For example, Fridays and weekends often come with reload bonuses or parlay boosts tied to major sports events. Mondays and Thursdays are popular for NFL-related promos, such as profit boosts or "No Sweat Bets" on prime-time games.

Holidays and major sporting milestones—like the Super Bowl, March Madness, or the NBA Finals—also bring out some of the most aggressive SI Sportsbook promotions, including enhanced deposit bonuses and exclusive bet offers.

Savvy bettors time their activity around these high-value promo windows. If you're looking to get the most out of SI Sportsbook promos, it pays to align your bets with these key days and events.

For parlays, SI Sportsbook frequently provides parlay insurance, which refunds your stake as a Bonus Bet if just one leg of a multi-leg parlay loses. There are also profit boosts available for parlays, increasing your payout percentage on successful multi-leg bets.

These targeted promos give users more reason to engage with dynamic betting formats while reducing some of the risk. If you enjoy fast-paced or multi-leg wagers, SI Sportsbook’s promo structure makes these options even more rewarding—both financially and in terms of betting experience.

17. Are There Any Risks With SI Sportsbook Promos?

While claiming sportsbook promos with SI Sportsbook can be a great way to maximize your betting profits, it's crucial to be aware of their potential risks.

Four of the most notable risks attached to promo offers are: 

• No Guaranteed Winnings: Whether it's a $150 Bonus Bet, a $1,000 risk Bonus Bet or a 50% deposit bonus, if you place your bonus credit on a losing bet you will still come away with no more cash than when you started.  
  
  
• Risk of Losing Money: One of the most common ways bettors lose money through promos is through No Sweat Bets. Let's say you're gifted a $500 risk Bonus Bet and you place your $500 on the losing side of a game, you won't be refunded with $500 of withdrawable cash, but instead $500 of site credit (often in the form of a Bonus Bet). Place this Bonus Bet on the losing side and you've just lost $500 to the sportsbook. 
  
  
• Limited Number of Sign-Up Bonuses: While sign-up bonuses can be generous, you can only ever receive one sign-up bonus from each sportsbook (when you first create an account). This means that there's only a set number of sign-up bonuses available to each user. As a result, relying purely on these may not be a sustainable long-term plan.
  
  
• Misuse of Promos: Certain promos have more complex rules and often hidden T&Cs. As a result, if you go into them without proper guidance and support you can risk reducing the amount of overall profit you earn, or worse, lose money.

But it isn't all doom and gloom. There is one way you can guarantee profits from sportsbook promos risk-free, every time.

18. How to Guarantee Profit From SI Sportsbook Promos

While it's true risks can arise when claiming sportsbook promos, one clever technique exists that can remove them and guarantee you profits from SI Sportsbook promos every time.

Promo conversion (A.K.A matched betting), is a fully legal, super simple (with the right platform) method of turning sportsbook promos into guaranteed cash.

Simply put, it involves betting on one side of a game to qualify for a sportsbook promo, then betting on the other side to cover both outcomes and remove the risk. Repeat this process using your new promo and voila! You've locked in a guaranteed profit.
