An Edge in Dimers is a measure of how much value exists in a bet compared to the sportsbook’s odds. It tells you whether a bet is advantageous, neutral, or negative based on Dimers’ predictive model.
In simple terms:
Edge = How much better (or worse) a bet is compared to what the sportsbook is offering.
The higher the Edge, the more potential value a bettor may have on that selection.
Every sportsbook line reflects an implied probability. Dimers compares that implied probability to our model’s projected probability of the outcome happening. The difference between the two is the Edge.
Sportsbook odds imply a 45% chance of Team A winning
Dimers projections show a 52% chance of Team A winning
Difference = 7% Edge
This means Dimers believes the real probability is 7% higher than what the sportsbook is pricing — creating potential value.
Betting value—not just picking winners—is the key to long-term success.
Even good bettors lose in the long run if they consistently bet into negative expected value (-EV) lines.
A positive Edge:
Indicates a bet the sportsbook may be mispricing
Suggests better long-term expected results
Helps identify opportunities where the model sees an advantage
A negative Edge means the sportsbook price is worse than the true probability, so Dimers does not recommend betting it.
Edge appears across various Dimers tools, including:
Best Bets
Parlay Picker
Game and player prop projections
Dimebot recommendations
Matchup detail pages
Whenever Dimers highlights a bet, it usually includes:
Win probability
Sportsbook odds
Edge %
This gives you full transparency into why the model likes that bet.
While a high Edge can signal strong value, it does not guarantee a better bet or higher likelihood of success. There are several reasons why an unusually high Edge may appear:
This could include:
Late-breaking injuries
Lineup changes
Weather updates
Market movement
Insider or sharp action
If sportsbooks have adjusted based on this information and the model hasn’t yet incorporated it, Edge may appear artificially high.
Although rare, extreme edges can occur if:
Odds haven’t updated yet
A line is missing or mispriced in the feed
There’s a glitch in a data source
Dimers monitors these issues, but outlier edges can still appear occasionally.
Some markets—especially longshot props—naturally produce wider swings in Edge because:
Small changes in probability create big changes in value
The model’s confidence bands are wider
A high Edge does not always equal a low-risk bet.
Treat extremely high edges with caution.
Use them as part of your decision-making process, but consider context, matchup details, and your own risk tolerance before placing a bet.
Extreme edges are signals, not guarantees.
Dimers’ goal is to help bettors make smarter, data-backed decisions.
Spot mispriced lines
Identify long-term profitable opportunities
Prioritize quality bets over gut-feel plays
Even if a bet looks appealing, if it doesn’t have Edge, the model considers it not worth it.
