Extensive damage to Iran's key enrichment facilities from US and Israeli strikes in 2025 and early 2026 has left major sites inoperable, with IAEA verification access suspended since mid-2025 and no confirmed resumption of large-scale uranium enrichment. US intelligence assessments place any potential breakout timeline at roughly one year if Iran decided to pursue weapons-grade material, while remaining 60% enriched stockpiles face uncertainty over survival and location amid ongoing diplomatic talks demanding capacity reductions. Recent satellite indications of activity at secondary sites like Minzadehei reflect reconstruction efforts rather than rapid advancement. This infrastructure and monitoring reality underpins the 96.8% trader consensus against an Iranian nuclear device before 2027, though undetected tunnel operations or accelerated weaponization of surviving material could still shift probabilities if verified.
