US x Iran permanent peace deal by 2026?

Market context

Polymarket currently prices a permanent US-Iran peace deal by end-2026 at 0%, reflecting the market's assessment that a binding agreement ending military hostilities between the two nations is extraordinarily unlikely within the next two years. The contract trades on Polygon as conditional USDC tokens, with settlement contingent on explicit language from both governments confirming a lasting cessation of military operations rather than a temporary ceasefire or partial accord.

Historical precedent offers limited encouragement. The 2015 Joint Comprehensive Plan of Action (JCPOA) was explicitly framed as a nuclear agreement rather than a peace deal, and the US withdrew unilaterally in 2018. No comprehensive military peace accord between Washington and Tehran has existed since the 1979 revolution. The Iran-Iraq War (1980–88) ended through UN mediation without US involvement. Recent proxy conflicts in Yemen, Syria, and Iraq have intensified rather than de-escalated, with neither side signalling appetite for permanent military settlement. The 0% pricing reflects this structural absence of momentum.

Traders monitoring this contract should track statements from incoming US administrations regarding Iran policy, any multilateral diplomatic initiatives through European intermediaries, and escalation patterns in the Strait of Hormuz or regional proxy theatres. The International Atomic Energy Agency's quarterly reports on Iranian nuclear compliance remain a barometer of broader diplomatic temperature. Congressional positions on sanctions relief—a likely prerequisite for any permanent deal—will constrain executive negotiating room. The settlement window's two-year horizon compresses an already remote probability further, as major policy shifts typically require 18+ months of preliminary backchannel work before public announcement.

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.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
