Polymarket NBA Promo for Thunder vs. Spurs Game 5 on Tuesday
| Team | Probability |
| San Antonio Spurs | 41% |
| Oklahoma City Thunder | 59% |
From a payout perspective, backing the favored Oklahoma City Thunder would offer a smaller return if the market is pricing them near 68%. However, users who believe there is value on the underdog side could consider the San Antonio Spurs for a larger potential profit if they can steal Game 5 on the road.
For example, a user could apply a portion of their deposited cash to a Spurs spread-style market or another Game 5 contract if available. If the position wins, the return depends on the entry price and the number of shares purchased. If it loses, that position settles at $0, but the $50 bonus can still give users additional flexibility to explore other Spurs vs. Thunder Game 5 markets or active options later in the week.
Trade Other Tuesday Markets: NHL Playoffs and MLB
While Spurs vs. Thunder Game 5 is the featured NBA market, the welcome offer is not limited to basketball. New Polymarket users can use the $50 sign-up bonus on other event contracts across the platform.
Tuesday, May 26 may also feature NHL Playoffs markets, MLB regular season action, and other live event contracts. That gives users more ways to spread out their trading activity instead of relying on one NBA Playoff outcome.
