Kalshi MLB Promo for Sunday, May 31

The weekend rivalry series at Busch Stadium is locked at 1-1 after two tightly contested, contrasting matchups. The Cardinals took Friday’s opener 6-5, holding off a late Chicago rally thanks to home runs from Nelson Velázquez and Iván Herrera. The Cubs fired right back on Saturday night with a commanding 6-1 victory behind seven dominant innings from Ben Brown. Pete Crow-Armstrong fueled the offense, going 4-for-5 and falling just a triple shy of the cycle to set up a massive rubber match.

Tonight’s Sunday Night Baseball finale features a left-handed matchup between Jordan Wicks and Matthew Liberatore. If you are trading the game on Kalshi, the 1¢ to 99¢ contracts allow you to scalp quick price fluctuations early on. With both pitchers capable of giving up quick runs, you can buy a team low if they fall behind in the first inning. Instead of holding until the final out, you can sell your position for an early profit the moment the live win probability swings.

Other Markets on Kalshi: MLB and More

Your $10 bonus is not limited to Cubs vs. Cardinals. After completing the initial $10 in trades and receiving the Kalshi bonus, users can also explore other markets on Sunday, May 31.
