Other trackers rank wallets by the profit the whale made. We rank them by the profit you would have kept — simulated against the real orderbook, three seconds behind. Every wallet screened for wash trading before it reaches the board.

Every tracker ranks whales by raw PnL. But by the time you see their trade and place yours — call it 3 seconds — the price moved and the book thinned. You do not get their fill. You get a worse one, and nobody tells you how much worse.
Buy both outcomes of the same market in mirrored size, book the winner, bury the loser. Your public record shows a hot streak. Copy that wallet and you are copying a magic trick.
Four steps, running continuously on our own infrastructure.
When a whale trades, we snapshot the live orderbook at that exact moment. Polymarket does not archive this. It cannot be backfilled later — which is precisely why it is worth capturing 24/7.
We walk that stored book as if you placed a $250 order 3 seconds behind them, paying real slippage against real depth. Four latency tiers, three size tiers, every trade.
Copyability ratio = your simulated ROI ÷ the whale's ROI. 1.00× means you keep all of their edge. 0.7–0.9× is typical. Below zero means the edge evaporates the moment you try to follow it.
Four wash signals — self-opposite, round-trip, padding, statistical anomaly — rescanned every 30 minutes. Blacklisted wallets never reach the leaderboard at all.
Our window starts 2026-07-08, so every stat reflects what we have observed — not lifetime performance. Wallets under 30 trades carry a LOW N flag because the numbers are noisy at that sample size. Wash detection is probabilistic, which is why we publish suspect and grey tiers instead of a fake binary. None of this is financial advice, and a good copyability ratio is not a promise of profit.
