US-Iran Hormuz Agreement by 2026?

Platform comparison

Market context

Polymarket is pricing this contract at **69% YES**, so the market is leaning towards a US-Iran diplomatic instrument on Hormuz landing before the 31 August 2026 deadline, but not treating it as a lock. On Polygon, with USDC collateral and conditional tokens, that price reflects traders’ view of the probability that an official agreement meeting the market’s wording is announced in time, rather than a judgement on whether shipping actually normalises in practice.

The main comparison is the June memorandum of understanding, which already tied together a ceasefire, sanctions waivers and a framework for safer passage through the Strait of Hormuz, including a 60-day implementation period and further technical talks. Reuters reported on 1 July that negotiators were still discussing maritime traffic and financial incentives rather than the harder unresolved issues, which is relevant because this market needs a qualifying diplomatic agreement, not just a verbal understanding or temporary de-escalation.[5] The fact that the Treasury later waived sanctions on Iranian oil and petroleum products through 21 August also shows that some deal mechanics have already been implemented, but the contract resolves only if the agreed Hormuz-related obligations are formally announced by the deadline.[1][9]

For traders, the key catalysts are official statements from Washington or Tehran, any scheduled signing or follow-up session, and whether Oman’s mediation produces a new maritime route or a broader finalised text. Al Jazeera reported on 2 August that Iranian officials said talks with Oman were in their “final stages”, while Reuters’ earlier reporting suggests the market may react sharply if those talks move from framework language to a signed instrument with explicit shipping commitments.[7][18] The practical question on Polymarket is whether a new announcement crosses the threshold from ongoing negotiations into a distinct diplomatic agreement that clearly binds both sides on Hormuz traffic.
