Coverage by feature
Trader rankings & wallet analyticsPolymarketGlobal leaderboard, profiles, positions, trades and reported wallet history.
Cohorts & fundingPolymarketGrouped wallet positioning and observed funding sources; records depend on the available dataset.
Market discoveryVenue-specificPolymarket, Kalshi and Hyperliquid use separate endpoint families and may expose different units and fields.
Matched marketsPolymarket ↔ KalshiMatched contracts and confidence scores. A match does not guarantee equivalent settlement terms.

Keep units visible
- The global leaderboard winRate is 0–1; profile winRatePct is already a percentage.
- P&L and portfolio values are USD unless the endpoint specifies otherwise. Kalshi volumes may represent contracts.
- A price change from 0.60 to 0.65 is five percentage points, not a five-percent relative return.
- Keep null distinct from zero. Do not fill a missing time-series observation with an invented data point.
A response is not always the whole record
Show snapshot timestamps and the returned historical window. Paginate positions and trades before presenting totals as complete. Advanced metrics can describe an older or different period from the overall leaderboard P&L; its latest snapshot timestamp does not establish freshness for every field. Risk measures depend on the available P&L history and are not cash-flow-adjusted returns.
