Phillies vs. Dodgers: Trade the Playoff Rematch With a Polymarket Promo Code

The Polymarket promo code COVERS is the key to unlocking a $50 welcome bonus for new users in most U.S. states, excluding Nevada. To trigger the offer, you must deposit a minimum of $20 after registering your account. Unlike traditional sportsbook promotions, Polymarket operates as a prediction market platform, meaning you are trading on outcomes rather than placing standard bets. With the Dodgers riding a five-game winning streak and winners of 12 of their last 14 games, you might trade on Los Angeles to take the series. On the other hand, if you believe Zack Wheeler's 1.67 ERA and the Phillies' momentum off a three-game sweep in San Diego give Philadelphia the edge, you could trade accordingly. If your trade on the Phillies wins, your position pays out based on the market price. If it loses, you are out the amount you traded.

Terms and conditions apply to the bonus, including the requirement to provide a valid photo ID and selfie during registration, and the offer is only available to users physically located in an eligible state. For a full breakdown of available offers, check out the best prediction market promos compared in one place.
