Iran agrees to end enrichment of uranium by June 30?

Platform comparison

Market context

Iran's nuclear programme remains a focal point of international diplomacy. The question of whether Tehran will publicly commit to halting uranium enrichment by mid-2026 hinges on the trajectory of US–Iran relations under the incoming Trump administration and any parallel negotiations with Israel or European powers. Historically, Iran has agreed to enrichment caps under the Joint Comprehensive Plan of Action (JCPOA) signed in 2015, though that agreement collapsed after US withdrawal in 2018. Since then, Iran has accelerated enrichment to near-weapons-grade levels, making any reversal a significant diplomatic shift. The 12% implied probability reflects the low baseline expectation of such a reversal within eighteen months, given the current geopolitical stance and Iran's stated position on sovereignty over its nuclear activities.

Catalysts for movement include direct US–Iran talks, potential Israeli pressure following regional escalations, or European Union mediation efforts. Trump's previous "maximum pressure" campaign and his stated preference for renegotiating nuclear deals create uncertainty about whether his administration will pursue engagement or further isolation. Any formal announcement—whether unilateral, bilateral with the US, or multilateral—qualifies for resolution. Traders should monitor statements from Iran's Foreign Ministry, IAEA reports on enrichment levels, and scheduled diplomatic meetings. Recent reporting from Reuters and the International Atomic Energy Agency indicates Iran continues expanding its enrichment capacity, suggesting movement toward a public commitment remains contingent on substantial external pressure or internal policy shifts unlikely within the settlement window.
