Current trader consensus favors zero or one major space weather event this week, driven by NOAA Space Weather Prediction Center forecasts showing predominantly low solar activity with only a modest chance of isolated M-class flares from existing sunspot regions. Persistent coronal hole high-speed streams are expected to produce minor G1 geomagnetic conditions early in the period, falling short of major storm thresholds on the NOAA scale. With the Sun in the declining phase of Solar Cycle 25 and sunspot numbers holding near 90, the absence of complex active regions or Earth-directed coronal mass ejections keeps probabilities for multiple events subdued. Updated 3-day forecasts and any new X-ray flare detections will be the key data points that could shift positioning before the week closes.

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 May 17, 2026, 12:00AM ET and May 23, 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#.
