How to Rank Polymarket Traders by Skill Instead of Profit
Profit ranks bankrolls and win rate ranks price preferences. To rank Polymarket traders by skill, score calibration, edge over the price paid and risk, then check the sample size.
Why profit and win rate rank the wrong thing
| Ranking key | What ends up on top | What it misses |
|---|---|---|
| Profit | The largest bankrolls, and one-off concentrated bets | Whether the result would repeat |
| Win rate | Wallets that buy high-priced favourites | The price paid for each win |
| Volume | Market makers and bots | Everything about judgment |
| Skill score | Wallets whose picks beat the prices they paid, with risk counted | Needs a long enough record |
The measurements a skill ranking uses
- Calibration. When a trader's entry prices imply 70%, do those outcomes happen about 70% of the time? It is scored against the market's own prices, so the bar is beating the market, not beating a coin flip. See What's a good Brier score?.
- Edge over the price paid. How much more often the side they bought won than the price they paid for it implied.
- Risk-adjusted return. A result reached while routinely risking ruin ranks below a steadier one.
- Sample size. Every figure is shown with the number of resolved positions behind it.
Where to see it
The Polymarket leaderboard shows the default skill ranking and several other boards, and prints the weights and gates that produced the order under the table. A free account opens the top 100 of every board with the activity and category filters; sorting by any single metric, time windows and building a ranking of your own are part of the paid plans listed on the pricing page. How it works explains the scoring.
A ranking describes past records. It is not a prediction of who will win next.
Questions
How do you rank Polymarket traders by skill instead of profit?
Score each wallet on calibration (whether outcomes happened as often as its entry prices implied), on its edge over the price it paid, and on risk-adjusted return, each with the number of resolved positions behind it. Use profit only as a gate so that unprofitable wallets do not top the list.
Why not rank Polymarket traders by profit?
Profit grows with bankroll, so a profit ranking is mostly a list of who traded the most money, and a single concentrated bet can put a wallet on top without any repeatable judgment behind it.
Can I build my own Polymarket trader ranking?
Yes. Polyrank's Ranking Builder lets you weight metrics and set filters to produce your own ranking. It is part of the paid plans; the default skill ranking and its recipe are public.
