Trader consensus favors exactly one large volcanic eruption (Volcanic Explosivity Index, or VEI, ≥4) at 44.5% market-implied probability for 2026, with zero at 32%, reflecting the Smithsonian Global Volcanism Program's confirmation of none through late March despite 41-45 volcanoes in ongoing low-level activity. This positioning stems from historical baselines of roughly 0-2 VEI≥4 events annually worldwide, with no long-term uptick in global volcanism per GVP data spanning decades. Recent weekly reports highlight unrest at sites like Semeru and Kīlauea—effusive or Strombolian styles below VEI 4 thresholds—but no escalated seismicity, gas emissions, or deformation signaling major explosions. Uncertainties persist in unpredictable magmatic systems; key updates from GVP bulletins and USGS monitoring could shift odds as the year progresses.

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.
