Iran-Oman Hormuz Management Agreement by 2026?

Platform comparison

Market context

Iran and Oman are close to a shipping-management deal over the Strait of Hormuz, with recent reports saying the talks are in final drafting and that Tehran has agreed route coordinates in principle. Reuters, BBC and Al Jazeera all describe the talks as advanced, but also conditional: Iran has tied any wider reopening to further political terms, including compensation issues and, in some reports, US-related constraints, which means a headline agreement is not the same as a durable operational settlement.[1][3][8][14]

The current **35% YES** implies the market is treating a signed, qualifying instrument before 31 August 2026 as possible but far from certain. That reading fits the recent pattern: the sides have moved from a June joint working-group process to July disagreements over regional management, then to August claims of an “in principle” understanding, which suggests progress but still leaves room for a draft to stall, be narrowed, or fail to match the market’s requirement that the deal must set concrete obligations on managing traffic.[5][6][12][16] On Polymarket, that probability is shown directly; on Kalshi, Betfair or Smarkets, the same event is usually expressed through prices or decimal odds, so traders have to convert the quote into an implied chance and then adjust for fees, spread and market access.

The main catalyst is an official announcement from Tehran and Muscat, ideally a joint statement or signed memorandum that explicitly covers vessel routing, traffic control, permissions or operating rules in the strait. Reuters reported on 8 August that Iran said the deal was “close” but still not enough by itself to reopen the waterway, which is a warning sign for settlement risk because the market requires an agreement, not merely ongoing talks or a partial route plan.[14] Traders should also watch for Oman’s public position, since several reports note that Muscat has been quieter or has proposed broader regional mechanisms that Iran has rejected, and any change in that stance could determine whether the final text is bilateral enough to qualify.[2][15][16]
