This market will resolve to "Yes" if the US 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 the US 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 US may still qualify if a clear consensus of credible reporting attributes the nuclear detonation to US. For example, an unclaimed nuclear test analogous to the 1979 "Vela Incident" would count if credible reporting attributes it to the US. The resolution source for this market will be a broad consensus of credible reporting.Trader consensus prices a low 12% chance of a U.S. nuclear test by December 31, 2026, anchored by the 34-year testing moratorium since 1992 and ongoing stockpile stewardship programs that certify warhead reliability without explosions. President Trump's October 2025 order to resume testing prompted Department of Energy and Defense Department assessments, with a top official stating in March 2026 that underground tests at the Nevada National Security Site remain under review amid Russian and Chinese nuclear advancements. No preparations or dates have materialized, facing congressional budget hurdles, Comprehensive Nuclear-Test-Ban Treaty pressures, and diplomatic risks. Key watchpoints include National Nuclear Security Administration reports and fiscal year 2027 appropriations votes.
