What this market actually measures

This market will resolve to "Yes" if the World Health Organization explicitly characterizes Hantavirus, Hantavirus Pulmonary Syndrome (HPS), Hemorrhagic Fever with Renal Syndrome (HFRS), or a Hantavirus-related 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".

This summary shows the opening of the venue's official rules. ProbCast has not yet generated an independent plain-English interpretation for this contract — review the full rules before relying on it.

View full official resolution rules

This market will resolve to "Yes" if the World Health Organization explicitly characterizes Hantavirus, Hantavirus Pulmonary Syndrome (HPS), Hemorrhagic Fever with Renal Syndrome (HFRS), or a Hantavirus-related 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 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.

What could move this market next?

  • The market's deadline arrivesDecember 30, 2026 at 7:00 PM ET
