BehaviorBench (Behavioral Traces) - Trade Direction (DirectGen): leaderboard
BehaviorBench (Yang et al., 2026) tests whether a model can predict what a real pseudonymous user will do, using 2,000 wallets reconstructed from public prediction-market and on-chain records with chronologically held-out targets. The model sees the recent raw history of the wallet (DirectGen). The board is the accuracy in percent of predicting whether the next transaction of the user is a buy or a sell; chance is 50 and higher is better.
Metric: Direction accuracy (%): predicted BUY or SELL of the next transaction; history interface DirectGen (the target wallet's most recent visible history, up to 30 events for Belief); 2,000 pseudonymous prediction-market wallets reconstructed from public Polymarket metadata and Polygon on-chain logs, about 59,560 chronologically held-out test transactions; unparsable outputs count as failures; chance 50, context-only baseline 52.85; higher is better.
