US-Iran Final Nuclear Deal by…?

Platform comparison

Market context

The United States and Iran have announced a framework to end their conflict, triggering a 60-day diplomatic window to negotiate a final deal on Iran’s nuclear programme. This specific market asks whether a mutually signed written instrument confirming that final deal will exist before August 2026. In prediction markets, a YES share pays out if the event occurs, while a NO share pays out if it does not; here, the crowd currently implies a 0% chance of a YES outcome, suggesting deep scepticism that a formal agreement will be reached.

Historically, such high-stakes negotiations between Washington and Tehran have frequently stalled over core issues like enriched uranium stockpiles and sanctions relief, with past attempts often collapsing before a final signature. Experts note that Iran is skilled at prolonging talks to extract concessions, and many analysts believe a deal, if reached, may be weaker than pre-war diplomatic efforts[5]. The current 0% probability reflects this pattern of unresolved tensions, particularly regarding the status of Iran’s nuclear reserves and the precise details of sanctions waivers, which remain contentious even after the initial Memorandum of Understanding was signed[3].

Traders should monitor upcoming announcements on the release of frozen Iranian assets and the return of international nuclear inspectors, as these are critical dependencies for a final deal. Recent reports indicate that while Iran claims $12 billion in assets will be unfrozen, US officials have denied this, and disagreements persist on whether inspectors will access damaged sites[3]. Any shift in the stance of US President Donald Trump, who has stated he will act if Iran fails to uphold commitments, or a breakdown in talks due to regional instability like the attack on Lebanon, could further cement the market’s NO outcome[3][8].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

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 Prediction Market UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
