Kalshi’s $15 Welcome Bonus Gets You Started
New customers get a fast $15 sign-up bonus that you can deploy right on today’s MLB slate. I always tell readers to grab these intro offers—they’re the smartest way to test new strategies without touching your own cash.
Whether you want to predict the AL East clash between the 49-51 Baltimore Orioles and 50-48 Boston Red Sox at Fenway, or prefer the 42-58 New York Mets visiting the 62-37 Milwaukee Brewers, this offer works as an excellent launchpad.
Here’s the play: Kalshi’s prediction markets are legally available in all 50 states if you’re at least 18. New users register here and make a first deposit of at least $1.
The $15 bonus unlocks automatically after you make $10 total in trades. You don’t have to risk it all on one wild trade either. Once your qualifying trades settle—however you break up that $10—the bonus funds are fully unlocked and ready to use.

Today’s MLB Prediction Market Odds
| Matchup | Probability |
|---|---|
| PIT @ NYY | PIT 48.3% / NYY 51.7% |
| BAL @ BOS | BAL 43.0% / BOS 57.0% |
| LAD @ PHI | LAD 44.5% / PHI 55.5% |

Let’s talk strategy. If you use your unlocked Kalshi funds to back today’s heaviest favorite, the Milwaukee Brewers, a $10 trade returns a safe but modest $4.63 in profit. But if you’re hunting value and take a shot on the biggest underdog, the New York Mets, that same $10 stake nets a sweet $17.70 in winnings.
When I’m searching for an edge, I’m targeting the Los Angeles Dodgers (+116) as a live underdog against Philadelphia. The stats paint a clear picture: Los Angeles boasts a superior offense, hitting .260 as a team compared to Philadelphia’s .236 team average.
Add in the Dodgers’ pitching advantage with a sharp 3.49 collective ERA—comfortably besting the Phillies’ 4.21 team mark—and we’ve got a real chance at a profitable upset.
