Polymarket Odds Converter

Polymarket prices are quoted in cents (0.00–1.00). For anyone used to sportsbook odds — decimal, American, or fractional — those numbers are hard to read at a glance. This extension drops the converted odds in next to every Polymarket price.

What it does

Reads every visible Polymarket price on the page and renders its decimal, American and fractional equivalents next to it. Updates as you scroll and as prices move.

How to use it

Open any market on polymarket.com.
The converted odds appear automatically next to each price tile.
Toggle which formats are shown from the extension popup.
