**Trader sentiment on a U.S. nuclear explosive test by late 2026 remains subdued, with implied probabilities in the low single digits to low teens across resolution dates.** The United States has maintained a voluntary moratorium on nuclear explosive testing since 1992, relying instead on the Science-Based Stockpile Stewardship Program, subcritical experiments, and hydrodynamic testing at the Nevada National Security Site to certify warhead reliability. Recent statements from the Trump administration, including October 2025 directives and subsequent Energy Department clarifications, have emphasized non-yield “system tests” and conventional live-fire activities rather than full nuclear detonations. Geopolitical accusations regarding alleged low-yield activities by China and Russia, alongside UN warnings in August 2026 about risks of renewed testing, have kept the issue in focus, but no verified U.S. explosive test has occurred. Key upcoming factors include ongoing nuclear modernization programs, any shifts in stockpile stewardship policy, and diplomatic developments around the Comprehensive Nuclear-Test-Ban Treaty framework.

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 sentiment on a U.S. nuclear explosive test by late 2026 remains subdued, with implied probabilities in the low single digits to low teens across resolution dates.** The United States has maintained a voluntary moratorium on nuclear explosive testing since 1992, relying instead on the Science-Based Stockpile Stewardship Program, subcritical experiments, and hydrodynamic testing at the Nevada National Security Site to certify warhead reliability.
