Wednesday, Aug. 12 brings a loaded slate of baseball and basketball action, making it the perfect day to claim up to $1,000 in FanCash with the Fanatics Sportsbook promo code. The MLB card features marquee matchups like Mariners-Yankees, Red Sox-Blue Jays, and Mets-Braves, while the WNBA adds two compelling games to round out the evening. New users can maximize their welcome offer by placing their first wager on any of these games.

How the Fanatics Sportsbook promo code SIBONUS works for MLB and WNBA betting

The Fanatics Sportsbook promo allows new users to claim up to $100 in FanCash for each of their first 10 days on the platform, totaling up to $1,000. Here's how it works: place a $1 wager on any market with odds of -500 or longer. If your bet loses, you'll receive your stake back as FanCash, up to $100 per day. You can repeat this process daily for 10 consecutive days, making it an excellent opportunity to explore the sportsbook while betting on the day's best games.

The offer applies to all sports and markets available on Fanatics Sportsbook, so you can use it on any of Wednesday's MLB games or WNBA matchups. For example, if you place a $50 wager on the Mariners-Yankees game and lose, you'll receive $50 in FanCash. Alternatively, if you bet $100 on the Mets-Braves game and your pick doesn't come through, you'll get $100 in FanCash back. The key is that your bets must have minimum odds of -500 to qualify for the bonus.
