The probability of a UNSC resolution has moved as new information emerges. It now sits at 21.0%, having traded between 11.5% and 25.5% over its lifetime. The market resolves to “Yes” if the UN Security Council adopts a resolution endorsing, approving, implementing, giving legal effect to, or incorporating the “final deal” that the US-Iran memorandum of understanding of June 14, 2026 contemplates. The resolution must be adopted by December 31, 2026, at 11:59 PM ET. The final deal is identified through the text of the resolution, official US or Iranian communications, or a consensus of credible reporting; the resolution’s adoption is determined by that same reporting consensus. The deadline is Jan 1, 2027. Developments that could shift the odds include official statements, draft resolutions, or diplomatic signals—particularly from Security Council members. The market ultimately hinges on whether credible reporting confirms a qualifying resolution by the cutoff.

FAQ

The UN Security Council must pass a resolution that endorses, approves, implements, gives legal effect to, or incorporates the “final deal” referred to in the June 14, 2026 US-Iran memorandum of understanding. This must occur before the deadline of December 31, 2026, at 11:59 PM ET.

What defines the “final deal”?

It is the diplomatic agreement contemplated by the June 14, 2026 MOU, as identified through the resolution’s text, official statements by the US or Iran, or a consensus of credible reporting.

How is the resolution’s adoption verified?

By a consensus of credible reporting, meaning major news outlets and official sources agree that the Security Council has acted.

What happens if the UNSC does not act by the deadline?

If no qualifying resolution is adopted by December 31, 2026, at 11:59 PM ET, the market resolves to “No.”
