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 peak seismic activity recorded during a defined 24-hour period, with outcomes determined by thresholds of increasing severity.

Kalshi

All markets resolve based on whether the highest magnitude earthquake reported worldwide by the USGS on September 24, 2026, between midnight and 23:59:59 UTC, meets or exceeds a specified 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 as resolving events. If USGS ComCat data is unavailable at the settlement time, resolution may be delayed according to contract contingencies. Each market corresponds to a distinct magnitude threshold, with higher thresholds representing more severe earthquake requirements.
