The Cardinals and Diamondbacks both find themselves fighting their way into the National League wild card picture for their Thursday afternoon makeup game in St. Louis. Cardinals-Diamondbacks bettors can use the Kalshi promo code NYPMAX to trade $25 and get $500 when they sign up.

Brandon Pfaadt (4-1, 4.58 ERA) takes to the mound for Arizona against St. Louis’ Michael McGreevy (4-7, 2.92 ERA).

How to use the Kalshi referral code

Once users have signed up, they’ll enter the Kalshi promo code NYPMAX, verify their account information and complete at least $25 in trades to qualify for the $500 bonus.

Prediction markets let people trade contracts based on the outcome of future events, with prices moving as traders reassess the likelihood of each result. Those prices reflect the market’s implied probability — for example, a contract trading at $0.35 suggests traders collectively believe there’s a 35 percent chance that outcome occurs.

What our Post expert thinks about Diamondbacks vs. Cardinals

The Diamondbacks, priced as -110 underdogs, just took last week’s series 2-1 against the Cardinals. Both pitchers started in that series, each making for sound outings. 

McGreevy didn’t factor into the decision in his last start on Friday against the Diamondbacks, but he delivered his fourth straight quality start by allowing just one earned run over 6 ⅓ innings. The right-hander has become a reliable arm for St. Louis, now having recorded seven quality starts in his last eight outings.

In Pfaadt’s last start, he improved to 4-0 since returning to Arizona’s rotation, allowing two runs over 5 ⅓ innings to earn the win against the Cardinals. The right-hander has surrendered just five earned runs across his last four starts.


Must be 18 years or older and have a legal, U.S. residential address within the applicable state, D.C., or U.S. territories. Not available in AZ, IL, MA, MD, MI, MT, NV, and OH.
