Team Moneyline (Implied) Win Probability
Chicago Cubs -130 56.5%
Arizona Diamondbacks +130 43.5%

Let’s talk strategy and look at the payouts. If we place a $25 trade on the favorite’s moneyline—the Chicago Cubs at -130—a winning ticket would return approximately $19.23 in profit. On the flip side, if you’re sniffing out an upset at Chase Field, backing the underdog Arizona Diamondbacks with a $25 trade at their +130 implied moneyline would yield a sweet $32.50 profit. There is truly nothing better than hitting on a home underdog!

When I’m handicapping which club is the better bet, I always start with overall season success. The Chicago Cubs bring a notably stronger record to the table at 75-56, giving them a clear mathematical edge over the 69-62 Diamondbacks. While we don’t have more granular betting trends—like recent moneyline records, performance specifically as a favorite or underdog, and home/away splits—available for this specific matchup, Chicago’s overall season success firmly supports their position as the consensus favorite. It’s a solid spot to put those trades to work.

How to Activate Your Kalshi Welcome Offer

Getting started and claiming your welcome bonus ahead of the Cubs and Diamondbacks game is a breeze. I’m placing these trades myself, so let’s walk through the exact steps together to unlock those bonus funds:

  1. Download the App: Search for and download the Kalshi app on your mobile device.
  2. Register Your Account: Create a new account by providing standard personal information. You will also need to provide proof of identification to verify your account is fully secure.
  3. Use the Promo Code: Be sure to enter the promo code MILE during the registration process to opt into the welcome offer.
  4. Make a Deposit: Fund your new account with a first-time deposit of at least $1.
  5. Place Your Trades: To activate the offer, you must make $25 worth of trades on the platform. The beauty of this structure is that whether you are predicting the outcome of tonight’s clash at Chase Field or exploring other markets, you do not have to make a single trade worth $25. A cumulative sum of $25 in total trades will fulfill the requirement and ensure your sign-up bonus becomes available.
