Simply deposit $10 and Polymarket credits a $20 bonus to your new account.

Prediction markets price in real time. You buy a "Freddie Freeman home run" contract before he bats, then exit or hold as the at-bat plays out. Enter the Polymarket promo code ACTION at registration, fund with $10, and deploy $20 in bonus funds on Mariners vs. Dodgers props.

Why Polymarket Leads in Player Prop Markets
Prediction markets turn real-world events into contracts you trade, and Polymarket leads this category among all prediction market apps available for tonight's MLB slate.
The Polymarket promo code ACTION offers new users a low-cost entry point — $10 deposit for $20 in bonus funds — to unique player prop markets unavailable on traditional sports betting platforms. Home run odds shift in real time based on batter matchups, pitcher adjustments, and live game conditions. That dynamic pricing makes this one of the best prediction market promos for prop traders who want to react to inning-by-inning action and share opportunities with friends. Check the latest MLB odds alongside Polymarket contract prices before first pitch — when the two markets diverge on player props, that gap is where the trading edge lives.
Mariners vs. Dodgers Polymarket Prop Pick
Pick: Mookie Betts home run. Buy a Betts home run contract at current market price. Betts has been hot this season and faces a Mariners bullpen prone to giveaways. Deploy the Polymarket promo code ACTION bonus funds to position on Betts prop value, and consider sharing this code with friends who want in on late-night baseball trading. For users who want to compare fixed-odds alternatives alongside Polymarket, the MLB betting promos page covers the top sportsbook welcome offers available for tonight's slate as an alternative route in.
