By signing up here with the Kalshi promo code TSNEWS, new customers can unlock a $25 bonus after making $25 in trades.

This introductory bonus gives us a real chance to build our bankroll on today's matchups—like the powerhouse Los Angeles Dodgers (75-51) taking on the Colorado Rockies (50-75)—or any other MLB game on the schedule this week.

Details of the Kalshi Promo Code TSNEWS

This promotion is exclusively for new Kalshi customers looking to step beyond traditional sportsbooks and explore the platform's unique prediction markets. First, make an initial deposit to fund your account. Then, your $25 sign-up bonus will be successfully unlocked once you've made $25 in qualifying trades on their prediction markets.

Whether we are eyeing the San Diego Padres (67-59) battling the New York Mets (57-69) at Citi Field, or the Miami Marlins (64-62) visiting the Philadelphia Phillies (68-58), this bonus gives us a serious head start on the action.

MLB Probabilities Today

When we are handicapping today's board, Kalshi's prediction markets give us a clear look at implied win probabilities. Here is how today's biggest games are shaping up:

If I'm looking at how to deploy my $25 in initial trades, we have some interesting options. You could back today's heaviest chalk—the Philadelphia Phillies at a dominant 67.9% probability—for a steady, lower-risk return. On the flip side, if you love taking a flier on the slate's biggest underdog, trading your capital on the Miami Marlins (32.1%) to pull off a road upset is where you'll find a much larger potential payout.

When searching for the best spots on the board, comparing team statistics is exactly how we find our edge. Take the matchup between the Seattle Mariners and Milwaukee Brewers. Milwaukee holds the clear upper hand on the mound with a stellar 3.456 team ERA, effectively shutting down opposing hitters better than Seattle's 3.848 ERA.

Offensively, the Brewers shine brighter too, hitting .250 with a .727 OPS compared to the Mariners' .230 average and .687 OPS. That 58.8% probability for Milwaukee starts looking like a very solid position.

Another tight contest features the Padres visiting the Mets. San Diego is a narrow road favorite (51.7%), and the numbers show exactly why they hold that slight advantage. The Padres sport a .703 team OPS and a 4.067 ERA, just barely edging out New York's .696 OPS and 4.068 ERA. This projects to be a highly competitive game, making it a great spot to look for value in the market.

Create Your Account with the Kalshi Promo Code

Securing your welcome offer is a quick and straightforward process, so let's get you set up.

First, register for a new account here. During the registration process, you will be asked to provide standard personal information and supply proof of identification to verify your identity. Most importantly, make sure to enter the Kalshi promo code TSNEWS when prompted to ensure you are fully opted into the promotion.

Once your account is successfully verified, make your first deposit. From there, you will need to make $25 worth of trades on the platform to activate the offer. The best part? You do not need to make a single, massive $25 trade; any sum of trades that equals a total of $25 will satisfy the requirement and unlock your $25 sign-up bonus.

I love this cumulative structure because it gives us the freedom to spread our risk across multiple games on today's MLB slate. For example, you could place a few smaller trades on the Detroit Tigers (61-64) with probable pitcher Keider Montero on the mound, and combine them with action on Braxton Ashcraft and the hometown Pittsburgh Pirates (61-66). As soon as your total trades reach that $25 threshold, your $25 Kalshi bonus will be available in your account.
