Resolution rules
This market will resolve to "Yes" if a confirmed case of pneumonic plague in a human is reported in the Russian Federation at any point between market creation and the specified date, 11:59 PM Moscow time, . Otherwise, this market will resolve to "No". A "confirmed case" is a case explicitly identified by a qualifying source as laboratory-confirmed Yersinia pestis infection with pneumonic (pulmonary) involvement, or explicitly announced as a confirmed pneumonic plague case. Publication of the underlying laboratory results is not required. A bubonic or septicemic case that progresses to pneumonic plague qualifies. A case reported only as "plague" with no form specified, and a case described only as suspected or probable, do not qualify. The case must be distinct from the Irkutsk Anti-Plague Research Institute employee who reportedly passed away on October 1, 2026; subsequent confirmation, reclassification, or post-mortem testing of that patient will not qualify. Resolution turns on the date a qualifying source publishes the confirmation, not the date of exposure, symptom onset, or laboratory result. A report published after the deadline does not count even if the infection occurred earlier. The primary resolution sources for this market will be official information from Russian federal or regional public health authorities and the WHO; however a consensus of credible sources will also suffice.

FAQ
How are prediction market odds calculated?
Each contract pays $1 if the outcome happens and $0 if it doesn't, so its price is the market's implied probability: a 60¢ contract means roughly a 60% chance. We show the last trade, or the midpoint between the best bid and ask when the order book is tight.
When does this market close?
Polymarket lists Nov 1, 2026 as the end date; this market has closed.
