How to learn from Polymarket smart money
A profitable wallet is only useful if you can tell why it made money and whether that will last. These are the questions to ask of a trader’s record, and where PMWallets answers each one.
Start from a record that cannot be edited
Most leaderboards recompute all-time figures every time you look, so one lucky month keeps a trader near the top long after it stopped meaning anything. PMWallets scores a stated block window from the Polygon ledger, and a published run is never rewritten. The record you study was written before you looked at it, not reconstructed after.
Study the trader, not the address
A Polymarket trader usually signs with one address and holds positions through a proxy, and some spread their trading over several. Ranked separately, each looks like half a trader. PMWallets clusters addresses that demonstrably trade as one into an entity, so the behaviour you study is the whole of someone’s trading.
Read the win rate by its lower bound
Three wins out of three is 100% and means almost nothing. Every entity’s win rate comes with a 95% confidence interval and the number of decided markets behind it, and the board filters on the lower bound. A trader whose interval stays above 60% across hundreds of markets is telling you something; one at 100% over five markets is not yet.
Check whether one market made the whole record
Realised profit can be a single lucky resolution. Take away the most profitable market and see what is left. PMWallets prices its address unlocks on exactly that figure: a wallet that made nothing without its best market is free to unlock, because there is little to learn from it.
Maker or taker: how the edge is earned
Each entity is tagged maker, taker or two-sided from the share of its traded value in each role. A maker earns by quoting prices that others trade against, which takes patience and carries inventory risk. A taker earns by being right about direction or timing, and pays to act now. They are different skills, and copying a maker’s fills by taking liquidity is a different trade.
Find where the edge lives
Filter the board by category — crypto Up or Down, crypto, sports, esports, politics, economy, geopolitics, science and tech, culture — and open an entity to see the markets behind its figures. A specialist who stays inside one category is easier to learn from than a generalist whose profit is spread thin.
Look at their fill sizes and how often they trade
The entity page shows median fill size, fills per day, active days, total bought and fees paid, and each fill with its market, side, price, size and role. Fill size relative to price shows conviction: buying heavily at 0.95 is a very different bet from buying at 0.20.
Ask whether the edge is still alive
Every entity is marked active (filled in the last 24 hours), quiet (no fill for one to seven days) or dormant (nothing for over a week), with the date of its first fill. A strong record from someone who stopped trading a month ago is history, not a live edge.
Watch them trade as it happens
Subscribe to an entity and each of its fills is pushed to you over WebSocket or a signed webhook, typically within a second of the block, carrying block, detection and push timestamps. Seeing what a trader does at the moment they do it, and what the market does next, teaches more than reading a summary afterwards.
What a record cannot teach you
A window is a sample, and some good records are luck. Some traders know things you do not. By the time you see a fill the price may already have moved, so copying it is not the same trade. PMWallets provides data about what traders did; it is not advice about what you should do.
