This market aggregates the views of many independent traders, each risking real capital on their forecast, which can reveal information sportsbooks have not yet priced in. Over time, prediction market odds tend to converge toward actual outcomes, making them a useful benchmark for comparing against traditional betting lines and assessing market efficiency.
