Iran agrees to end enrichment of uranium by July 31?

Platform comparison

Market context

Iran has moved closer to a possible nuclear understanding in the past few days, with Reuters reporting on 14 June that a draft US deal would leave Tehran at the current status quo while it refrains from further uranium enrichment pending a final agreement. That matters for this market because the resolution requires a public Iranian pledge to end *all* enrichment by 31 July 2026, not just a pause or a cap, so the gap between a freeze and a full cessation is still the key hurdle.[1]

The historical pattern argues for caution around a 56% implied chance. Iran has repeatedly expanded its enrichment programme since the US left the JCPOA, including work at 60% purity and broader centrifuge build-out, while the IAEA has continued to report substantial stocks of enriched uranium and reduced transparency.[5][7][9] Even in periods of negotiation, previous deals have typically centred on limits, monitoring, or temporary restraints rather than a complete, durable halt to enrichment, which makes a clean public commitment comparatively rare.[3][5][8]

Traders should watch for any joint statement from Washington and Tehran, Iranian state media reports, or IAEA-related diplomacy that converts a framework into a signed text. Reuters’ reporting suggests there is still a defined negotiation window rather than an immediate final accord, with a final agreement to be considered over the following 60 days, so the main catalyst is whether that process produces a written Iranian pledge before the July deadline.[1][4] Any wording limited to “pause”, “freeze”, “suspension”, or “verification” would likely fall short, whereas a clear public commitment to end enrichment entirely would be market-relevant immediately.

Methodology

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

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.
