Trader consensus at 97.6% for "No" megaquake (magnitude 9.0+) by March 31 reflects the extreme rarity of such events, with global historical data showing roughly one every 20–50 years from major subduction zones, implying less than 3% odds over three months. Recent Japan activity, including the January 1 Noto Peninsula M7.6 quake, heightened public concern but lacks precursors like widespread foreshocks or strain anomalies per Japan Meteorological Agency and USGS seismic networks. No unusual global tectonic signals—such as accelerated slip deficits—elevate short-term risks. Realistic scenarios remain limited to sudden full-zone ruptures in hotspots like Nankai Trough or Cascadia, though monitoring shows stable conditions.

A "megaquake" is defined as an earthquake with a magnitude of 8.0 or greater.
This market will resolve to “Yes” if 1 or more earthquakes with a magnitude of 8.0 or higher occur anywhere on Earth between market creation and March 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”.
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 the end of the seventh day after the resolution time, 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.
