Market context
The United States and Iran have formally signed a memorandum of understanding that halts active conflict and initiates a 60-day negotiation window for a final peace deal, with the Strait of Hormuz reopening as a key immediate outcome. This market currently sits at a 0% implied probability for the US withdrawing from these talks, reflecting a consensus that the US is the favourite to complete the process given the substantial concessions already made, including $300 billion in reconstruction aid and sanctions relief. Historical precedents from the 2015 Iran nuclear deal and the 1978 Camp David Accords suggest that once a framework is signed with such high-value incentives locked in, unilateral termination by the initiating power is rare unless a fundamental breach occurs, making the current pricing efficient for the underdog scenario.
Traders should monitor the scheduled High Level Committee meetings in Switzerland and any public statements from the White House regarding the 30-day naval blockade withdrawal deadline, as delays here could signal friction. A recent CNN report confirmed the formal signing is set to initiate the negotiation phase, meaning the next critical dependency is the final agreement on Iran’s uranium enrichment levels by late August [1]. Contrarian value might only appear if the US announces a failure to secure a down-blending mechanism for enriched material, but until such a specific catalyst emerges, the consensus that the US will honour the MOU remains the dominant and logical position.

Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
