Information Edge in Political Prediction Markets
These markets synthesise intelligence from opinion surveys, wagering data, and Westminster insiders. Academic evidence demonstrates they forecast election outcomes more reliably than traditional polling methodologies. Skilled participants monitor polling trends, by-election swings, and macroeconomic conditions to identify undervalued or overvalued political positions.
