How the Fanatics Sportsbook promo code works for Week 1 college football

The Fanatics Sportsbook promo gives new bettors a chance to earn bonus funds across your first 10 days on the platform. Here's how it works: place a wager of at least $1 on any sports market with odds of minus-500 or longer, and if your bet loses, you'll receive your stake back as FanCash, up to $100 per day. You can repeat this process for 10 consecutive days, building toward the full $1,000 bonus.

Let's say you place a $50 wager on LSU to cover the spread against Clemson on Saturday night. If the Tigers fall short, you'll get $50 in FanCash credited to your account. If you win that bet, you keep your winnings and can place another qualifying wager the next day. The bonus FanCash expires after seven days, so you'll want to use it before it disappears. This offer applies to all sportsbook promos available through Fanatics, making it an excellent way to explore the platform's full range of betting options.

Here are the key terms and conditions for this welcome offer:

• 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 bonus.
• A minimum deposit of $10 is required to qualify.
• Wager at least $1 on any market with minus-500 odds or longer.

• Bonus funds expire after seven days and cannot be withdrawn.
• The offer expires Aug. 23, 2026, so claim it before the deadline passes.
• You must complete a 1x playthrough requirement before requesting a withdrawal.
