Polymarket Promo Code Offer: Claim $20 for Giants vs. Dodgers

The Polymarket promo code COVERS unlocks a Deposit $20, Get $20 Trading Bonus for new users on the platform's U.S. mobile app. Unlike traditional sportsbook promotions, Polymarket operates as a prediction market, meaning you are trading event contracts rather than placing standard wagers. To trigger the bonus, you must deposit a minimum of $20 after registering with the code.

Here is a breakdown of the key terms tied to this offer:

  • Eligibility: New users only who meet the legal age requirement in an authorized jurisdiction
  • Minimum deposit: $20 required to unlock the $20 trading bonus
  • Qualifying trade: A real-money trade must be placed before bonus funds are credited
  • Wagering requirements: A 1x playthrough on the bonus amount is typically required before withdrawal
  • Market restrictions: Certain markets or events may be excluded; review terms carefully
  • Expiry: Bonus funds generally expire within seven to 30 days of being credited
  • Mobile only: This offer is available exclusively through the Polymarket mobile app

With the Dodgers struggling offensively heading into Monday's game against the Giants, there is plenty of intrigue around this series opener. Roki Sasaki takes the mound for Los Angeles with a 5.97 ERA, while San Francisco counters with Trevor McDonald, who was brilliant in his season debut with seven innings of one-run ball. If you trade on the Dodgers to win and they come through, your bonus funds help extend your trading activity. If the Giants pull off the upset behind McDonald, you still have your trading bonus to deploy on the next market.
