Whether you use a prediction market or a sportsbook, Propability turns odds from any app into one plain chance and lines the apps up side by side on the same prop.
A 55¢ contract and -122 odds both mean about a 55% chance. We do that math for every prop we cover, whichever app it comes from.
The same prop from different apps, side by side, each as one plain chance, so you can see which pays more.
We show the fair chance with the app's built-in cut taken out, in plain words. You decide what, if anything, to do with it.
Each prop with its plain chance and the fair chance, app by app, in one row. Sort and filter by game, player or stat.
See how different apps line up on the same prop, so you can spot where they differ.
Tell us your state and which apps you use, and Propability leans toward the markets you can actually reach.
Short notes on why a number moved, no jargon, so the math is easy to follow even if you're new to it.
