PredictionToolkitWhat is Election Betting Odds?
Inspect candidate ranges and recorded amounts bet rather than treating a summary as executable at every size. Recent changes cover four hours, a day and a week; longer race charts and historical methodology/track-record sections add context.
Nomination and election-winner contracts answer different questions, as do a state race and chamber control. The site states one-minute updates for headlines but 20-minute updates for state odds. Check the map's own update time.
