This market will resolve to "Yes" if Russia takes a qualifying military action against an EU member state between market creation and the specified date, 11:59 PM ET. Otherwise, this market will resolve to "No". A qualifying military action refers to an air strike or a surface-to-surface missile strike, initiated by Russia, that directly impacts an EU member state. An air strike includes bombs, air-to-surface missiles, and air-launched drones. A surface-to-surface missile strike includes one-way attack drones and surface-to-surface missiles such as cruise or ballistic missiles. The qualifying military action must be carried out by the armed forces of Russia. Actions carried out by private military contractors, mercenaries, proxy forces, or the armed forces of any other state, including Belarus, will not qualify. An "EU member state" refers to any of the 27 member states of the European Union as of market creation: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czechia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, and Sweden. The following actions do not constitute a qualifying military action: Munitions destroyed or intercepted before impact; Surface-to-air missile strikes; Small-arms fire; Ground incursions; Cyber operations; Naval gunfire and artillery fire; Howitzers, artillery pieces, mortars, and rocket artillery (e.g. MLRS systems); Minor surface-to-surface strikes, including short range loitering munitions, FPV drones, and ATGM strikes; Sabotage, arson, or other covert acts not carried out with the munitions described above; Any threat, authorization, or announcement of force that has not been executed. Any munition that is intercepted or destroyed before impact does not constitute a qualifying military action. Debris, fragments, or any wreckage from intercepted munitions that land on an EU member state do not constitute a military action regardless of any damage incurred. Munitions that enter the territory of an EU member state in the course of a Russian attack on a non-EU country, including Ukraine, will not qualify unless a consensus of information available from the resolution sources indicates that the munition was directed at a target within the EU member state. A strike on an EU member state that is claimed by the Russian government or military will qualify. The territory of an EU member state refers to its terrestrial territory, including its internal waters. Maritime territory and airspace are not encompassed. Territories of member states to which the EU treaties do not apply, including Greenland, the Faroe Islands, and the overseas countries and territories associated with the EU, will not qualify. Where territorial borders are disputed, all territory claimed by and under the de facto control of the EU member state as of market creation will qualify. The occurrence, attribution, and timing of a qualifying military action will be primarily determined based on a consensus of information available from the resolution sources. Where multiple sources conflict regarding the occurrence, attribution, or timing of a relevant military action, this market will remain open until the earlier of: i) the confirmation of the occurrence, attribution, and timing of the action based on a consensus of information available from the resolution sources or ii) 3 full calendar days (ET) from the date of the first credibly reported evidence of the action. If this period would extend past the end date, this market will remain open to allow for 3 full calendar days to pass. At the end of the third calendar day, if conflicting reports remain, the incident will be adjudicated based on the totality of information available from the resolution sources at that time. No single statement, denial, or presentation of evidence will govern where it is contradicted by the totality of information. The resolution sources for this market will be official information from the governments and militaries of Russia and the relevant EU member state, official information from NATO and the European Union, and a consensus of credible reporting.European officials have issued urgent warnings in mid-September 2026 of potential Russian drone or missile strikes on NATO territory in the coming months, possibly framed as accidents to test Article 5 commitments. Polish Prime Minister Donald Tusk highlighted intelligence pointing to such risks for countries supporting Ukraine, while French President Emmanuel Macron described an intensified hybrid threat and directed new critical infrastructure protections. Recent incidents include Russian drone incursions into Polish, Lithuanian, and Romanian airspace, an attributed explosives-laden drone near Germany’s Leipzig airport, and strikes near the Polish border. NATO sees no imminent conventional attack or troop massing but reports heightened readiness for escalation or false-flag operations. Russia denies aggressive intentions toward Europe while continuing its campaign in Ukraine. These kinetic and hybrid developments, alongside European defensive preparations, inform trader assessments of direct military action risks.

This market will resolve to "Yes" if Russia takes a qualifying military action against an EU member state between market creation and the specified date, 11:59 PM ET. Otherwise, this market will resolve to "No".
