Polymarket Smart Money — Trader Skill Ranking

Polymarket Smart Money — Trader Skill Ranking What this gives an AI agent: a ranked list of Polymarket traders with difficulty-adjusted skill scores per category. Scores are derived from resolution-validated PnL on closed markets, not unrealized paper performance. Response shape (once skill-scorer warms up — Day 7+): - trader_address_hashed (k-anonymity preserved) - overall_skill_score (0-100), confidence_score (0-100) - category_breakdown: { politics, crypto, sports, macro, other } each carrying its own skill_score + sample_size - resolved_markets_count - wins_count, losses_count, win_rate - discovery_method Why difficulty-adjusted: predicting the favourite at 0.95 isn't skill — the calibration weights wins on close-to-50/50 markets higher than wins on lopsided ones. Score is comparable across categories only when paired with sample_size + confidence_score. Honest meta on Day 1: - coverage_level: experimental — skill-scorer is offline until Day 7. The endpoint serves the shape with an empty data[]. - warnings: ["data_collection_in_progress"] - metric_reliability: skill_score "not_available" until backfill. Pricing: $0.05 USDC.
