Recent U.S. and Israeli airstrikes in 2025 severely damaged or destroyed Iran's key uranium enrichment sites at Natanz, Fordow, and related facilities, while leaving uncertainty over surviving stockpiles of 60 percent enriched uranium now stored in tunnels. IAEA inspectors have had no access to enrichment sites since June 2025, and U.S. intelligence assessments indicate Iran has not resumed enrichment or attempted rapid reconstitution of its program. Estimates place the time required to produce a weapon, if Tehran decided to pursue one, at roughly one year or longer from current conditions. Trader consensus at 96.3 percent against an Iranian nuclear weapon before 2027 reflects these setbacks, ongoing sanctions, and lack of verified breakout activity. Late shifts could occur if Iran achieves undetected enrichment of remaining material or accelerates assembly amid reduced oversight.
