Trader data and intelligence
Professional-grade trader data, built from the blockchain up
Polymarket publishes every trade and almost none of the meaning. We rebuilt the whole venue from the chain up, so you can tell at a glance what kind of trader you are looking at, where they actually win, and whether any of it is worth following.

What we hold
Six things we know about every trader
Enough to tell them apart at a glance, and enough to dig into when you want to.
Who they are
Trader type
Directional trader, market maker, arbitrage, or machine speed. Named, not guessed at.
Why it matters. Some edges cannot transfer to anyone following them. This is the first thing worth knowing.
Where they win
Category record
Ranked in 47 slices: category, kind of bet, entry price, stake size.
Why it matters. Almost nobody is good at everything. Overall rank hides which part they are good at.
What they made
Track record
Profit split by how it was earned, return on money actually deposited, win rate, profit factor.
Why it matters. Return on deposits is the honest version. Return on volume flatters anyone who trades a lot.
How rough the ride is
Risk profile
Worst drawdown, daily swing, share of weeks in profit, current streak, best and worst day.
Why it matters. Two traders can finish level and be nothing alike on the way there.
How they trade
Behaviour
Hold time, how positions end, sizing consistency, hedging, and pre-match against in-play.
Why it matters. Tells you what following them would actually feel like, day to day.
Is it worth it
Copy Score
Whether following them has historically left anything after what copying costs.
Why it matters. Free on every trader. Built to rule people out rather than to rank them.

Why it matters

Copy the right people, not the loudest ones
Good trader data is what separates a real edge from a big bankroll, and shows you which markets to follow someone into.

Copy Score
Is any of it worth following?
Copying isn't free — you buy after they do, and there are fees. Copy Score is what was left on their finished trades after that. The cost is much the same whoever you copy; what changes is whether their edge clears it.
Great traders aren't always great to copy. Copy Score tells you which ones are.
| You see | What it means |
|---|---|
| Proven | Copying them has worked on their finished trades. |
| Ahead | They finish ahead of what copying costs — but only just. |
| Caution | They make money. It doesn't survive being copied. |
| Losing | They've been losing on their own trades, before copying costs even start. |
| Not comparable | They close out early, so we can warn about them but never rank them alongside hold-to-the-end traders. |
| Thin history | Too few finished trades to stand behind. A big return either way can still be one bet that came in. |
| Not scored | The classifier has not graded this wallet. That is not a middling score; it is the absence of one. |
Free on every trader, and not one of the things we rank people by. It works to rule traders out, not as a shortlist to work down. Read the Copy Score explainer or see how it has performed.

Under the hood
Why this is hard, and why ours is different
Everything on Polymarket is public, so people assume the hard part is done. It is not.
The chain records fills, not positions
Every buy has to be matched to whatever closed it before a wallet has a cost basis or a real result.
Money moves without a trade
Transfers, merges, late claims and venue rewards all shift a balance without anyone predicting anything.
A trade means nothing without its market
Polymarket does not publish a consistent category or bet type, so we work it out for every market ourselves.
What most sources do not do
Every market sorted
99.99% of 2,598,463 markets carry a category and a kind of bet.
Tied to real events
1,639,007 markets matched to the fixture behind them, so pre-match and in-play are separable.
Venue rewards split out
Rebates and liquidity rewards are held apart from money won by trading.
Ranked within a market
Not one leaderboard position, but a standing in each category a trader has traded.

