Frequently Asked Questions

What is multi-outcome arbitrage on Polymarket?▼
Multi-outcome arbitrage occurs when the sum of probabilities for all outcomes in a market is less than 100% (also called a "dutch book"). Buying shares in all outcomes guarantees a profit regardless of the result.
How do I find cross-market arbitrage opportunities?▼
Cross-market arbitrage tools compare Polymarket probabilities to identical or similar markets on Kalshi, Metaculus, Manifold, or prediction market aggregators. When the same event trades at different prices across platforms, an opportunity may exist.
Is Polymarket arbitrage risk-free?▼
Not entirely. Execution risk (slippage, timing), liquidity risk (not enough shares available), and smart contract risk are all factors. Multi-outcome arbitrage is closest to risk-free but still carries resolution and timing risk.
Do I need a bot to arbitrage Polymarket?▼
Manual arbitrage is possible for slow-moving markets. For fast price movements or automated scanning across dozens of markets, a bot that monitors and executes instantly is far more practical.
