Fanatics Sportsbook is offering a new-user promotion tied to Oklahoma City vs. Dallas on Oct. 28, giving bettors a chance to earn $350 in FanCash with promo code SIBONUS350.
The offer is built as a seven-day bonus structure. Qualifying bettors can receive $50 in FanCash daily until the full $350 total is delivered, which gives the promotion a clear week-long payout window rather than a one-time reward.
How the offer works
The promo is framed as a welcome offer for bettors who want to back either Oklahoma City or Dallas in the matchup. The key requirement is using SIBONUS350, and the stated bonus amount is $350 in FanCash.
For new bettors, the appeal is simple: a single NBA game becomes the entry point to a larger promotional payout. Instead of a traditional one-night bonus, the FanCash is credited across seven consecutive days, with $50 arriving each day until the total reaches $350.
Why it matters
Promotions like this are designed to introduce new users to Fanatics Sportsbook while tying the welcome offer to a specific event. In this case, the event is Oklahoma City vs. Dallas on Oct. 28, which gives the bonus a clear deadline and a defined game context.
For anyone considering the offer, the important details are straightforward: it is for new bettors, it uses promo code SIBONUS350, and the bonus is delivered in FanCash over seven consecutive days.
That structure makes the offer easy to track and easy to value. The headline number is $350, but the daily pace of $50 in FanCash is what determines how the promotion is paid out.
