Dispute Resolution
Sometimes market resolutions are challenged. Here's how Polymarket's dispute process works.
How Resolution Works (Normal)
| Step | What Happens | Timeline |
|---|---|---|
| Event occurs | Real-world outcome is determined | Day 0 |
| Proposal submitted | Someone proposes the correct outcome | Hours |
| Challenge period | Anyone can dispute if they disagree | 2-4 hours |
| Resolution | If no dispute, outcome is finalized | Same day |
Most markets resolve smoothly within hours.
When Disputes Happen
A dispute is filed when someone believes the proposed resolution is incorrect.
| Dispute Reason | Example |
|---|---|
| Wrong outcome | Proposer said YES but event didn't happen |
| Ambiguous rules | Market criteria unclear |
| Timing issue | Event happened after deadline |
| Source disagreement | Different sources report different results |
The UMA Oracle Process
Polymarket uses UMA (Universal Market Access) for dispute resolution:
| Phase | Duration | What Happens |
|---|---|---|
| 1. Dispute filed | Instant | Challenger stakes tokens |
| 2. Voting period | 24-48 hours | UMA token holders vote |
| 3. Resolution | After voting | Majority decision wins |
| 4. Settlement | Immediate | Market resolves per vote |
Who Can Dispute?
| Participant | Can Dispute? | Requirement |
|---|---|---|
| Anyone | Yes | Must stake UMA tokens |
| Market traders | Yes | No special requirement |
| Random observers | Yes | Must have UMA tokens |
The staking requirement prevents frivolous disputes.
Dispute Economics
| Outcome | What Happens |
|---|---|
| Dispute succeeds | Challenger gets their stake back + reward |
| Dispute fails | Challenger loses their stake |
| Voters | Earn rewards for participating correctly |
This creates strong incentives for honest resolution.
Extended Timelines
| Scenario | Resolution Time |
|---|---|
| No dispute | 2-8 hours |
| Disputed (clear) | 24-48 hours |
| Disputed (complex) | 48-72 hours |
| Multiple disputes | Up to 1 week |

FAQ
Can I dispute a resolution?
Yes, but you need UMA tokens to stake. Visit vote.umaproject.org to participate.
Will I lose money during a dispute?
No - your position is safe. Disputes only affect timing, not your ultimate payout (assuming you're on the winning side).
What if the dispute goes against me?
The market resolves according to the vote. If you held the losing outcome, your shares become worthless as normal.
