About this market
Russia maintains its moratorium on explosive nuclear tests while advancing strategic delivery systems, as shown by recent successful ICBM launches including a Yars system from Plesetsk in late August 2026 and the Sarmat in May. These training and combat evaluations, alongside large-scale strategic forces exercises simulating nuclear authorization procedures, signal readiness without crossing into actual detonations. Ongoing diplomatic contacts, such as the CIA director’s Moscow visit, and Russia’s 2023 CTBT de-ratification reflect conditional posture tied to U.S. actions. Trader consensus assigns low probabilities to near-term tests because no explosive events have occurred despite heightened rhetoric and site activity, with resolution hinging on verifiable chain-reaction detonations rather than missile or simulation activity.
