No new pandemic has emerged through mid-August 2026, supporting the 93.5% market-implied odds against one this year. Official CDC and WHO surveillance shows low influenza activity, very low COVID-19 emergency visits with modest Rt estimates around 1.08, and no sustained human-to-human transmission of novel high-risk pathogens such as Marburg or emerging coronaviruses. Routine respiratory monitoring and absence of WHO pandemic declarations reflect limited zoonotic spillovers reaching epidemic thresholds. Traders weigh this data alongside historical rarity of pandemics and improved post-COVID surveillance. A late-year surprise—such as rapid adaptation of influenza D, canine coronavirus, or an undetected Disease X—could still shift outcomes before year-end.
