Context on Prediction Markets:
Prediction markets, such as Polymarket, function similarly to financial markets. Participants buy and sell contracts whose value is tied to the outcome of future events. The price of a contract reflects the market's collective assessment of the probability of that event occurring. A probability of 50% implies an even chance, while probabilities closer to 0% or 100% indicate a higher degree of certainty among traders.
The probability displayed is calculated as the total value invested in the 'Yes' shares divided by the total value invested in both 'Yes' and 'No' shares. A decrease in probability suggests that more capital is being allocated to 'No' shares, or capital is being withdrawn from 'Yes' shares, relative to the total market capitalization.
