# +EV Scanner

> Find positive expected-value opportunities.

The **+EV Scanner** compares odds across sportsbooks to find bets priced better than their true probability — **positive expected value**. Open it with <kbd>/</kbd> → `PEV`.

## Running a scan

<Steps>
  <Step title="Pick a sport">
    Choose a league from the dropdown — NFL, MLB, soccer leagues, and dozens more.
  </Step>

  <Step title="Choose your books">
    The **Books** selector controls which sportsbooks to compare. Pick the ones you can actually bet with.
  </Step>

  <Step title="Scan">
    Hit **Scan** to sweep current lines. Turn on **Auto** to keep rescanning so fresh edges surface as lines move.
  </Step>

## Reading the results

| Column                  | What it tells you                                                           |
| ----------------------- | --------------------------------------------------------------------------- |
| **Game / Player / Bet** | What the wager is (moneyline, total, prop)                                  |
| **Book**                | Which sportsbook has the mispriced line                                     |
| **Odds**                | The price on offer                                                          |
| **EV%**                 | Your edge — the average profit per dollar if this bet were repeated forever |
| **True%**               | The consensus probability implied by the sharpest available lines           |
| **Kelly**               | The stake the Kelly criterion suggests, as a % of bankroll                  |
| **Bet**                 | That stake in dollars                                                       |

## How it finds an edge

The scanner treats the consensus of many books (weighted toward the sharpest) as the *true* probability of an outcome. When one book lags — slow to move after news, or simply off-market — its stale line is an edge. Bet it at better-than-true odds, and over many bets the math works in your favor.

<Note>
  +EV betting is a long game: individual bets still lose all the time — the edge shows up over volume. The **Kelly** column exists to keep any single bet small relative to your bankroll.
</Note>

<Tip>
  Prediction markets often price the same games as sportsbooks. Cross-check a +EV line against the equivalent Kalshi/Polymarket market in the [Odds](/panels/odds) panel — when both agree the book is off, that's a stronger signal.
