Start with a $20 Deposit
If you are looking to get a real piece of today’s NBA slate, this promotion is strictly available for new Polymarket customers. To claim your reward ahead of tonight’s tip-off, all you need to do is create your account and make an initial deposit of at least $20. Once that qualifying deposit clears, it will automatically unlock your $20 sign-up bonus.
This extra $20 bonus is the perfect tool for our betting strategy tonight. Remember, we’re in this together, and starting off with house money gives you a real chance to chase those bigger payouts. Just make sure you are 18+ and physically located in an eligible Polymarket state to grab this offer before the Celtics and 76ers hit the hardwood.
Buy Trades During Celtics-76ers, Lakers-Rockets
| Matchup | Moneyline | Probability |
|---|---|---|
| Boston Celtics @ Philadelphia 76ers | Celtics / 76ers | BOS 71.1% / PHI 28.9% |
| Los Angeles Lakers @ Houston Rockets | Rockets / Lakers | HOU 62.7% / LAL 37.3% |
If you want to use your $20 bonus to back the heaviest favorite on the slate, a winning ticket on the Boston Celtics would yield a $6.97 profit. On the flip side, I always love looking for a lucrative payout—if you trade that same $20 on the heaviest underdog, the Philadelphia 76ers, a victory would return a sweet $46.20 in profit. In addition to individual games, customers can make trades on teams to win the Finals.
