SI Sportsbook tends to focus on major US sports leagues like NFL, NBA, MLB, and NHL, offering deep markets and prop bets. Fanatics Sportsbook also covers these leagues but often features unique markets tied to fan engagement, such as special event bets. Odds can vary between the two, which creates opportunities for bettors to shop for the best lines.

SI Sportsbook offers a clean and intuitive interface focusing on quick bet placement and detailed statistics. Fanatics Sportsbook emphasizes rich graphics and integration with fan loyalty programs. Both platforms support mobile betting, though Fanatics may appeal more to casual bettors due to its fan engagement features.

Fanatics Sportsbook is known for aggressive promotional offers including sign-up bonuses, risk-free bets, and merchandise giveaways linked to betting activity. SI Sportsbook offers competitive bonuses but often emphasizes ongoing loyalty programs and sportsbook credits. Promotions can impact bettor profitability but require careful evaluation to avoid chasing bonuses at unfavorable odds. Arbitrage betting sidesteps this risk by focusing on guaranteed profit scenarios rather than promotional incentives.
