What are value bets and how AI finds the edge

July 7, 2026 · 5 min read

Over the long run, sports analytics is not about picking the winner. It is about finding value: when the odds are higher than they should be for the real probability. Here is what that means.

What value is

Value shows up when your estimate of a result's probability is higher than the one baked into the odds. In plain terms, the bookmaker underrated that result and the price is too high for the real risk.

The value formula

Value = Probability (yours) × Odds − 1

Above zero means you have an edge. Example: you rate a result at 55% (0.55) and the odds are 2.00. Value = 0.55 × 2.00 − 1 = +0.10, a +10% edge. At odds of 1.70: 0.55 × 1.70 − 1 = −0.065 — no edge, bad bet.

Why value beats guessing

You can hit 6 of 10 and still lose money taking short odds. You can hit fewer, always with an edge, and finish ahead. What decides it is the math edge on each bet, not the hit rate.

How to find value

You need two things:

The gap between the two is a value candidate. That is what the deVIG engine does on Pro: it compares its own probability with the market and flags the edge.

Value does not guarantee any single bet. It works over the long run, and only with discipline and bankroll control.

Where AI comes in

Finding value by hand is slow. You would have to devig every line and cross it with your own estimate across dozens of matches a day. The deVIG AI does it in seconds, runs a Monte Carlo simulation and measures expected value on each market. You get the read ready, with the match analysis.

What to keep in mind

Chasing value is not guaranteed profit. Over a short run any streak happens and the model can be wrong. Value is about long-run expectation, not a single match.

Don't guess. Calculate.
