The 94.5% market-implied probability of no new pandemic in 2026 reflects the absence through mid-August of any novel pathogen meeting criteria for sustained global human-to-human transmission and widespread geographic spread. Official surveillance from WHO and CDC shows only regional threats such as Ebola outbreaks in Central Africa, which triggered localized Public Health Emergencies of International Concern, alongside seasonal endemic COVID-19 surges without escalation to pandemic status. Historical patterns of zoonotic spillover and influenza reassortment underscore the low near-term likelihood, though rapid viral evolution or undetected emergence of a high-transmissibility strain could still shift dynamics before year-end.
