Recent indirect US-Iran contacts on the UNGA sidelines in New York, mediated primarily by Qatar, have sustained trader focus on that location for any follow-on senior meeting, while earlier 2026 sessions in Switzerland and shuttle diplomacy via Oman and Pakistan highlight established neutral venues. Stalled progress after Washington rejected Tehran's seven-day Hormuz reopening proposal, sequencing disputes over sanctions relief and nuclear issues, and the approach of US midterms have elevated the "no meeting by December 31" outcome to the lead. Qatar's ongoing role as the principal intermediary underpins its second-place positioning, with lower probabilities for traditional European hosts or other regional states reflecting limited recent signals of movement toward those sites.
