Understanding Prediction Markets
Prediction markets, like Polymarket, operate on the principle of collective intelligence. Participants buy and sell contracts whose value is tied to the outcome of future events. The price of a contract reflects the market's aggregate probability assessment of that outcome occurring. For instance, a contract trading at $0.20 implies a 20%% probability that the event will occur.
