Trader consensus on Polymarket reflects a 95.4% implied probability for no magnitude 9.0 or greater earthquake before 2027, driven by the extreme rarity of such megathrust events on subduction zones, with U.S. Geological Survey (USGS) records showing none since the 2011 Mw 9.1 Tohoku quake—only five instrumentally recorded globally since 1900. Theoretical recurrence is one to three per century amid irregular clustering, and recent activity like the Mw 8.8 Kamchatka event in July 2025 and Mw 7.4 off Japan in April 2026 released stress without reaching M9 thresholds. With under eight months remaining, no unusual precursors appear in USGS monitoring of high-risk zones like Cascadia or Chile; a surprise full-plate rupture could shift odds, but seismic data indicate low near-term 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.
