Most & Least Accurate Forecaster Organizations

How the ranking works

Each forecaster's sourced accuracy is the share of their score-eligible outcomes that came true. TRUE or FALSE assessments count only with a structured evidence link and consistent recorded timing. Rankings use the Wilson score interval (95% confidence), not raw accuracy, so a single lucky result cannot outrank a larger documented record. Leader and laggard groups are disjoint, so one actor is never presented in both. Methodology →
