FAQ

Here are the most common questions about verifying.

Can I verify a proposal after two hours?

No. Once the two-hour challenge period ends, if the proposal is not disputed, the market resolves. Later verifications will not affect the outcome.

What happens if an incorrect proposal is verified?

If an incorrect proposal is verified and goes undisputed, Polymarket may pay out the wrong side of the market.

Why verify instead of propose?

Verifying lets you see how proposals are reviewed and resolved. By observing others or verifying yourself, you learn what makes a proposal accurate or rejected.

How much do verifiers earn in rewards?

Verification team members can earn up to 2 UMA for each correct verification. Incorrect verifications can result in a penalty of up to 4 UMA.

Why are there rewards?

Rewards motivate verifiers to review proposals carefully and catch errors. Polymarket's system rewards proposers and disputers, while UMA provides separate incentives for verification team members.

How often do verifiers disagree?

Disagreements happen, especially in close or subjective markets. When this occurs, verifiers review each other's findings to identify what caused the difference and reach a consensus.

What if I disagree with a verification?

If you disagree with a verification, you can discuss it with UMA community members to understand their reasoning. You can also choose to dispute the market directly.
