This market will resolve to “Yes” if any official authority publicly confirms that the liquid sprayed on Ilhan Omar at the January 27, 2026 Minneapolis town hall contained a poison or toxin, or otherwise posed a meaningful toxicological health risk. Otherwise, this market will resolve to “No”. If no broad consensus from credible reporting and authoritative statements has been reached by February 28, 2026, 11:59 PM ET, this market will resolve to “No.” If the substance is confirmed to be a mixture, this market will resolve to “Yes” if any component is officially identified as a poison or toxin or is stated by authorities to pose a toxicological health risk. Descriptions of the substance as “unknown,” “unidentified,” “foul-smelling,” “irritating,” or precautionary testing or investigation alone will not qualify without an official determination of toxicological risk. The resolution source will be a consensus of credible reporting and official statements.
