Search for the best Polymarket copy trading bot and you get dozens of Telegram bots, web terminals and GitHub repos, plus a lot of affiliate pages that repeat each other's claims. This comparison covers the tools people ask about most, checked against each product's own site or docs where we could reach them, as of 26 September 2026. Where a detail isn't published, we say so. PolyZig is one of the products compared, and it's ours, so weigh that section accordingly.

How a Polymarket copy bot works

Every Polymarket trade settles on Polygon, so every wallet's activity is public. A copy bot watches the wallets you pick, detects a new trade, and places a matching order for you at the size you set. The real differences between products come down to four things: where your private key lives, how fast a trade is detected, what you pay on each fill, and which controls stop a copied trade from doing something you wouldn't.

Detection is the part people underestimate. A bot can poll Polymarket's API, wait for the trade to confirm in a block, or watch pending transactions in the mempool. Each earlier step costs more to run and gets you closer to the price the trader you follow got. You never get their exact price: you enter after them, you may pay fees they don't, and a large trader can move the market before your order lands.

The bots and platforms compared

Kreo (KreoPoly)

Interface: a Telegram bot first, plus a web app, with a browser extension listed as coming soon (Kreo docs). It trades both Polymarket and Kalshi.
Custody: wallets are held through Privy, which Kreo says keeps them "away from the trading layer in secured air-tight enclaves" (security). You can export the private key through Kreo Hub; there is no seed phrase (export keys).
Fees: a fee of max(0.003, 0.07 × price × (1 − price)) per share, lowest at extreme odds and highest at 50/50, where the docs list about 0.0175 per share. It applies to buys, sells and redeems, with 0.3% on redeems and claims (fees). Volume-based cashback returns 5–25% of your own fees (cashback). The fee page mentions no subscription.
Notable: five sizing modes, including portfolio-weighted and balance-weighted (buy modes); percentage, fixed, trailing and layered stop-loss and take-profit; an auto-hedge option (advanced).
Strong at: the widest set of copy controls on this list, and Kalshi support.

PolyCop

Not to be confused with polycopy.app or with PolyZig's old name (see below).

Interface: Telegram only, via @PolyCop_BOT (PolyCop site).
Custody: the site says your key is generated inside your Telegram session, is "never sent to a server", and can be exported to MetaMask (PolyCop site). That is the site's claim; we couldn't verify it independently.
Fees: 0.5% when a trade fills, gas covered, no subscription, and no deposit or withdrawal fees (PolyCop site).
Notable: copy buys only, sells only or both; take-profit and stop-loss per wallet; a filter for dust trades; a sniper for target-price entries. The site claims about 30% of copies fill in 0 seconds and the rest in around 2 seconds (PolyCop site).
Strong at: flat, easy-to-read pricing and fast setup from a phone.

PolyGun

Interface: a Telegram bot with market and limit orders and portfolio management inside the chat (PolyGun docs).
Custody: the bot "creates a safe wallet for you, but you retain full control", and you can export the private key from Settings → Wallet Security (FAQ).
Fees: a "dynamic fee curve" based on each trade's probability, charged in addition to Polymarket's own fees (FAQ, dynamic fees). Exact rates: not published in the docs.
Notable: pitched as a "high-speed trading bot" (PolyGun docs). Third-party reviews describe copy trading, but the docs pages we could reach don't detail it; copy sizing and filters: not published.
Watch for: search results show several PolyGun-branded domains with conflicting fee claims. Start from the docs and use the bot link given there.

Polycule

Interface: a Telegram bot (@polycule_trade_bot) with a companion website.
Custody: you can export your private key with the /wallet command (docs). How keys are stored: not published in the docs.
Fees: no extra charge when bridging in from Solana through deBridge (docs). Per-trade fee: not published in the docs.
Notable: sizing by percentage, fixed amount or ranges; filters on liquidity, volume and maximum odds; a "copy or counter" mode that trades against a wallet; custom sell rules (docs).
History: on 13 January 2026 Polycule was hacked and about $230,000 of user funds were taken. The team took the bot offline and promised compensation, and security analysts pointed to server-side, reversible key storage as the underlying weakness (Odaily).
Strong at: counter-trading, and users coming from Solana.

Stand.Trade

Stand's own site blocked our requests, so this section relies on secondary sources.

Interface: a web trading terminal that aggregates Polymarket and Kalshi. A March 2026 review calls it desktop-first (Gain Gorilla).
Custody: the same review describes it as non-custodial, with trades executed on-chain from your own wallet (Gain Gorilla).
Fees: the review says Stand doesn't charge on manual trades (Gain Gorilla). Copy-trading fee and Pro pricing: not published.
Notable: a Polymarket newsletter post co-written with Stand.Trade says Stand launched copy trading in February 2026 and tracked over 1,500 wallets and 5,000 strategies in two months, with category filters and budget controls (Polymarket newsletter).
Strong at: a full terminal for people who also trade by hand.

polycopy.app (unrelated to PolyZig)

polycopy.app is an unrelated product. PolyZig was called PolyCopy until April 2026, which is why the two names get confused in search results and forums.

