How the Kalshi Welcome Offer Works
The Kalshi welcome offer is built for new customers who want to jump into prediction markets. You’ll need that promo code to lock in your eligibility for the sign-up bonus, which varies based on how much you participate.

Today’s MLB Markets and Betting Lines
Prediction markets let you trade on real-world events before they happen. For today’s MLB action, Kalshi gives you a straightforward way to engage with game outcomes. Here’s what the consensus market figures look like for this week’s top matchups, showing the implied probability based on current trading activity.
| Matchup | Implied Probability |
|---|---|
| SEA @ NYY | SEA 45% / NYY 55% |
| BOS @ TOR | BOS 53% / TOR 47% |
| KC @ LAD | KC 34% / LAD 66% |
The Yankees come into their matchup with a slight edge according to market consensus. The season-long numbers back this up, especially when you look at pitching and run prevention:
| Team | AVG | OBP | OPS | ERA | K/9 | WHIP |
|---|---|---|---|---|---|---|
| NYY | .230 | .310 | .720 | 3.28 | 9.08 | 1.17 |
| SEA | .228 | .307 | .681 | 3.79 | 8.65 | 1.20 |
New York shows advantages in both offensive production and pitching efficiency. They’ve got the better run prevention profile with a 3.28 ERA compared to Seattle’s 3.79 ERA.
