Bookmaker Odds Comparison — How to Find Value Bets (World Cup 2026 Examples)
Why Odds Comparison Matters
The same match can have significantly different odds across bookmakers. For Brazil vs Norway Over 2.5 in the R16:
- Bookmaker A: @1.72
- Bookmaker B: @1.75
- Bookmaker C: @1.80
Over 100 bets, this difference translates to thousands in profit. OddsFlow automates this by collecting real-time odds from 10+ bookmakers.
What Is a Value Bet?
A value bet exists when the bookmaker's odds imply a lower probability than the true probability.
Formula: EV = (Win Probability x Profit) - (Loss Probability x Stake)
Example: Portugal vs Spain Under 2.5 @1.72
- OddsFlow model: 62% probability of Under 2.5
- EV = (0.62 x 0.72) - (0.38 x 1.00) = +6.64%
- Positive EV = Value bet
