When both sides are mispriced at once
Every row above is one side of one bet, taken because the price is better than the outcome is worth. Occasionally two venues disagree far enough that both sides of the same bet can be backed at once for less than a certainty — and then the outcome stops mattering entirely.
In short
This board lists every live prop bet where a prediction market — Kalshi, Polymarket or Novig — is pricing a player prop or game line cheaper than every sportsbook quoting the same outcome. Each row is ranked by percentage points of win probability: fair value is PropLine's de-vigged price where one exists, or the de-vigged median of at least two sportsbooks on the same bet, and the edge is how much cheaper the best venue's price is than that fair line. It covers NFL, NBA and MLB, filterable by sport, market and minimum edge for subscribers.
Live edges FAQ
What counts as an edge on this board?
A prop where a prediction market's price is cheaper than the fair line implied by sportsbooks on the same outcome — PropLine's de-vigged price where one exists, or the de-vigged median of at least two sportsbooks otherwise. The edge is how many percentage points of win probability the best price saves against that fair line.
Which sportsbooks and prediction markets does this board compare?
Kalshi, Polymarket and Novig on one side, checked against every sportsbook pricing the same outcome, across NFL, NBA and MLB player props and game lines.
Can I filter the edge board by sport, market or minimum edge?
Yes — the filters above the board narrow it by sport, market and a 2% or 5% minimum edge. Filtering is a BeatVig Premium feature; a free visitor sees the board's default ranking, truncated to a sample.
How is this different from the odds comparison page?
The odds comparison page ranks every bet by how much more the best price pays against the median of the rest of the market, with no view on who is right. This page only lists props where a prediction market is pricing an outcome cheaper than every sportsbook, which is a claim about probability rather than just about price.
How often does the edges board update?
Continuously. PropLine delivers price updates throughout the day and this board subscribes to them directly, so a row's price and edge change in place as sportsbooks and exchanges reprice, with no page reload needed.
