What Is Betting Value and Why It’s the Key to Sports Betting Profitability
Edward GlushUnderstanding and Finding Betting Value in Sports
In the world of sports betting, the difference between gambling and investing often comes down to one core concept: Betting Value.
It's not just about picking winners — it's about identifying wagers where the odds offered by the sportsbook are more favorable than the true probability of the outcome occurring.
At Bet Better, spotting this value is at the heart of our methodology.
What Is Betting Value?
Betting value — often called positive expected value (+EV) — occurs when the implied probability of an outcome (based on betting odds) is lower than your calculated probability.
Example: Coin Flip
A fair coin flip has a 50% chance of heads.
If a sportsbook offers 2.10 decimal odds (+110 American), they’re implying a 47.6% probability.
Since your estimated chance is 50%, this is a value bet — over time, you’d profit from this discrepancy.
Why Focus on Value?
Betting value is the only reliable path to long-term profitability.
Even if you don’t win every bet, consistently backing outcomes where you have a statistical edge leads to profit over many wagers.
Betting without value = gambling.
Betting with value = strategy.
How Bet Better Finds Value
We don’t guess — we model. Bet Better combines:
AI + Machine Learning: Models trained on massive datasets produce accurate probabilities for outcomes, props, and player stats.
Actuarial Math: We apply the same statistical rigor used in insurance and finance.
Market Odds Comparison: We scan live odds across sportsbooks and compare them to our calculated probabilities.
When our calculated probability is higher than the implied probability from the market, we flag it as value.
Implied Probability vs. True Probability
Sportsbook Odds: Reflect their assessment plus a margin (vig).
Implied Probability: Derived from odds (e.g., 2.50 odds = 1 / 2.50 = 40%).
True Probability: Your model’s best estimate — or in our case, Bet Better’s AI output.
Example:
A team has odds of 2.50 (40% implied probability).
Our models estimate a true probability of 45%.
That 5% difference is value.
How to Act on Value Bets
We surface bets where our models show a positive expected value — not guaranteed wins, but statistically favorable wagers.
Use these to build your edge over time, applying disciplined bankroll management and avoiding emotional betting.
