Any advantage a bettor has over the bookmaker or casino on a specific wager.
An edge is any mathematical advantage you have on a bet. In casino games, the house always has the edge (the house edge). In sports betting, an edge means you've found a bet where the true probability of winning is higher than what the odds imply.
Edge can come from many sources: superior information, better models, exploiting slow-moving lines, taking advantage of promotions, or finding pricing mistakes. The key is that your edge must be large enough to overcome the vig.
Without an identifiable edge, you're gambling — not investing. Professional bettors can articulate exactly where their edge comes from for every wager they make.
A sharp projects a Warriors-Suns total at 228.5 using a team-pace and efficiency model, while Caesars posts the line at 231.5 Under -110. The 3-point gap between fair value and market price creates a measurable edge: at -110 the break-even is 52.38%, but the model implies the Under hits closer to 57%.
Expected value per $100 bet is (0.57 × $90.91) − (0.43 × $100) = +$8.82, a 4.4% edge. Over 500 bets at $100 each, that projects to roughly $4,400 profit. Edge shrinks quickly as bet limits increase and the market corrects, so sharp bettors hit early-week numbers at Pinnacle and Circa before public money compresses the gap.
