US-Iran Final Nuclear Deal by…?

Market context

A written US-Iran nuclear framework is already in place, but the market still requires a **mutually signed or formally adopted final instrument** by 31 August 2026. The latest public reports show the sides have moved into a 60-day bargaining phase after announcing an initial deal on 17 June, with sanctions relief, uranium limits and wider security issues all still being negotiated rather than fully settled.[2][3]

That is why the current 1% crowd view is still understandable: comparable Iran talks have often produced interim understandings, technical working groups and positive language without a durable final accord. BBC reporting on the Geneva round noted “significant progress” but also unresolved disputes over enrichment, stockpile treatment and sanctions removal, while earlier nuclear negotiations broke down in 2025 before the current track reopened in 2026.[1][6] In other words, the headline framework is real, but the hard part is converting it into a text both capitals will actually endorse.

The key catalysts are the follow-up technical talks, any statement from mediators Qatar, Pakistan or Oman, and whether Washington and Tehran confirm draft language on uranium enrichment and sanctions waivers. AP reported that the June agreement began a 60-day timeline and left room for negotiations on the future of Iran’s programme, so traders should watch for fresh signing dates, an extension of the talks, or any reversal tied to military pressure or renewed strikes.[2][3] BBC also reported that technical discussions were due in Vienna, which gives a concrete near-term schedule to monitor.[1]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
