Bets that use other promotions like Profit Boosts or other Bonus Bets aren't eligible for the introductory offer.

Who is this promo for?

This is a unique offer which gives bettors profit boosts on future bets rather than offering bonus bets. This is not a guaranteed win promotion, so the customer is not guaranteed any cash winnings or bonus bets throughout the promotion. 

These profit boosts expire within 14 days after they are granted to the customer.

2. 10 100% profit boosts will be awarded after the placement of a $1 wager.

Fanatics Sportsbook promo code: Up to $1,000 in No Sweat Bets

Just click CLAIM BONUS to get started. No special Fanatics Sportsbook promo code is required during registration. 

To maximize the full value of the promotion, a customer must repeat $100 bets for the first 10 days after the creation of a new account. 

Who is this promo for?

This offer should appeal to the moderate-sized bettor who is willing to bet more, with the worst-case scenario being that they receive a bonus bet if their wagers lose each day.

How the Fanatics Sportsbook promo code works

1. Minimum deposit: $10
2. No promo code required
3. Must be 21 or older and in a state where Fanatics Sportsbook legally operates.
4. Place a daily first bet of at least $1 on any market with odds of -500 or longer (e.-450, -300, +150).

This means you can earn up to $1,000 in bonus bets over the promo period.
5. Bonus bets are credited to your account within 72 hours of your qualifying wager settling as a loss.
6. Each bonus bet expires seven days after issuance.
7. After the initial qualifying bet on Day 1, you must opt-in to the promotion each day before placing your qualifying wager to continue receiving bonus bets.

BetMGM Sportsbook promo code: SPORTSLINE for up to $1,500 in bonus bets

You can click CLAIM BONUS and use BetMGM promo code SPORTSLINE to unlock this offer. New customers can sign up and receive up to $1,500 in bonus bets if their first bet doesn't win. In other words, if your first wager loses, you will get the same amount back in bonus bets, up to $1,500.

New users can deposit and wager a minimum of $10 for their first bet, and if it wins, they will receive the stake + winnings in cash. If the bet loses, you will get a bonus bet for the amount of the losing bet stake you placed. The maximum bonus bet is $1,500. The bonus bet expires after seven days.

Who is this promo for?

Of the sportsbook promos and bonus codes referenced on this page, BetMGM is the only one that offers a promotion that caters to both smaller and larger bettors alike. With the No Sweat Bet being up to $1,500, smaller and larger bettors can take a big swing with their first wager, knowing that the worst case scenario is receiving a bonus bet in the same amount. Though the bonus bet doesn't equate to cash, it essentially gives the customer two chances to hit their first bets and accumulate cash in their account.

How the BetMGM promo code works 

1. Promo code: SPORTSLINE
2. New BetMGM customers only
3. Must be 21 or older and located in an eligible state where BetMGM legally operates.
4. Bet amounts: Wagers Under $50: If your first bet is less than $50 and it loses, you'll receive a single bonus bet equal to the wagered amount. Wagers of $50 or More: For first bets of $50 or more that lose, the refund is divided into five equal bonus bets, each worth 20% of the initial wager. For example, a losing $200 bet would result in five $40 bonus bets.
5. Bonus bets expire seven days after issuance.
6. When placing a bet using bonus funds, only the winnings are returned to you; the bonus stake is not included in your returns.
7. Minimum $10 deposit required for eligibility
8. No minimum odds requirement.
9. Remember: Bonus bets are awarded only if first bet loses; if it wins, the profit may be kept, but no bonus will be awarded.

The bonus bets expire after seven days.

bet365 promo code: Bet $5, get $150 in bonus bets win or lose

The first of the two promos offered is a bet-and-get sign-up bonus. Bet365 is offering customers a bet $5, get $150 in bonus bets promo. You don't have to win your first bet to get the bonus bets. Just deposit at least $10, and wager at least $5 on any market with odds -500 or longer (i.e. -110, -200, -350, etc.). 

If you win your first $5 bet, you will receive the stake + winnings in cash, as well as the $150 in bonus bets. If the bet loses, you will just get the $150 in bonus bets from bet365. 

If your first bet of $5 does not settle within 30 days after registration, the offer will be forfeited. So we do not advise betting futures (odds to win the championship) for this offer throughout most of the year.

How the bet365 promo code works

1. Promo code: SPORTSLINE
2. New bet365 customers are eligible for this promo if they claim it within 30 days of registration.
3. $10 minimum deposit
4. Minimum $5 bet on any sports market with odds of -500 or longer.
5. Bet must settle within 30 days of claiming the offer.
6. Fully cashed out bets, event-specific bonus bets, live in-game bets settled as a push, and bets deemed no action do not count towards the qualifying bet. 
7. Once your qualifying bet settles, you will receive $150 in bonus bets. These bonus bets are non-withdrawable and must be used within seven days of being credited. 
8. The bonus bet amount is excluded from any returns; only the winnings from these bets will be added to your withdrawable balance.

