Traders heavily favor zero VEI ≥4 eruptions in 2026 at 63% implied probability because such events remain statistically uncommon, with global averages historically near one or fewer annually according to Smithsonian Global Volcanism Program records. No confirmed VEI 4+ events have occurred through mid-year despite dozens of smaller eruptions tracked by USGS and GVP monitoring, reflecting subdued activity at major systems and the absence of significant seismic or deformation signals that typically precede Plinian-scale explosions. Model consensus and recent observational data show continued lower-intensity output, with resolution depending on strict VEI criteria tied to plume height, ejecta volume, and explosivity metrics. New GVP updates or satellite observations of unrest at high-risk volcanoes could shift odds if thresholds are approached before year-end.
