Best Sports Betting Sign-Up Bonuses

Caesars Sportsbook

Caesars Sportsbook

Caesars Sportsbook offers the largest sign-up bonuses in the country. The current welcome offer is named “Go Full Caesar.” It provides all new customers with first bet insurance of up to $1,250. If your first bet loses, you will get the money back as a free bet. This free bet has a 1x rollover requirement, and your winnings will then be eligible for withdrawal.

You will also get 1,000 Reward Credits and 1,000 Tier Credits when you sign up for a Caesars Sportsbook account. That makes it the best all-round welcome bonus on the market. There are lots of additional offers for Caesars customers too, including more than 50 daily odds boosts, profit boost tokens, free bets and a referral bonus worth $100.

Parent company Caesars Entertainment has been spending heavily on promotional credits since it got into the sports betting business. It bought William Hill for $4 billion in 2021 and converted the app to Caesars Sportsbook. The company is on a mission to turn it into one of the market leading sportsbooks in America, so it has launched very exciting promotions to appeal to new customers.

FanDuel Sportsbook

Fanduel Sportsbook

FanDuel is the No. 1 sports betting brand in the United States.

The current sign-up offer is a no-sweat first bet of up to $1,000. You can create a FanDuel account and put on a bet worth at least $10 to qualify. If it loses, FanDuel will refund you with up to $1,000 in bonus credits.

The bonus credits have a 1x playthrough requirement. This sign-up bonus is more flexible than rival offers. You can decide to use your credits on one bet, or you can split them into as many smaller bets as you like. When the 1x rollover requirement has been satisfied, FanDuel allows you to cash out your winnings. You will then be able to redeem additional bonuses, take part in free-to-enter contests and check out daily bet boosts.

You can wager $10 or more on any game, and BetMGM will issue a 100% rebate of up to $1,000 if that bet loses. The rebate will be paid as one free bet if it is smaller than $50, or it will be split into five if it is larger. Each free bet must be rolled over once before you cash out. You will then join the MGM Rewards program, and you will also receive additional promos, such as free bets, boosts and a referral offer.

The sportsbook is powered by Kambi, offering a polished user experience and a comprehensive selection of bets.

The BetRivers sign-up bonus is a second chance free bet of up to $500. If your first wager loses, you will be refunded with a free bet within 24 hours.

This sportsbook is powered by SBTech – a DraftKings subsidiary – and it offers a very accessible sports betting experience for desktop and mobile bettors.

This online sportsbook offers a risk-free bet of up to $250 for all new customers.

It is famous for launching several key live betting innovations over the years. It offers live streaming, early cash out, partial cash out and various other tools to make the in-play wagering experience exciting. 

Bet365 runs a very impressive “bet $1, get $200” sign-up bonus. You can make a deposit of $10 or more and then wager $1 on any sports event to qualify for this welcome bonus. When your $1 bet settles, Bet365 will credit your account with $200 in bonus funds. You only need to satisfy a 1x rollover requirement before cashing out.

Unibet is another European heavyweight on a mission to dominate the United States. A Swedish bookmaker created the business in 1997, and it is now a sprawling global empire with thousands of employees. The company has been renamed Kindred Group, but Unibet is its No. 1 brand.

One point to note is that Unibet created Kambi, the white-label provider. It was spun off as a separate business seven years ago, but Unibet’s sportsbook is still powered by Kambi tech, so the customer experience is very similar to that of BetRivers and MaximBet, which also use Kambi. Where Unibet stands out is with its bonuses, betting limits and customer service, all of which are excellent, and it has a vibrant online casino too.

Unibet also provides new customers with a risk-free bet. If you are in New Jersey, it will give you a $250 cash refund if your first bet loses. That means you can withdraw the funds immediately, with no need to complete any rollover requirements. In all other states, Unibet issues your refund in bonus credits – just like rival sportsbooks – and you need to roll them over 1x before withdrawing.


