Trader consensus on Polymarket reflects a 90% implied probability that Iran will not develop a nuclear weapon before 2027, driven by recent IAEA assessments confirming no diversion of enriched uranium for weaponization despite Iran's stockpile of near-weapons-grade material at 60% purity. U.S. intelligence maintains Iran has not restarted a coordinated weapons program since halting key activities in 2003, while Israeli airstrikes on October 26 targeted missile production sites rather than nuclear facilities, avoiding escalation. IAEA Board censure of Iran on October 4 for non-cooperation prompted vows of new centrifuges but no observed shift toward bomb-grade 90% enrichment. Ongoing sanctions, Mossad sabotage setbacks, and Supreme Leader Khamenei's fatwa against nuclear arms create formidable barriers, though U.S. election outcomes or regional conflicts could alter trajectories.
