**Trader consensus favoring zero or one VEI ≥4 eruption in 2026 stems primarily from the statistical rarity of such events—typically 0–3 globally per year—and the absence of confirmed large explosive episodes through late August.** Ongoing activity at Semeru, Manam, and several Indonesian and Philippine volcanoes remains mostly at VEI 2–3 or lower, with Kīlauea’s episodic fountaining and Etna’s Strombolian phases producing limited tephra volumes. A May submarine eruption at Titan Ridge generated a significant plume and pumice rafts but is difficult to assign a definitive VEI on the subaerial scale. Official monitoring by the Smithsonian Global Volcanism Program and national agencies shows continued low-to-moderate explosivity at most sites, with no new model runs or satellite observations indicating imminent escalation to VEI 4 thresholds. This data environment supports the market’s 46.5 % probability on zero while leaving modest room for one additional event before year-end.
