About This Event

Worldwide on Oct 27, 2026 If the highest USGS-reported earthquake magnitude worldwide during Oct 27, 2026 from 12:00:00 AM through 11:59:59 PM UTC is X or higher, then the market resolves to Yes. The determining value is the USGS-reported magnitude displayed at Expiration, preferentially moment magnitude, Mw, and otherwise the primary magnitude type reported by USGS. If multiple earthquakes tie for the highest magnitude, all tied earthquakes count. If USGS ComCat is unavailable at Expiration, settlement may be delayed under the Contract contingencies. This market may close and expire early once USGS has reviewed and finalized all earthquakes from the Period and the highest qualifying magnitude is known.
