Trader consensus on Polymarket leans slightly toward one (44%) large volcanic eruption (Volcanic Explosivity Index, or VEI, ≥4) in 2026 over zero (37.5%), mirroring the historical global average of 0.5–0.8 such events per year tracked by the Smithsonian Global Volcanism Program's Holocene database and recent decades' records (e.g., two in 2023 at Sheveluch in Kamchatka and Reykjanes in Iceland). This Poisson-distributed baseline reflects steady tectonic drivers at hotspots like the Ring of Fire, with no observed uptick in pre-eruptive signals—such as seismic swarms or ground deformation—from USGS Volcano Hazards Program and international monitoring networks in the past 30 days. Uncertainties arise from magma recharge unpredictability and post-eruption VEI confirmations, keeping tails for 2+ outcomes viable amid normal variability; traders await 2026's unfolding observatory reports for resolution.

The primary resolution source will be the Smithsonian Institution Global Volcanism Program (GVP: https://volcano.si.edu/), specifically the cumulative figures for 2026 for VEI 4, VEI 5, and VEI 6 released on the page currently titled "Eruptions Avg 2000-2024 (N/T)" (https://volcano.si.edu/faq/index.cfm?question=eruptionsbyyear) as of March 31, 2027, 12 PM ET. Any prior updates will not be considered finalized.
If this dataset has not been updated to include all relevant events by March 31, 2027, or if the Smithsonian GVP becomes permanently unavailable, this market may resolve based on a consensus of credible scientific sources, including the U.S. Geological Survey (USGS), national or regional volcanic observatories, or credible reporting of a scientific consensus.
Note: Smithsonian Institution Global Volcanism Program databases, which include eruptions that reached the relevant threshold prior to this market’s timeframe (e.g., https://volcano.si.edu/faq/index.cfm?question=eruptionsbyyear&checkyear=2025), will not be considered.
