For new Kalshi customers ready to dive into the July 31, 2026, MLB slate, the platform offers a dynamic sign-up bonus structure. Whether you want to forecast Brandon Young’s performance against the Philadelphia Phillies, or you are looking to trade on Bryce Elder and the Atlanta Braves against the Washington Nationals, this promotion helps maximize your initial bankroll.

To qualify for the offer, new users must make a first-time deposit of at least $1. The bonus will be unlocked after the user has made $25 in total trades on the prediction markets. You can reach that trading threshold by predicting the outcome of tonight’s clash between the Miami Marlins and New York Mets, who are expected to start Freddy Peralta.

Once the $25 trading requirement is met, eligible users will receive between $15 and $500 in bonus trading credits. The distribution for this tiered bonus is as follows:

• 70% of participants receive $15 in bonus trading credits
• 24% of participants receive $35 in bonus trading credits
• 5% of participants receive $75 in bonus trading credits
• 0.65% of participants receive $100 in bonus trading credits
• 0.35% of participants receive $500 in bonus trading credits

Please note that these trading credits expire in 30 days and cannot be withdrawn. Kalshi is available in all 50 states, and users must be at least 18 years old to participate.

Matchup	Moneyline	Probability
PHI @ BAL	BAL -125 / PHI +106	BAL 53.4% / PHI 46.6%
WSH @ ATL	ATL -122 / WSH +102	ATL 52.6% / WSH 47.4%
MIA @ NYM	NYM -130 / MIA +109	NYM 54.2% / MIA 45.8%

Despite their underdog status on the moneyline, the Marlins actually boast a stronger statistical profile than the Mets heading into their matchup, presenting a compelling prediction opportunity. Miami’s offense has produced 464 RBIs and a .733 OPS, outpacing New York’s 431 RBIs and .687 OPS. Furthermore, the Marlins hold a slight edge with a 4.081 team ERA compared to the Mets’ 4.106 ERA.

Meanwhile, the clash between the Orioles and Phillies projects as a remarkably tight affair. Baltimore enters as the slight favorite, backed by an offense that has generated 483 RBIs and a .715 OPS, alongside a 4.206 team ERA. Philadelphia trails just slightly in those key categories, posting 457 RBIs, a .703 OPS, and a 4.264 ERA, setting the stage for a highly competitive prediction market.

How to Activate the Kalshi Promo Code BROAD15

Unlocking your sign-up bonus is a quick and structured process. To get started and claim your offer ahead of tonight’s scheduled MLB action in the Eastern time zone (ET), simply follow these steps:

1. Download the App: Navigate to your device’s app store and download the Kalshi app.
2. Register Your Account: Create a new account by providing standard personal information. You will also need to submit proof of identification to verify your account.
3. Use the Promo Code: During the registration process, ensure you enter the Kalshi promo code BROAD15 to attach the welcome offer to your new account.
4. Make a Deposit: Fund your account with a first-time deposit of at least $1.
5. Start Trading: To activate the offer and unlock your trading credits, you must make $25 worth of trades on the platform.

Keep in mind that you do not have to make a single trade worth $25 all at once. The requirement is simply a cumulative sum of $25 in trades. You can mix and match smaller predictions across the July 31 slate to reach that threshold. For example, you could trade a few dollars on whether Foster Griffin and the Washington Nationals will upset the Braves, and allocate the rest toward predicting the performance of Janson Junk and the Miami Marlins against the Mets. Once your total traded volume reaches $25, your bonus trading credits will become available.
