Polymarket arbitrage tools and bots | Page 2
Use these tools to investigate cross-market price differences and possible arbitrage. A displayed spread is a starting point for checking the contracts and the trade, not proof that both legs can be executed.
How to choose arbitrage
Verify the event before the price
Similar questions can settle differently or face different trading constraints. Compare the exact outcomes and rules before assuming that positions offset one another.
Evaluate the complete trade
- Account for fees on the intended legs.
- Check fill risk and the capital required to complete the trade.
- Identify incompatible outcomes and settlement differences.
- Distinguish price comparison from documented execution support.
