How to find positive EV bets

A positive EV bet is a bet whose payout is higher than its fair odds. To find positive EV bets, you need a fair price for each side of a market and a sportsbook paying more than that fair price. The short version is six steps: take a sharp book's two-sided price, remove the vig, shop the same bet across US sportsbooks, calculate EV, set a minimum EV you'll act on, and check your price against the closing line afterward.

Positive EV is a long-run math estimate. A single +EV bet loses often, and nothing here promises a win or a profit.

LineGoat runs a morning scan that follows these six steps and logs every result on the public Edge Tracker, losses included. The scan's filters and grading are on how Edge of the Day works. This guide shows how to do the same steps yourself, and what 39 real edges from that scan looked like.

A sharp book is a sportsbook whose prices move toward the true odds because it accepts large bets from skilled bettors. LineGoat's scan uses Pinnacle as its sharp reference. Pinnacle lines are used only as a sharp reference price; LineGoat doesn't promote betting at Pinnacle. You need both sides of the market (Team A and Team B, or the favorite and the underdog on the same spread number), because Step 2 compares the two sides against each other.

Use a market with exactly two outcomes. A three-way soccer market or a futures board needs a different calculation.

The vig is the bookmaker's margin. Convert both sides to implied probabilities and they add up to more than 100%; the extra is the vig. Removing it gives the fair probability.

The most common way is the multiplicative method: divide each side's implied probability by the total of both. LineGoat's scan uses that method too.

Hypothetical example (made-up prices, for illustration only): a sharp book prices Team A at +150 and Team B at −170.

• Team A +150 = 2.50 decimal, implied probability 40.00%
• Team B −170 = 1.588 decimal, implied probability 62.96%
• Total = 102.96%, so the vig on this market is about 2.96%
• Team A fair probability = 40.00% ÷ 102.96% = 38.85%
• Team A fair odds = 2.574 decimal = +157

If you don't want to do this by hand, the Crazy Ninja Odds devigger is free and offers six devig methods. The full math, with more examples, is in how to read a no-vig line, and the one-page no-vig cheat sheet has the formulas.

Now look for Team A at the US sportsbooks you can legally use, on the same market and, for spreads, the same number. A +3.5 price can't be compared with a +3 price. An odds screen does this in one view. The best free odds screens for +EV betting page ranks the free options by what they give away.

Shopping matters because the best price moves around. In LineGoat's scan, the best US price came from seven different sportsbooks across 39 edges (details below). Which book wins most often in our data: which sportsbook has the best odds.

In the hypothetical example, say one US book offers Team A at +170 while the others sit at +150 to +160.

EV = fair probability × decimal odds at the best book − 1

Team A at +170 is 2.70 decimal. EV = 0.3885 × 2.70 − 1 = 0.049, or +4.9% EV.

That means a long run of bets priced like this one would return about 4.9 cents per dollar staked on average, if the 38.85% fair probability is right. Team A still loses about 61 times in 100 by the same math. At that win rate, losing five such bets in a row happens about 8.6% of the time.

A fair price is an estimate, so a tiny EV can be an error in the estimate rather than an edge. Pick a minimum and skip everything below it. LineGoat's own scan band and freshness rules are on how Edge of the Day works; for DIY work, pick a floor you will stick to before you shop.

The devig method you choose changes the answer, mostly on longer prices. In the hypothetical example, the additive method (subtract half the vig from each side) gives Team A a fair probability of 38.52% instead of 38.85%, and EV at +170 drops from 4.9% to 4.0%. On a +350 underdog with a wider margin, the gap between methods can be several points of EV. If an edge only clears your minimum under one method, treat it as thin.

Also check that the price is still current before you bet. Stale quotes are a common false edge.

Closing line value (CLV) compares the price you got with the sharp book's fair price just before the game starts. Positive CLV means you beat the final market.

Hypothetical close: the sharp book closes Team A at +140 and Team B at −160. Devigged, Team A's closing fair probability is 40.37%. CLV = 0.4037 × 2.70 − 1 = +9.0%. The +170 you took beat the close by a wide margin, whatever the score.

CLV is useful because every bet gets a CLV number, win or lose, while results swing a lot over small samples. It's an estimate, too. More on the method: what closing line value is.

LineGoat's Edge Tracker logs every edge the morning scan has published since Oct 16, 2026. These figures come from the Edge Tracker data CSV, pulled Oct 31, 2026 (39 edges, 29 graded, 10 pending).

Three things stand out for anyone doing this by hand.

Most edges are underdogs. 27 of 39 edges were priced at +200 or longer. Longer prices give bigger EV swings from small errors in the fair price, and the multiplicative method gives underdogs a slightly higher fair probability than other methods do. Expect long dry spells between wins.

Some days have nothing. The CSV has no edge on 6 of the 16 days. Skipping a day is part of the method; a lower bar would only mean publishing weaker prices.

The record and the CLV can disagree. 7 wins from 29 graded edges is below the 9.9 wins the fair odds expected, while 12 of 19 tracked edges beat the closing line. 29 bets is a very small sample, and neither number proves anything yet. That's why we publish both.

• Prices move. An edge can disappear minutes after you find it. LineGoat grades at the price published at scan time, which may not be the price you can get later.
• Books can limit winning accounts. The Massachusetts Gaming Commission's Sports Wagering Division reported in September 2025 that, across licensed Massachusetts operators, players who consistently beat the closing line were more likely to have their bet limits lowered. On average, 0.64% of Massachusetts player accounts were limited as of Dec 10, 2024.
• Not every book is in every state. Check where sports betting is legal and use only books licensed where you are.
• The sharp price can be wrong. It's the best available estimate of the true odds, not the truth.

What is a positive EV bet?

A positive EV bet is a bet whose payout is higher than its fair odds, so its expected return per dollar staked is above zero over many bets. EV = fair probability × decimal odds − 1. A single +EV bet can still lose.

How do you find positive EV bets?

Take a sharp book's price on both sides of a market, remove the vig to get the fair probability, find the best price for the same bet at US sportsbooks, and calculate EV. Act only on prices above a minimum EV you set in advance, then compare your price with the closing line.

What is a good EV percentage?

There's no published standard. LineGoat's scan uses a 1% minimum and drops anything above 12% as a likely stale or wrong line. The median edge in LineGoat's tracker was 2.8% EV (39 edges, pulled Oct 31, 2026).

Do positive EV bets always win?

No. In LineGoat's tracker, 7 of 29 graded +EV edges won (CSV pulled Oct 31, 2026), against 9.9 expected wins at fair odds. Results over small samples swing a lot.

Can I find positive EV bets for free?

Yes. A free odds screen plus a free devigger covers Steps 1 to 4 by hand. LineGoat ranks the free odds screens on best free odds screens for +EV betting.

Why does closing line value matter for +EV betting?

CLV shows whether your price beat the sharp market's final price, and every bet gets a CLV number whether it wins or loses. That makes it a faster check on your process than results alone.
