Trader consensus favors "No" at 86% implied probability for a magnitude 9.0+ earthquake before 2027, driven primarily by the extreme rarity of such megathrust events, which occur globally roughly once every 20-50 years based on USGS historical catalogs since 1900. Verified data shows only five confirmed M9+ quakes this century—1960 Chile, 1964 Alaska, 2004 Sumatra, 2011 Japan—none since Tohoku, with long recurrence intervals on major subduction zones like Cascadia (10-15% chance over 50 years) or Japan's Nankai Trough (~2-3% annual risk per recent government models). Recent developments, including January 2024's M7.6 Noto quake, lack precursors signaling an imminent M9 rupture, as seismic monitoring reveals no unusual strain buildup; inherent forecasting uncertainty tempers short-term odds further.

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.
