This market will resolve to "Yes" if a solar radiation storm with a severity level of 3 or greater occurs between market creation and April 30, 2026, 11:59PM ET. Otherwise, this market will resolve to "No". An S3 event is a solar radiation storm with a "Strong" classification. 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. 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 "No". NOAA Space Weather Prediction Center forecasts underpin the 95% market-implied odds for no major solar storm—defined by G4 or higher geomagnetic activity on the Kp index—by April 30, projecting low-to-moderate solar radio flux (F10.7 up to 160 sfu) and maximum Kp of 6 (G2 moderate) in the 27-day outlook, with no severe events anticipated. Recent G2-G3 storms from early April coronal mass ejections (CMEs) have dissipated amid quiet active regions and Solar Cycle 25's post-maximum decline, lacking Earth-directed threats in WSA-Enlil models. This evidence-based tranquility drives trader conviction. A sudden X-class flare from a new magnetically complex sunspot region could challenge this, sparking a fast CME for G4 impacts, though current monitoring shows slim odds. Daily 3-day updates from SWPC bear watching.
