Trader consensus on Polymarket reflects a 78% implied probability for no magnitude 9.0+ megaquake by June 30, driven by the events' extreme rarity—historically one to three globally per century, per USGS analyses—and lack of detectable precursors in current seismic data. No such earthquake has struck in 2026 despite heightened monitoring of subduction zones like Japan's Nankai Trough (70-80% chance over 30 years) and Cascadia (overdue but ~10-15% in 50 years). Recent developments, including the January 2026 Mw 8.8 Kamchatka event and routine M6+ activity worldwide, show no anomalous strain buildup or foreshock patterns on USGS networks. Ongoing real-time seismic surveillance offers the next key updates, though models underscore inherent unpredictability and baseline annual risk below 3%.

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 June 30, 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.Trader consensus on Polymarket reflects a 78% implied probability for no magnitude 9.0+ megaquake by June 30, driven by the events' extreme rarity—historically one to three globally per century, per USGS analyses—and lack of detectable precursors in current seismic data.
