The Fanatics Sportsbook promo code SIBONUS is available now through July 11, giving new users a chance to earn up to $1,000 in FanCash across their first 10 days. Start with UFC 329 on day one and put up to $100 in FanCash on the line as McGregor and Holloway headline one of the biggest MMA cards of the summer.

How the Fanatics Sportsbook promo code works for UFC 329

The Fanatics Sportsbook promo is structured as a 10-day welcome offer, and UFC 329 is the perfect event to kick things off on day one. Each day, place a wager of at least $1 on any market at odds of -500 or longer, and if that bet loses, you get your stake back in FanCash, up to $100 per day. This is one of the more flexible sportsbook promos available right now, since it applies to any market rather than locking you into a specific bet type.

For UFC 329, that means you could wager $100 on Conor McGregor to win the main event. If McGregor pulls off the victory, you keep your winnings as normal. If Holloway gets the better of him, Fanatics returns your $100 stake as FanCash, giving you another shot the next day. The same logic applies whether you are betting the co-main event between Benoît Saint Denis and Paddy Pimblett or any other fight on the card.

Here is a quick look at the key terms for this Fanatics Sportsbook new-user promo:

  • Available to new users only 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.
  • Place a minimum $1 wager at odds of -500 or longer on any market.

  • FanCash carries a 1x playthrough requirement before withdrawal is available.
  • Bonus FanCash expires seven days after it is issued.
  • The overall welcome offer expires Aug. 23, 2026.

The Fanatics Sportsbook sign-up bonus rewards you across 10 consecutive days, meaning UFC 329 is just the starting point. Repeat the process each day for up to $1,000 in total FanCash over the full promotional window.
