These charts display normalised implied probabilities derived from prices on the Betfair Exchange. For each timestamp, the last traded price is converted using the standard formula (implied probability = 1 ÷ price) and then normalised so all selections sum to 100%.
Data are sourced from exchange market prices and updated periodically. To maintain clarity, selections that never exceed a minimum threshold may be omitted. Market prices aggregate trader positions and available liquidity. They respond to news, sentiment and positioning, and should be understood as a visualisation of market expectations rather than votes cast or official forecasts.
Markets may suspend or settle in accordance with exchange rules at procedural milestones. Final outcomes are determined by the exchange.
