Who is actually winning.
Profit and volume are two different leaderboards, and the gap between them is the whole story. Big volume with small profit is a market maker or a gambler. Big profit with small volume is edge.
You versus the whales.
Connect the EVM wallet you trade Polymarket with, read-only, and WhaleWatch pulls your portfolio value and lifetime profit from Polymarket's own public API, then places you against the top 50.
Cumulative profit, daily, as Polymarket's accounting reports it. Open positions are marked to market.
Three shapes of whale.
The edge
High on profit, absent from volume. Few trades, usually in one niche. These are the accounts worth studying, and they are rarely famous.
The market maker
Top of volume, flat on profit. They earn the spread thousands of times. Copying them is pointless: their edge is speed and inventory, not opinion.
The hot hand
Top of profit today, nowhere on the month. One big call that landed. Check the longer windows before you call anyone a genius.
Why profit here is trustworthy
Polymarket's leaderboard is settled against market resolution, not self-reported. It still only shows realised and marked positions, so an account deep in an open bet can look richer or poorer than it is.
Mind the window
"All time" rewards accounts that were early and large. "Week" rewards whoever got one market right. The month is usually the fairest single view.
