Recent US and Israeli strikes in 2025 and early 2026 severely damaged Iran's enrichment facilities at Natanz, Fordow, and Isfahan, eliminating most centrifuges and rendering active uranium enrichment inoperable. US intelligence and IAEA assessments place the current breakout timeline at roughly one year if Tehran decides to pursue weaponization, with no verified signs of resumed cascades or assembly efforts by October 2026. This extended timeline underpins trader consensus that a confirmed nuclear weapon by December 31, 2026, remains improbable. Remaining uncertainty centers on the status of surviving 60% enriched uranium stockpiles in sealed tunnels and any covert reconstruction at sites such as Pickaxe Mountain, though both face significant technical and verification barriers in the narrow window ahead.
