Polymarket Context:

Prediction markets, like Polymarket, function by allowing users to bet on the outcome of future events. The probability displayed represents the market's collective belief about the likelihood of a specific outcome occurring. A higher probability (closer to 100%) indicates the market assigns a greater chance of that outcome happening, while a lower probability (closer to 0%) suggests it is less likely.

Probabilities are determined by the buying and selling of market shares. If more participants are buying shares representing an outcome, its probability increases. Conversely, if shares are being sold, the probability tends to decrease. These probabilities are dynamic and can change rapidly as new information becomes available or as market participants adjust their positions.
