Strong trader consensus for no new pandemic declaration in 2026, reflected in the 88.5% implied probability, stems from the absence of any novel pathogen exhibiting sustained global human-to-human transmission or meeting World Health Organization criteria as of mid-year. Regional outbreaks, including the Bundibugyo Ebola virus event in the Democratic Republic of the Congo and Uganda declared a Public Health Emergency of International Concern in May 2026, and the contained Andes hantavirus cases linked to a May cruise ship, have remained localized without evidence of exponential international spread. CDC and WHO surveillance data show ongoing measles and dengue activity at historical levels but no escalation toward pandemic thresholds, aligning with the rarity of such events outside major zoonotic jumps. Continued official monitoring through the year will provide further clarity on transmission dynamics.
