1. Polymarket
Polymarket is one of the most popular MLB prediction market apps, and you'll see why once you start trading. But before you do, use the Polymarket promo codeACTION during registration to get a $20 bonus after your first deposit of $10+.
It's not a massive bonus, but we can still make some noise in MLB odds with a $30 starting point. The two left-handed starting pitchers could neutralize each team's best bat in the lineup, so a parlay of Ozzie Albies + William Contreras home runs would be a good way to start your Polymarket journey.
