Tensions between the United States and Iran have shaped recent geopolitical relations. This market tracks whether a formal diplomatic meeting between US and Iranian officials will occur by April 17, 2026. The current zero percent odds indicate market participants view direct bilateral diplomatic engagement as extremely unlikely in the near term, reflecting the Trump-Vance administration's stated emphasis on sanctions and pressure over dialogue as the primary approach to Iran policy. For resolution purposes, a diplomatic meeting is defined as an official face-to-face negotiation between government representatives, excluding virtual calls or informal contacts. The market uses official state department announcements, public diplomatic records, and international databases as resolution sources. The zero odds reflect market skepticism about near-term US-Iran diplomatic breakthroughs, though geopolitical situations can shift rapidly in response to regional developments or strategic pivots. Market participants trading at zero odds are essentially predicting no substantive diplomatic engagement will be documented by the April 17 deadline, with final resolution occurring on April 30, 2026.
