Find and share your unique referral code.

As the referee, you must:

• Be a new user at that sportsbook.
• Use your referral's unique link to sign up at the sportsbook, ensuring that the referral is tracked correctly.
• Be located in a state/location where the sportsbook legally operates and be of the legal age in that state.

Referral bonuses typically come in the form of bonus bets; however, sometimes they will come in the form of rewards program credits, like with Caesars Sportsbook. The reward itself will vary from sportsbook to sportsbook, but typically ranges from $50 to $100.

Claiming referral bonuses is an easy way to earn extra sportsbook rewards. Both you and your friends benefit when they sign up, and you can send multiple referrals for additional bonuses. There may be some limiting terms and conditions, but these bonuses should be on every bettor’s radar.

Repeatable rewards

In the table above, we note that referral bonuses can be claimed multiple times. Compared to a sportsbook's promo welcome offer, which you can only claim once, you can claim a referral bonus numerous times. 

Most sportsbooks have different amounts of referrals they allow, usually in a month-long period. For example, DraftKings allows five total referrals per offer period, whereas BetMGM gives you up to 20 referrals per month.

When referral offers make sense

Referral offers make sense almost all of the time, but there are some best-use cases we can explore. Some examples include, but are not limited to:

• Stacking on top of a sportsbook welcome offer.
• Before a major sporting event like NFL or March Madness beginning.

Major sporting events

There is typically a surge in sportsbook sign-ups at the start of major sporting events. The NFL is a prime example, with first-time deposits typically spiking in September when the season begins. 

Welcome offer stacking

Since you are allowed to claim both a welcome bonus and a referral bonus as a new user, some people will join a new sportsbook and then invite friends onto that sportsbook with their referral code, claiming both the welcome offer and the sportsbook referral bonus. For example, if you claim the BetMGM welcome offer and the referral bonus, you can claim up to $1,600 in bonus bets at the maximum value. 

While we've highlighted the most important referral bonuses for you, there are also other sportsbooks with referral bonuses you should consider. 

ESPN BET referral bonus

You and a friend can each earn $50 per referral at ESPN BET when your referral meets the wagering requirements, which are making an initial deposit of $50 and betting $25+.

You and a friend can each earn $50 when you follow these steps:

• Have your friend use your unique ESPN BET referral link to create an account.
• Once your friend deposits $50 and wagers at least $25, you both will receive a $50 bonus bet.
• This bonus bet expires seven days after it is received.

BetRivers referral bonus

BetRivers Sportsbook's Refer-A-Friend program will pay you and your referred friend a $100 bonus bet when they deposit and wager at least $50 within the first 30 days of opening their account.

To claim your BetRivers referral bonus, complete the following steps:

• Locate the Refer-A-Friend form on the promotions page of the BetRivers website.
• Your referral must create a new account using your BetRivers referral link.
• Once their account is created, your friend must deposit and wager at least $50 within 30 days of the account's creation.
• Once the wagering requirements are met, you both will receive a $100 bonus bet.
• This bonus bet will expire 30 days after issuance.

Most sportsbooks have a cap on how many referral invites you can successfully convert over a month-long or offer period, so here are some tips to maximize referral bonuses while adhering to the rules.

📱 Share links via chat or social media

When you share a referral link online or on social media, you expand your contact network beyond your usual group of friends. You can potentially attract extra sign-ups this way from people you wouldn't have usually reached out to personally to share your link.

⏳ Time referrals strategically 

Timing is always key. Send out your referral link during key sporting events, such as the lead-up to March Madness or before the NFL playoffs. Betting interest spikes during times like these, and more people are willing to sign up to bet than on a random weekend in July when there are not many major sporting events. 

📝 Make sure everyone understands the terms and conditions

The more people you share your referral link with, the more people you'll need to make sure understand the terms and conditions so that you can correctly convert your referral link into bonus bets or Reward Credits.

It remains a priority that you put an emphasis on gambling responsibly, no matter whether you're redeeming sportsbook referral bonuses or betting long-shot parlays.

Make sure to check the terms and conditions when helping a friend with your referral link, so you and they understand what's required to qualify. Also, always stay within safe betting limits and prioritize your welfare when wagering on sports.
