The probability has, trading between 3.1% and 9.5% during the period. For a “Yes” resolution, an agreement on nuclear arms control or strategic weapons limitation must be publicly announced and acknowledged by both the U.S. and Russian governments. Qualifying agreements include treaties, frameworks, or memorandums covering warheads, delivery systems, verification, or strategic stability. An extension, amendment, or replacement of New START qualifies if finalized and announced by both parties within the timeframe. The deal can be bilateral or part of a multilateral framework, and ratification is not required. What would move the number: The approaching deadline of Jan 1, 2027, along with official statements from the White House, State Department, Kremlin, or Ministry of Foreign Affairs—or a consensus of credible reporting—could shift the odds. Any announcement confirming a deal that fits the market’s criteria would be decisive.
An official agreement on nuclear arms control or limitation, publicly announced and acknowledged by both the U.S. and Russia. It must address nuclear warheads, delivery systems, verification, or strategic stability, and can be a treaty, framework, or memorandum.
No. A formal announcement of a concluded agreement is sufficient. Ratification or implementation is not required for the market to resolve to Yes.
It resolves to Yes if an agreement is reached between August 14, 2025 and the market’s end date, otherwise it resolves to No.
Exploratory discussions or stated intent to negotiate, without a finalized and publicly announced agreement, do not qualify. Only concluded agreements acknowledged by both parties count.
The primary resolution source is official statements from the U.S. or Russian governments. A clear consensus of credible reporting confirming a deal can also serve as resolution evidence.
