Description
Earthquakes of magnitude 5.5 or higher worldwide between May 11, 2026, 12:00 AM ET and May 17, 2026, 11:59 PM ET will determine the total count. Resolution uses USGS Earthquake Hazards Program data with a 5.5+ cutoff and the specified dates; if a qualifying event appears after the window, the market may stay open through May 31, 2026, 11:59 PM ET or until the event appears on the resolution source. If necessary, a credible resolution source can be used, and the final day may allow 24 hours for magnitude revisions.

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 May 11, 2026, 12:00 AM ET, and May 17, 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.
