AI Now Matches Prediction Markets in Forecasting Real Events, Study Finds

In brief Prophet Arena tests AI models by having them predict real-world, unresolved events, with GPT-5 currently leading the rankings. AI models show distinct prediction “personalities” and often diverge from market consensus, sometimes generating high returns. Early results suggest AI can forecast as accurately as prediction markets, potentially transforming institutional decision-making. A new artificial intelligence…
