Iran nuclear test before 2027?
- Iran nuclear test before 2027?5¢
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.
Recent U.S. and Israeli airstrikes in 2025 and early 2026 on enrichment sites at Natanz, Fordow, and Isfahan, followed by additional strikes into spring 2026, have damaged key infrastructure and buried highly enriched uranium stockpiles, pushing back Iran's estimated timeline for weaponization to nine-to-twelve months or longer according to U.S. intelligence assessments. Ongoing diplomatic talks, IAEA monitoring of limited activity, and satellite evidence of reconstruction efforts at hardened or underground locations like Pickaxe Mountain and Taleghan 2 through mid-2026 further indicate that Tehran lacks the immediate capacity or political window for a nuclear test before the end of 2026. This sustained degradation underpins traders' 95.5% implied probability on "No." Even so, accelerated rebuilding aided by foreign suppliers, a shift in Iranian doctrine amid negotiations, or undetected advances at secondary facilities could still alter the short remaining timeline before year-end.
