This prediction market addresses the possibility of a nuclear weapon detonation occurring anywhere on Earth or in space between November 5, 2025, and June 30, 2026. The market resolves to 'Yes' for any nuclear detonation, including offensive military use, nuclear testing, or an accidental explosion. It resolves to 'No' if no such event occurs. The market excludes failed launches or non-nuclear radiological devices. This topic has gained attention due to heightened geopolitical tensions involving nuclear-armed states and the erosion of longstanding arms control agreements. The specified timeframe coincides with political transitions and military planning cycles in several key nations, making it a period analysts view as potentially volatile. Interest stems from a combination of strategic analysis, intelligence assessments of nuclear postures, and public concern about the re-emergence of nuclear threats as a central feature of international relations. The market provides a mechanism to aggregate diverse perspectives on what many consider a low-probability but extremely high-consequence global risk.

Historical Context

The only wartime use of nuclear weapons occurred in August 1945, when the United States detonated atomic bombs over Hiroshima and Nagasaki, Japan. The Cold War that followed was defined by the nuclear arms race between the U.S. and the Soviet Union, bringing the world to the brink of nuclear exchange during the 1962 Cuban Missile Crisis. This period of extreme risk led to the establishment of arms control frameworks, including the 1963 Partial Test Ban Treaty, the 1968 Nuclear Non-Proliferation Treaty (NPT), and later agreements like START. The last known nuclear test by a recognized nuclear weapon state was conducted by China in 1996. Since the NPT entered into force, only four countries have tested nuclear weapons for the first time: India and Pakistan in 1998, North Korea in 2006, and most recently, North Korea's sixth test in 2017. The Comprehensive Nuclear-Test-Ban Treaty (CTBT) of 1996 has been signed by 187 states but has not entered into force due to the non-ratification by eight specific countries, including the United States and China. The post-Cold War reduction in nuclear stockpiles and testing has recently reversed, with modernization programs and the collapse of key treaties like the Intermediate-Range Nuclear Forces (INF) Treaty in 2019.
