How to read each format
Polymarket PriceThe price of a share in PUSD. A $0.65 share implies a 65% probability. If correct, you receive $1.00 per share.
Implied ProbabilityThe percentage chance the market assigns to an outcome. 65% means the market thinks there is a 65-in-100 chance.
Decimal OddsYour total return per $1 staked, including your stake. Decimal 1.54 means $1.54 total return on a $1 bet ($0.54 profit).
American OddsFavorites show how much you must risk to win $100 (e.g. -186). Underdogs show how much you win on a $100 stake (e.g. +154).
Fractional OddsProfit relative to stake as a fraction. 13/20 means $13 profit for every $20 staked. Common in UK betting.
Hong Kong OddsProfit per unit staked, like decimal odds minus 1. HK 0.54 means $0.54 profit on a $1 stake.
Malay OddsPositive (0 to 1) for underdogs showing profit per unit staked. Negative for favorites showing the stake needed to win 1 unit.
Indonesian OddsSimilar to American odds but based on 1 unit instead of 100. Negative for favorites (risk to win 1), positive for underdogs (win per 1 staked).
All conversions use implied probability as the canonical intermediate. Fractional odds are simplified using the greatest common divisor. American odds are rounded to the nearest integer.
Understanding Odds Formats
