How this leaderboard is ranked
Rivo ranks traders by profit on the bets they placed over the past 7 days. Each bet counts when its market settles, against the price the trader paid, so a bet that is still open adds nothing yet. A trader needs 5 settled bets to be listed, and win rate and return use the same bar. Every number comes from trades Rivo recorded on Polymarket and Kalshi.
