To unlock your $20 sign-up bonus, simply create your first account and make an initial deposit of at least $20. Once your account is successfully funded, the $20 bonus will automatically drop into your balance.

Take the Action to the Ice and the Diamond
While Tuesday’s NBA slate is where my primary focus is tonight, there is nothing better than having options. New Polymarket customers can seamlessly use this $20 sign-up bonus to trade on daily MLB matchups or intense NHL postseason action. If you spot a high-value angle on the diamond or a lock on the ice, your promotional funds are good to go.
NBA Games on Tuesday Night
| Matchup | Probability |
|---|---|
| Houston Rockets @ Los Angeles Lakers | HOU 64.1% / LAL 35.9% |
| Portland Trail Blazers @ San Antonio Spurs | SAS 83.6% / POR 16.4% |
| Philadelphia 76ers @ Boston Celtics | BOS 87.2% / PHI 12.8% |
Trading your $20 welcome bonus on today’s heaviest favorite, the Boston Celtics, would net a modest $2.00 in profit given their massive 87.2% probability to win. On the flip side, we can take a calculated risk on the heaviest underdog, the Philadelphia 76ers (12.8%). If they manage to secure a shock upset on the road, that same $20 trade returns a massive $130.00 profit.
Analyzing the statistics reveals exactly why Boston is such a dominant favorite tonight after a brutal 123-91 Game 1 rout. The Celtics boast a stellar 30.1 Net Rate and a 51.8% Total Rebound Percentage, vastly outperforming Philadelphia’s dismal -30.1 Net Rate and 48.2% success rate on the glass. Boston is also an incredible 14-3 when Jayson Tatum, who dropped 25 points in Game 1, plays.
Meanwhile, the slate’s most competitive fixture presents a fascinating angle. The Lakers, fresh off a 107-98 Game 1 upset where Luke Kennard hit five threes for 27 points and LeBron nearly secured a triple-double, offer a solid betting profile with an 11.2 Net Rate compared to the Rockets’ -11.2 mark.
However, Houston could command the flow of the game through the glass, bringing a dominant 55.7% Total Rebound Percentage against Los Angeles’ 44.3%. Even with Kevin Durant questionable with a bruised right knee, betting whales are aggressively backing Houston to bounce back. Depending on which metric you value more, both sides offer unique angles for your promotional trade.
