New users betting on Thursday Night Football can turn a $5 wager into $100 in bonus funds by using the Underdog promo code YAHOOBONUS. The offer delivers a 20X return on the initial bet, requiring just a minimum $10 deposit to qualify.
To claim the bonus, users must register an account through the Underdog platform, enter the promo code YAHOOBONUS, complete verification, and place a first entry of at least $5. Once those steps are met, the $100 bonus funds are credited instantly. These bonus funds cannot be withdrawn outright but are subject to a playthrough requirement before becoming eligible for cashout.
The promotion applies to new customers aged 18 or older, with age restrictions rising to 19 or 21 depending on state laws. It is available in 40 states plus Washington D.C., with eligibility verified within the app. Underdog Fantasy, the platform offering the deal, requires that players be physically located in states where it legally operates.
Underdog suggests using the promo code specifically for Thursday Night Football contests, where bettors can enter pick’em contests with NFL, NHL, or college basketball picks. The site offers player projections to assist bettors in formulating entries. For example, Jaxon Smith-Njigba of Seattle is projected to exceed 89.5 receiving yards, with a “higher” pick recommended. Meanwhile, Denver’s Bo Nix and J.K. Dobbins are projected for 199.5 passing yards and 49.5 rushing yards respectively, with “lower” picks advised.
The promo code’s terms clarify that the bonus funds are issued regardless of whether the first bet wins or loses, making it a low-risk opportunity for newcomers to explore Underdog’s daily fantasy contests. All deposit methods require a minimum of $10, and the bonus is only valid on the first eligible entry.
Underdog also includes responsible gaming resources in its promotion. Players concerned about gambling can contact national helplines such as 1-800-MY-RESET or visit www.ncpgambling.org. State-specific support is provided for Arizona and New York via dedicated phone numbers and text services.
The offer was confirmed as of October 15, 2026, and remains active for users meeting the age and state requirements. With the NFL season in full swing, the YAHOOBONUS promo code presents a fresh incentive for sports fans looking to engage with Thursday’s games in a more interactive way.
