The Fanatics Sportsbook promo code SIBONUS is available as of July 30, and new users can claim up to $1,000 in FanCash across their first 10 days. Start with Thursday's MLB and WNBA slate, including Mariners-Dodgers and Liberty-Aces, to kick off your welcome offer.

How the Fanatics Sportsbook promo code works for MLB & WNBA betting

The Fanatics Sportsbook promo is structured as a 10-day match offer, giving new users up to $100 in FanCash each day for their first 10 days on the platform. Thursday's MLB and WNBA card is the perfect starting point, with marquee matchups like Mariners-Dodgers and the Liberty visiting the Aces in Las Vegas giving you plenty of markets to choose from on day one.

Here is how the offer works in practice. Place a wager of at least $1 on any market with odds of -500 or longer. If your bet wins, you keep the winnings as normal. If your bet loses, say you back the Mariners against the Dodgers and Seattle falls short, you receive your stake back in FanCash, up to $100 for that day.

The key terms and conditions to keep in mind are listed below:

  • Only available to new Fanatics Sportsbook users who do not already have an account.
  • Use promo code SIBONUS at 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.
  • FanCash is awarded on losing bets only, up to $100 per day.
  • FanCash bonuses are non-withdrawable and expire after seven days.
  • A 1x playthrough requirement must be completed before requesting a withdrawal.
  • The offer is 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.
  • This offer expires on Aug. 23, 2026.

The cumulative value of the welcome offer reaches up to $1,000 in FanCash when you repeat the process each day for 10 consecutive days. Thursday's slate, headlined by Mariners-Dodgers late and the Liberty-Aces showdown in Las Vegas, gives you a strong opening day to get started. This Fanatics Sportsbook new-user promo is one of the more flexible structures available among current sportsbook promos, since you are not locked into a single large wager to unlock the full value.
