This market will resolve to “Yes” if the United States formally commits to giving Ukraine a security guarantee, defined as a publicly announced and mutually agreed deal between the Trump administration and the Government of Ukraine, which creates a binding obligation for the United States to defend or directly intervene on Ukraine’s behalf, by December 31, 2026, 11:59 PM ET. 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 United States 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. A qualifying agreement must be jointly announced and finalized, and take the form of a treaty, executive agreement, memorandum of understanding, joint declaration, or equivalent written instrument. Announcements that are statements of intent, contingent, exploratory, or otherwise not indicative of a formalized policy will not count. The primary resolution source will be a consensus of credible reporting.Ongoing negotiations between the US, Ukraine, and Russia have advanced bilateral security discussions and arms support packages, including a recent $2.7 billion US-approved air defense sale, yet major barriers persist on territorial concessions and the scope of any binding commitments. US envoys visited Moscow and Kyiv in September 2026 for talks aimed at de-escalation, with further leader-level meetings planned around the UN General Assembly, but Russian demands on territory and limits on Ukrainian forces remain unresolved. Earlier 2026 proposals for 15-year guarantees tied to a ceasefire have not produced a finalized agreement, leaving traders with little expectation of completion by year-end amid continued battlefield activity and coalition coordination efforts.
