A decline in probability suggests that, based on current information and trading, participants perceive a reduced likelihood of the event materializing.

Understanding Prediction Markets

Prediction markets, like Polymarket, allow users to bet on the outcome of future events. The probability assigned to an event is determined by the trading price of a contract that pays out if the event occurs. For instance, a contract trading at $0.50 implies a 50% probability of the event happening, assuming efficient market pricing. These markets are distinct from traditional polling or forecasting methods, as they aggregate information through financial incentives.
