US intelligence assessments from early May 2026 indicate Iran's timeline to produce a nuclear weapon remains 9-12 months despite US-Israeli airstrikes during the February-April war, which inflicted limited damage on key enrichment facilities like Natanz. IAEA reports confirm Tehran's stockpile of 60% enriched uranium—near weapons-grade—but no verified weaponization advances, with breakout time for fissile material estimated at 1-3 months yet requiring additional steps for a deliverable device. Ongoing US-Iran negotiations, including Iran's softened stance on capping enrichment at 3.5%, signal diplomatic de-escalation, reinforcing trader consensus at 90.8% for "No" before 2027 amid sustained sanctions and monitoring. Late breakthroughs or policy shifts could still alter odds.
