Market context

Iran has moved from talk to practice: Reuters reported on 6 August that shipping-industry sources were being told a Hormuz passage deal would not be workable, while recent reporting also said Tehran was seeking fees of roughly 5% to 7% of cargo value, with Oman floating lower voluntary charges and Washington opposing any fee at all.[12][15] That leaves the market anchored on a live policy dispute, but with no clean evidence of a broad, formal toll regime being uniformly applied across commercial traffic yet.[12][15]

The useful comparator is the pattern from March and April, when Bloomberg and Reuters described ad hoc payments and Iranian proposals for service charges framed as compensation for navigation, security, and environmental cover, rather than an outright transit toll.[1][14] Reuters also noted that Iran has tried to fold the idea into a longer-term settlement, which matters because this market needs an official announcement and actual collection from generally defined vessels, not isolated demands or one-off payments.[14] That distinction has kept the crowd-implied probability at zero despite repeated signalling.[1][13]

A trader should watch for a formal Iranian government statement, cabinet or ministry guidance, and any published schedule setting who pays, how much, and under what legal label, because Reuters and other outlets have shown Tehran using “service fees” language to stay within a narrower interpretation of international law.[7][13][15] The key dependency is whether any Oman-mediated arrangement or reopened-route protocol turns voluntary contributions into mandatory collection; absent that, even reported payments by some ships may still fall short of the market’s threshold.[1][12][15]

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.
