Polymarket Promo Code Details for $20 Wednesday Bonus

The Polymarket promo code COVERS unlocks a deposit match bonus for new users looking to trade on Wednesday's action-packed schedule. The Magic lead the Pistons 1-0 in their NBA playoff series, while the Thunder hold a 1-0 advantage over the Suns. NHL playoff action features the Flyers up 2-0 on the Penguins, a tied 1-1 series between the Stars and Wild, and the Oilers leading the Ducks 1-0. MLB games include Reds vs. Rays, Brewers vs. Tigers, and Yankees vs. Red Sox.

New users must deposit $20 to receive the matching $20 trading bonus. Unlike traditional sportsbook promotions, this offer is specifically designed for mobile app users who signed up for early access. Desktop users clicking the registration link will join a waitlist for future access. The bonus funds can be used to trade on various markets including sports outcomes, with typical terms requiring:

  • Eligibility limited to new users meeting age requirements in authorized jurisdictions
  • Mandatory use of promo code COVERS during registration
  • Minimum $20 deposit to qualify for the bonus
  • Real-money trades required before bonus funds are credited
  • Potential wagering requirements on bonus amounts
  • Expiration timeframes typically ranging from seven to 30 days

For example, if you trade $10 on the Magic to win their series and they advance, you receive the full payout. If they lose, you only lose your $10 stake. Compare this offer with other best prediction market promos to find the right fit for your trading strategy.
