How the Fanatics Sportsbook promo code works for NFL Week 9
The Fanatics Sportsbook promo delivers $350 in total FanCash across seven consecutive days. You'll earn $50 each day for a week after placing a qualifying $20 bet at odds of -500 or longer. This structure means you can start with Thursday's Ravens-Jaguars game and continue through the week's marquee matchups, including Monday's Buffalo-Minnesota showdown between two undefeated division leaders.
Here are the key terms and conditions for this offer:
- New users only; existing account holders cannot claim this bonus.
- Deposit a minimum of $10 to activate the welcome offer.
- Place a $20+ wager at -500 odds or longer within seven days of registration.
- Earn $50 in FanCash daily for seven days by placing qualifying bets each day.
- Each day's $50 reward expires 24 hours after it's issued, so use it promptly.

- Available in AZ, CO, CT, DC, IA, IL, IN, KS, KY, LA, MA, MD, MI, MO, NC, NJ, OH, PA, TN, VA, VT, WV, and WY (not available in New York).
Let's say you bet $20 on the Ravens to cover against Jacksonville on Thursday and win. You'll immediately unlock your first $50 in FanCash, which you can use on Friday's Cincinnati-Atlanta game in Madrid or any other Week 9 matchup. If your Thursday bet doesn't hit, you still earn the $50 FanCash reward for placing the qualifying wager, allowing you to continue building your bonus throughout the week. The key is placing a qualifying bet each day to unlock the daily $50 increment.
When exploring sportsbook promos, you'll find that this seven-day structure gives you multiple opportunities to use your bonus across the entire NFL Week 9 slate. From Thursday's Ravens-Jaguars opener through Monday's Bills-Vikings prime-time matchup, you have plenty of betting opportunities to maximize your FanCash rewards.
