Kalshi Promo Code BROAD (August 2026): Get Up to $500 Bonus for Phillies vs. Cardinals MLB Predictions
By Bob Wankel
Published:
By utilizing our exclusive Kalshi promo code BROAD, eligible users can receive up to a $500 sign-up bonus, which is unlocked after making just $25 in trades on the platform. This bonus can be applied to predictions on Wednesday MLB games, including the Phillies vs. Cardinals matchup this afternoon. It is important to note the distribution of the welcome bonus is highly skewed: an estimated 70% of new users receive a $15 bonus, approximately 24% receive a $35 bonus, about 5% receive a $75 bonus, and less than 1% receive the top $100 or $500 amounts. This welcome offer is not available to users in Michigan or Nevada.
Kalshi Sign-Up Offer Details
The Kalshi welcome offer is designed to immediately give new users value when they engage with the platform’s prediction markets. By using our exclusive promo code BROAD, new Kalshi customers can claim a sign-up bonus of up to $500.
To be eligible for the bonus, users must be new to Kalshi, at least 18 years of age, and located outside of Nevada or Michigan. A minimum first-time deposit of $1 is required to qualify for the funds. The bonus itself is unlocked once the user has made $25 in total trades across any prediction market—whether focused on MLB outcomes, political events, or economic indicators. This allows users to start making predictions on markets—such as whether the Phillies will win or if Zack Wheeler will record a specific number of strikeouts—and quickly unlock their potential bonus.

Use Kalshi MLB Promo Today: Phillies vs. Cardinals Moneylines
The Philadelphia Phillies enter Busch Stadium today as the clear favorite against the St. Louis Cardinals, a status reinforced by their superior overall season record. Based on calculated win probabilities, the Phillies carry a significant edge in the moneyline market for this matchup, making it an excellent opportunity to utilize your unlocked bonus funds.
Below are the implied full-game moneylines for Wednesday’s contest:
| Team | Moneyline | Win Probability |
|---|---|---|
| Philadelphia Phillies | -150 | 60% |
| St. Louis Cardinals | +167 | 40% |
These implied odds are calculated from consensus win probabilities and were last updated on August 12, 2026, at 09:12:20 UTC.
The Phillies, currently sitting at 64-56, are the stronger bet as the moneyline favorite (-150). A successful $10 wager on the Phillies would yield a profit of $6.67. Conversely, if the underdog Cardinals (59-60) manage the upset at home (+167), a $10 bet would return a $16.70 profit.
From a betting trends perspective, the Phillies have established themselves as one of the stronger teams in the league, giving them momentum as the road favorite. While the Cardinals are defending home turf, their near-.500 record suggests volatility, making them a high-risk, high-reward play as the underdog. The pitching matchup further solidifies the market lean toward the visitors, with Zack Wheeler taking the mound for Philadelphia against Kyle Leahy for St. Louis.
