US intelligence assessments from early May 2026 indicate Iran's timeline to produce a nuclear weapon remains 9-12 months, unchanged despite US-Israeli airstrikes since February that targeted nuclear sites like Natanz but caused limited damage to fortified underground facilities and left highly enriched uranium stockpiles largely intact. IAEA reports confirm no evidence of active weaponization, with ongoing US-Iran negotiations via Omani mediators stalling over enrichment limits and verification. Traders' 91% implied probability on "No" reflects this extended breakout timeline—extending into mid-2027 at earliest—amid diplomatic pressures, sanctions, and risks of further military action, though a sudden regime decision to sprint could shift odds.
