**New START expired on February 5, 2026, ending the last formal U.S.-Russia strategic arms control treaty limiting deployed warheads and delivery systems.** Russia had proposed in September 2025 to voluntarily observe the treaty’s central numerical limits for one additional year if the United States did the same, but Washington declined a formal extension and instead signaled interest in negotiating a “new, improved, and modernized” agreement. U.S. statements have emphasized the need for multilateral talks that include China and address a broader range of systems and verification issues. Both sides have indicated they are currently observing the prior limits informally, pending further diplomacy. Recent high-level U.S.-Russia contacts tied to Ukraine peace efforts have been described by the Kremlin as potentially opening pathways to restored bilateral relations, though no specific nuclear negotiations timeline or framework has been confirmed. Trader sentiment reflects the absence of a successor deal, the expiration of binding constraints, and uncertainty over whether ongoing diplomatic channels will produce a new agreement in the near term.

Only agreements that are publicly announced and acknowledged by both the U.S. and Russia will qualify. The agreement must pertain to nuclear arms control or limitation—such as a treaty, framework, or memorandum—addressing matters including (but not limited to) nuclear warheads, delivery systems, verification mechanisms, or strategic stability.
An extension, amendment, or replacement of the New START treaty will qualify, provided it is publicly announced as a concluded agreement by both parties within the time frame. Exploratory discussions or stated intent to extend without a finalized agreement will not qualify.
Agreements that include both the United States and Russia as named parties—whether bilateral or as part of a broader multilateral framework—will qualify, provided the agreement directly addresses nuclear arms control.
The agreement does not need to be ratified or implemented for this market to resolve "Yes"; a formal announcement of a concluded agreement is sufficient.
The primary resolution source for this market will be official statements from the U.S. government (e.g., the White House, State Department) and/or the Russian Federation (e.g., the Kremlin, Ministry of Foreign Affairs). However, a clear and overwhelming consensus of credible reporting confirming that such an agreement has been reached will also qualify.
