Understanding Prediction Markets

Polymarket operates as a decentralized prediction market where users trade shares in the outcome of future events. The probability displayed for an outcome (e.g., Raul Brancaccio winning) represents the aggregate belief of market participants, reflected by the current trading price of shares for that outcome. A probability of 0.05% suggests that, based on current market sentiment, the likelihood of Raul Brancaccio winning is assessed as very low. Price movements reflect the consensus view adjusting to new information or changing expectations. The probability is calculated as (Number of shares in the winning outcome) / (Total number of shares).
