NFL Week 1 kicks off with some of the most compelling matchups of the season, and there's no better time to join Fanatics Sportsbook than Thursday, Sept. 10. New users can claim up to $1,000 in FanCash using the Fanatics Sportsbook promo code SIBONUS. Whether you're backing Seattle's momentum, San Francisco's star power, or any of the week's marquee matchups, this welcome offer gives you multiple opportunities to build your bankroll.

New customers only. Offer availability varies by state. Terms, including FanCash terms apply-see Fanatics Sportsbook app.

How the Fanatics Sportsbook promo code works for NFL Week 1

The Fanatics Sportsbook promo allows new bettors to earn up to $100 in FanCash per day for 10 consecutive days, totaling up to $1,000. Here's how it works: place a wager of at least $1 on any sports market with odds of -500 or longer, and if that bet loses, Fanatics returns your stake as FanCash. You can repeat this process daily throughout your first 10 days on the platform, making it an excellent way to explore different betting opportunities across NFL Week 1's slate.

The beauty of this offer is its flexibility. On Thursday night, you could back the 49ers against the Rams in Melbourne. If that wager doesn't land, you'll receive your stake back as FanCash to use on Sunday's games between Buffalo and Houston or Chicago and Carolina. If you win your initial Thursday wager, you keep your profits and can still claim the bonus on Friday or any of the following nine days. The sportsbook promos landscape is competitive, but this offer stands out for its extended window and daily reset structure.

Here are the key terms and conditions you should know:

  • Available only to new Fanatics Sportsbook users in AZ, CO, CT, DC, IA, IL, IN, KS, KY, LA, MA, MD, MI, MO, NC, NJ, NY, OH, PA, TN, VA, VT, WV, WI, and WY.
  • Use promo code SIBONUS during registration to activate the offer.
  • A minimum deposit of $10 is required to qualify.
  • Wager at least $1 on any market with minimum -500 odds.
  • Losing wagers return as FanCash, up to $100 per day for 10 days.
  • FanCash bonuses expire after seven days, so use them promptly.
  • The offer expires on Aug. 23, 2026.
  • Complete a 1x playthrough requirement before withdrawing funds.

This Fanatics Sportsbook new-user promo is particularly valuable during Week 1 because the NFL schedule provides multiple betting opportunities across several days. You're not locked into a single game or outcome; instead, you have flexibility to explore different bet types and matchups as the week unfolds.
