A resolution proposal has a challenge clock

The event ends, the answer looks clear, and someone asks why the market has not settled yet. The missing piece is often the resolution clock.

Polymarket's resolution documentation describes a proposal, a challenge period, and additional dispute paths for UMA-resolved prediction markets. Treat those phases as market state, not as an administrative footnote.

Proposal is not finality

A proposer selects an outcome and posts a bond. The proposal then enters a two-hour challenge period. If nobody disputes it, the proposal can be accepted and the market resolves.

A correct-looking headline does not skip that process. Record the proposal time and the end of the challenge window before estimating when a position becomes redeemable.

Disputes add their own timeline

A dispute starts another proposal round. If the second proposal is disputed too, the process can escalate to a UMA vote after an evidence and debate period. The documented debate and voting stages can take days rather than hours.

Keep an unresolved proposal separate from a rejected proposal and from a market that has completed resolution. They imply different next actions and different timing risk.

Check what the rules allow

Resolution rules name the source, end date, and edge cases. A proposal made too early or against those rules can be challenged even when the eventual headline seems obvious.

The useful question is not only which outcome looks right. It is which phase the market is in, what the rules permit next, and when the winning token can actually be redeemed.
