How many large volcano eruptions (VEI ≥4) in 2026?

Traders currently price "0" at 54% for "How many large volcano eruptions (VEI ≥4) in 2026?". Over the past 24 hours that probability moved down 3.5 points. Full distribution: 0 54%, 1 20%, 2 4%, 5+ 1%. The market has traded $1.2M in total volume and resolves Mar 31, 2027. No confirmed VEI ≥4 eruptions have occurred in the first seven months of 2026, with Smithsonian Global Volcanism Program records showing only lower-intensity events such as Dukono’s VEI 3 episode in May and ongoing explosive ash emissions at Sheveluch that have not reached the VEI 4 threshold. Global monitoring indicates typical background activity at dozens of volcanoes, but no plume heights, ejecta volumes, or explosivity metrics have met the criteria for large eruptions. Historical averages suggest roughly one to two VEI ≥4 events per year worldwide, yet the absence of any so far supports the market’s 57% implied probability for zero. Remaining uncertainty stems from the potential for rapid intensification at restless systems like Sheveluch or Indonesia’s arc volcanoes before year-end, with updated Smithsonian and national observatory reports serving as key resolution inputs.