  • Very impressive risk-free bet bonuses
  • Trusted sports betting company with decades of experience
  • Simple, easy-to-use website and mobile app
  • Provides lots of helpful pre-game statistics


  • Offers the same user experience as fellow Kambi clients
  • Some point spreads could be a little sharper


WynnBet Homepage

This is the online sports betting and casino arm of the Nevada casino titan. It is one of the newer arrivals on the scene, having launched in 2020, but it is invested in some appealing promos to catch up with established rivals. The sportsbook is simple, covering fewer sports than rivals, but it has great odds and a reliable app.

In most states, WynnBET runs a “bet $100, get a $100 free bet” bonus for new users. You just need to bet $100 on any event at minimum odds of -120, and you will get a $100 free bet. It has a 1x rollover requirement. Once again, you can choose any market when using your free bet, but it must have minimum odds of -150.

If you are in a state in which WynnBET has an online casino, you will get a $50 free sports bet and $50 in casino credits for placing a $100 bet. In New York, it will only give new players a $5 free bet for placing a $100 wager, which is due to the high taxes sports betting operators must pay in the Empire State. After claiming the welcome bonus, you can redeem weekly offers, including free bets and reduced juice specials each Thursday.


  • Appealing sign-up bonus for all new customers
  • Often provides reduced juice betting lines
  • Lots of free bets available each week

Sports Illustrated Sportsbook

Sports Illustrated Sportsbook

888 Holdings launched this sportsbook after securing a deal with Sports Illustrated’s publisher. Its flagship online sportsbook, 888 Sport, struggled to compete with rivals like FanDuel, BetMGM and Caesars, so it is now taking a different tack. It runs on in-house tech, with competitive odds, and there are loads of tempting promotions.

SI Sportsbook offers a “bet $10, get $50 in free bets” sign-up bonus. You just need to sign up and place a $10 qualifying bet, and you will then receive $50 in free bets.

What are the best sports betting sign-up offers?

There are three main types of sports betting sign-up offers:

  • Risk-Free Bet | With this type of bonus for new users, if your first bet loses, then you get the money back. It is occasionally returned in cash, which you can immediately withdraw, but it is normally paid in free bet credits. They then need to be rolled over 1x before you can cash out the winnings.
  • Deposit Match Bonus | Online betting sites with this type of deposit bonus will match your first qualifying deposit with bonus money. The most common offer is a 100% deposit match bonus, but you may find a 50% deposit match or a 200% deposit match offer. A rollover requirement will be imposed on the bonus money.
  • Bet and Get | With these sports betting bonuses, you need to place a qualifying bet – either on any market or on a specific sport – to get free bet credits if you claim this type of sign-up bonus. Common examples include “bet $5, get $150” and “bet $10, get $50” offers. There are also “bet and win” sign-up bonuses, which only provide you with bonus credits if your qualifying bet is successful.

What are “terms and conditions?”

All online sports betting sites publish terms and conditions under their bonuses and ongoing promotions. You can read the terms and conditions of sports betting bonus offers to learn how to redeem the offer and what you then need to do before cashing out a profit. These are the main terms:

  • Minimum Deposit | Most sports betting sites require you to make a minimum initial deposit to qualify for the sign-up bonus. The minimum deposit limit is usually $10, but it may be $5 or $20 at certain sportsbooks.
  • Minimum Bet | A bettor has to make an initial wager to claim risk-free bet offers and “bet and get” bonuses. There is normally a minimum amount that you must wager, such as $10, to earn these types of bonuses.
  • Playthrough Requirement | All sportsbook bonuses will have playthrough requirements. This tells you the number of times you need to roll your bonus funds over before cashing out. They are also known as rollover requirements. Most sportsbooks have a 1x requirement, but there is a 5x playthrough requirement at DRF Sportsbook. If you had $200 at DRF Sportsbook, you would need to wager $1,000 before cashing out.
  • Minimum Odds | Some qualifying bets have a minimum odds stipulation. There may also be a minimum odds requirement on bonus funds when you are working on playthrough requirements.
  • Restricted Bets | There may be certain restricted bet types, such as a parlay bet or futures bet, when you are trying to satisfy rollover requirements. Free betting credits may also only be eligible for certain betting opportunities.

