Walk into any sportsbook app and you'll see hundreds of betting options. Spreads, moneylines, totals, props — the choices are overwhelming. How do you know which bets are actually worth taking?
That's exactly why we built the A-F grading system in Edge. Every single bet available across major sportsbooks gets a letter grade that instantly tells you how much value it offers. No more guessing. No more gut feelings. Just clear, data-driven grades.
Edge's AI analyzes every available bet by comparing the offered odds against a calculated fair value. Fair value represents what the odds "should" be based on sharp market consensus, historical data, and our proprietary models.
The grade is determined by the gap between the offered odds and fair value:
The accuracy of any grading system depends on how well it estimates fair value. Edge uses multiple inputs:
Not all sportsbooks are created equal. Some books — known as "sharp" books — are better at setting accurate lines because they accept large bets from professional bettors. These sharp lines serve as a baseline for true probability.
When 10+ sportsbooks all offer odds on the same event, the aggregate of those odds provides a powerful signal. Edge analyzes the full market to determine where the consensus lies and which books are outliers.
Edge's models are continuously validated against actual outcomes. We track how well our fair value estimates predict reality, and we refine the models based on that performance data.
When odds move sharply at one book, it often indicates new information. Edge factors in line movement patterns to adjust fair value in real time.
Here's how to incorporate grades into your betting strategy:
Instead of starting with a game and looking for bets, start with Edge's best grades. Filter for A and B grades, then evaluate those specific opportunities. This flips the traditional approach on its head and ensures you're always betting into value.
Have a bet you like? Check the grade before placing it. If it's a C or above, go ahead. If it's a D or F, consider whether there's a better number elsewhere — or whether the bet is worth taking at all.
Over time, track your results by grade. You should see that your A and B grade bets perform significantly better than your D and F grade bets. This validates the system and builds confidence in following the grades.
No. An A grade means the bet has positive expected value — the odds are in your favor. But any individual bet can still lose. Value betting is about long-term mathematical edge, not guaranteeing individual outcomes.
Grades update in real time as odds move. If a sportsbook adjusts their line, the value of that bet changes. An A-grade bet that gets bet down to shorter odds might become a B or C.
Generally, no. If you're serious about profitable betting, you should stick to C grades and above. Consistently betting D and F grades is a recipe for long-term losses because the math is working against you.
No! The same game can have an A grade at one sportsbook and a D grade at another. That's because different books offer different odds. Edge shows you the grade at each book so you can always take the best number.
The beauty of the grading system is its simplicity. You don't need to understand implied probability calculations or expected value formulas. Just look at the letter grade. A and B = bet. D and F = pass.
This democratizes value betting. Whether you're a seasoned sharp or a casual fan who likes to bet on the weekend, the grades give you the same edge.
