Trade $25, Get Up to $500 on MLB Tonight
This is Kalshi's newest offer, and it dwarfs anything that came before it. Where earlier promos capped out small, this one goes all the way up to $500 in bonus value on a single $25 trade — which is exactly why fans are already calling it the best MLB prediction market promo of the summer.
Point that bonus at the Monday MLB odds. Dodgers vs. Phillies starts at 7 p.m. ET on ESPN, followed by Cardinals vs. Angels at 10 p.m. ET on ESPN. Both games give new traders a perfect stage to test prediction markets.
Dodgers vs. Phillies and Cardinals vs. Angels
Dodgers vs. Phillies pits two of the National League's biggest names against each other in prime time. Expect sharp movement in the MLB odds as first pitch approaches.
Later, Cardinals vs. Angels closes out the ESPN doubleheader. Track prices on each game with the two live widgets above, then trade your position with the Kalshi referral code ACTION bonus.
Why Trade MLB on Kalshi
Kalshi runs regulated prediction markets, so you trade contracts on real outcomes rather than placing traditional bets. Prices move with the market, which means you can enter or exit a position whenever you like.
That flexibility, paired with a brand-new Kalshi promo code ACTION offer worth up to $500, makes this the best MLB prediction market promo for fans this summer. You control every trade, and the new bonus lowers your cost of entry.
