How the Underdog Promo Code Delivers a $1,000 Match for NFL Week 1
The Underdog promo code unlocks a 50% first-deposit match, and a code is required to activate it. New users simply enter COVERS during sign-up to secure the bonus before making a qualifying deposit ahead of Wednesday's Patriots-Seahawks opener.
- Minimum deposit of $10 required to qualify
- Match capped at $1,000, requiring a $2,000 deposit for the maximum bonus
- Bonus entries can take up to 72 hours to appear after the deposit resolves
- Playthrough of 1x the deposit plus bonus must be completed within 14 days
- Unused bonus balance is forfeited if the playthrough isn't met in time
For example, a $100 deposit on Patriots-Seahawks entries triggers a $50 match, creating a $150 balance that must be played through within the 14-day window. If those entries hit, winnings become eligible for withdrawal even before the full playthrough is finished. If the entries miss, the deposited funds are gone, but the promotional balance remains active toward future NFL Week 1 games as long as the 14-day clock hasn't expired. Traders comparing options can review the best prediction market promos before committing to a deposit amount.