Any bonus bets expire after seven days.

Types of sportsbook promos

Sportsbooks offer several promotions and incentives for both new and existing users. Here is a list of each type of sports betting welcome offer and how they work:

Sign-up bonus

When customers are new to a sportsbook, they are offered sign-up bonuses as new users. These include bet-and-get bonuses (for example: bet $5, get $200 in bonus bets), No Sweat Bets (bonus bets back if your bet loses), and more. It is highly recommended that new customers take advantage of these offers, as they are a good way to try out the sportsbook and kickstart your sports betting bankroll. 

Bonus bets

Sportsbooks give out bonus bets for different reasons, including new customer bonuses, deposit matches, losing No Sweat Bets, and loyalty incentives/contests. Customers can also redeem loyalty points for bonus bets on BetMGM, Caesars, Fanatics and DraftKings. Bonus bets have no cash value and must be wagered before any winnings can be withdrawn in cash.

If a $100 bonus bet is played at +200 odds, the player would only receive $200 in winnings if the bet hit and would not receive the bonus bet stake. By comparison, a winning $100 bonus bet at +200 would pay out $300 ($100 stake + $200 profit). These bets usually expire seven days after they are awarded.

Deposit match

Some sportsbooks will occasionally offer deposit matches as their new customer promotion. They might offer up to a 100% deposit match, and the maximum amount match varies. The deposit match may come in the form of cash or bonus bets.

If this deposit match is in cash, rollover requirements may be in effect so that money cannot be withdrawn until the bonus has been wagered through at least once (if not more, as specified by sportsbook rules).

No Sweat Bets

This type of sportsbook promo simply means you will get bonus bets back if your bet loses. This type of promo is also sometimes called a "safety net" at bet365. 

Reload bonus

Existing customers will occasionally receive offers from sportsbooks to re-deposit money into their accounts. To incentivize doing so, a sportsbook will give bonus bets matching up to a percentage of the deposit. FanDuel, BetMGM and Fanatics have given out a 50% deposit match to some customers, meaning if a player deposits $100 in cash, they would receive $50 in bonus bets.

Player referrals

Sportsbooks will offer incentives for referring other players such as friends or family. Users will receive a matching bonus bet up to the specified amount depending on how much the referral deposits. Additionally, some sportsbooks may reward both the referrer and the referred player with bonus bets or account credits, creating a win-win situation for both parties.

No deposit bonus

This type of offer provides users with bonus funds or bets without needing to make an initial deposit. It allows players to explore a sportsbook at no cost but is rarely available among the top sportsbooks in the US.

Odds boosts

Odds boosts are a common practice at most sportsbooks. Users can get an enhancement to the odds and potential winnings to incentivize them to bet on a specific game or parlay.

For example, if a sportsbook combined the Wildcats -3 and Over 145.5, generally the odds would be around +260. With an odds boost, the sportsbook might alter the payout to +300. There may be limits on the maximum bet allowed for these odds boosts.

Profit boost

Profit boosts are the most common form of promotion, and are found on most sportsbooks. Profit boosts are usually tied to parlays or same-game parlays and boost the potential winnings by a percentage. Let's say your three-leg same-game parlay is +500 and DraftKings is offering a 50% bonus for that exact bet. The new odds for your bet would be +750, though the maximum stake is always capped.

Loyalty/VIP programs

Most of the best sportsbooks have loyalty or rewards programs where bettors can build up points or credit with every bet they make, and use those points for bonus bets or other prizes.

Fanatics, DraftKings, BetMGM and Caesars offer the most comprehensive loyalty programs, allowing players to earn credits and tier credits for each bet they make. Tier credits increase your status for the current and following years, increasing the benefits you receive from those sites. Regular credits are redeemable for bonus bets and other perks such as hotel stays, merchandise, or other entertainment benefits. 

At Fanatics Sportsbook, each bet earns FanCash, which can be redeemed for bonus bets or for use at the Fanatics merchandise shop. 

For those customers who bet larger sums more often, they will likely be given a VIP host, which comes with additional benefits and incentives such as bigger bonus bets, tickets to sporting events, and travel perks. Long-term winning bettors typically do not get VIP perks. 

Contests

A contest on a sportsbook is another form of betting that you can play. Generally, you're asked to bet on a certain event happening, and whoever gets it right or gets closest will get a percentage of the contest pot. 

Contests are more frequent on DraftKings than the other sportsbooks. For example, its "King of the Court" promotion entices customers to place a $5 or more wager on certain NBA player markets for that day. If the player has the highest points + rebounds + assists total on the given day, the sportsbook will give them a share of $1 million in bonus bets, depending on how many other customers got the player correct in the contest. These are further incentives to make the customer's betting journey that much more entertaining.

What to look for in sportsbook promo code details

While it is recommended to be familiar with a promo's full terms and conditions, there are certain things we generally look out for.

