Understanding Prediction Markets:

Polymarket operates on a system of prediction markets where users can buy and sell shares in the outcome of future events. The price of a share, expressed as a probability (e.g., 70%), represents the market's collective belief about the likelihood of that outcome occurring. A probability of 50% suggests a coin-flip scenario, while probabilities closer to 0% or 100% indicate a stronger consensus. A decrease in probability for one outcome implies an increase for the alternative outcome(s) or a general decrease in the perceived certainty of any single outcome resolving positively for its proponents. The data provided reflects the current consensus of the market participants.
