Politics prediction markets
Elections, control, and policy outcomes.
Politics is the deepest, most-traded category in prediction markets — and the one where they most clearly beat traditional sportsbooks, which are barred from pricing most US elections. Contracts run from who controls Congress to whether a specific bill becomes law.
Because the same question often trades on several venues at once, politics is where comparing prices pays off most: a point or two of edge on a liquid election market compounds across a large position.
