What are prediction markets?
Prediction markets let participants buy and sell shares in the YES or NO outcome of future events. Aggregated trading produces a price between $0 and $1 that reflects the crowd's estimated probability. OutbreakWatch aggregates publicly available data from Polymarket and Kalshi. We do not facilitate trading, and these probabilities are not investment advice.
