PolymarketRules
This market will resolve to “Yes” if the World Health Organization explicitly characterizes Ebola virus disease, Ebola, any Ebola strain, or any outbreak of ebola 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 outbreak as a “pandemic.” A Public Health Emergency of International Concern (PHEIC) alone will not qualify unless it is also described as a pandemic.
- The primary resolution source for this market will be official WHO communications.
- A consensus of credible reporting may also be used.
