Use $15 Bonus for the Home Run Derby
New Kalshi customers have a real chance to build their bankroll with a $15 bonus ahead of tonight’s highly anticipated MLB Home Run Derby. To qualify for this introductory offer, eligible participants must be at least 18 years of age and physically located in one of the many states where Kalshi currently operates.
Here is the game plan: to unlock the $15 bonus, new users are required to make a first-time deposit of at least $1 and execute a total of $10 in trades on Kalshi’s prediction markets.
Whether we decide to trade on a slugger in the Home Run Derby or explore other available MLB events on the platform, meeting the $10 trading threshold will successfully release the bonus funds into your account. Keep in mind that this specific promotion is exclusively available to brand-new Kalshi customers.
Probabilities for Each Slugger on Monday Night
| Team / Player | Win Probability |
|---|---|
| Kyle Schwarber (Philadelphia Phillies) | 22% |
| Junior Caminero (Tampa Bay Rays) | 18% |
| Munetaka Murakami (Chicago White Sox) | 16% |
| Jac Caglianone (Kansas City Royals) | 13% |
| Jordan Walker (St. Louis Cardinals) | 12% |
| Ben Rice (New York Yankees) | 11% |
| Bryce Harper (Philadelphia Phillies) | 10% |
| Willson Contreras (Boston Red Sox) | 6% |
Because traditional moneyline odds don’t apply to Kalshi’s prediction markets, exact payout calculations look a little different. However, based on the probability models, Kyle Schwarber sits at the top of the morning line as the favorite. If we place a $10 trade on him, the payout will be lower than if we take a swing on an underdog like Willson Contreras. We’re looking at a much bigger pay day if we successfully key on a longshot.
When I am handicapping this event, I look closely at the unique format. This year, there is no timer and no “outs.” Hitters get 20 swings in Round 1, followed by 15 swings in both Round 2 and the Finals. Every swing counts toward a player’s allotment, homer or not—but if you homer on your last swing in any round, you keep going until you don’t.
There is no bracket for the first round. Instead, the top four home run totals advance to the semifinals, seeded by their first-round performance (No. 1 vs. No. 4, and No. 2 vs. No. 3). With tiebreakers relying on home run distance in Round 1 and three-swing swing-offs in later rounds, raw power is going to be the deciding factor.
