The Open Model Project

Open Source, Crowd-Powered Forecasting

We believe transparency and public collaboration will pave the way to better election forecasting.

So play with the inputs to our model to understand how it works, download the model for more options, follow us on Twitter, and join our discord server to discuss.

We'll never share your email with anyone else.
