Polymarket NBA Promo for Spurs vs. Thunder Game 1 on Monday
| Team | Probability |
| San Antonio Spurs | 33% |
| Oklahoma City Thunder | 68% |
Strictly looking at payout, using the bonus on the favored Oklahoma City Thunder yields a small return. However, if you think there’s value on the underdog, trading on the San Antonio Spurs provides a larger profit if they can steal a game on the road.
Let’s say you go beyond the main market and use the $20 deposited cash on the Spurs +6.5 at 50¢ per share. If you win, you get $19.40 in profit plus the cash back for a $39.40 total payout. If you lose, your position goes to $0; however, you still have the $50 bonus to try different Spurs vs. Thunder Game 1 angles or any markets this week.
