**Traders assign a 94% probability to “No” primarily because the remaining timeline to the end of 2026 is too short for any US ally without nuclear weapons to complete the technical, political, and diplomatic steps required for acquisition.** South Korea and Japan possess advanced nuclear fuel cycles and delivery systems but remain bound by non-proliferation commitments, US extended-deterrence arrangements, and domestic political constraints that have not shifted toward weaponization in recent months. Poland and other NATO states have discussed hosting or sharing arrangements, yet these involve existing US or allied stockpiles rather than independent programs. No official announcements, legislative actions, or verified technical milestones in 2025–2026 indicate an imminent breakout by any ally. The consensus reflects the structural barriers—treaty obligations, verification requirements, and multi-year development timelines—that make a new nuclear-armed US ally before 2027 highly improbable under current conditions.

This market will resolve to "Yes" if credible reports from international nuclear agencies, a claimant government, or a consensus of credible global news sources officially confirm that a US ally which did not possess nuclear weapons as of November 12, 2025, possesses a nuclear weapon by December 31, 2026, 11:59 PM ET.
If a US ally participates in a nuclear sharing agreement that does not include independent control over nuclear weapons, this will not qualify for "Yes" resolution. Only full control over an operational nuclear weapon will count. Any admission from Israel of the possession of a nuclear weapon will not qualify for a "Yes" resolution.
For the purposes of this market, a "US ally" is defined as a country that is a member of NATO or a Major Non-NATO Ally (https://www.state.gov/major-non-nato-ally-status/) as of November 12, 2025. Otherwise, this market will resolve to "No".
