Based on the top 50 Polymarket traders of the month, checked on 10 October 2026, and on Polymarket’s own profit data.
The short answer
A profit on a Polymarket profile or leaderboard is a number before fees, and it says nothing about how much the trader had to trade to make it. Before you trust a wallet, look at four things: the profit after fees, the profit against the money traded, how instant the trades were, and how many bets made the month.

1. Profit after fees
The profit or loss on a Polymarket profile does not take out the fees (we checked 15 wallets). For most leaders the gap is small; for some it is not.
| Trader | Polymarket shows | Fees | After fees |
|---|---|---|---|
| theowalcott | +$97,276 | $25,513 | +$71,764 |
| googleplay | +$93,703 | $15,024 | +$78,679 |
| joseph00677 | +$388,935 | $52,189 | +$336,746 |
| totoro3miyazaki | +$1,203,582 | $113,619 | +$1,089,964 |
30 days to 10 October 2026. Of the 35 leaders with full history and a profit, the fees took more than 10% of the profit for 4. Polymarket also paid part of the fees back to some of them; that money is not in either figure. The whole table: Polymarket’s top 50 traders and their fees.
2. Profit against the money traded
A big profit can come from a huge amount of trading. The leaderboard shows both numbers; divide one by the other. For the typical leader with full history, the month’s profit was about 12% of the money traded. For theowalcott it was 2.8% ($97,276 on $3.4 million traded), and for joseph00677 3.9% ($388,935 on $9.9 million). A thin profit per dollar traded leaves little room for fees and for a worse month.
3. How instant the trades were
A trader who mostly uses limit orders that wait for their price pays almost no fee and can get a share of other traders’ fees. If you copy such a trader by buying at the screen price, you pay the fee they did not. Among the leaders, BreakTheBank put about 19% of the money in with instant trades and paid $4,936 in fees on $40.6 million traded; joseph00677 put about 87% in instantly and paid $52,189 on $9.9 million. Our check shows the fees of any wallet; the limit order traders page shows what this style costs across 27 wallets.
4. How many bets made the month
A month made by two or three large wins is a different thing from a month made by hundreds of small ones. The first can be one lucky week. The profile and the leaderboard do not show this; the list of finished bets does. Our full report breaks a wallet’s month down bet by bet.
A short checklist
- Profit after fees, not the profile figure.
- Profit as a share of the money traded.
- Share of instant trades: copying a patient trader with instant buys costs fees they never paid.
- Number of bets behind the profit, and whether one or two bets made it.
We don’t tell anyone whom to follow or what to bet. These are the numbers to look at before you decide for yourself.
Questions
Is the Polymarket leaderboard profit before or after fees?
The profit on a Polymarket profile is before fees: we checked 15 wallets against Polymarket’s own profit data, and 14 matched the figure before fees. Subtract the fees paid in the same period to get the profit after fees.
How do I check a Polymarket wallet’s fees?
Type the @name or paste the address into the free check above. It shows the fees for the last 30 days to the cent, what Polymarket shows for the month, and the month after fees.
Why does copying a profitable wallet not give the same result?
One reason is the fee. If the wallet waits for its price with limit orders and you buy instantly at the screen price, you pay a fee it did not pay, and the price may have moved since its trade.
