What Is a Value Bet? The Complete Guide for 2026

What Is a Value Bet?

A value bet is when your estimated probability of an outcome is higher than the probability implied by the bookmaker's odds.

For example:

• You think Team A has a 60% chance of winning
• DraftKings offers odds of +120 (implied probability: 45%)
• The difference (60% - 45% = +15%) is your edge

This is positive expected value (+EV).

How to Calculate Value Bets

Step 1: Convert odds to probability

For American odds:

• Positive odds (+120): 100 / (120 + 100) = 45.5%
• Negative odds (-150): 150 / (150 + 100) = 60%

Step 2: Compare to your probability

If your probability > bookmaker probability = value bet

Step 3: Calculate edge

Edge = Your probability - Bookmaker implied probability
