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 12, 2026, 12:00AM ET and April 18, 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.Trader consensus on Polymarket overwhelmingly favors fewer than three major space weather events from April 12-18, 2026, with <3 shares at 100% implied probability, backed by NOAA Space Weather Prediction Center (SWPC) observations confirming zero qualifying incidents. No G3 (strong) or higher geomagnetic storms, S3 (strong) solar radiation storms, or R3 (strong) radio blackouts occurred, as solar activity stayed low after the last M1 flare on April 9 amid a mostly spotless solar disk and absent Earth-directed coronal mass ejections. A coronal hole high-speed solar wind stream prompted G2 (moderate) geomagnetic watches for April 17-18, but activity peaked below strong thresholds. Resolution is near-certain absent rare post-hoc reclassifications from preliminary data.
