Trader consensus on "No" at 87.5% for Iran developing a nuclear weapon before 2027 stems primarily from IAEA reports confirming rapid uranium enrichment to near-weapons-grade levels (60% purity) but no diversion of material or evidence of active weaponization. US intelligence assessments hold that Iran suspended its structured nuclear weapons program in 2003, with a potential breakout timeline of 1-2 years from a political decision—insufficient for a deliverable bomb by 2026 absent major escalation. Recent catalysts include the IAEA's November 2024 censure of Iran for non-cooperation, Tehran's retaliatory centrifuge expansions, stalled JCPOA revival talks, and post-US election signals of intensified sanctions and Israeli vigilance, all sustaining market expectations of continued threshold status over outright pursuit.
