The 95% market-implied probability for no magnitude 10.0 or greater earthquake before 2027 reflects U.S. Geological Survey (USGS) consensus that such events are physically impossible on Earth. Moment magnitude, which quantifies total seismic energy release from fault rupture length and area, limits the maximum to about 9.6 on the longest subduction zones, as in the record 9.5 Valdivia event of 1960—no larger quake has ever been instrumentally recorded. Recent USGS seismic catalogs through May 2026 show routine global activity with no precursors to superquakes, reinforcing trader confidence backed by real capital. Realistic shifts would demand revised fault models or an unprecedented full-plate rupture, scenarios experts consider negligible amid continuous monitoring.

The resolution source for this market is the United States Geological Survey (USGS) Earthquake Hazards Program (https://earthquake.usgs.gov/earthquakes/browse/significant.php#sigdef).
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 January 31, 2027, 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.
After a qualifying earthquake is registered, this market will remain open for 24 hours to account for any revisions to its recorded magnitude. After 24 hours, this market will resolve according to the latest provided data.
