# 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.
