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 26, 2026, 12:00AM ET and May 2, 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 may not resolve until the end of the relevant timeframe. This market will resolve according to the final number of qualifying events at the end of this market's timeframe to allow for revisions to the data. 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 in the "ALERTS, WATCHES AND WARNINGS" table located under the heading titled "Current Space Weather Conditions" at 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 heavily favors zero major space weather events (76.5% implied probability) for April 26–May 2, driven by NOAA Space Weather Prediction Center data showing quiet conditions through April 30: solar wind at 391 km/s with no G3+ geomagnetic storms, S3+ radiation storms, or X-class flares observed. An M1.11 flare on April 28 and recent C-class events fell short of major thresholds, while sunspot regions remain low-complexity. Forecasts indicate continued low activity, with only 10% odds for S1+ storms and no G3+ predicted through May 2, though new active regions could spark minor upticks. Traders eye daily SWPC updates for any coronal hole high-speed stream influences.
