Markets stay open until the event is over. Once the outcome becomes publicly known, the Exchange determines the result using publicly verifiable information.

​
How Market Outcomes Are Determined

Each market asks a clear question about a real-world event. When the outcome becomes publicly known, the Exchange confirms it using the criteria defined in the market’s description and rules. The Exchange relies on publicly verifiable information from official and reputable sources, such as:
  • League or governing-body websites
  • Government publications or election authorities
  • Major, established media outlets
All determinations follow the event-contract framework used across Polymarket US.

​
Timing of Resolution

Resolution occurs after the event outcome is publicly confirmed.
  • Sports markets: Often resolve shortly after the official result is posted
  • Political or news markets: May take longer if certification or official publication is required
  • Complex events: May require additional verification before resolution
Resolution timing varies by event and depends on when reliable information becomes available.

​
After Resolution

When a market resolves:
  • Winning shares settle at $1.00
  • Losing shares settle at $0.00
  • Your Portfolio updates automatically when settlement completes

​
Finality of Resolution

All resolutions are final in accordance with the Polymarket US Exchange Rulebook.
