US x Iran permanent peace deal by 2026?

Platform comparison

Active sub-markets

Market context

The United States and Iran have not held formal diplomatic relations since 1980, and direct military confrontation has escalated markedly since 2020, including the assassination of General Qasem Soleimani, Iranian ballistic missile strikes on US bases in Iraq, and recurring naval incidents in the Persian Gulf. A permanent peace deal would require explicit mutual recognition of ceasefire terms and an end to active hostilities—a threshold substantially higher than the temporary nuclear agreements (JCPOA) that have repeatedly collapsed. The 0% crowd probability reflects the absence of any active negotiating framework or public statements from either government indicating willingness to pursue such an accord by end-2026.

Historical precedent offers limited encouragement. The Iran–Iraq War (1980–88) ended without a formal peace treaty; the JCPOA (2015) survived only until the US withdrawal in 2018; and subsequent "maximum pressure" sanctions campaigns have hardened both sides' positions. Comparable US–adversary reconciliations (Vietnam, China) required years of backchannel diplomacy before public announcements. The current US administration's posture toward Iran remains hawkish, whilst Iranian leadership has shown no substantive movement toward direct negotiations on military cessation.

Traders should monitor statements from incoming US administrations regarding Iran policy, any UN-brokered diplomatic initiatives, and shifts in regional proxy conflicts (particularly in Syria, Iraq, and Yemen) that might signal changing strategic calculations. The Financial Times and Reuters have reported sporadic indirect talks through intermediaries, though these remain focused narrowly on nuclear compliance rather than permanent military settlement. Without scheduled high-level meetings or declared negotiating positions, the probability faces structural headwinds through the settlement window.

Methodology

Political prediction markets differ structurally from sports betting: thinner liquidity, longer settlement windows, higher sensitivity to single news events. This page shows the live Polymarket quote for US x Iran permanent peace deal by 2026? plus platform attributes for the three reference venues, so you can see at a glance where the deepest market for this question sits.

Resolution & payout

Political markets typically settle on official candidate or agency confirmation. Polymarket uses UMA Optimistic Oracle: a proposer posts the outcome with a bond, the two-hour window opens, then the smart contract pays USDC.

Kalshi settles USD via CFTC clearinghouse, with clearly defined resolution sources (e.g. AP race calls for elections). Betfair settles after the official outcome is registered with the league or agency. Manifold is play-money.
