Understanding Polymarket Probabilities:

Polymarket operates as a prediction market where users can buy and sell "shares" in the outcome of events. The price of a share reflects the market's current consensus probability of that outcome occurring. For instance, a share trading at $0.20 implies an 80% probability of that outcome occurring (20 cents per dollar of potential payout). Conversely, a probability of 8% means a share is trading at $0.08, indicating the market collectively assesses an 8% chance of that specific outcome. These probabilities are dynamic and can change based on user trading activity, which is influenced by new information, analysis, or sentiment shifts.
