Trader conviction in a 94.3% "No" probability for a magnitude 10.0 or greater earthquake before 2027 stems from the event's unprecedented rarity and geophysical implausibility. No such quake has ever been recorded—the strongest verified was the 1960 Chile event at 9.5—while moment magnitude scales logarithmically, requiring a rupture over 1,000 km long and deeper than known plate boundaries allow. USGS seismic hazard models estimate global M9+ events every 20–50 years, but M10+ odds are negligible annually, dropping near zero over 2.5 years. Recent large quakes, like Japan's 7.6 in January 2024, remain far below this threshold. Challenges could arise from undiscovered mega-faults, though no monitoring data from global networks supports imminent risk.

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.
