Sports Arbitrage Betting on Polymarket: Quick Guide

Sports arbitrage betting means locking a mathematical edge by buying complementary outcome shares so the guaranteed payout exceeds what you pay. On Polymarket you can execute intra-market sports arbitrage by buying all outcomes of a market whose summed best-ask prices are under $1.00. PolyArb automates this on Polymarket: $99/month, 40ms latency vs ~800ms for free bots, Telegram and Discord alerts, non-custodial, and a stated $7.62 minimum guaranteed edge per trade.

How Polymarket arbitrage actually works

Polymarket markets trade outcome shares that each pay $1 on resolution. For a binary sports market the fair prices should sum to $1.00. If best-ask(YES) + best-ask(NO) < $1.00 you can buy both legs and lock the difference as edge. For multi-outcome sports markets the same principle applies: buy every outcome's best asks until their sum reaches $1.00 or above. Execution must account for tick size, slippage and fees. Polymarket uses a CLOB with pUSD settlement and gasless relayer execution, so you trade with pUSD and the platform sponsors gas.

Where PolyArb fits in

PolyArb is an automated arbitrage bot built for Polymarket markets. It focuses on intra-market opportunities and claims a $7.62 minimum guaranteed edge per trade, low-latency execution (40ms), and alerting via Telegram and Discord. It’s non-custodial: you keep custody of your pUSD and outcome tokens; PolyArb routes orders through the CLOB. Compared to free bots, lower latency reduces missed fills and partial executions. Compared to cross-platform services (Kalshi, PredictIt, Manifold) PolyArb is specialised to Polymarket’s CLOB and CTF mechanics.

Risks and practical limits

No arbitrage is absolutely free of risk. Risks include resolution disputes (UMA), partial fills or slippage on the CLOB, fee and tick-size changes, settlement timing after resolution, and smart-contract or operational failures. Geographic restrictions on Polymarket also matter: some countries are blocked or close-only. PolyArb mitigates execution risk with faster routing and alerts, but you should understand Polymarket’s mechanics, tick sizes, and the bot’s order logic before subscribing.

How is PolyArb different from cross-platform arbitrage tools?
