Iran-Oman Hormuz Management Agreement by 2026?

Platform comparison

Market context

Iran and Oman are in active talks over a formal arrangement to manage shipping through the Strait of Hormuz, with recent reporting saying the two sides are close to a draft deal but have not yet settled every condition. Reuters reported on 8 August that Tehran said an agreement was “close” yet still dependent on wider issues, while earlier Reuters and Bloomberg coverage described a joint working group, route discussions, and a proposal that could split traffic management by direction.[13][4][7]

The current **38% YES** looks broadly consistent with a market that is pricing in serious negotiation progress but not a done deal. Comparable disputes over chokepoint access often reprice sharply on wording, because these contracts usually hinge on whether there is an *official diplomatic instrument* rather than a political statement or working-level understanding. That matters here: Oman’s July proposal for joint regional management was reportedly rejected by Iran, before later reports shifted to a narrower bilateral framework and finally to an agreement “in the final stages”.[14][15][2] On Polymarket, the market is shown as an implied probability; on Kalshi, the same view is typically expressed as a price around 38 cents, whereas Betfair and Smarkets quote decimal odds and then deduct exchange commission, so headline prices are not directly comparable.

The key catalysts are any signed joint statement, foreign-ministry readout, or state-media publication that names obligations on routing, fees, or traffic control. Reuters’ 5 August and 8 August reports are especially relevant because they point to a draft already on the table and to unresolved conditions, including Iran’s demand for broader concessions and disagreement over who controls ships on each leg of the strait.[17][13] Traders should also watch for confirmation from Muscat, because the market description requires a diplomatic agreement between Oman and Iran, not just an Iranian announcement or a procedural memorandum.[1][3]

Methodology

We read Iran-Oman Hormuz Management Agreement by 2026? from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live mid is the canonical probability; the side-by-side columns benchmark fees, KYC, settlement currency and deposit rails so you can choose the venue that fits your jurisdiction and trade size.

Resolution & payout

Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.

Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
