This market will resolve to "Yes" if a natural volcanic eruption with a Volcanic Explosivity Index (VEI) of 6 or higher occurs between the market's creation and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. The primary resolution source will be the Smithsonian Institution Global Volcanism Program (GVP: https://volcano.si.edu/), specifically the ‘VEI 6’ figure for 2026 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.Current monitoring from the USGS and Smithsonian Global Volcanism Program shows only routine low-to-moderate activity at volcanoes such as Kīlauea, Semeru, and Etna, with no systems displaying the prolonged precursory unrest or rapid magma ascent needed for a VEI ≥6 event. These eruptions, which eject at least 10 km³ of tephra, occur globally roughly once every 85 years on average, making the remaining four months of 2026 statistically improbable absent extraordinary signals. Market-implied odds of 90%+ for no eruption reflect this baseline frequency plus the absence of alerts at high-threat calderas. An unexpected VEI 6 could still develop from rapid escalation at an unmonitored or underestimated system, though historical patterns and current data provide little indication of such a shift before year-end.
