Market profile and overround. Overrounds range from 91.5% (888sport) to 99.3% (Matchbook), reflecting overall significant margins. Pinnacle sits at 97.8%, consistent with a reference line. French books (PMU 92.9%, Winamax 93.9%) and German operators (888sport 91.5%, William Hill 92.5%) offer the tightest margins, while Matchbook and trading platforms (Betfair 99.1%, 1xBet 98.5%) display higher overrounds.
Odds distribution by outcome. On Colombia's victory, offers range from 3.25 (888sport) to 3.70 (Betfair, Matchbook, BetOnline.ag), a 14% spread reflecting clear segmentation between low-margin and premium operators. The draw concentrates between 3.50 and 3.96 (Pinnacle), with minimal volatility. Portugal's win hovers around 2.00–2.08 (Matchbook); this stability signals market consensus on this outcome.
Value signals. Betfair and Matchbook offer 3.70 on Colombia versus Pinnacle's fair odd of 3.62, generating potential value of +2.2%. This edge is marginal but exploitable, especially if accumulated across multiple decisions. No value emerges on the draw (max 3.96 vs fair 4.05, slightly underpriced) or Portugal's win (max 2.08 vs fair 2.10, minor discount). The optimal overround, combining best odds across all outcomes, reaches 99.6%, in line with a mature market.
Practical guidance. To capture this value, favour Betfair on a Colombia win (3.70) if match analysis supports it; avoid 888sport, whose offer (3.25) introduces substantial underpricing. CalculaBet's tools (Value Bet, Overround, Surebet calculators) enable precise validation against your own forecasts. Remember: odds shift continuously—verify live pricing before committing.
