| IAEA visits Isfahan, Fordow, or Natanz nuclear site by July 31? | 0.0% | 0.0 |

The market's assessment has shown variability, with the current reading at 14.0%. Over the period, it has ranged from 12.5% to 24.0%. The contract resolves to 'Yes' if one or more IAEA officials physically visit the Isfahan Nuclear Technology Center, the Fordow Fuel Enrichment Plant, or the Natanz Nuclear Facility before the expiry. The visit must involve physical presence within the recognized boundaries of one of these sites; virtual inspections, visits to other locations in Iran, or visits to the separate Pickaxe Mountain area do not qualify. IAEA officials are defined as individuals acting in an official capacity, including inspectors, staff, and the Director General. The resolution relies on official IAEA statements and a consensus of credible reporting. The market's price reflects the likelihood that a qualifying visit occurs before the deadline Jan 1, 2027. Any official confirmation from the IAEA or credible press reports of a physical visit to one of the listed sites would settle the market to 'Yes'; otherwise, it resolves to 'No' at expiry. No other scheduled events affect the outcome directly; the key conditions are time, location, and the physical-access requirement.
