Polymarket only -- Kalshi doesn't expose public trader data. This leaderboard draws from Polymarket's own public "Monthly" leaderboard (top 100 traders by profit over the last 30 days) -- not every Polymarket trader, and not an all-time ranking. Once we have that pool of 100 wallets, we independently score each one using their 90-day realized PnL history to compute Sirtio Score, which is a different window than the monthly pull used to find them.
Sirtio Score is built entirely from realized PnL -- average edge per position and total realized PnL magnitude, both damped by sample size -- read the full methodology. It needs more resolved history to validate -- read it as directional, not precise. Names are shown as-is from Polymarket; click a wallet address to copy it, a trader's name to view their Sirtio profile, or "View on Polymarket" to see their public Polymarket profile.
Every trader beyond this rank does not currently meet the minimum requirements for a Sirtio Score. This can happen for a few reasons -- no resolved positions in the last 90 days, or trading activity consistent with automated/bot behavior, which we filter out before scoring. They remain part of Polymarket's tracked pool and may appear here once they qualify.
