Understanding Prediction Markets

Prediction markets, such as Polymarket, function as decentralized platforms where users can bet on the outcome of future events. The price of a contract on a platform like Polymarket represents the market's collective belief in the probability of that event occurring. A price of $0.99, for instance, suggests a 99% probability that the event will occur, while a price of $0.50 indicates a 50% probability. Probabilities on Polymarket are denominated in "shares" where 1 share equals $1.00.

In this specific market, a probability of 99.95% suggests a very high degree of consensus among participants regarding the specified outcome. The sudden 55.45% delta indicates a rapid recalibration of this consensus within the last hour.
