SI Sportsbook Review & Ratings 2025: Is SI Sportsbook Legit?

We loved our first few hours at SI Sportsbook. This is because we were given $50 in free bet bonus tokens, just for making a $10 sports bet. It’s a great deal that competes well against some of the best online sports betting sites in the US and it’s available to all new Colorado-based customers at the SI Sportsbook. Basically, it gives you lots of extra wagering money to play with.

Like all bonuses, this deal comes with some important bits of small print. The main thing to remember is that your first sports bet has to be at least $10, and it needs to be made on odds of -200 or more. Plus, once you get your bonus credit, you only get 7 days in which to use it.

This offer compares favorably with some of the biggest US operators and puts SI Sportsbook on a par with our BetAmerica rating. There are certainly larger sports betting bonuses out there, but we felt that this deal offered us a great start at this awesome sportsbook!

On the surface, the SI Sportsbook looks and acts like any other sports betting site. This means that you get a familiar grid of betting odds along with tabs for things like promotions, customer support, and so on. All of which is held in a nice-looking website featuring bold reds, blacks, and whites.

But it’s when you delve a little deeper that you realize just how good SI Sportsbook is. This is because there are lots of cool little things like the BetFeed that lets you see what other punters on the sportsbook are betting on. Plus there’s also a great “Recommended” section that gives you expert help in identifying some of the best value bets on the biggest sporting events.

We should note that SI Sportsbook is also a very mobile-friendly operator. Not only is the basic sports betting website easy to use from a mobile device, but there are also some excellent SI Sportsbook apps that are available for all modern iOS and Android devices.

We found that SI Sportsbook features all of the main deposit methods that you get in all of the best online gambling sites. This means that you can add money to your account with debit and credit card brands like Visa, MasterCard, and Discover or try alternative payment methods like PayNearMe, Play+, ACH, or even a regular online bank transfer. In addition, our tests for the SI Sportsbook review revealed that we could deposit from $10 at a time, and the money showed up in our account in just a couple of minutes.

Making withdrawals also turned out to be pretty easy. While you could only make withdrawals either as an ACH bank transfer or via Play+, we found that all withdrawals were processed efficiently and that we weren’t hit with any processing fees. All of which should give you a stress-free way to get your well-deserved winnings.

SI Sportsbook is clearly a betting site that likes to take good care of its customers. We found that it was easy to get help with verifying an account, and the customer care agent we communicated with was professional.

Getting in touch was pretty easy as we just had to send an email via the contact form in the help center. This proved to be very simple, and we were also given a chance to include a screenshot. It was a bit disappointing to find nothing in the way of a live chat or telephone hotline, but this is not unusual for US operations and we found a similar scenario when we completed our Barstool review, amongst others.

SI Sportsbook does have an excellent FAQ section. Plus, there are handy articles that give you clear information about making deposits and withdrawals. All in all, a good site for customer support.

At the time of writing this review, SI Sportsbook was regulated by the Colorado Limited Gaming Control Commission. This meant that the sportsbook was only licensed to operate within Colorado, but it looks like SI Sportsbook is planning to open up in other states in the coming months. The fact that SI Sportsbook has bothered to get full licensing and regulation shows that it can be trusted and is a legit betting site.

Each time an operator launches in a different US state, we ask question whether it’s operating legitimately. Even though Borgata is one of the biggest, for every state that it operates in we’ll still ask ‘Is Borgata legit?’ each and every time.

Elsewhere we found plenty more trust features on the SI Sportsbook site. This could be seen in the way that the brand looks after your data, thanks to its encryption technologies. Plus, we liked that the Patron Protection section gives you lots of ways to keep your sports betting in check.

You may not find any of those standard reward programs at SI Sportsbook, but this site has lots of cool deals that all registered customers can get. Some of these are fairly basic deals that simply give you enhanced odds on some big sporting events. However, some of the special offers are a little more complex, like the one that gives you the chance to win up to $10,000 by correctly predicting 10 NFL game results.

SI Sportsbook is also a betting site that rewards you for taking a risk with your bets. For example, there’s a parlay betting deal that could give you lots of bonus bet tokens just for putting down a three-leg parlay on the weekend. Plus, with enhanced wincasts and special bets, it shows that SI Sportsbook is a betting site like no other.
