Trader sentiment strongly favors zero VEI ≥4 eruptions in 2026, as implied by the 64.5% market odds, given the historical rarity of such events—typically one or fewer per year on average—and the absence of any confirmed large explosive eruptions through early June despite ongoing monitoring. Smithsonian/USGS reports document around 47 total eruptions worldwide so far in 2026, but these involve mostly lower-intensity activity such as effusive lava flows at Kīlauea and persistent smaller explosions at sites like Dukono and Merapi. No VEI 4+ events have been recorded, consistent with the low baseline frequency of cataclysmic eruptions on the Volcanic Explosivity Index scale. Continued weekly volcanic activity reports through the remainder of the year will provide key updates on any intensification or new unrest that could shift probabilities.
