US x Iran permanent peace deal by 2026?

Market context

The question concerns whether the United States and Iran will formalise a permanent cessation of military hostilities through an explicit bilateral agreement by end-2026. The definition requires clear language signalling a lasting end to conflict, ruling out temporary ceasefires, sanctions relief without military guarantees, or incremental confidence-building measures that fall short of a definitive peace settlement.

Historical precedent suggests such agreements are rare between these parties. The 2015 Joint Comprehensive Plan of Action (JCPOA) addressed nuclear matters but explicitly excluded military hostilities or broader conflict resolution. The US withdrawal in 2018 and subsequent Iranian retaliation—including the January 2020 ballistic missile strikes on US bases in Iraq—demonstrate how quickly diplomatic frameworks can collapse without permanent peace architecture. No comparable US-Iran military peace accord exists in the post-1979 record. Traders should note that even the most optimistic diplomatic scenarios in recent years have targeted nuclear constraints or prisoner exchanges rather than permanent military de-escalation frameworks.

Current catalysts remain sparse. The incoming US administration's Iran policy stance will be critical; statements from late 2024 suggest a harder line than the previous approach. Iranian domestic politics, particularly post-election consolidation, affect negotiating capacity. Traders monitoring this market programmatically should track statements from US State Department and Iranian Foreign Ministry, announcements of direct bilateral talks (distinct from nuclear negotiations), and any UN-mediated initiatives. The 0% crowd probability reflects the absence of active peace negotiations and structural barriers to agreement within the two-year window.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.
