What it does

What Prop Discrepancies helps you review

Ranks player props by line discrepancy across supported Books.
Lets users filter by Sport, League, Book count, and multiplier context.
Covers every live league where the connected Books currently have supported inventory.
Calculates each discrepancy from Books offering both Over and Under selections, excluding identical lines and suspended one-sided markets.

Best fit

Who this tool is for

Adult sports bettors and analysts who compare player-prop lines across DFS and prediction platforms.
Users researching traditional sports or esports where Upside has live multi-Book coverage.
Users who want one consistent workflow for moving between a busy baseball slate, basketball props, football markets, and esports without changing tools.

Markets and platforms

Coverage depends on supported books, markets, and user location

Player props across live traditional-sport and esports leagues where supported Book data is available.

Coverage varies by slate, book, market type, and user location.

Upside scans 30+ sportsbooks, DFS apps, exchanges, and prediction markets across the product, but each tool has its own coverage rules and data availability.

Workflow

What to check before making your own decision

Filter to a Sport and League

Start with the Sport or League you understand best, then narrow the Books and minimum coverage required for each row.

Use book count as context

A discrepancy with more books behind it can be easier to review than a row based on one or two isolated prices. The tool keeps book count visible for that reason.

Compare the size of disagreement

Review the spread percentage and the books driving it. The goal is to find markets worth investigating, not to force action on every listed row.

Cross-check before acting

Use the EV Calculator, No-Vig Calculator, or Odds Screen context to translate a discrepancy into price and probability before making your own decision.

Before relying on the data

  • Is the discrepancy supported by enough books to make the row worth reviewing?
  • Could roster news, patches, map pools, or market timing explain why one platform is different?
  • Does the price still make sense after checking implied probability and book availability?

Questions

Common Prop Discrepancies questions

What is the Prop Discrepancies tool?

Prop Discrepancies compares supported player-prop lines and ranks rows by how much Books disagree.

Which sports and leagues are supported?

The page discovers live leagues from the odds service and shows those with current inventory from supported Books. Availability changes by slate and platform, so a league with no current supported lines will not be shown as active coverage.

Why do esports discrepancies appear?

Esports markets can be slower to update because of smaller handle, roster changes, patches, and map-specific information. The tool helps users review those gaps more quickly.

How should users treat a large discrepancy?

A large discrepancy is a research prompt, not a command to act. Users should check book count, market freshness, lineup context, and the live sportsbook price first.
