What is Polyrank?
The skill-analytics layer for Polymarket — who is genuinely good, not just lucky.
Polyrank ranks ~2.8M Polymarket wallets by genuine forecasting skill — calibration (Brier score), alpha-vs-mid, information coefficient, and risk-adjusted return — not vanity P&L or win rate. A 99%-win-rate trader can be a coin-flipper riding small edges; an 18%-win-rate trader can be printing money on long-shots. Polyrank's thesis: copy the skilled, not the lucky.
Every number traces to a public Polygon transaction. Polyrank is read-only, non-custodial, and not affiliated with Polymarket.
