Top NBA Betting Promo Offers

While we are still away from pre-season matches, let alone the beginning of the season, it's never too early to start looking. Below you'll find the top NBA betting promos including a detail explanation on how these betting promotions work.

1. FanDuel NBA Betting Promo

FanDuel offers players one of the best sportsbook mobile apps, a DFS platform, a new player guide, and one of the best NBA betting promos.

Start your FanDuel Sportsbook experience by creating a new account, depositing a minimum of $5, and locking in your very first real-money wager of $5 or more and claim $50 in Bonus Bets, daily for the next 7 days. This one-time welcome offer is not conditional: regardless of the bet outcome, daily $50 in Bonus Bets is yours - amounting to a massive $350 in Bonus Bets for the full 7 days of betting. This reward is triggered automatically once you fulfill the wagering criteria; you do not need a FanDuel promo code to access the offer.

You'll have seven days to use your bonus bets. Unlike other NBA betting websites, your bonus bets aren't in predetermined chunks. Instead, you can use them however you like.

FanDuel's extensive range of NBA promos and exclusive offers makes it the go-to platform for basketball enthusiasts.

2. BetMGM NBA Betting Promo

Owned by the world-famous MGM Resorts International, BetMGM is recognized as one of the big contenders in the sportsbook market today. BetMGM has an impressive range of markets and promos, as well as a great mobile app with excellent graphics.

BetMGM's NBA promo is a second chance bet up to $1,500 in bonus bets if your first bet loses. This is perfect for riskier matches.

No matter how the match pans out, you'll either win your bet and collect your winnings or lose and get your stakes back in bonus bets. But let's not get ahead of ourselves—here's how to claim this promo.

To claim your BetMGM NBA betting promo, you'll need to register using the BetMGM promo code WSNSPORTS, deposit at least $10, and bet at least $5 on the NBA Finals or any other sports market. If your first bet loses, you'll get your wager stakes back in the form of bonus bets. The more you place on your first bet, the more you'll win or get back in bonus bets. Here's an example:

If you place a $500 bet on the Mavericks and lose, you'll get $500 in bonus bets. If you win, you'll collect your winnings but won't receive any bonus bets. It's a win-win situation. Keep in mind that your bonus bets are limited to $1,500, so even if you bet $1,800, you'll only get $1,000 in bonus bets. So, don't overdo it.

While we're on the topic of BetMGM we do have to mention their loyalty program, which is on par with the one offered by Caesars. These two definitely go big on promos and loyalty rewards. BetMGM loyalty rewards include BetMGM resort rewards as well as exclusive promo offers.

This isn't all; you also have ongoing promos like parlay and SGP boost tokens, as well as Free to play games. All of these combined make BetMGM a pretty good NBA betting website.

3. BetRivers NBA Betting Promo

BetRivers is an excellent NBA beginner sportsbook with user-friendly features and a wide range of NBA betting options, including live betting. New users can take advantage of a second chance promo of up to $500, $250, or $100, depending on their state. You can get up to $500 in IL, IN, LA, MD, MI, PA, and VA; up to $250 in CO and NJ; and up to $100 in AZ, IA, NY, OH, and WV.

To unlock this offer, simply use a BetRivers promo code SPORTS during the sign-up process.

BetRivers' second chance betting promo works similarly to others we've mentioned. You'll need to register your account, deposit at least $10, and place a minimum bet of $5 on any market available. If that bet loses, you'll get your wager back as bonus bets, up to the indicated maximum for your state. Bonus bets will be deposited into your account within 72 hours of the bet settling.

The BetRivers site regularly offers odds and profit boost promotions and features a loyalty program called iRush Rewards, which provides additional benefits and incentives for frequent users.

4. Fanatics NBA Betting Promo

For your first ten days on the app, it matches your daily qualifying bet in FanCash up to $100, which adds up to $1,000 if you bet each day. The catch is in that structure: you only reach the full figure by placing ten qualifying wagers on ten separate days, so it rewards a daily habit rather than one big deposit. Miss a day and you forfeit that day's match, but the remaining days stay live.

FanCash is the other thing to understand before you claim. It is Fanatics' own currency, not cash, and you convert it into bonus bets at a 1:1 rate or spend it on NBA gear in the Fanatics store. Converted bonus bets carry a 1x playthrough and do not return the stake, so the review pegs the real cash value of the full $1,000 at closer to $700. That makes the offer worth chasing for a bettor who plans to be on the app through the early stretch of the NBA schedule, and less so for anyone wanting a single basketball bet and a quick cash-out. To claim this bonus, just enter the Fanatics promo code WSNFAN when creating your account.

The FanCash match is the headline in most states, but Fanatics also runs a state-specific alternative you can take instead. The version available to you depends on where you are:

These alternatives change more often than the main offer, so we re-check them monthly.
