Understanding Prediction Markets:

Polymarket operates as a decentralized prediction market. The probability displayed on a market, such as the 27.5% for a confirmed Hantavirus case by May 15, represents the collective belief of market participants regarding the likelihood of that event occurring. This probability is derived from the trading prices of market "shares," where a share trading at $0.50 implies a 50% probability.

Prediction markets are dynamic and probabilities can change rapidly based on new information, public sentiment, and trading activity. They are not endorsements or confirmations of events but rather reflections of information available to participants at a given time. Changes in probability, such as the 46% decrease observed, indicate shifts in the market's aggregated assessment of the event's likelihood.
