This market will resolve to "Yes" if Russia conducts a nuclear test by the listed date (ET). Otherwise, this market will resolve to "No". A nuclear test is defined as the intentional non-combat detonation of a device by Russia that produces a nuclear chain reaction (fission or fusion), regardless of yield. Accidents, radiological dispersal devices (bombs that spread radioactive material using conventional explosives such as "dirty bombs"), or actions by third parties will not count toward this market's resolution. Tests not explicitly claimed by Russia may still qualify if a clear consensus of credible reporting attributes the nuclear detonation to Russia. For example, an unclaimed nuclear test analogous to the 1979 "Vela Incident" would count if credible reporting attributes it to Russia. The resolution source for this market will be a broad consensus of credible reporting.
Russia has maintained its moratorium on explosive nuclear tests since 1990 while modernizing delivery systems and conducting exercises, including a May 2026 Sarmat ICBM launch and strategic force drills. Officials have signaled readiness to respond in kind to any U.S. or other nuclear explosive test, following 2025 statements on preparations tied to New START expiration and bilateral rhetoric, but have emphasized reciprocity rather than unilateral action. Facilities at Novaya Zemlya remain maintained, and satellite monitoring continues amid broader concerns over possible low-yield activities. Trader assessments reflect these constraints alongside the absence of confirmed explosive tests or imminent triggers through mid-2026. Scheduled diplomatic contacts or escalation in Ukraine-related tensions could influence timing within any resolution window.
