What the Markets Are Saying
The prediction markets are giving the **National League** a slight edge heading into the Midsummer Classic:
| Team | Win Probability |
|---|---|
| National League All Stars | 55.4% |
| American League All Stars | 44.6% |
Here’s how the math works on Kalshi. If you trade $10 on the NL at roughly 55.4 cents per share, you’re buying about 18.05 shares. An NL victory pays out $18.05 total – that’s an $8.05 profit.
Flip it around and trade $10 on the AL at 44.6 cents per share. That gets you around 22.42 shares, which would pay $22.42 if the American League pulls the upset – a $12.42 profit.
The game winner isn’t your only option either. These platforms typically offer MVP markets, so you could back **Kyle Schwarber**, **Juan Soto**, or another star to take home the hardware.
With this many bonuses available, you’ve got plenty of opportunities to find an edge on the All-Star Game without risking much of your own bankroll.
