**Global M6.5+ earthquakes follow a relatively stable long-term rate of roughly one event every eight days on average (about 46 per year), producing an expected value near 0.9 events per week.** This Poisson-like distribution, drawn from USGS and historical catalogs, places a single event as the mode for any seven-day window, directly supporting the market’s leading 39% implied probability for exactly one occurrence during September 7–13. Recent data reinforce this baseline. The past several days have featured isolated M6.0–6.3 events (e.g., 6.3 near Unalaska, Alaska on September 3 and 6.2 in the South Sandwich Islands region on September 2), but no M6.5+ quakes or active aftershock sequences capable of elevating short-term rates. 2026 overall remains near or slightly below the long-term average for large events, with no anomalous clustering or triggering indicators reported by monitoring agencies. Traders therefore price outcomes around the climatological mean: 0 events at 25.5% and 2 events at 22.5% reflect the natural variance, while probabilities decline sharply beyond three. Upcoming resolution will hinge on USGS/NEIC catalog updates, which count only confirmed, reviewed events meeting the magnitude and global geographic criteria.
