Frequently asked questions

Generally, prediction market odds often reflect a wisdom-of-the-crowd effect, potentially differing from traditional sportsbook odds.

If sportsbooks heavily favor one player, you might see a different probability distribution here, especially if there’s significant disagreement or new information emerges. It’s common to see discrepancies, as prediction markets can incorporate a wider range of factors and react more quickly to changing circumstances than traditional betting venues.
