How is this page computed?
Prediction.Markets computes consensus by volume-weighted aggregation across Kalshi, Polymarket, and Limitless. Outlier venues are flagged when their price deviates more than 2σ from the weighted mean. AI Oracle entries are independently sampled from 3 frontier models on a daily cadence. Full methodology →
