Recent seismic monitoring by the USGS confirms exactly 12 earthquakes of magnitude 5.5 or greater worldwide during October 5–11, 2026, driving the market’s overwhelming 97.5% implied probability for that outcome. A notable cluster of events in Panama, including a 7.7 mainshock and several aftershocks above the threshold, combined with independent quakes near Vanuatu (6.3), Papua New Guinea (6.2), the Kuril Islands (5.8), Alaska (5.5), and Macquarie Island, produced the precise total. This aligns with typical weekly global rates of roughly 10–15 such events on the moment magnitude scale. Only a late revision to an existing catalog entry or an overlooked event near the magnitude cutoff could alter the count, though official reviewed data make such changes unlikely before resolution.
