Iran agrees to end enrichment of uranium by June 30?

Platform comparison

Market context

Iran has not publicly pledged to end all uranium enrichment by June 30, 2026, which explains the current 0% crowd-implied probability for a "Yes" resolution. Historically, Iran’s nuclear commitments have been fragile and often reversed; the 2015 JCPOA restricted enrichment to 3.67% but was abandoned by Tehran in 2019 after the US withdrew, leading to enrichment up to 60% and a growing stockpile of highly enriched material[5][6]. Even the recent draft memorandum of understanding from June 2026, which secured a ceasefire and Strait of Hormuz reopening, only commits Iran not to *develop or acquire* nuclear weapons while maintaining current nuclear activities pending further talks, not to end enrichment itself[3][4].

Traders should monitor for any official announcement from Iran’s Ministry of Foreign Affairs or the US State Department confirming a binding agreement that explicitly halts enrichment, as partial frameworks or non-binding statements do not qualify[2]. Key catalysts include the outcome of the 60-day ceasefire talks initiated on June 15, which are expected to address unresolved nuclear issues including enrichment levels and stockpile status[4]. A recent Reuters report notes the draft deal includes a nuclear limits clause and an oil sanctions waiver, but it does not specify a full cessation of enrichment, underscoring the gap between current negotiations and the market’s strict resolution criteria[9]. Programmatically, this market would be approached by setting conditional orders triggered only upon verified, dual-official confirmations of a formal, binding accord that meets the exact enrichment cessation requirement.
