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

Platform comparison

Market context

Formal diplomatic talks between the United States and Iran on core bilateral issues remain rare and fragile. A YES resolution requires at least one senior-level negotiating round—involving authorised officials from both capitals meeting in person—to occur within the next two years. A trader holding a YES share profits if such talks materialise; a NO share pays out if no qualifying round takes place by year-end 2026. The 12% probability reflects the current market consensus that this outcome is unlikely but not implausible.

Historical precedent suggests the bar is genuinely high. The last substantive US-Iran diplomatic engagement at senior level was the Joint Comprehensive Plan of Action (JCPOA) negotiations, which concluded in 2015 and involved multiple rounds over nearly two years. Since the US withdrawal in 2018, direct talks have been sporadic and largely indirect, mediated through intermediaries or conducted at lower levels. The 2021–2022 Vienna negotiations over JCPOA restoration involved Iranian and US delegations but proceeded through European intermediaries rather than direct bilateral rounds. No formal bilateral peace talks have occurred since then, establishing a baseline of diplomatic distance that traders should weigh against the 12% probability.

Catalysts to monitor include shifts in US administration policy (particularly relevant given the 2024 presidential election cycle), Iranian domestic political changes, and any escalation or de-escalation in regional tensions that might create diplomatic openings. Announcements from the US State Department, Iranian Foreign Ministry, or third-party mediators (notably European powers or the UN) would signal movement toward talks. Recent reporting from Reuters and AP News has noted continued sanctions pressure and rhetorical hostility rather than diplomatic overtures, suggesting the near-term environment remains unfavourable for formal negotiations.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Market UK, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
