best stats to use for sports betting header

Based on the size of the global sports betting market, it’s no surprise that there are tons of sites offering databases and trend analysis for sports betting. Some sites provide their raw data for free. Others charge for their databases and provide exclusive commentary and proprietary analytic tools.

By combing through past sporting events and familiarizing yourself with different trends, you can gain invaluable insight into predicting the future and become highly successful sports bettor.

What Is the Best Free Sports Stats Database?

FiveThirtyEight

Some of the sharpest statisticians in the industry work at FiveThirtyEight. Nate Silver (who has appeared on Time Magazine’s’ Top 100 Most Influential People in the World issue) started FiveThirtyEight to write on, analyze, and predict NBA games with an advanced form of statistical analysis by the name of sabermetrics. Nate Silver’s brainchild has applied world-class statistical methodology to predict the future of everything from federal elections to the winner of the Super Bowl.

Not only does FiveThirtyEight make all of their data publically available (thanks for their firm belief in transparency), but they offer a predictive model for both the NBA and the NFL. They employ two different systems: “ELO” and “CARMELO” rankings.

Nate Silver describes them as follows:

“Elo ratings are a measure of team strength based on head-to-head results, margin of victory and quality of opponent, while our CARMELO projections estimate a player’s future performance based on the trajectory of other, similar NBA players.”

Nate Silver created the CARM-Elo model with a combination of both the ELO ratings and CARMELO projections. As a forecast model, the CARM-Elo system projects results based on a team’s roster, as well as historical game results. The CARM-Elo model is predicated on over 50,000 simulations of the remainder of the season, and it takes fatigue, home courts in higher altitudes, even distance traveled to games into account. Additionally, when it comes to predicting the playoffs, the CARM-Elo model also gives a small bonus to teams with significant playoff experience.

This is a great model and one that we recommend integrating into your sports bets. Correct more often than not,  it’s also free, simple, and efficient. Plus, few have ever found a way make data more aesthetically appealing and exciting than the fine folks at FiveThirtyEight.  

What Are the Best Subscription-Based Sports Stats Databases?

Killer Sports

Killer Sports is free (although you can purchase other people’s trends on the platform), and in our opinion, it’s one of the best available databases to sports bettors. In the past, the only people who had access to the same extensive data either worked at conglomerates like ESPN or paid thousands of dollars for programs that had to be updated every day.

Now, Killer Sports offers its patented SDQL (Sports Data Query Language) to anyone who subscribes to their services. It is undoubtedly the most comprehensive database available to the public.

What makes Killer Sports SDQL database so revolutionary? It allows users a unique opportunity to build and save their own trends, access team comparison tables, and access statistics that no other database currently offers their subscribers. The possibilities of what you can with Killer Sports data are limitless.

With their weekly reports on new emerging trends in their SDQL database, it’s impossible not to see why Killer Sports is a favorite of “sharps” everywhere.

Sports Insights

Sports Insights is an excellent tool for bettors who want access to statistics and shifting odds in real time. What’s more, Sports Insight has a dedicated smartphone application for bettors. With a subscription, bettors can access live odds from over 50+ sportsbooks, including every betting site we review. As far as tools for line shopping assistance, it doesn’t get much better.

Sports Insights also offers access to information concerning real-time betting trends. They clearly show the number of bets, as well as the percentage of money placed on every game, allowing you to determine why sportsbooks may be shifting their odds. This is a massively valuable tool for any “sharp”.

The utility of the Sports Insights tool doesn’t stop there. It also offers features such as Value Meter, Line Predictor, Line Watcher, injuries, weather and matchups data, as well as proprietary analytic tools such as Locate Reverse Line Movement (RLM), which compares betting percentages to the movement of odds.

Sports Insights also hosts online “hangouts” where subscribers and professional analysts can discuss all things sports betting. These hangouts are held every weekend night at 6:30 PM EST, and it’s a great opportunity to interact and converse with sports betting peers.

Which Sports Stats Service Should I Choose?

If you’re just starting out, we advocate sticking with the free services. Once you start developing your identity as a sports bettor and get accustomed to the nuances of sports betting a subscription service will help you gain a valuable edge over your sportsbook.