Maximum bonus value

If you claimed the full extent of the promotion, how much would you get in bonus bets? The bet-and-get promotions (DraftKings, FanDuel, bet365) are best for the introductory player sampling out the sportsbook's menu, especially if their bets are centered around the big game(s). The maximum bonus value on these, however, is generally low. Rarely will you have a "bet-and-get" where you can bet $5 and get more than $300 in bonus bets.

Medium bettors might prefer Fanatics' no-sweat promotion over 10 days, where they are more likely to take chances with parlay bets to make more money. Larger bettors are most likely to prefer BetMGM's No Sweat Bet up to $1,500, using the bet on a spread or total of their choice (more conservative compared to parlays).

The maximum bonus value on a promo like BetMGM's is much higher, but you'll have to actually wager that much to claim it.

User investment

This refers to how much a bettor needs to bet to claim the promotion. On "bet-and-get" style promotions, the user investment is usually $5 or $10. With first bet insurance or other uniquely structured promotions, the user investment can be as high as whatever the sportsbook sets as the maximum. On Fanatics Sportsbook, for example, that would be $1,000.

Playthrough requirements or odds restrictions

Some sportsbooks require the initial bet(s) to be placed on markets of -500 or greater (-400, -300, -200, -110, etc.) though the bet and get offers don't come with those restrictions. A customer must win their wagers to be able to withdraw cash in their account. They cannot withdraw bonus bets.

Bonus expiration date

It's common across the industry for bonus bets to expire after seven days, though you may come across a longer or shorter expiration. The new customer needs to use their bonus bets before expiration to maximize the value of these offers.

Sportsbook promos and bonuses by sport

In many cases, specific promos are offered to a given sport. Here are a few examples.

Football

In the fall and winter, sportsbooks lean on profit boosts and No Sweat Bets to entice football bettors. For primetime NFL games or notable college football games, same game parlay bonuses are common. Weekly NFL touchdown parlay profit boosts have been a staple on FanDuel and DraftKings.

A football-specific promotion you can find is "Pro Football Second Chance" on BetMGM. With these promotions, you can bet on a player to score the first touchdown of the game, and you'll get your stake back in cash if the player you bet on doesn't score first but does score at some point in the game.

Basketball

Similar to football, profit boosts and No Sweat Bets are common in basketball markets, though sportsbooks tend to focus on nightly action vs. one particular game. Boost builders on DraftKings, FanDuel and bet365 allow you to add more percentage profit boost to your bet for every leg added to the parlay.

Baseball

Single-game SGP profit boosts for the primetime or playoff games are common, but home run promotions have been a hit on FanDuel.

For the last several years, it offered the "Dinger Tuesdays" promotion, where a customer would bet a minimum of $25 on one player to hit a home run and they would receive $5 in bonus bets for the combined number of home runs by both teams in that game. The maximum return on that bet would be if the player homered (stake + winnings) and a bonus bet for home runs in that contest.

Hockey

Similar to the first touchdown insurance for football, you might find first goalscorer insurance in hockey betting. If the player you bet on to score the first goal doesn't, but still scores a goal later in the game, you'll get your stake back.

Sportsbook promos FAQ

Which sportsbook has the best promo?

The best introductory promo is relative to what the customer is looking for in terms of their betting style. For larger bettors, they might appreciate BetMGM's No Sweat Bet up to $1,500. The smaller bettors who are sampling out sports betting might be more drawn to FanDuel and DraftKings' bet $5, get $200 offer.

Do all sportsbook bonuses require promo codes?

No. Only three of the six sportsbooks mentioned in this article require promo codes: SPORTSLINE for BetMGM, SPORTSLINE1000 for Caesars, and SPORTSLINE for bet365.

When do I enter the promo code in the registration process?

The promo code will be required where prompted at signup before your registration is confirmed.

Can I claim more than one welcome offer?

You can claim one welcome offer per sportsbook. If you've already registered with a sportsbook, you won't be able to claim any new welcome promotions they offer.

How do sportsbook bonuses work?

It depends on the offer itself. Each sportsbook has requirements for how much to deposit, how much to bet initially, what the minimum odds are on the first bet, and how much in bonus bets or No Sweat Bets a player can receive.

What are the playthrough requirements for sportsbook bonuses?

The first bet must be settled for customers to receive their initial bonus or winnings. Bonus bets are equal to $0 cash and must be played through in order to gain cash from the winnings.

What is a sportsbook bonus?

A sportsbook bonus is an incentive for new customers to deposit with that operator. Bonuses cannot be cashed out until they are played through.

Can you withdraw sportsbook bonuses?

No. Bonuses must be played through at least once before withdrawal options are available. That applies to bonus bets as well.

What are bonus bets and how do they work?

Bonus bets allow you to make a wager as normal but instead of the stake being included in your winnings, they are of $0 cash value.
