Reading the odds

A prediction market trades contracts that pay $1 if something happens. Its price is the market's chance: a contract at 62¢ means traders give it 62%. Each number here is the midpoint between the best bid and offer, or the last trade when they are more than ten cents apart.

For a question with many answers (who wins, which range a number lands in), the chances are scaled to add up to 100%. A price ladder ("above 4.25%, above 4.50% ...") gives a whole distribution: its median is where traders see an even chance either way.

Kalshi is a U.S. exchange regulated by the CFTC; its money is counted in contracts, shown here as dollars at their price. Polymarket counts dollars. ForecastEx is Interactive Brokers' exchange, regulated by the CFTC; its contracts too are shown as dollars at their price. Crypto.com lists its markets on Crypto.com | Derivatives North America, a U.S. exchange regulated by the CFTC; it reports the dollars traded. Where more than one asks the same question, each is shown, never averaged.

Prefer betting odds? Switch to American (+150) or decimal (2.50) odds at the top of the page.
