Use the Fanatics Sportsbook promo code SIBONUS to claim up to $1,000 in FanCash as a new user. Place your first wager on McGregor vs. Holloway at UFC 329 and get up to $100 in FanCash back if it loses. This Fanatics Sportsbook new-user promo is available through July 11.

How the Fanatics Sportsbook promo code works for UFC 329

The Fanatics Sportsbook promo gives new users up to $100 in FanCash on their first day, making McGregor vs. Holloway the perfect fight to kick things off. All you need to do is place a wager of at least $1 on any market at odds of -500 or longer, and if that bet loses, Fanatics returns your stake as FanCash. You can repeat this process each day for your first 10 days, building toward a total welcome package of up to $1,000 in FanCash.

Say you back Conor McGregor to win at UFC 329 and the bet loses, Fanatics sends your stake back as FanCash, up to $100. If your bet wins, you keep the winnings as normal and still have nine more days to take advantage of this Fanatics Sportsbook sign-up bonus. Either way, day one on the platform gives you a strong start heading into fight night.

Here are the key terms to keep in mind before claiming this offer:

  • Available to new Fanatics Sportsbook users only who do not already have an account.
  • 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 at odds of -500 or longer.

  • The overall offer expires Aug. 23, 2026.
  • Available 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.
