How many large volcano eruptions (VEI ≥4) in 2026?
6 markets · 8mo
The market strongly expects zero VEI≥4 eruptions in 2026, with a 67% probability, reflecting that no such event has occurred in the first seven months and the historical rarity of these eruptions.
📊 Base rate: Based on the Global Volcanism Program's record, the average annual number of VEI≥4 eruptions is about 0.8, implying a roughly 55% chance of at least one in a given year, but the conditional probability given no eruption by July is lower.
What's driving it
- • No VEI≥4 eruption has been recorded in 2026 through July 25, as implied by the 67% probability for zero.
- • The market assigns only a 20% chance to exactly one eruption, indicating low confidence in a single event.
- • The odds for two or more eruptions are below 5%, showing that multiple large eruptions are considered extremely unlikely.
The bullish case
- • The first seven months of 2026 have passed without a VEI≥4 eruption, reducing the remaining time window for such an event.
- • Historical data shows that VEI≥4 eruptions are infrequent, with an average of less than one per year, making zero a plausible outcome.
- • The market's high probability for zero suggests that traders see no imminent threats from known volcanic systems.
The bearish case
- • The year is only half over, and VEI≥4 eruptions can occur at any time, including later in the year, as seen in past events.
- • The historical base rate suggests a significant chance of at least one eruption in a given year, and the current odds for zero may be overconfident.
- • Some volcanic systems are known to be restless, and an eruption could happen with little warning, potentially shifting the count.
What to watch
- • The market's final resolution on December 31, 2026, will determine the outcome, but no intermediate catalysts are apparent from the odds.
- • Any report of a VEI≥4 eruption in the coming months would immediately shift the market towards higher counts.
- • Increased seismic activity at known volcanoes could be a precursor, but no such events are currently highlighted in the provided data.