How we know it is right
Checked against Polymarket's own numbers
If we come out higher than the venue does, the trader is not published at any margin. Understating is the safe direction to be wrong in.
One answer, read everywhere
Classification is worked out once and stored, so no two screens can show different verdicts about the same trader.
Thin evidence shows as thin evidence
Where there is not enough finished history, the page shows nothing rather than a number that looks like discipline.
No gaps in the history
Every day since September 2020 is indexed, 2,179 of them without a break.
Three counts, three different things
Seen
3,052,840
Wallets with on-chain activity we can read. Most have traded a handful of times and there is nothing meaningful to measure.
Tracked
4,373
Wallets that trade enough to compute a full record for, across every indicator on this page.
Published
3,687
Tracked wallets whose numbers reconcile against Polymarket's own. The rest are held back until they do.
Seeing a wallet and having a record worth publishing about it are three steps apart. Warehouse counts as of 20 August 2026, and the last two move as new wallets are computed and reconciled.
Limits
What this data does not do
- A record of what has already happened, not a forecast.
- A wallet is not always one person, and one person is not always one wallet.
- No score is not a bad score. It means we will not claim something we cannot stand behind.
- We do not rank traders by Copy Score, and we do not publish a list of traders to copy.
- Your fills will differ from theirs. You buy after they do, at whatever price is there then.
FAQ
Questions about our trader data
Where does Polycopy's Polymarket trader data come from?
Polycopy's trader data comes from the Polygon blockchain itself, rebuilt into 1,637,015,470 individual trades. Polymarket runs on a public chain, so every trade, transfer and settlement is recorded permanently. What the chain does not provide is meaning: it records that an address bought shares at a price, not what that address now holds, what it paid on average, or whether the market was an NBA game or an election. We read those raw records, match every purchase to whatever closed it, attach the market and the event each trade was about, and roll the result up per trader. We also use Polymarket's own public market data and live sports schedules to know what each market was and when it started. Nothing here comes from a leaderboard someone else computed, which is why we can measure things a leaderboard cannot show. Figures as of 20 August 2026.
Why is measuring a Polymarket trader harder than it looks?
Measuring a Polymarket trader is hard because a wallet's balance changing is not the same thing as that trader doing well. Value moves in and out of a Polymarket wallet for reasons that have nothing to do with predicting anything: shares arrive by transfer, positions get split and merged, winnings are claimed weeks after a market settles, and the venue pays some traders rewards simply for providing liquidity. Any of those can make a wallet look profitable without a single good call. On top of that, a trade means very little without knowing what the market was about and when it started, and Polymarket does not publish that consistently. Separating genuine trading results from everything else, then attaching each trade to the market and event behind it, is most of the work. It is also why two sites can quote different profit figures for the same wallet.
How is this different from the Polymarket leaderboard?
A leaderboard ranks traders by profit, which answers who won rather than who is good. The largest profit on any board usually belongs to whoever moved the most money, and it says nothing about whether that result came from judgement, from scale, or from a strategy that only works for the person running it. It also treats a trader as a single number, when most traders are strong in one or two market types and unremarkable everywhere else. Because we attach a category and a bet type to every market, we can rank a trader inside each one: 47 separate slices per trader, over their full history and over the last 30 days. That turns a leaderboard position into something more useful, which is what a trader actually has a record in, and where they have none.
What is the trader classification system?
Polycopy's trader classification has two separate layers, and we keep them apart on purpose. The first is descriptive and carries no judgement: how a trader exits positions, how consistently they size, how many categories they trade, how long they have been active, and whether their results are rising, steady or cooling. None of that makes a trader good or bad, it just tells you what following them would be like. The second layer is a caution. Some traders earn in ways that do not survive being mirrored, such as market makers who collect the spread you would be paying. We flag those types so a low score has an explanation attached. A flag is not a verdict, and the absence of one is not an all clear, it only means we have not identified that wallet as one of those types.
How current is the trader data?
Prices update continuously, and the rest of the trader data refreshes on a schedule through the day. Market results are checked and applied within minutes of a market settling, so a page does not sit showing an open position in something that already finished. Trader results and category records refresh hourly. The slower-moving parts, meaning behavioural patterns, rankings and classification, are rebuilt daily, because those describe habits rather than events and recomputing them more often would make them flicker without telling you anything new. Every figure carries the date it was computed, and where a number is stale we would rather show its age than quietly present it as current. The underlying history runs continuously from September 2020, which is 2,179 days without a gap, so a trader who was active three years ago is measured on the same basis as one who started last month. New markets are sorted into a category as soon as they appear rather than waiting for the next daily pass.
