Information Edge in Political Prediction Markets
Prediction markets consolidate data streams from opinion research, wagering platforms, and political operatives. Academic evidence demonstrates these instruments forecast electoral outcomes more reliably than traditional polling methodologies. Institutional participants monitor poll aggregations, by-election movements, and macroeconomic conditions to identify undervalued or overvalued contracts.
