Are Polymarket Copy Trading Bots Safe? (2026 Guide)

Some are, some aren't, the dividing line is custody. Bots built on non-custodial wallet infrastructure can trade for you without ever being able to withdraw your funds. Bots whose teams hold user private keys directly are a different story: of the five copy trading bots we tested, both of the confirmed exploits happened on team-held-key bots.

Most Polymarket bots run inside Telegram. They need the ability to place trades with your money. That's an unavoidable amount of trust, and it's why "is this bot safe?" is the right first question, ahead of speed, features or fees.

We've put five Polymarket copy trading bots through hands-on testing for our copy trading bots guide placing real-money trades and researching each bot's wallet infrastructure and incident history. This article collects everything we learned about the safety side specifically: how these bots hold funds, which ones have already been exploited, and how to vet one yourself before depositing anything.

Every copy trading bot needs signing authority — a way to place trades from a wallet you fund. The safety question is never whether a bot has that authority, but how it gets it. There are two models in this market, and the difference between them accounts for almost the entire spread in our security scores.

Polycop does use Gnosis Safe, but the wallet is still created and controlled by the team rather than by the user. Because the team generates and retains the private keys, users must ultimately trust the operator not to misuse or lose access to those keys. This custody model introduces a level of trust that isn't present with fully non-custodial setups, which is why Polycop scores lower on security despite having no reported exploit of its own.

This isn't a theoretical risk. Two of the five copy trading bots we tested have confirmed exploits, and both hold user private keys themselves.

Worth stating clearly: we have no exploit reports for Kreo, Polycool or Polycop. But only the first two of those pair that clean record with infrastructure that would limit the damage if something did go wrong.

Here's how every copy trading bot we've tested scores on security, alongside the custody facts behind each number.

Bot	Security	Custody	Reported Exploits
Kreo	9/10	Non-custodialPrivy + Gnosis Safe	None reported
Polycool	9/10	Non-custodialPrivy	None reported
Polycop	2/10	Team-held keysGnosis Safe (team-controlled)	None reported
Polygun	0/10	Team-held keysNo third-party infrastructure	~$70,000 exploit
Polycule	0/10	Team-held keysNo third-party infrastructure	~$230,000 exploit

Security scores reflect our own research and hands-on testing. Betmoar isn't listed because it's a manual trading terminal, not a copy trading bot.

Five checks, in the order we'd run them. If a bot fails the first one, the rest barely matter.

1. 1

   Check who holds the keys

   This is the single biggest safety question. Look through the bot's documentation for third-party wallet infrastructure like Privy or Gnosis Safe that setup means the bot can execute trades without ever being able to withdraw your funds. If the team generates and holds the wallet itself, everything you deposit depends on that team's honesty and their security practices.
2. 2

   Search its exploit history

   Search the bot's name alongside words like "exploit" or "hack" before depositing anything. Two of the bots we tested Polygun and Polycule have confirmed exploits, and Polycule hasn't upgraded its wallet security since losing roughly $230,000 of user funds. A past incident with no infrastructure change afterwards is the clearest red flag there is.
3. 3

   Verify you're using the official bot

   Copycat bots imitating real ones are a genuine risk on Telegram. Always reach the bot through its official website or documentation rather than a search inside Telegram, and confirm the handle matches the one those official channels reference.
4. 4

   Look at the security features on offer

   Check whether the bot offers protections like two-factor authentication, and whether it publishes anything about how funds are secured. None of the bots we tested currently has a published security audit. Even our top-rated pick, Kreo, loses a point for not yet offering 2FA so treat any bot's security claims as unverified until its infrastructure says otherwise.
5. 5

   Start smaller than you think you need to

   Whichever bot you choose, your first deposit should be a test, not a commitment. Place a small copied trade, withdraw once, and confirm the full cycle works before scaling up to a stake you'd actually mind losing.

Beyond that, deposit only what you're genuinely comfortable putting at risk, and confirm current fees directly with the bot before you start. And before following anyone, our guide to finding a wallet worth copying covers how to tell a genuinely profitable trader from a lucky streak.

So, are Polymarket bots safe? The honest answer is that the market splits cleanly in two. Non-custodial bots like Kreo and Polycool have the infrastructure to be trusted with a trading wallet.

Team-held-key bots ask for trust which they haven't earned. Roughly $300,000 in reported exploit losses, all of it on team-held-key bots, is the clearest signal this market has produced.
