Description
Earthquakes of magnitude 5.5 or higher worldwide from April 27, 2026 12:00 AM ET to May 3, 2026 11:59 PM ET are counted toward the eight possible outcome buckets. The tally resolves based on USGS Earthquake Hazards Program data within that window, with May 31, 2026 11:59 PM ET as a potential open period for late-reported events and a fallback if needed. If a qualifying event appears on the final day or during the open window, data may be revised within 24 hours before final settlement.

This market will resolve according to the total number of earthquakes with a magnitude of 5.5 or higher that occur anywhere on Earth between April 27, 2026, 12:00 AM ET, and May 3, 2026, 11:59 PM ET. The resolution source for this market is the United States Geological Survey (USGS) Earthquake Hazards Program, with the minimum magnitude set to 5.5 and the date parameters set to the relevant dates for this market's timeframe (https://earthquake.usgs.gov/earthquakes/search/). If an earthquake of substantial size has occurred within this market's timeframe but not yet appeared on the resolution source, this market may remain open until May 31, 2026, 11:59 PM ET, or until the earthquake in question otherwise appears on the resolution source. If such an earthquake has not appeared on the resolution source by that date, another credible resolution source will be used. This market may not resolve until the timeframe of this market has concluded. If a qualifying earthquake has been recorded on the final day, this market may remain open for 24 hours to allow for revisions to the recorded magnitude. After 24 hours, this market will resolve according to the latest provided data.
