The strong market-implied odds favoring no new pandemic in 2026 reflect the absence of any novel pathogen achieving sustained global human-to-human transmission through September, despite the largest recorded Bundibugyo virus Ebola outbreak in the Democratic Republic of the Congo. Declared a public health emergency of international concern by WHO in May, the filovirus outbreak has produced thousands of confirmed cases and deaths across multiple provinces but remains regionally concentrated with slowing incidence and no widespread international seeding. Other 2026 events, including Andes hantavirus clusters and Nipah detections, have stayed limited in scope without meeting pandemic thresholds. With only three months remaining, realistic shifts would require rapid evolution enabling efficient airborne spread or an undetected emergence event before year-end.
