The Polymarket leaderboard ranks accounts on the global site by profit or by volume over the last day, week, month or all time, with each entry a pseudonymous wallet you can click into to see positions and trades. It's where the 2024 election whale became famous and where whale-tracking bots get their data. It's a good way to understand who moves markets; it's a poor way to pick trades, because profit rankings reward luck and size, volume rankings reward churn, and by the time a big position is visible the price has already moved.
What the columns mean
- Profit: realised P&L in the window. Big numbers come from big positions; a $10m bankroll with a 2% edge beats a $1k bankroll with a 20% edge.
- Volume: total traded. Market makers dominate; it's not a skill metric.
- Window: all-time rankings are dominated by a few 2024 election positions; weekly and monthly show who's active now.
How people use it
- Whale watching: following large wallets to see where size is going, especially on politics. Tools and bots automate this, which is why 'polymarket bot' is its own search term.
- Sentiment: if the top monthly accounts are all on one side of a market, that's information, though not necessarily an edge.
- Due diligence: checking whether a trader who's selling signals actually has the record they claim.
Why copying rarely works
- Survivorship. The leaderboard shows winners. The same strategy's losers aren't on it.
- Latency. Public positions show after fills. Prices adjust within seconds on liquid markets.
- Size. Whales move the price when they enter; you enter at the worse price they created.
- Inside information. Some outsized wins in 2025–26 turned out to be people with non-public knowledge of military operations or elections. Several were later charged. Copying them would have worked once and been unethical throughout.
Kalshi
Kalshi doesn't publish a comparable public leaderboard of individual accounts; its positions aren't public per user. That's a design choice toward a brokerage model rather than a social one.
