What this price means
A 52.4¢ contract pays $1 if it wins, so the market rates this outcome a 52.4% chance. A sportsbook quotes the same price as -110.
How each format worksWhat each format means
Price in cents
A prediction market contract costs a number of cents and pays $1 if it wins, so the price is the market's implied probability. 52.4¢ is a 52.4% chance.
American
Negative odds show the stake needed to win $100, so -110 risks $110. Positive odds show what $100 returns in profit, so +200 wins $200.
Decimal and fractional
Decimal is the total return on $1, stake included, so 1.91 returns $1.91. Fractional is profit against stake, so 10/11 wins $10 for every $11 risked.
Your return
Divide your stake by the price. A $100 bet at 40¢ returns $250. The lower the price, the more a winner pays back.
