Trader consensus on Polymarket reflects near-certainty at 98.6% for no major solar storm—defined as G4 (Kp=8) or G5 (extreme, Kp=9) geomagnetic disturbance—by April 30, driven by NOAA Space Weather Prediction Center observations showing planetary Kp index peaking at only 5 (G1 minor) amid coronal hole high-speed solar wind effects late on April 30. Absent Earth-directed coronal mass ejections from recent M- and X-class flares earlier in April, geomagnetic activity stayed well below severe thresholds throughout the month, consistent with Solar Cycle 25's post-peak decline. While preliminary data could see minor revisions, no realistic scenarios like undetected CME impacts remain viable post-deadline, solidifying the outcome.

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".
