Accuracy Leaderboard

Everyone trades on prediction markets; almost nobody checks whether the prices are actually right. We do. For every market that has resolved, Predacle compares its last pre-resolution price against what really happened, then scores each platform on two things: sharpness (the Brier score — how confidently and correctly it priced outcomes) and calibration (when a platform says “60%”, does that happen about 60% of the time?). Lower Brier is better. Only platforms with at least 100 resolved binary markets appear; coverage grows as more resolution sources come online. Not financial advice.