Interface: a web app (polycopy.app).
Custody: non-custodial; the site's line is "Your keys, your capital" (polycopy.app).
Fees: Free at $0/month (feed, Copy Score, manual copying, portfolio tracking) and Premium at $30/month, which adds automated bots. A flat 0.5% trading fee applies on both tiers (polycopy.app).
Notable: a "Copy Score" that estimates what following a trader leaves you after slippage and fees, and free paper trading with its bots (polycopy.app).
Strong at: trader research that accounts for the cost of copying.

Open-source bots on GitHub

Interface: code you run yourself, usually Node.js or Python on your own server. Polymarket publishes official client libraries such bots can use (py-clob-client, clob-client).
Custody: yours alone. The key usually sits in a .env file on your machine.
Fees: no platform fee. You pay Polymarket's fees and your hosting.
Notable: full control over logic, sizing and speed, if you can code and maintain it.
Watch for: malware. In March 2026, StepSecurity documented a copy-trading repo, dev-protocol/polymarket-copytrading-bot-sport, published under a hijacked verified GitHub organization. Two typosquatted npm packages, ts-bign and big-nunber, stole .env files with wallet keys and opened an SSH backdoor (StepSecurity).
Strong at: zero platform fees and full transparency, for people who audit every dependency.

PolyZig

This is our product. It's a web app, not a Telegram trading bot.

Interface: a web app at polyzig.com in 31 languages, including Arabic and Persian. It also works as a Polymarket front end in countries where polymarket.com is geoblocked, with no VPN needed (worldwide access).
Custody: self-custody wallets, created through a Magic.link email login, or connect MetaMask or WalletConnect. Keys are encrypted at rest with AES-256-GCM, and PolyZig can't withdraw on your behalf unless you initiate it.
Fees: Free is $0/month plus 0.50% per copied trade (one copy config, positions up to $1,000). Pro is $49/month ($29 the first month) plus 0.40%, with up to five configs. HFT Elite is $249/month ($149 the first month) plus 0.30%, with up to 100 configs. No deposit or withdrawal fees. Unlike most bots on this list, the paid tiers carry a subscription.
Detection: API polling on Free, block confirmation on Pro, and mempool monitoring on HFT Elite, with sub-500ms from detection to order.
Notable: multiplier, fixed-dollar or fixed-share sizing; smart sizing that caps total exposure per market; separate buy and sell slippage; take-profit and stop-loss per config; paper trading with full P&L on any config. HFT Elite adds auto-claim, auto-sell of won positions at $0.99, auto-stop and Telegram alerts.
Strong at: paper trading, a choice of detection speeds, and access from geoblocked countries.

How to choose a Polymarket copy trading platform

Custody and key safety

Ask where the key is generated, where it's stored, and whether you can export it. "Non-custodial" on a landing page tells you little on its own. Polycule's incident shows what happens when keys sit on a server that gets breached. Prefer products that let you export your key, and don't fund a bot wallet with more than you're prepared to lose.

Detection speed

Polling, block confirmation and mempool monitoring are very different latencies. In slow political or sports markets the gap matters less. In short crypto markets and thin order books, it decides whether a copy is worth taking at all.

Fees on both sides

Add up the platform fee on the buy, the fee on the sell, any claim or redeem fee, any subscription, and Polymarket's own trading fees. A 0.5% fee charged on entry and exit costs about 1% before the price moves. A subscription can beat a percentage fee at high volume and lose to it at low volume.

Risk controls

Look for a maximum position per market, per-trade caps, slippage limits, take-profit and stop-loss, and filters that skip dust trades or illiquid markets. Without caps, a multiplier on a large trader can produce an order far bigger than you meant.

Paper trading

Run a config in simulation before funding it. polycopy.app and PolyZig both advertise paper trading; check whether any other tool you're considering offers it before you commit real money.

Security checklist

Never paste your main wallet's private key or seed phrase into a bot you don't know. Use a separate wallet funded only with what you plan to trade.
Verify the Telegram handle and domain from the product's own docs. Lookalikes are common enough that PolyCop's site tells users to "mind the underscore" in @PolyCop_BOT.
Understand who signs your trades. Odaily's analysis of the Polycule hack noted that almost all Telegram bots keep user keys on their own servers and sign from the backend.
If you run open-source code, read the dependency list before you install anything. The March 2026 GitHub malware hid in misspelled npm packages.
Export and back up your key where the product allows it, and withdraw profits regularly.
Treat "fills in 0 seconds" claims and win-rate screenshots as marketing until you've tested with small size.

Picking one

The best Polymarket copy trading bot is the one whose custody model you understand, whose fees you've added up, and whose controls you've tested on paper first. Copy trading copies decisions, not returns: you enter after the trader, you pay fees they may not, large traders can move the price against you, and a prediction market position can go to zero. Past performance doesn't predict future results. If you want to try it on PolyZig, the copy trading page explains the setup, and the best Polymarket traders to copy list shows who is leading right now. Start in paper mode and small size.
