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.

    Iran nuclear test before 2027 remains a long shot despite missile news Polymarket 4%
    • The Polymarket contract on an Iranian nuclear test before 2027 sits at 4%, despite an active week of proliferation headlines.
    • The UN nuclear chief's report that Iran has not repaired damaged facilities is consistent with the market's low probability, the infrastructure for a test appears absent.
    • Trading volume on this contract surged 17,043% day over day, signaling the proliferation headlines are drawing sharp attention even as the price holds low.
    • The Kalshi contract on Trump visiting Iran (CM-EVT-V9QGT2SSP7) sits at just 2%, suggesting the market sees diplomacy as even less likely than a test, both tail risks remain priced near zero.
