As the biggest sluggers step up to the plate for the MLB Home Run Derby, you can use the Kalshi promo code TSN15 to help you capitalize on the action. Specifically, new customers get a $15 bonus that is unlocked after signing up here and making just $10 in trades on the platform.
There is nothing better than a nice pay day, and this introductory offer provides the perfect opportunity to dive into today's Home Run Derby, as well as the All-Star Game. I'm using this exact strategy to build my bankroll, and with a little bit of smart handicapping, you can too.

Getting your hands on this offer is a fantastic way for new customers to grab a $15 sign-up bonus while taking a swing at the Home Run Derby prediction markets. Because Kalshi operates as a prediction market rather than a traditional sportsbook, it is widely available in most states across the country. Just note that users must be at least 18 to play.
To claim your $15 bonus, you simply need to make a first-time deposit of at least $1. Once your account is funded, the bonus will be unlocked immediately after you execute $10 in trades on their prediction markets. I love how accessible this makes the platform for folks wanting to test the waters on event contracts without risking a massive initial investment.
Probabilities for the Derby on Monday Night
For this year's Home Run Derby, the field is absolutely stacked. Below are the current win probabilities for each participant.
Player | Win Probability |
|---|---|
Kyle Schwarber | 22% |
Junior Caminero | 18% |
Munetaka Murakami | 16% |
Jac Caglianone | 13% |
Jordan Walker | 12% |
Ben Rice | 11% |
Bryce Harper | 10% |
Willson Contreras | 6% |
On a trading platform like Kalshi, event contract prices track closely with these win probabilities. If we're looking to back the favorite, placing a $10 trade on Kyle Schwarber at roughly 22¢ per share buys you about 45 contracts. A Schwarber victory nets a $45 total payout (a $35 profit).
If you want to chase a bigger payout with a longshot, placing a $10 trade on Willson Contreras at around 6¢ per share secures roughly 166 contracts. If he pulls off the upset, that yields a massive $166 payout (a $156 profit). I'm personally placing a few strategic trades across the board to maximize my chances of a winning ticket.
Since we are handicapping a unique exhibition rather than a standard game, our "betting trends" rely entirely on understanding the event's format. This year, there is no timer and there are no "outs." Every single swing counts toward a player's allotment: 20 swings in Round 1, followed by 15 swings in both Round 2 and the Finals. If a batter hits a home run on their final swing of any round, they keep going until they fail to homer.
There is no bonus round and no first-round bracket. Instead, the top four home run totals advance to the semifinals, where they are seeded 1-4 based on first-round performance (No. 1 vs. No. 4, and No. 2 vs. No. 3). If there's a tie, Round 1 is decided by Home Run Distance, while Rounds 2 and 3 feature three-swing swing-offs.
