Understanding Prediction Markets:

Polymarket operates as a decentralized prediction market. The probability displayed represents the collective belief of market participants regarding the likelihood of a specific outcome. A probability of 41% for 'Over 213.5' points means that, based on current trading, the market assigns a 41% chance that the combined score of the Cavaliers and Pistons will be greater than 213.5.

Conversely, the probability of the 'Under 213.5' outcome would be approximately 59% (100% - 41%). Changes in probability are driven by the buying and selling of shares in each outcome. As more participants believe an outcome is likely, they will buy shares of that outcome, increasing its price and thus its implied probability. Conversely, if participants believe an outcome is less likely, they sell shares, decreasing its price and probability. This dynamic allows for real-time assessment of market sentiment and perceived likelihoods.
