Trader sentiment heavily favors zero or one VEI ≥4 eruption in 2026, with implied odds reflecting the absence of qualifying events through mid-year despite 47 documented eruptions worldwide. Smithsonian Global Volcanism Program data show only modest activity, lacking the >0.1 km³ ejecta volumes or sustained >10 km plumes required for VEI 4 classification on the index. Ongoing episodes at sites like Kīlauea remain effusive and sub-VEI 4, while a notable submarine event produced limited plume heights around 4 km. Historical baselines indicate VEI ≥4 events occur globally only a handful of times per decade on average, with monitoring networks reporting stable background seismicity and no rapid magmatic unrest at high-risk systems. Updated forecasts or new unrest signals before year-end could shift probabilities, though current conditions support the market's strong consensus around limited large-scale explosivity.
