Description

This event tracks whether a significant earthquake will occur on a specific date, measured by the magnitude reported by a leading geological survey. It focuses on the possibility of seismic activity reaching certain strength thresholds during a defined 24-hour period. Outcomes depend on whether any quake meets or exceeds these benchmarks.

Kalshi

All markets resolve based on whether the highest magnitude earthquake reported worldwide by the USGS on October 19, 2026, between midnight and 23:59:59 UTC, meets or exceeds a specific threshold ranging from 5.2 to 7.0. The magnitude used for settlement is the USGS-reported value at expiration, with moment magnitude (Mw) taking precedence when available. If multiple earthquakes share the highest magnitude, all qualify. If USGS ComCat data is unavailable at expiration, settlement may be delayed under contract contingencies. Each market corresponds to a distinct magnitude threshold, with higher thresholds representing increasingly rare seismic events.
