The NBA Finals continue on Monday with Game 5 between the Dallas Mavericks and Boston Celtics as the latter attempts to lock up the series victory. Boston jumped out to a quick 3-0 lead, but the Mavs stormed back in Game 4 for a blowout win. If you're looking to bet on Monday's action, you can claim various betting promos.

These promos are offered to new users. If you haven't previously registered at some of the top sports betting sites in the industry, you can do so with these sign-up bonuses. This includes online sportsbooks like FanDuel, DraftKings, and bet365. You can apply these betting promos to any event, including the ongoing Stanley Cup Final or MLB season, along with the NBA Finals.

Best NBA Finals Betting Promos


FanDuel's sign-up bonus in most states unloads a "bet $5, get $200 if your first bet wins" offer. This structure is a bit different from other Bet & Get offers, considering your first bet must win to recover a bonus. If you're in Massachusetts or Ohio, you will receive $300 in bonus bets instead of the $200.

The offer doesn't have any minimum odds requirement, so you can place your first bet at whatever odds you want. However, we strongly advise placing your first wager at short odds.

For example, a good option is Celtics moneyline (-200). If I placed a $10 bet on Boston, a win would only return $5 in profit, but I'd also receive $200 in bonus bets. If I lose the bet, I get nothing, making it imperative that I win my initial wager.


At DraftKings, you can claim a $150 Bet & Get offer. Deposit and place your first bet for $5 or more to get back $150 in bonus bets, regardless of the bet's outcome.

Suppose I place my first bet on Luka Doncic Under 7.5 assists (+120) for $10. If the bet wins, I receive $12 in profit and $150 in bonus bets. If the bet loses, I don't get any profit back but still get the $150.


bet365 is the only sportsbooks where you can get a choice between two sign-up bonuses by using the same bonus code TOPACTION. Your choice will be between a $1K first-bet safety net and a $150 Bet & Get.

The first-bet safety net works by covering your first bet if it loses, up to $1K. For example, if I placed a $200 first bet at +110 odds, a win would get me $220 in cash profit. If the bet lost, I'd get $200 in bonus bets back that must be used within seven days.

The $150 Bet & Get works standardly. Place your first bet for $5 or more at -500 odds or longer and receive $150 in bonus bets no matter the outcome.

Fanatics Sportsbook

Fanatics Sportsbook's welcome offer unlocks ten days of daily bet matches of up to $100 each, totalling $1K in value. The offer functions by matching your initial wager each of the first ten days after sign-up, as long as it is -200 odds or longer. If you're in Ohio, you can lay claim to a $1K first bet insurance promo instead.


BetMGM has a pair of bonus codes you can use on Monday. When you register for a new account using the BetMGM bonus code TOPTAN1600, you'll earn a 20% deposit match of up to $1.6K in sports bonus. If you use TOPACTION instead, you'll earn a $1.5K first bet insurance offer.

The 20% match comes with a 10x rollover requirement. For example, if I make my initial deposit for $2.5K, $500 in bonus bets are up for grabs. However, the rollover means I must wager through $5K to unlock it.

The first-bet insurance offer covers your first bet if it loses, up to $1.5K.

Caesars Sportsbook

The Caesars Sportsbook promo codeACTION41000 earns $1K in first bet insurance for Monday's Game 5 of the NBA Finals. Place your first bet, and receive a bonus bet back if it loses. Suppose I place my initial wager for $500 on the Mavericks moneyline (+210). If the Mavs win, I receive $1,050 in profit. If the Mavs lose, I get back a $500 bonus bet that must be used on a single wager within 14 days of receipt.
