About

Mission

Election Odds Aggregator aims to provide the comprehensive and up-to-date view of the 2024 US Presidential election odds. We aggregate data from 3 major prediction markets: PredictIt, Smarkets, and Polymarket, updating our data every 5 minutes to ensure you have the latest information.

In addition to the aggregate predictions for each electoral event, Elections Odd Aggregator also shows the time series of each individual market's predictions, as well as information on the spreads and the disparity across markets (the range of prices, or probabilities, of each event). Unlike other election betting odds aggregation sites, this provides a clearer picture of how much variability there is across betting markets.

Data

We currently track the odds of events across 3 prediction markets. Our data begins in mid-July 2024. Unlike other sites, our raw data is available for download (note that early data may have some interruptions):

The market correlation table is created by calculating the correlations in prices over 5 minute intervals for each market, per outcome (e.g. a particular candidate winning). Then these are correlations averaged across outcomes, weighting by the most recent event probabilities.

Accuracy and Limitations

While Election Odds Aggregator aims to be as accurate as possible, there can be errors. These odds are for entertainment purposes only.

We recommend using our data as one of many tools in understanding the election landscape, not as a definitive prediction.
