Trader consensus for no California magnitude 7.0+ earthquake in 2026 reflects the low annual probability of such an event, consistent with USGS recurrence data for major faults like the San Andreas and San Jacinto. As of early September, statewide seismic monitoring shows only minor activity, including recent events below magnitude 4 and a 5.6 quake near Ukiah in June—the largest since 2022—with no foreshocks or strain indicators suggesting imminent rupture. With roughly three months remaining, the compressed timeframe reinforces the 90.4% implied probability. A late-year event remains possible if accumulated tectonic stress triggers sudden slip on a locked fault segment, though current observations indicate no such escalation.

This market will resolve "Yes" if the United States Geological Survey (USGS) (https://www.usgs.gov/programs/earthquake-hazards/lists-maps-and-statistics) reports at least one earthquake of moment magnitude (Mw) 7.0 or greater with an epicenter located within the state of California by December 31, 2026 at 11:59:59 PM ET. Otherwise, this market will resolve "No".
The state of California includes the entirety of California as recognized under U.S. law including offshore areas within California's territorial boundaries. Earthquakes occurring on the California border must have their USGS-listed epicenter coordinates fall within California's boundaries.
Any individual event meeting the magnitude and location criteria resolves the market "Yes", regardless of whether it is classified as a mainshock, aftershock, or foreshock.
Resolution will be based on the USGS's final reviewed magnitude, not preliminary estimates, regardless of when that review is published, but the qualifying earthquake needs to have occurred within California by December 31, 2026 at 11:59:59 PM ET. This market will resolve based on official information from USGS, however, an overwhelming consensus of credible reporting confirming a qualifying earthquake may also resolve this market in an instance where USGS becomes unavailable.
