How the Underdog Promo Code Works for NFL Week 1
Claiming this Underdog promo code offer starts with entering COVERS during registration, since a code is required to unlock the 50% first-deposit match. New users need to deposit at least $10 to qualify, and the match caps at $1,000, meaning a $2,000 deposit is needed to unlock the full bonus amount. The bonus arrives as entries, not cash, and can take up to 72 hours to post after the deposit resolves.
- Minimum deposit: $10
- Maximum match: $1,000 (requires a $2,000 deposit)
- Playthrough: 1x the deposit plus bonus within 14 days
- Unused bonus balance is forfeited after the 14-day window
Here is how it could play out using tonight's 49ers-Rams opener as an example. A $100 deposit triggers a $50 match, creating a $150 qualifying balance that must be played through within 14 days.
If entries tied to the 49ers-Rams game and other Week 1 matchups win, those winnings can be withdrawn during the turnover period, but if the entries lose, the unqualified bonus portion is simply forfeited rather than pulled from the original deposit. Shoppers comparing options across the industry can also check out these best prediction market promos before deciding where to put their first deposit this week.
