**No** at 91% reflects the absence of qualifying extremes through mid-October 2026. Official USGS records show no magnitude 8.5+ earthquakes, with the largest events reaching only 7.7 in Panama and several 6+ quakes elsewhere. NOAA and NHC data confirm no Category 5 hurricane landfalls in the United States, while active systems like Hurricane Simon (Category 4) and Isaias (Category 2) fall short of the threshold. Smithsonian volcanism reports list no VEI 6+ eruptions, and NASA monitoring indicates no 10-kiloton+ meteor impacts. With roughly 80 days left and these events historically rare—U.S. Category 5 landfalls average fewer than one per decade—the market-implied odds align with observed conditions. A late-season rapid intensification in the Atlantic or an unexpected seismic swarm could still shift probabilities before year-end.
