Polymarket Copy Trading: The Complete Guide

The idea: mirroring another trader's bets

Copy trading means automatically reproducing another trader's positions. On Polymarket it is especially simple: every account is a public wallet on the Polygon blockchain, so anyone can see what a trader buys, at what price and when.

A copy-trading tool does three things:

1. It watches the trader's wallet, around the clock.
2. It detects every buy and sell, usually within seconds.
3. It mirrors the trade in your own account, with the stake you chose.

You keep control of your money and your positions: you can stop copying, sell or withdraw at any time.

What you really copy… and what you don't

A trader makes money with three levers. Only the first one copies well:

• Their picks: which market, which side, at what price. This is what a copier gets.
• Their sizing: they bet big when confident, small otherwise. With a fixed stake, a copier doesn't reproduce this.
• Their speed and place in the order book: a bot that buys in a split second, or posts orders that others fill, earns on spreads that a copier arriving later can't capture.

That is why a very profitable trader is not necessarily a good trader to copy. The clearest example is RN1, an account that made over $10 million while its copiers lost money.

What it costs

Three costs add up on every copied bet (details in our fees guide):

• Polymarket fees, paid by whoever takes an existing order: zero on many markets, up to about 5% × (1 − price) on sports markets.
• The copy tool's fee: 2% of the amount on PolyCopy.
• Slippage: the copier buys right after the trader, often slightly higher, from 0 to a few percent.

Example: a copied bet at 0.50 on a sports market costs about 2.5% (Polymarket) + 2% (bot) + 1% (slippage), so 5 to 6% in total. A copyable trader must earn clearly more than that per bet.

Why most copiers lose

In June 2026 we measured the real results of copiers on PolyCopy: about 95% of them ended up losing. Not because copy trading doesn't work, but for three very concrete reasons:

• they copied ultra-fast bots whose margin (1 to 3% per bet) was lower than the copier's costs;
• they followed traders spotted on one good month, who lost in the other months;
• their stakes were badly sized: the whole bankroll went on the first game of the day.

Since then, we check every trader over 12 months before recommending them. The full method is in Which Polymarket traders to copy?

The 6 criteria of a copyable trader

1. Their picks win at equal stakes, not only thanks to a few huge bets.
2. They bet before the event, not during it: the copier then gets almost the same price.
3. The price doesn't jump right after they buy.
4. Their profits don't rely on two or three lucky shots.
5. They are consistent: several bets a week, every week.
6. It holds over 12 months, quarter after quarter.

How much to start with

It depends on the trader's pace. A simple rule: bets per week × stake × average holding time. A trader who bets 20 times a week and holds positions for two days keeps about 6 bets open at once: with $5 per bet, plan at least $50 to $100 so you don't miss bets for lack of funds.

Mind Polymarket's minimum: an order must cover at least 5 shares (about $2.50 at a price of 0.50), so a $2 stake is often rejected. To fund your wallet, follow our deposit guide.
