The Kalshi promo code ACTION gives new users up to $500 in bonus funds after a first $25 trade, and it's live for Tuesday's MLB card. My lean before the 7:05 p.m. ET first pitch on TBS is the Yankees moneyline at around $0.56 in Mariners vs. Yankees, since New York is the MLB home favorite with a pitching matchup I like. Sign up, trade $25, and the bonus climbs toward the $500 ceiling as you go.
Kalshi is a federally regulated exchange overseen by the CFTC, where contracts trade between a penny and 99 cents and settle at a flat dollar when they hit. It is not sports betting. Price equals implied probability, so a $0.56 Yankees contract is simply the prediction market giving New York about a 56% chance to win tonight.

Kalshi Promo Code ACTION: Trade on Mariners vs. Yankees Prediction
I'm on the Yankees, and the pitching matchup is why. New York hands the ball to lefty Ryan Weathers (3.79 ERA), and Seattle's lineup has been noticeably softer against left-handed pitching this year, so that's a favorable spot for the home side. The Mariners counter with righty Bryan Woo (4.31 ERA), a solid arm, but the edge tilts New York's way.
| Kalshi Market | Contract | Approx. Price | Implied Odds |
|---|---|---|---|
| Moneyline | Yankees to win | ~$0.56 | −126 |
| Moneyline | Mariners to win | ~$0.46 | +118 |
The other thing pushing me here is the bullpens. Both of these are among the best relief units in the game, so I expect a low-scoring, close night decided in the late innings, and that's exactly the kind of game I want the home favorite with the deeper pen. Pull up the live MLB odds and confirm the starters before you trade, since the price moves right up to first pitch.
