US-Iran Final Nuclear Deal by…?

Platform comparison

Market context

The real-world backdrop is a June diplomatic instrument that opened a 60-day path for the United States and Iran to keep negotiating a fuller nuclear settlement, but the text and the public read-outs have left several core issues unresolved. Reuters reported on 12 June that a senior US official said a signing could come “in the coming days”, while later reporting showed the sides still haggling over sanctions relief, inspections and nuclear terms, which helps explain why the crowd is pricing the contract at 0% YES even with a live negotiation track.[10][1][4]

Historical comparables argue for caution on jumping from an interim understanding to a final, signed deal. Earlier rounds in Geneva and Doha produced “significant progress” and “guiding principles”, yet Reuters said the Doha talks ended with no sign of headway on a lasting peace and even focused on issues supposedly settled two weeks earlier.[2][3][4] That pattern matters for cross-platform odds: prediction markets often discount open-ended diplomacy far more aggressively than headline-driven analyst commentary, and sportsbook-style lines would usually need a documented signing timetable or formal adoption language before moving much above long-shot territory. The market’s 0% implied probability is therefore consistent with a sceptical read of an interim framework rather than a settled contract outcome.[2][4][10]

Traders should watch for whether the talks convert into a formally adopted text, not just more statements about progress. The most important catalysts are any joint announcement from Washington and Tehran, confirmation from mediators such as Qatar, Pakistan or Oman, and whether working groups on nuclear, sanctions and monitoring produce a document that meets the market’s “written diplomatic instrument” standard.[1][5] Reuters also noted that the US and Iran were still discussing maritime traffic and frozen funds in early July, which implies the remaining dependency chain is diplomatic and procedural rather than purely rhetorical.[4] If there is no explicit signature, adoption or mutually accepted final text before the 31 August settlement window closes, the default path remains No.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, 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.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
