Fanatics Sportsbook rolls out sign-up offer for Dolphins-Bills Thursday Night matchup
Promotion offers $100 in FanCash after a $10 wager and up to $100 back in FanCash on gamedays as Miami visits Buffalo in Week 3
Fanatics Sportsbook is offering new customers a promotional bonus tied to Thursday Night Football’s AFC East matchup between the Miami Dolphins and the Buffalo Bills, with a “bet $10, get $100 in FanCash” incentive and an opportunity to receive up to $100 back in FanCash on NFL gamedays through the 2025 season.
The Week 3 game kicks off at 8:15 p.m. and pits a 0-2 Dolphins team — which lost to the New England Patriots 33-27 at home after a poor season-opening loss in Indianapolis — against a 2-0 Bills squad that has scored a combined 71 points and is being installed as a heavy favorite. Fanatics listed Buffalo as a 13-point home favorite; other lines cited by the sportsbook and media have been in the -12.5 range.
Under the promotion, new users who sign up and place a qualifying $10 wager within seven days of account registration will receive $100 in FanCash, the site’s bonus currency that can be used to place bets and produce real-money payouts if those wagers win. Separately, users can earn FanCash refunds of up to $100 per NFL gameday by placing a losing American football cash wager of $1 or more at odds of +300 or longer; the refund equals the amount of the losing wager and requires an opt-in and that the wager settle as a loss. Full Fanatics terms apply.
The offer is available to new customers who register in Arizona, Colorado, Connecticut, Washington, D.C., Iowa, Illinois, Indiana, Kansas, Kentucky, Louisiana, Massachusetts, Maryland, Michigan, North Carolina, New Jersey, Ohio, Pennsylvania, Tennessee, Vermont, Virginia, West Virginia and Wyoming. New users in New York are instead being offered a no-sweat first bet with a maximum refund of $25, and the promo code POSTNY is provided for New York sign-ups.
Fanatics’ sign-up instructions mirror standard sportsbook onboarding: select the advertised bonus, choose the state of residence, fill out login and personal details, enter the promo code where required and make a deposit. According to the promotion copy, customers must register by Sept. 30, 2025, and any FanCash rewards will expire on Oct. 31, 2025.
The offer includes additional fine-print conditions. To qualify for the daily FanCash refund, bettors must opt in and place a qualifying wager each gameday; the qualifying wager must meet the stated odds requirement and settle as a loss. To trigger the initial $100 FanCash award, customers must place at least one cash wager of $10 or more at odds of -500 or longer within the seven-day window after signing up. Other wagering limits, state restrictions and platform-specific terms apply.
From a sporting perspective, Buffalo enters the matchup with quarterback Josh Allen, whose career record against Miami stands at 12-2. The Bills have opened the season with consecutive victories and high-scoring output, while Dolphins coach Mike McDaniel’s team has drawn scrutiny after two losses and early-season offensive struggles.
The promotion arrives as sportsbooks and operators ramp up marketing around marquee NFL matchups. Consumers are advised to read full terms and state-specific rules on the Fanatics Sportsbook app before registering and wagering, as eligibility and conditions vary by jurisdiction.
