Prediction Market Arbitrage on Polymarket with PolyArb

Prediction market arbitrage exploits price inconsistencies inside a single market to lock in a mathematical edge. On Polymarket that means buying a full set of outcome shares when the summed best-asks are below $1.00, or buying both YES and NO in a binary market. These opportunities are short-lived; execution speed, reliable fills, and fee awareness determine whether a spread converts to cash. PolyArb is a live, non-custodial bot that routes orders on Polymarket and advertises a $7.62 minimum guaranteed edge per trade.

How Polymarket arbitrage actually works

Polymarket uses a Central Limit Order Book (CLOB) and sells outcome shares that each pay $1.00 if their outcome resolves YES. Intra-market arbitrage happens when the sum of best-ask prices across mutually exclusive outcomes is less than $1.00. Buying that complete set and later redeeming the winning token for $1.00 locks in the difference as edge, subject to fees and settlement timing. For binaries, the check is simply bestAsk(YES) + bestAsk(NO) < $1.00.

Execution factors that matter

Latency and order type matter because spreads often last seconds. PolyArb advertises ~40ms latency versus ~800ms for free bots and sends Telegram and Discord alerts for fills and opportunities. Maker fees are zero on Polymarket; taker fees vary by category. Slippage, partial fills, and tick-size changes near extremes can erode projected profit, so watch the live book and prefer FAK/market orders when necessary.

Risks you must account for

Never treat arbitrage as unconditional risk-free profit. Risks include resolution disputes via the UMA oracle, settlement timing and liquidity risk, smart-contract or relayer outages, and geo-restrictions that can block order placement. Fees can change by category, and extreme price moves before settlement can cause losses. PolyArb reduces execution risk but does not eliminate oracle, regulatory, or smart-contract risk.

Where PolyArb fits compared with other venues

Cross-platform arbitrage (Polymarket vs PredictIt, Kalshi, Manifold) is different and out of scope for the PolyArb bot, which focuses on intra-Polymarket opportunities. If you’re comparing tools, evaluate latency, non-custodial design, alerting, and stated guarantees. PolyArb is a paid service ($99/month), live today, and emphasizes speed, guaranteed minimum edge per trade, and push alerts.
