Plague pandemic in 2026?

Polymarket — resolution criteria

This market will resolve to "Yes" if the World Health Organization explicitly characterizes plague, Yersinia pestis, pneumonic plague, or any plague outbreak as a "pandemic" in an official public communication between market creation and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". An explicit characterization includes official WHO statements, reports, press briefings, or publications that clearly describe the disease or outbreak as a "pandemic". A Public Health Emergency of International Concern alone will not qualify unless it is also described as a pandemic. The primary resolution source for this market will be official WHO communications; however, a consensus of credible reporting may also be used.
