The AI Forecasting Hackathon
85 builders had 32 hours to make an AI agent that could predict the future. Then we scored them for two weeks.
Each mark is one team, ranked left to right. Height is edge over the market — how much lower that team’s Brier score was than the market’s price on the same questions, across the two-week scoring window. Above the line is better than the market.
