The strong 93.5% market-implied odds against a VEI ≥6 eruption in 2026 stem primarily from the absence of large-scale precursory signals at monitored systems. USGS alerts and global reports show only moderate ongoing activity, such as Kīlauea’s episodic fountaining, Semeru’s frequent small ash emissions, and unrest at Great Sitkin, all well below Plinian thresholds on the Volcanic Explosivity Index. Historical data indicate VEI 6+ events average fewer than one per century, with no comparable unrest at calderas like Yellowstone. While sudden escalation at an under-monitored arc volcano or rapid intensification of current systems remains possible, current seismic, deformation, and gas data offer no supporting indicators for such an outcome before year-end.
