Fanatics Sportsbook is dangling a new-bettor offer tied to Oklahoma City vs. Dallas on Oct. 28, and the pitch is simple: use promo code SIBONUS350 and you can unlock $350 in FanCash if you meet the qualifying requirements. The bonus is spread across seven consecutive days, giving eligible customers $50 in FanCash each day until the full amount is reached.
The timing is what makes the offer stand out. The matchup is already drawing interest because it puts the Thunder's unbeaten start in the spotlight against the Mavericks' home court advantage, and Fanatics Sportsbook is using that attention to court first-time customers. For anyone searching the deal now, the key detail is that the offer is available only to new customers and availability varies by state, with terms applying to the bonus and to FanCash itself.
The mechanics matter. A bettor who places a $20 wager on Oklahoma City to cover the spread at -110 odds on Oct. 28 would return $38.18 in profit if the Thunder win and cover. But the offer does not depend on that first wager cashing to start the bonus sequence. If the bet misses, the bettor still receives the first $50 in FanCash the next day, which is why the promotion reads less like a single-game flyer and more like a one-week welcome package.
That structure also leaves one practical gap: the full qualifying steps are not spelled out here, only that the bettor must satisfy the requirements to unlock the full $350. What is clear is that the promotion is built for new sign-ups around one game, one date and one week of rewards, and that the value arrives even if the first ticket loses. For bettors weighing Oklahoma City vs. Dallas, that is the part of the pitch that changes the calculation today.
