Once you have applied the Kalshi promo code WTOP and familiarized yourself with the terms, you are well on your way to unlocking that $25 sign-up bonus. The funds hit your account after you make $25 in trades on Kalshi’s prediction markets, which is incredibly easy to knock out on tonight’s MLB slate.
I’m already looking at putting my trades to work in Atlanta, where the 82-55 Braves host the 56-81 San Francisco Giants at Truist Park. With Bryce Elder throwing for Atlanta and Anthony Molina on the bump for San Francisco, this non-conference clash is a prime spot to use your new user offer.
To qualify, you must be a new customer, create your account, and make a first-time deposit of at least $1. Keep in mind that Kalshi is available in all 50 states and users must be at least 18 years old to play, giving plenty of us a real chance to get in on the fun.
MLB Games and Probabilities for August 31st
| Matchup | Moneyline | Probability |
|---|---|---|
| SF @ ATL | SF +169 / ATL -188 | SF 36.3% / ATL 63.7% |
| SEA @ BOS | SEA +147 / BOS -162 | SEA 39.6% / BOS 60.4% |
| MIL @ CHC | MIL -101 / CHC -110 | MIL 49.0% / CHC 51.0% |
| PHI @ ARI | PHI -121 / ARI +103 | PHI 52.6% / ARI 47.4% |
Let’s break down the board. If you want to deploy your $25 in trades on today’s heaviest favorite, look no further than the Atlanta Braves (-188). A winning $25 trade on the Braves’ moneyline returns $13.30 in profit—a solid, straightforward play. But there’s nothing better than hitting a juicy underdog, right? Backing the San Francisco Giants at +169 would yield a sweet $42.25 profit if they can manage the road upset.
For a more tightly contested matchup that I’m personally keying in on, consider the showdown between the Brewers and the Cubs. Milwaukee comes in with a clear advantage on the mound, boasting an elite 3.37 overall team ERA compared to Chicago’s 4.15 ERA.
However, when we look at situational hitting, the Cubs’ offense has been slightly more productive, logging 684 total RBIs this season compared to the Brewers’ 644. With the vig-free probability sitting at a near coin-flip (Chicago 51.3% / Milwaukee 48.7%), this is a fantastic, balanced market to help unlock your sign-up bonus.
