Resolution rules

This market will resolve according to the number of geomagnetic storms, solar radiation storms, or radio blackouts with a severity level of 3 or greater which occur between April 19, 2026, 12:00AM ET and April 25, 2026, 11:59PM ET. Otherwise, this market will resolve to "No". A G3 event is a geomagnetic storm with a classification indicating "Strong". An S3 event is a solar radiation storm with a "Strong" classification. An R3 event is a radio blackout event with a classification indicating "Strong". More information on the space weather classification criteria can be found here: https://www.swpc.noaa.gov/noaa-scales-explanation This market will resolve immediately upon the occurrence of a qualifying event. Any later revisions or corrections will not be considered. Only the initial report of an ongoing event with multiple reports will qualify, unless the rating of the event is upgraded to a qualifying level from a non-qualifying level within this market's timeframe. If the reported data falls exactly between two brackets, this market will resolve to the higher range bracket. This market will resolve based on information from the National Oceanic and Atmospheric Administration's Space Weather Prediction Center under the heading marked "Current Space Weather Conditions". (https://www.swpc.noaa.gov/products/alerts-watches-and-warnings#) If the resolution source becomes permanently unavailable, this market will resolve to the lowest bracket.
