How to Use the Underdog Promo Code for $1,000 in Bonuses

New users can activate the Underdog promo code COVERS to secure a 50% deposit match worth up to $1,000. A minimum deposit of $10 is required, and the maximum bonus is unlocked with a $2,000 deposit. This offer applies to eligible Prediction Picks and Combo entries, including those tied to Thursday's Lions vs. Bills matchup.

Here are the key terms to know before signing up:

  • Minimum deposit of $10 required to qualify
  • Bonus match capped at $1,000 on a $2,000 deposit
  • Promotional funds can take up to 72 hours to post after the deposit resolves
  • Users must complete 1x the deposit plus bonus in entry fees within 14 days
  • Unused bonus funds are forfeited if the playthrough isn't completed in time

Consider a $100 deposit, which triggers a $50 match for a $150 combined balance. If a Prediction Pick built around the Lions vs. Bills matchup hits, the payout adds to the balance while progress continues toward the 14-day playthrough requirement. If the pick misses, the deposited funds are still in play toward completing that requirement, since the 1x turnover applies to entry fees placed rather than results alone.

Bettors can also compare this offer against other bookmakers through a list of best prediction market promos to see how it stacks up.
