Who will attend a round of US-Iran peace talks by December 31?

Platform comparison

Market context

Direct US-Iran peace talks at senior diplomatic level remain absent as of late 2024, with bilateral relations defined by sanctions, proxy conflicts, and limited official engagement channels. The prospect of formal negotiating rounds by end-2026 hinges on significant geopolitical shifts, including potential changes in US administration policy, Iranian domestic political transitions, or third-party mediation breakthroughs. The 2015 Joint Comprehensive Plan of Action (JCPOA) collapse in 2018 and subsequent "maximum pressure" sanctions regime established the baseline from which any resumption would depart.

Historical precedent suggests such talks require months of preparatory backchannel work. The 2015 JCPOA negotiations involved years of preliminary discussions before formal rounds commenced; the 2021-2022 Vienna talks on nuclear restoration similarly required extensive groundwork. Current 12% probability reflects the structural difficulty of convening talks without prior diplomatic thaw, though not impossibility within a 24-month window. Oman and Iraq have historically served as neutral venues; Switzerland and Qatar remain potential hosts.

Key catalysts include the 2024 US presidential election outcome, Iranian leadership transitions, and any major regional escalation or de-escalation events. Traders should monitor statements from US State Department officials, Iranian Foreign Ministry announcements, and third-party mediation initiatives. Recent reporting from Reuters and AFP on indirect talks through intermediaries provides baseline context, though these fall short of the "formal senior-level round" definition required for settlement.
