Polymarket Arbitrage Bot: PolyArb for Fast, Low-Risk Arb
Searching for a "polymarket arbitrage bot" means you want predictable intra-market edge and execution speed. PolyArb is a non-custodial bot that scans Polymarket for intra-market binary and multi-outcome opportunities and routes trades through the CLOB. It advertises a $7.62 minimum guaranteed edge, 40ms latency versus ~800ms for free bots, and Telegram + Discord alerts. Read on for how it works, what risks remain, and whether PolyArb fits your workflow.
How Polymarket arbitrage actually works
Intra-market arbitrage on Polymarket means buying a complete set of outcomes when the sum of best-ask prices is below $1.00. For binaries that’s buying YES and NO when bestAsk(YES)+bestAsk(NO) < $1.00. For multi-outcome markets you buy every outcome to lock the difference as an edge. PolyArb continuously monitors the CLOB, submits FAK orders through the Relayer, and uses split/merge CTF operations to hold or redeem complete sets. The math behind the edge is simple, but execution depends on tick size, taker fees, and fills.
Execution speed, fills, and the $7.62 guarantee
Latency matters: orders that look arbitrageable for seconds can evaporate in milliseconds. PolyArb advertises 40ms latency vs ~800ms for free bots, which improves fill probability on thin spreads. The product also advertises a $7.62 minimum guaranteed edge per trade; that figure is a product claim about protected edge on qualifying fills. No execution model is perfect: partial fills, slippage, changing tick size, and taker fees (0–1.8% depending on category) all affect realized profit. PolyArb’s monitoring and alerting aim to reduce but cannot eliminate those execution risks.
What risks are still present
Even with a mathematical edge, several non-market risks remain. Resolution risk from UMA disputes can delay or change settlement. Smart-contract and settlement-timing risk can impact when you access redeemed pUSD. Geo-blocking rules may restrict order placement from certain jurisdictions and using a VPN is prohibited. PolyArb is non-custodial so you retain ownership of wallet keys, but you must still manage approvals and split/merge actions. Always understand taker fee rates for the market’s tag — fees can turn a thin edge into a loss.
