Major volcanic eruptions rated VEI 6 or higher remain exceptionally rare, occurring several times per century on average, which underpins the 92.5% market-implied probability of none occurring in 2026. As of mid-September, global monitoring by agencies such as the USGS and Smithsonian Global Volcanism Program shows only moderate ongoing activity at sites including Kīlauea, Great Sitkin, and Anak Krakatau, with recent events producing ash plumes under 15 km and ejecta volumes far below the ≥10 km³ threshold for VEI 6. No volcano currently exhibits the sustained pressurization, seismic swarms, or deformation patterns that typically precede such colossal Plinian or caldera-forming events. While an unforeseen escalation at a high-threat system could still alter outcomes before year-end, current observational data and climatological baselines strongly support trader consensus favoring no major eruption.
