How it works
- 01No-vig fair odds
Fair price
For each market, Betwatch takes the prices of the sharpest books and removes their margin (the vig) with the power method. What is left is the fair chance of each outcome.
- 02Expected value
Edge
Each book's price is compared with the fair chance. The edge, in percentage points, is how far the fair chance sits above the chance the price implies. A positive edge is a +EV bet.
- 03Sharp books
Evidence
On the default board each bet shows the books behind its fair price and how many of them are sharp, so you can judge how far to trust the edge.
- 04Pregame markets
Pregame only
The default board lists pregame bets only. A signed-in board syncs every 55 seconds.

Questions
What is a +EV bet?
A +EV (positive expected value) bet is one whose price pays more than the outcome's true chance is worth. For example, decimal odds of 2.05 imply a 48.8% chance. If the fair chance is 52.4%, the bet is +EV by 3.6 percentage points. Over many bets a +EV bet should profit, but any single one can lose.
How does Betwatch find +EV bets?
It builds a fair line for each market from the sharpest books, with the vig removed (the power method), then compares every other price against it. Bets that pay more than fair are ranked by edge, and each one lists the books behind its fair price. The default board covers pregame markets only.
Is the +EV tool free?
Yes, it is free during beta. Signed-out visitors see the single best bet. A free account unlocks every bet and the filters, and no card is required.
Which sportsbooks does it cover?
Betwatch compares odds from 42 odds sources (27 of them sportsbooks). The +EV board prices sportsbooks, betting exchanges and pick'em apps such as PrizePicks and Underdog. Switch off the books you do not use in your account settings and they leave the board.
Is a +EV bet a sure win?
No. A +EV bet wins less often than it loses at long odds and can lose many times in a row. The edge shows up over a large number of bets, and a price can move before you place it. Check that the sharp books agree before trusting a large edge.
