We’ve got a fantastic slate of baseball today, and there’s nothing better than securing a nice pay day while watching the action. If you're looking to elevate your handicapping strategy beyond simple win/place bets, tapping into prediction markets is an incredibly smart move. Fortunately, there are multiple apps to use, and I've rounded up the best MLB prediction market promo codes to help us build our bankrolls.
For today's exciting matchups—like the massive clash between the Atlanta Braves and Chicago Cubs—new Kalshi customers can use the Kalshi promo code TSNEWS to get a $25 bonus that is unlocked after making just $25 in trades. This excellent welcome offer can be deployed on today's games, later this week, or straight through the upcoming playoffs.
Leading MLB Prediction Market Promo Codes
While we are highlighting Kalshi's outstanding welcome bonus today, I'm a big believer in spreading the wealth across a few platforms to maximize our starting capital. Here is a breakdown of the top MLB prediction market promo codes available right now:
| Kalshi | Deposit $10 for a $50 bonus | |
| Polymarket | Trade $25 for a $25 | |

Making Trades on Today's MLB Matchups
If you trade your initial $25 on today's heaviest favorite, you'll secure a smaller, high-probability return. However, if you decide to back the heaviest underdog on the board and they pull off the upset, that same $25 trade will yield a significantly larger pay day.
In our featured matchup between the 88-win Atlanta Braves (ATL) and the 84-win Chicago Cubs (CHC), we have a classic pitching vs. hitting contrast. The Braves boast a strong away pitching staff with a 3.617 ERA, compared to the Cubs' 4.180 home ERA. However, Chicago's offense is potent at Wrigley Field, tallying 806 runs and a .771 OPS, while Atlanta has plated 696 runs with a .721 OPS on the road.
Looking at the New York Yankees (NYY) visiting the Minnesota Twins (MIN), the 87-win Yankees bring an elite away pitching staff featuring a stellar 3.221 ERA, significantly outpacing the Twins' 4.709 home ERA. Offensively, they are deadlocked on paper: the Twins have scored 686 runs with a .722 OPS at home, while the Yankees have scored 685 runs with an identical .722 OPS on the road. Keep a close eye on these statistical trends to lock in value once the odds are posted!
