Understanding Prediction Markets:

Prediction markets, such as Polymarket, operate on the principle of collective intelligence. The probability assigned to an event reflects the aggregated belief of traders. A probability of 0.705, for example, means that traders, on average, believe there is a 70.5% chance of that outcome occurring. Conversely, a probability of 0.115 signifies a 11.5% implied chance. Prices move based on supply and demand for the outcome shares. When more people want to buy shares of an outcome, its price and implied probability increase. When more people sell, the price and probability decrease. These markets are dynamic and can change rapidly based on new information or shifts in sentiment.
