How a Polymarket copy trade actually works

A Polymarket copy trade in practice means automating order placement so you replicate profitable actions identified by a strategy or leader. For intra-market arbitrage that usually means buying a complete set of outcome shares when the sum of best-ask prices is below $1.00, or buying both YES and NO in a binary when their asks sum below $1.00. The bot must place FAK market orders or tight limits to avoid partial fills and slippage. PolyArb connects to Polymarket's CLOB APIs, monitors best-ask levels in real time, and executes FAK orders to capture the mathematical edge. PolyArb is non-custodial: you keep custody of pUSD in your wallet while the bot instructs the Relayer to place orders on your behalf.

Latency and execution matter

Speed narrows or erases arbitrage windows. Public free bots typically see ~800ms latency, which is often too slow for short-lived spreads. PolyArb runs at 40ms median latency, improving hit rates on fleeting edges and reducing slippage exposure. Even with low latency, fills are not guaranteed. Polymarket uses a CLOB and tick-size rules, and markets can move between your signal and execution. PolyArb's architecture prioritizes immediate FAK orders and alerts so you can monitor outcomes in real time.

Fees, risks, and what "guaranteed edge" means

PolyArb advertises a $7.62 minimum guaranteed edge per trade as a baseline arithmetic edge target; this is a product guarantee from PolyArb, not a promise of net profit. Any execution still faces risks: UMA resolution disputes, partial fills or slippage, fee variation by market category, and settlement timing. You should treat copy trading and arb automation as operational tools. PolyArb provides Telegram and Discord alerts and an execution layer, but trades retain settlement and oracle risks inherent to Polymarket.

Practical setup and who should use it

Setting up PolyArb requires a Polygon wallet with pUSD and connection to the Polymarket Relayer; gas is sponsored by Polymarket. PolyArb is aimed at traders who need low-latency, non-custodial automation and who want to capture intra-Polymarket arbitrage rather than cross-platform bets. If you were searching for copy trading on other platforms (PredictIt, Kalshi, Manifold), note those are different markets and protocols. PolyArb is specific to Polymarket's CLOB and intra-market arbitrage workflows.

FAQ

Can I truly copy another trader on Polymarket with PolyArb?
PolyArb automates strategy execution rather than following individual traders. It monitors market conditions and executes arbitrage orders; if a trader publishes signals you can mirror them by configuring PolyArb, but custody and execution remain non-custodial and on-chain.
What is the $7.62 minimum guaranteed edge?
The $7.62 figure is PolyArb's advertised minimum arithmetic edge per trade target. It is a product-level guarantee, not a risk-free profit promise; realized outcomes depend on fills, fees, and resolution events.
Does PolyArb custody my funds to copy trades?
No. PolyArb is non-custodial: you retain your wallet and pUSD. PolyArb instructs the Polymarket Relayer to place orders on your behalf; all settlement and token custody remain in your wallet.
