Note on Middle East Markets: The promise of prediction markets is to harness the wisdom of the crowd to create accurate, unbiased forecasts for the most important events to society. That ability is particularly invaluable in gut-wrenching times like today. After discussing with those directly affected by the attacks, who had dozens of questions, we realized that prediction markets could give them the answers they needed in ways TV news and 𝕏 could not.

This market will resolve to "Yes" if Iran conducts a nuclear test by December 31, 2026 11:59pm ET. Otherwise, this market will resolve to "No".

A nuclear test is defined as the intentional non-combat detonation of a device by Iran 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 Iran may still qualify if a clear consensus of credible reporting attributes the nuclear detonation to Iran. For example, an unclaimed nuclear test analogous to the 1979 "Vela Incident" would count if credible reporting attributes it to Iran.

The resolution source for this market will be a broad consensus of credible reporting.
