Methodology after the signal

How the projections are built.

Every projection is built from public polls, an open Bayesian method, and the source data behind it — all on the page.

  • Most of our projections aggregate public polls in a Bayesian BSTS model — house effects measured and corrected, accuracy calibrated on past elections. Simulation only translates it all into seats.
  • Prediction-market data (Polymarket) sits beside the model as a disagreement detector, not a substitute.
  • Riding and constituency probabilities are conditioned on national and regional swings, then re-aggregated to seat distributions.
  • Source data, methodology notes, and model outputs are public at each desk. Updated on a rolling basis as new polls arrive.
