Frequently asked questions

On Polymarket, the current probability reflects trader sentiment rather than traditional sportsbook lines. Sportsbook odds often factor in house margins and broader public betting trends, which can create differences in implied probabilities.

As a result, the market price captures the collective expectation of Polymarket participants at any given moment.
