THE BIGGEST OPEN MARKETS
Where the money is.
Live implied probabilities for the largest open prediction markets.
Reading the charts
Each line is the price of a “Yes” share in dollars, which the market treats as the probability of that outcome. Multi-outcome events show their five likeliest outcomes; independent ladders show their five most traded. Prices step from one observation to the next and are not advice.
Straight from the source
Rankings use open markets only. Prices refresh every 30 seconds and history every minute through public APIs; no account or key is used. Times are shown in your local time zone.
