How to Copytrade on Polymarket: The Basics

Pick the wallet carefully, then let the settings do the rest. Look for 30-60 days of consistent performance and moderate trade frequency, skip market makers and arbitrage bots, whose edge doesn't survive being copied. Keep slippage tight, mirror exits as well as entries, and review the wallet periodically rather than setting it and forgetting it.

Copytrading automatically repeats another trader's Polymarket positions in your own wallet. You choose a wallet to follow, connect a bot, and every qualifying trade gets mirrored using the position size and settings you've configured. You stay in control of your own wallet the entire time, the bot submits trades on your behalf, it never takes custody of your funds.

This guide covers the fundamentals of doing that well: how to tell a wallet worth following from one that only looks good, and how to configure a bot so execution doesn't quietly work against you. For a full click-by-click setup walkthrough, see how to copy trade on Polymarket.

Polymarket runs on Polygon, which means every trade is public on-chain the moment it happens. Anyone can look up a wallet's full trading history, there's no privileged access required. That transparency is what makes copytrading possible in the first place: instead of trying to out-analyze a market yourself, you can observe wallets that have already been consistently profitable and let a bot mirror their decisions.

Removing the need to react to news in real time also removes a lot of the emotional decision-making that trips up manual traders, chasing a market after it's already moved, or freezing during a fast one. The trade-off is that your results now depend entirely on the wallet you choose, which is what the next section is about.

A high win rate is the easiest thing to mistake for skill, and the least reliable one. Before following a wallet, look for:

Not every profitable wallet trades the same way. Some hold positions in long-running political or macro markets for weeks at a time. Others scalp fast-moving crypto or sports markets in minutes. Knowing which kind of trader you're following matters, because it determines how much your bot's execution speed actually affects your results.

Match your bot's speed to the trader's timeframe, not the other way around.

A wallet holding a position for weeks tolerates a few seconds of execution delay without it mattering much. A wallet scalping in and out of a market inside minutes does not, in that case, a slow bot or a slow monitoring setting can turn a winning trade you copied into a losing one by the time your fill lands.

Once you've picked a wallet, a handful of settings determine how closely your results actually track theirs:

• Sizing model — Fixed, exact, or proportional. Proportional (a percentage of your own balance) is usually the safest default when the trader's wallet is a different size than yours.
• Slippage tolerance — Keep it tight, around 2-3%. Loose slippage quietly eats into every fill, win or lose.
• Minimum liquidity — Skip markets under roughly $10,000 in liquidity. Thin books are where copied fills slip the most.
• Mirror exits, not just entries — A copytrade that copies the buy but not the sell isn't really following the trader's decision.

These rarely show up as a single bad trade. They show up slowly, as a gap between the wallet's reported performance and your own.

Copytrading automates execution, it doesn't remove the need to pay attention. Set aside a few minutes each week to check whether the wallet you're following has gone quiet, whether its performance has started to diverge from what drew you to it, and whether your own sizing and filters still make sense as your account balance changes.

The bot is the plumbing between the wallet you're following and your own. We use and recommend Kreo for this: it's non-custodial, so it can never withdraw your funds directly, and it finished first in our own hands-on execution speed testing.

This guide is deliberately focused on the fundamentals, wallet selection, settings, and the risks above, rather than click-by-click setup. For the full walkthrough of connecting a wallet, funding it, and creating your first copy trade task in Kreo, see how to copy trade on Polymarket.

Copytrading works because Polymarket's on-chain transparency lets you replicate a proven decision-maker instead of trying to out-guess the market yourself. It doesn't work automatically, the wallet you pick, the settings you tune, and the attention you keep paying after setup all still matter.
