The leading 74.5% market-implied probability for a 2026 maximum of 7.9 or below reflects USGS records showing a current high of Mw 7.8 in the Philippines (June) amid an active year with roughly a dozen magnitude-7+ events, including recent 7.7 and 7.4 shocks in Indonesia and Colombia. Great earthquakes (Mw 8.0+) remain infrequent on global catalogs, with historical annual rates typically one to three, and the remaining four months provide limited window for an extreme outlier given current plate-boundary stress patterns monitored by agencies. Traders appear to weigh this baseline against the small but non-zero tail risk of rapid intensification along subduction zones.

The resolution source for this market is the United States Geological Survey (USGS) Earthquake Hazards Program (https://earthquake.usgs.gov/earthquakes/search/). Magnitude is measured to one decimal place (e.g., 7.9). The USGS preferred magnitude at the end of this market's open period governs; later revisions do not reopen or change this market's resolution.
An extension period extends this market's close from January 3, 2027, 11:59:59 PM ET to as late as January 7, 2027, 11:59:59 PM ET, and applies when a qualifying earthquake has occurred within this market's timeframe but the USGS has not yet published or finalized its preferred magnitude. This additional time allows the reported magnitude to be finalized before this market resolves.
This market will remain open until January 3, 2027, 11:59:59 PM ET, or until January 7, 2027, 11:59:59 PM ET if the extension period applies. If a qualifying earthquake has occurred within this market's timeframe but has not yet appeared on the resolution source by the end of that period, another credible resolution source will be used.
