Trade $10 to Get $10 Bonus
If you’re looking to trade on this massive postseason showdown between the Oklahoma City Thunder and San Antonio Spurs, using the latest Kalshi promo code is the perfect way to start building your bankroll. Exclusively for new customers, this welcome offer hands you a $10 sign-up bonus just for getting into the action. To trigger the promo, simply create an account and make a first-time deposit of at least $1.
Once your account is funded, the $10 bonus unlocks as soon as you make at least $10 in total trades on Kalshi’s prediction markets. You can fulfill this requirement by trading on the Thunder vs. Spurs game, or you can diversify your portfolio.
Remember, Kalshi isn’t just for hoops—you can absolutely make trades on other sports like MLB and the NHL right now to meet your requirement. As long as you are 18 or older and present in any of the 50 US states, you’re good to legally join the fray and lock in this value.
Probabilities for Thunder vs. Spurs
When we’re handicapping prediction markets, we often deal in implied probabilities rather than traditional betting odds. Here is a look at the vig-free win probabilities for today’s matchup:
| Team | Probability |
|---|---|
| San Antonio Spurs | 52.95% |
| Oklahoma City Thunder | 47.05% |
If you want to use your Kalshi promo code on a straight-up winner, understanding these percentages is your key to a nice payday. A $10 trade on the favored San Antonio Spurs (with a nearly 53% chance to win) will yield a solid, safer return if they hold court at home. On the flip side, if we’re feeling bold and predict an upset, trading $10 on the underdog Thunder (hovering around 47%) will net a slightly higher profit if they steal a road victory.
To help us find the smartest trade, let’s look at a few key statistical categories where these teams clash. Oklahoma City holds a distinct advantage in overall scoring efficiency, posting a stellar 14.3 Net Rate (estimated points scored minus points allowed per 100 possessions) compared to San Antonio’s 11.7.
However, if you’re looking for where the Spurs dominate, it’s in the trenches: rebounding. San Antonio boasts a massive 53.1% Total Rebound Percentage, while the Thunder lag behind with a 50.1% rate. Whoever controls the glass today might just control the outcome.

Here’s a pro tip from me to you: you don’t need to place a single trade worth $10 to qualify. We can split up our predictions however we see fit. Whether you want to make smaller trades entirely on the Thunder vs. Spurs game, or mix in some NHL and MLB action, it all counts. As long as the total sum of your trades reaches $10, your $10 sign-up bonus will hit your account, giving us even more ammunition for the playoffs.
