Understanding Prediction Markets:

Prediction markets, such as Polymarket, allow users to trade contracts based on the likelihood of future events. The price of a contract reflects the market's current consensus probability of that event occurring. For instance, a contract trading at $0.50 suggests a 50% probability, while a contract at $0.01 implies a 1% probability. Probabilities are calculated as the current price of the contract. These probabilities are dynamic and can change based on the collective assessment of market participants as new information becomes available or as the event date approaches. It is important to note that these probabilities represent the market's aggregate forecast and not a guarantee of the event's outcome.
