Rules

This market will resolve to “Yes” if any European country formally commits to giving Ukraine a security guarantee, defined as a publicly announced and mutually agreed deal between the relevant European country and the Government of Ukraine which creates a binding obligation for the relevant European country to defend or directly intervene on Ukraine’s behalf, by June 30, 2026, 11:59 PM ET.

Polymarket
  • Otherwise, this market will resolve to “No.”
  • A qualifying “security guarantee” requires language that is equivalent in character to a NATO Article 5–style mutual defense commitment: the relevant European country must commit to responding militarily if Ukraine is attacked, or otherwise guarantee Ukraine’s defense through binding defense obligations.
  • Examples of qualifying language include commitments modeled on the US treaties with Japan, South Korea, or the Philippines, or NATO's Article 5 instrument, which obligates the United States to “act to meet the common danger” through military force if an ally is attacked.
  • Cooperative frameworks, capacity-building measures, consultative mechanisms, or nonbinding pledges will not qualify.
  • Examples of non-qualifying arrangements include the June 13, 2024 US–Ukraine bilateral security agreement, the Taiwan Relations Act, or G7/EU “security arrangements” that provide support or consultation but stop short of binding defense guarantees.