Sign-Up Bonuses vs. Deposit Bonuses

The terms “sign-up bonus” and “deposit bonus” are often used interchangeably to refer to the same thing: the welcome offer a bettor can receive after signing up at an online sportsbook or casino. A deposit bonus can refer specifically to a deposit match welcome offer, but some online sportsbooks refer to a risk-free bet as a deposit bonus.

Some online casinos refer to their sign-up offers as deposit bonuses to distinguish them from no-deposit bonuses, which award you site credit without requiring you to hand over any of your own money. It is also worth bearing in mind that some sportsbook promos for existing users may be referred to as deposit bonuses.

How To Choose The Best Sign-Up Bonus Offers

The best sign-up bonuses come with simple terms and low playthrough requirements. You can browse the various offers listed on this page and consider which bonuses appeal to your budget and playing style. Players with large bankrolls may opt for the offer of first bet insurance of up to $1,250 at Caesars, whereas more casual bettors might be tempted by the “bet $1, get $200” deal at Bet365 Sportsbook.

We encourage readers to sign up with multiple online sports betting sites and claim all the different sports betting bonuses for new users. You can then test out the different sportsbooks and find which sites offer a betting experience that you enjoy. It will also allow you to shop for the best lines before getting in on the betting action.

Is a crypto sign-up bonus better?

Licensed online sportsbooks do not accept cryptocurrencies. If you land on a sports betting site that accepts Bitcoin or a wide variety of altcoins for deposits and withdrawals, it is likely to be an unregulated, offshore sportsbook.

They may offer large deposit bonuses, but offshore sportsbooks tend to impose very high rollover requirements on the funds. You will also not be protected by state or federal law at those sites, so you may not get your money back if you win, which can spell bad news for bettors.

You’re much better off at a legal sportsbook that can provide a higher level of security. These sites accept traditional banking methods such as credit cards, debit cards, PayPal, bank transfers and eChecks.

FAQs – Sportsbook Sign-Up Bonuses

What are rollover requirements?

Online sportsbooks impose rollover requirements on your bonus money to prevent you from simply withdrawing it as soon as it arrives in your account. Measures like this are important to protect sites from bonus abuse and to ensure they can keep offering extra money for sports bettors.

It explains how many times you need to play the bonus funds through before your winnings become eligible for withdrawal in the form of cash.

The best sportsbooks only attach a 1x rollover requirement to their bonus funds, meaning you just need to play them through a single time, and you can then cash out your profits.

How do I withdraw bonus funds?

You will need to satisfy the wagering requirements attached to your bonus funds before making a withdrawal request. Betting credits need to be rolled over a certain number of times, and there may also be a minimum odds requirement.

When you have satisfied the wagering requirements, any remaining funds will move into your cash balance, and you can then request a payout. Visit the cashier section, select “Withdrawal” and follow the instructions to cash out your funds.

Why do online sports betting sites offer sign-up bonuses?

Sign-up bonuses are designed to attract new users to place bets on sports teams. There is intense competition for online sports betting market share, so major sportsbook brands offer sign-up bonuses to distinguish themselves from rival sportsbooks.

Do sign-up bonuses expire?

Most sign-up bonuses will eventually expire. If you see a welcome bonus you like, it is worth redeeming that offer before it disappears. Any bonus credits you receive from a sign-up offer will also expire if you do not use them in the specified timeframe.

For example, you may need to satisfy the wagering requirements within 14 days. If you fail to do so, the sportsbook will remove the bonus credits, rendering them forfeited.

Most common types of online sportsbook bonuses will expire after a certain period of time.

Can you redeem a sign-up bonus twice on the same site?

No, you can only redeem a sign-up bonus once on a particular site. If you claim a welcome bonus, you are precluded from any other welcome offers the site introduces – even if it launches a different sign-up bonus to the offer you previously claimed.

Sportsbooks will not tolerate the same customer signing up for multiple accounts with different details, and you will be banned if you are caught trying to do so. However, you can sign up with lots of different sites if you want to redeem several sign-up bonuses.

Long-term bettors can also receive additional bonuses from a site, though. Registration isn’t your only chance for bonus cash from online betting sites. Players can also benefit from odds boosters, VIP programs, and ongoing bonuses.
