US-Iran Final Nuclear Deal by…?

Market context

The underlying real-world event is a preliminary memorandum of understanding signed between Washington and Tehran on 15 June 2026, establishing a 60-day ceasefire and diplomatic phase to negotiate a final deal on Iran’s nuclear programme. This framework, set for formal signing in Switzerland on 19 June, explicitly defers resolution on highly enriched uranium stockpiles and enrichment moratoriums to subsequent talks, meaning no binding final instrument exists yet.

Historically, comparable cases such as the 2015 JCPOA negotiations show that initial frameworks often stall when core technical issues like uranium stockpile disposal remain unresolved; experts note Iran’s tendency to prolong talks to extract concessions, with Dan Shapiro of the Atlantic Council warning that no deal may ever materialise, or one reached could be worse than prior diplomatic outcomes[4]. The current 0% crowd-implied probability on the prediction market aligns with this analyst consensus, diverging sharply from the 100% “Yes” odds on a separate Polymarket contract for a deal by 30 June, which appears to misinterpret the preliminary MoU as a final agreement[1].

Traders must monitor the 60-day negotiation window’s technical working groups, scheduled to address sanctions relief and nuclear activities within days, alongside any public statements from US Vice President JD Vance or Iranian Foreign Minister Abbas Araghchi regarding IAEA inspector access and frozen asset releases[3]. Recent Al Jazeera reporting confirms unresolved divergence on nuclear inspector returns and the $12 billion asset release claim, with Washington unconfirmed on the latter, suggesting significant friction remains before a qualifying written instrument can be mutually signed[3].

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 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?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

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 it cost to trade on PolyGram?

Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram triggers a quick verification flow that finishes in minutes.
