Recent military strikes in 2025 and early 2026 severely damaged Iran's key enrichment facilities at Natanz, Fordow, and Isfahan, trapping much of its approximately 400 kg stockpile of 60% enriched uranium under rubble and rendering centrifuges largely inoperable. IAEA reports through September 2026 confirm continued denial of access to enrichment sites, with no verified resumption of enrichment or weaponization activities, while satellite imagery shows defensive reinforcements and limited reconstruction at buried sites like Pickaxe Mountain but no breakout-scale progress. Ongoing diplomatic frictions, including the collapse of a June 2026 U.S.-Iran MOU and blocked UN resolutions, reinforce trader views that technical and political barriers make a completed nuclear device before 2027 improbable. Scenarios that could shift odds include undetected recovery of the stockpile for rapid further enrichment or external technical assistance accelerating timelines.
