ElectIndex is an election information and analysis platform covering U.S. politics and elections worldwide. Its central offering is coverage of the 2026 U.S. midterms, including forecasts for House, Senate, gubernatorial and state legislative races. Visitors can explore interactive maps, race pages, live polling averages, county-level data and analysis, with forecasts and core site content available free to read.

The platform also provides tools for examining election results and political data. The National Atlas brings together historical election information, precinct-level results, Census and American Community Survey data, religious adherence measures and presidential approval ratings. Users can view information across geographic boundaries and explore demographic patterns. Other features include an election simulator, map tools, replayable past contests and tracking of 2028 presidential polling; ElectIndex notes that its 2028 polling is not a forecast.

ElectIndex is funded by reader memberships and one-time donations rather than advertising or investors. Paid membership unlocks additional features, including Forecast+, the full simulator, the National Atlas and the ElectIndex Brief newsletter.
