How sports-bet arbitrage actually works on Polymarket

Sports markets on Polymarket are either binary (YES/NO) or multi-outcome. Intra-market arbitrage happens when the sum of best-ask prices across all outcomes is under $1.00. Buying the complete set mints a mathematically defined edge: you hold tokens that redeem to $1.00 each at resolution. The spread equals $1.00 minus the sum of best asks. Polymarket uses a Central Limit Order Book and pUSD as the settlement asset, so execution happens on-chain via the Relayer with CTF tokens.

Why PolyArb for arbitrage sports bets

Latency and execution matter: spreads often exist for seconds. PolyArb’s 40ms latency is built to capture fleeting intra-market opportunities that slower tools miss. The service is non-custodial — your wallet signs transactions — and includes Telegram and Discord alerts so you can monitor fills in real time. Pricing is $99/month and includes the platform guarantee of a $7.62 minimum edge per detected trade.

Risks, limits, and practical constraints

Arbitrage on Polymarket is not without risk. Resolution disputes via UMA, partial fills, slippage, fee changes, and settlement timing can erode returns. Geographic restrictions apply; some countries are blocked or close-only by Polymarket policy. Maker fees are zero but taker fees vary by category. PolyArb automates checks but always flags risks before execution.

Getting started and where PolyArb fits

If you already trade sports markets or are a crypto-native, connect a wallet supported by Polymarket and run PolyArb alongside your monitoring. The bot focuses on intra-market arbitrage; it does not arbitrate across other exchanges like Kalshi or PredictIt. PolyArb is best when you need deterministic edge capture on Polymarket’s CLOB and prefer a managed, low-latency tool rather than building your own bot.
