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

NFL Week 1 arrives with a loaded schedule, and new bettors can capitalize on the action with a Fanatics Sportsbook promo code. The season kicks off with the Patriots-Seahawks Super Bowl rematch on Wednesday, followed by the 49ers-Rams international showcase in Melbourne on Thursday, and a full slate of division rivalries through Monday night. Claim up to $1,000 in FanCash as of Sept. 7 to start your Week 1 betting journey.

How the Fanatics Sportsbook new-user promo works for Week 1

The Fanatics Sportsbook promo gives new users a chance to earn bonus funds across their first 10 days on the platform. You'll place a wager of at least $1 on any sports market with odds of minus-500 or longer. If your bet loses, Fanatics returns your stake as FanCash, up to $100 per day. You can repeat this process for 10 consecutive days, building toward the full $1,000 bonus.

Here's how it plays out during Week 1. Say you place a $50 bet on the Patriots-Seahawks matchup at minus-500 odds and lose. Fanatics credits you $50 in FanCash, which you can use on Thursday's 49ers-Rams game in Melbourne or any other Week 1 matchup. If you win that initial bet, you keep your winnings and can still place another qualifying wager the next day. The bonus resets daily, allowing you to maximize your FanCash across the entire opening week of the season.

The sportsbook promos landscape is competitive, but this offer stands out for its flexibility and daily reset structure. Here are the key terms:
