**Trader consensus on the low probability of a US ally acquiring nuclear weapons before 2027 stems primarily from the extended timelines required for fissile material production, weaponization, and testing under the Nuclear Non-Proliferation Treaty framework.** Recent developments, including US-backed civil nuclear cooperation deals with South Korea and Saudi Arabia that explicitly emphasize peaceful uses and include legal reaffirmations against weapons development, have advanced enrichment and reprocessing capabilities but remain far from operational arsenals. Heightened regional tensions have fueled public debate and polling support for nuclear options in places like South Korea, alongside discussions of nuclear latency or sharing arrangements in NATO and East Asia, yet no ally has initiated a weapons program that could yield results in the remaining months of 2026. Historical precedents show such efforts span years amid sanctions risks and alliance pressures. Scenarios that could still shift odds include an undisclosed crash program by an ally like South Korea or Saudi Arabia achieving rapid breakout capability, a sudden policy reversal enabling weapons transfer or sharing, or verified completion of a latent program, though these face substantial technical, diplomatic, and legal hurdles.

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".
