← How It Works Fair Value Model

See whether the price you're getting is actually worth betting.

Every sportsbook prices the same game slightly differently. The Fair Value Model strips out each book's margin, blends the market into a single fair probability, and compares that against the best price available so you can see whether a bet is priced in your favor before you place it.

What it helps you do

Decide whether a price is worth taking.

Sportsbooks set odds that include their own margin, so the number you see is never a clean read of the true probability. The Fair Value Model answers a simple question for any moneyline, spread, or total: given what the market as a whole is saying, is the best available price better or worse than it should be?

That's the decision behind almost every bet: not "who wins," but "is this number worth betting at."

Why it matters

The same bet can be priced differently everywhere.

Odds move for reasons that have nothing to do with which side is more likely to win: liability, promotions, and how fast one book updates relative to another. That creates real gaps between what different sportsbooks are charging for the same outcome.

Comparing a single sportsbook's price to your own gut feel does not tell you much. Comparing it to a fair, no-vig market baseline does. That baseline is what the model provides.

How it works

From sportsbook prices to a fair baseline.

1. Pull the latest market

The model reads the newest sportsbook prices for your selected date window and keeps only the games in scope.

2. Match comparable sides and lines

Moneyline sides are paired together, and spreads and totals are matched by the same line number before anything is compared.

3. Remove each book's margin (de-vig)

Every sportsbook builds in a margin so both sides of a bet add up to more than 100%. Each book's market is rebalanced to a true 100% before it's used.

4. Build a weighted consensus

The de-vigged probabilities from every included sportsbook are blended, giving more influence to stronger price-setting books, into one fair probability per side.

5. Convert probability into fair odds

The consensus probability is translated into a zero-margin price, so you can compare it directly against what sportsbooks are actually offering.

6. Find the best available price

The model scans the sportsbooks you've selected and surfaces the most favorable live price for each pick.

7. Calculate expected value (EV%)

EV% compares the best real payout against the fair probability. A positive number means the price pays more than the consensus says it should.

8. Apply your filters

Market, minimum EV, minimum odds, selected sportsbooks, and odds format determine what appears. Negative-EV bets stay hidden by default.

How to use it

A practical workflow.

  1. Choose a date range and, optionally, a specific market.
  2. Select the sportsbooks you actually have access to.
  3. Set a minimum EV% or odds threshold if you only want to see stronger opportunities.
  4. Sort by EV% to see where price and fair value disagree the most.
  5. Open Matchup Center or Prop Research on anything that looks interesting before deciding.
How to interpret the output

What each column means.

Fair Odds
The American-odds equivalent of the weighted, no-vig sportsbook consensus. This is the model's estimate of a fair price, not a prediction of the winner.
Best Book / Best Odds
The sportsbook, among those you've selected, currently offering the most favorable price for that pick.
EV% (Expected Value)
How favorable the best available price is compared with the fair, no-vig baseline. Higher is more favorable, not more certain.
Market
Moneyline, spread, or total. Fair odds and EV% are only meaningful within the same market and line.
What it does not mean

Positive EV describes the price, not the outcome. A positive-EV bet can still lose, and a negative-EV bet can still win.

Fair odds are a market-based estimate, not a guarantee of the true probability. The consensus can be wrong, especially in thin or fast-moving markets.

A single positive-EV bet says nothing about your results on that bet. Edge is a property of a price, evaluated over many decisions, not a promise about any one wager.

The model is a research input, not a recommendation. Matchup context, injuries, and your own judgment still matter.
