◆ Methodology

Stats in this report are a frozen snapshot taken on May 20, 2026. The live wallet profile reflects current numbers — they will diverge over time.

Win rate is computed on resolved Polymarket bets only. P&L uses on-chain entry costs vs resolution outcomes from market_outcomes. Win-rate alone is not a finding; we look at the difference between scope win-rate and the wallet's global rate (edge), combined with p-value vs a null model and signed P&L.

Funding clusters are detected by USDC lineage traced through Polygonscan. Time clusters are wallets that placed sized bets on the same condition within a 60-minute window. Cluster membership is a signal, not an accusation — read the full methodology for caveats.

Sources: Polygon on-chain (Subsquid indexer), Polymarket Gamma API for market metadata, Polygonscan for USDC funding traces.
