Take the Reds or Guardians on Monday Night

Team	Win Probability
Cincinnati Reds	60.1%
Cleveland Guardians	39.9%

When I am analyzing a game like this and deeper situational trends, I look at the raw numbers. The Guardians enter the matchup with a slightly better 54-53 record compared to the Reds’ 49-55 mark. Despite Cleveland holding the outright edge in the standings, the consensus projections have established Cincinnati as the clear mathematical favorite at a 60.1% win probability as they host this showdown at Great American Ball Park.

Chase Burns is on the mound for the Reds, which has a lot to do with the probabilities. He is 12-1 this season with a 2.42 ERA.

How to Apply the Kalshi Promo Code for the Bonus

Getting started and locking in our welcome offer before the first pitch is incredibly straightforward. Follow my simple playbook below to successfully activate your bonus:

Create an Account: Register for a new account here by entering your standard personal information. You will also need to provide quick proof of identification to get verified—standard practice to keep the platform secure.
Enter the Promo Code: During the registration process, don’t forget the most important step: enter the Kalshi promo code WTOP15 to opt into the promotion.
Make a Deposit: Fund your new account with a first-time deposit of at least $1.
Start Trading: To fully activate and unlock your sign-up bonus, you just need to make $25 worth of trades on the platform. The beauty of this is that you do not have to risk a full $10 on a single trade. A cumulative sum of $25 across multiple trades (like predicting different outcomes for the Guardians vs. Reds game) will satisfy the requirement and trigger your bonus.
