How this market settles

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.

What could still go wrong

  • 'Equivalent in character to NATO Article 5' is inherently interpretive — determining whether specific treaty language rises to this threshold may be disputed
  • 'Binding obligation' is not legally defined in the market description and could be contested if an agreement uses ambiguous legal language
  • Resolution relies on 'consensus of credible reporting' rather than an official legal or governmental source, introducing subjectivity
  • The Trump administration condition implicitly ties resolution to a specific administration remaining in power or acting on behalf of the US, which could be ambiguous if administration changes or personnel shifts occur
  • Executive agreements vs. treaties have different legal bindingness under US law; the market treats them equivalently, which may cause disputes
  • Taiwan Relations Act is cited as non-qualifying, but it is a statute — the line between a statutory obligation and a treaty-based obligation is not fully clarified
  • No explicit definition of what constitutes 'mutually agreed' between parties if one side disputes finalization
